welcome to another tech stuff Tuesday
00:00:02.210 00:00:02.220 this week we're gonna talk about super
00:00:04.160 00:00:04.170 capacitors when you would use them why
00:00:06.559 00:00:06.569 you should use them when you shouldn't
00:00:08.210 00:00:08.220 use them how you assemble a bank of them
00:00:10.940 00:00:10.950 we're going to go over all that stuff
00:00:12.470 00:00:12.480 and have a little bit of explanation of
00:00:14.930 00:00:14.940 all these applications what we've got
00:00:17.900 00:00:17.910 here is definitely an excess power
00:00:20.420 00:00:20.430 supercell from EMF car audio comm this
00:00:24.590 00:00:24.600 particular example is two point eight
00:00:26.480 00:00:26.490 five volts there are other versions of
00:00:29.630 00:00:29.640 capacitors and one thing you can look at
00:00:32.600 00:00:32.610 with them even the same between the same
00:00:34.490 00:00:34.500 make is they may have a different
00:00:36.410 00:00:36.420 voltage you might be two point seven or
00:00:37.910 00:00:37.920 two point six two point five and we'll
00:00:40.040 00:00:40.050 get into why that matters and then we
00:00:41.690 00:00:41.700 have the capacity is three thousand one
00:00:43.610 00:00:43.620 hundred and fifty farad's out of this
00:00:46.549 00:00:46.559 one capacitor years ago in the past you
00:00:49.130 00:00:49.140 may have had somebody say I have a
00:00:50.330 00:00:50.340 capacitor and it might have been a one
00:00:52.220 00:00:52.230 farad and it'll been a little bit larger
00:00:54.650 00:00:54.660 than this around the same diameter maybe
00:00:57.170 00:00:57.180 a little bit larger and just a little
00:00:58.790 00:00:58.800 bit taller and it was one farad and it
00:01:01.549 00:01:01.559 was intended to be used on a twelve volt
00:01:03.349 00:01:03.359 system now those are essentially
00:01:06.530 00:01:06.540 worthless in car audio if you have a
00:01:08.929 00:01:08.939 high current draw those can actually
00:01:11.030 00:01:11.040 cause a loss of power the amp this gets
00:01:13.580 00:01:13.590 completely depleted and then you end up
00:01:16.280 00:01:16.290 having a low voltage scenario it's
00:01:18.350 00:01:18.360 trying to level out where your source
00:01:19.640 00:01:19.650 coming in is and this is a buffer it
00:01:22.700 00:01:22.710 completely depletes this so you have low
00:01:25.490 00:01:25.500 voltage on this end where the amplifier
00:01:27.140 00:01:27.150 might be but on this own the charging
00:01:29.539 00:01:29.549 side where you might have lights and
00:01:32.359 00:01:32.369 that kind of thing where all of a sudden
00:01:33.890 00:01:33.900 this is not dimming as badly giving you
00:01:35.569 00:01:35.579 the impression you're actually doing
00:01:37.609 00:01:37.619 something but in reality you have lower
00:01:39.890 00:01:39.900 power at the amp which is not affecting
00:01:41.870 00:01:41.880 performance at all so we don't really
00:01:44.450 00:01:44.460 see those too often anymore we don't use
00:01:46.639 00:01:46.649 them anymore they generally don't work
00:01:48.679 00:01:48.689 sometimes they be 2 farad same kind of
00:01:50.929 00:01:50.939 thing and if you actually check the
00:01:52.580 00:01:52.590 peasants of those old ones I might find
00:01:54.920 00:01:54.930 that that are labeled 1 farad actually
00:01:58.399 00:01:58.409 has something else in the canister and
00:01:59.959 00:01:59.969 it was not actually one farad at all it
00:02:02.630 00:02:02.640 may have been much much much less and
00:02:04.609 00:02:04.619 those go with the cheap things you get
00:02:06.649 00:02:06.659 we pay for that kind of thing so we
00:02:09.800 00:02:09.810 don't use those this is
00:02:11.120 00:02:11.130 the newer technology with the super
00:02:14.330 00:02:14.340 capacitors so on these like I said it's
00:02:18.860 00:02:18.870 2.8 5 volts and but we need it to
00:02:21.770 00:02:21.780 operate on a 12 volt system and a 12
00:02:24.590 00:02:24.600 volt system you're going to charge
00:02:25.700 00:02:25.710 around 14 point 4 volts so what we're
00:02:28.760 00:02:28.770 gonna do is we need enough of these
00:02:31.780 00:02:31.790 wired in series to be a usable level so
00:02:36.680 00:02:36.690 we're going to use five of these and if
00:02:38.870 00:02:38.880 you do the math on that you're gonna
00:02:41.120 00:02:41.130 come just under 14 point 4 volts now
00:02:43.790 00:02:43.800 that's fine because there actually is a
00:02:47.120 00:02:47.130 little bit of a tolerance in these I
00:02:49.490 00:02:49.500 believe it's 10% that you can safely go
00:02:51.740 00:02:51.750 over people have said that you can go
00:02:54.620 00:02:54.630 over that I don't recommend that but
00:02:56.510 00:02:56.520 going to 14 point 4 volts with a 2.8 5
00:03:00.800 00:03:00.810 volt capacitor with 5 of them in series
00:03:03.500 00:03:03.510 you can do safely just fine so first
00:03:06.800 00:03:06.810 things first we need to identify the
00:03:09.200 00:03:09.210 positive and the negative side of this
00:03:11.510 00:03:11.520 because you do have to observe polarity
00:03:13.040 00:03:13.050 that's very very important to this I
00:03:14.870 00:03:14.880 know on this already this is positive
00:03:18.590 00:03:18.600 this is negative they look different
00:03:21.220 00:03:21.230 there's markings on it so you may want
00:03:24.500 00:03:24.510 to make sure that you're looking for any
00:03:25.730 00:03:25.740 positive or negative markings on it
00:03:27.290 00:03:27.300 which on the XS sells is there so we
00:03:32.510 00:03:32.520 have to consider that another
00:03:34.880 00:03:34.890 consideration these were charged they've
00:03:37.790 00:03:37.800 been sitting for about 3 years maybe a
00:03:43.010 00:03:43.020 little bit more but that being said
00:03:46.900 00:03:46.910 capacitors will discharge over time when
00:03:49.490 00:03:49.500 they're sitting and they do it very
00:03:50.660 00:03:50.670 slowly but this one still has 0.6 1
00:03:58.250 00:03:58.260 volts on it now 0.6 volts doesn't sound
00:04:03.440 00:04:03.450 like much a double-a battery has 1.5
00:04:06.530 00:04:06.540 volts however these have an enormous
00:04:09.820 00:04:09.830 amount of energy being stored that can
00:04:13.340 00:04:13.350 discharge very very fast way faster than
00:04:16.070 00:04:16.080 you would double a battery
00:04:17.470 00:04:17.480 battery like that so even though this is
00:04:19.990 00:04:20.000 0.6 volts if you dead short these two
00:04:23.200 00:04:23.210 terminals or anything like that it will
00:04:25.390 00:04:25.400 spark and it might even weld things
00:04:27.670 00:04:27.680 together depending what it is so you
00:04:29.440 00:04:29.450 want to make sure that these are as
00:04:31.000 00:04:31.010 discharge as possible you might have 0.1
00:04:35.170 00:04:35.180 volts when you pull it straight out of
00:04:37.240 00:04:37.250 the box that's very common but like I
00:04:39.730 00:04:39.740 said these are 0.6 I won't be surprised
00:04:42.670 00:04:42.680 if the rest of these around 0.6 or 0.5
00:04:45.240 00:04:45.250 so we know positive we know be negative
00:04:48.420 00:04:48.430 so we're going to start this is going to
00:04:52.270 00:04:52.280 be where we're going to connect our
00:04:54.820 00:04:54.830 amplifier and power that kind of thing
00:04:56.770 00:04:56.780 into it on one end there so to wire this
00:05:00.160 00:05:00.170 in series we take another cell this
00:05:05.050 00:05:05.060 being a negative this being a positive
00:05:08.070 00:05:08.080 that will go like so we have busbars so
00:05:14.620 00:05:14.630 these are very critical and what you're
00:05:16.870 00:05:16.880 doing the more material you can have the
00:05:20.560 00:05:20.570 better up to a certain point there's
00:05:21.820 00:05:21.830 gonna be no return if this is one-inch
00:05:23.230 00:05:23.240 thick it's not gonna do anything more
00:05:25.480 00:05:25.490 than a half inch thick and these are
00:05:27.640 00:05:27.650 about an eighth inch thick these will
00:05:30.100 00:05:30.110 work pretty well a little bit thicker
00:05:31.270 00:05:31.280 wouldn't be bad depending on the
00:05:32.560 00:05:32.570 controller you got
00:05:33.900 00:05:33.910 but these do work out pretty well these
00:05:37.870 00:05:37.880 are aluminum do not use steel steel is
00:05:40.630 00:05:40.640 not as good of a conductor aluminum
00:05:43.270 00:05:43.280 works out pretty well it's fairly
00:05:44.440 00:05:44.450 economical or you can go copper copper
00:05:47.500 00:05:47.510 does work a better on caps it doesn't
00:05:49.780 00:05:49.790 seem like a whole lot when you're
00:05:51.490 00:05:51.500 comparing the same size and everything
00:05:52.690 00:05:52.700 but it does make a difference at a
00:05:55.480 00:05:55.490 higher cost so we will get these
00:06:00.220 00:06:00.230 connected we have a lock washer and the
00:06:05.890 00:06:05.900 appropriate nut and you want to make
00:06:09.040 00:06:09.050 sure that you get these torqued
00:06:11.280 00:06:11.290 appropriately not so light that it does
00:06:14.770 00:06:14.780 not hold or it'll vibrate loose and not
00:06:17.680 00:06:17.690 too much to wear strips it so on these I
00:06:23.140 00:06:23.150 go to about one or two ago chukkas and
00:06:25.090 00:06:25.100 it seems to work just fine so now that
00:06:27.940 00:06:27.950 we have two of these
00:06:30.980 00:06:30.990 these are our connection points we can
00:06:33.540 00:06:33.550 now see one point two two volts because
00:06:43.410 00:06:43.420 we put these in series so every time you
00:06:44.910 00:06:44.920 put it in series your voltage will
00:06:47.460 00:06:47.470 increase however your capacity does not
00:06:51.300 00:06:51.310 increase it actually goes down we'll get
00:06:53.640 00:06:53.650 to that as soon as we get one of these
00:06:55.350 00:06:55.360 completely assembled so now that we've
00:06:59.250 00:06:59.260 got one of these we need to add another
00:07:03.560 00:07:03.570 one positive here negative here same
00:07:11.370 00:07:11.380 thing as the other one
00:07:33.040 00:07:33.050 and now we have our negative over here
00:07:36.650 00:07:36.660 but we have a positive on the other side
00:07:39.740 00:07:39.750 so I'll show this with three cells and
00:07:43.700 00:07:43.710 we have one point two four so we didn't
00:07:48.590 00:07:48.600 gain a whole lot this cell itself was
00:07:52.280 00:07:52.290 completely discharged this cell may
00:07:55.130 00:07:55.140 actually be bad it would have to be
00:07:56.930 00:07:56.940 tested it to be inconsistent with the
00:08:00.560 00:08:00.570 rest of these showing extra voltage but
00:08:06.140 00:08:06.150 we have to recharge that to see but we
00:08:09.050 00:08:09.060 are going to continue adding two more
00:08:12.620 00:08:12.630 cells to this until we get five
00:08:30.630 00:08:30.640 so now we've got all five of these
00:08:32.830 00:08:32.840 together we've got our negative down
00:08:34.360 00:08:34.370 here our positive down here we did banks
00:08:36.909 00:08:36.919 of six both of these would come out on
00:08:38.469 00:08:38.479 top it can be a little bit easier
00:08:40.719 00:08:40.729 depending what it is that you're doing
00:08:41.969 00:08:41.979 but if we check the each cell
00:08:44.170 00:08:44.180 individually
00:08:45.190 00:08:45.200 we've got point six point six zero as we
00:08:52.090 00:08:52.100 saw before 0.46 and point two so when we
00:08:58.540 00:08:58.550 do this all in series this should a ver
00:09:00.700 00:09:00.710 Ajay
00:09:01.420 00:09:01.430 and we've got point five seven so it's
00:09:08.410 00:09:08.420 down a little bit but we've got point
00:09:11.530 00:09:11.540 five seven volts across this whole thing
00:09:14.590 00:09:14.600 now because we're using the two point
00:09:17.230 00:09:17.240 eight five when we charge this it will
00:09:20.770 00:09:20.780 charge at the voltage that you do it at
00:09:23.550 00:09:23.560 if you put it on a charger itself and
00:09:26.290 00:09:26.300 you put the charger up 12 volts it will
00:09:28.060 00:09:28.070 hold 12 volts you take it off it will
00:09:29.980 00:09:29.990 maintain that 12 volts if you have it at
00:09:32.680 00:09:32.690 fourteen point four volts in your car
00:09:34.750 00:09:34.760 when you shut the car off this will stay
00:09:36.550 00:09:36.560 at fourteen point four volts provided
00:09:39.010 00:09:39.020 there is no draw on the system so that
00:09:42.550 00:09:42.560 is one beauty of the caps is whatever
00:09:45.130 00:09:45.140 voltage it is that you're charging at or
00:09:48.010 00:09:48.020 do you store them at that's where it
00:09:50.050 00:09:50.060 natively wants to go so when you've got
00:09:51.550 00:09:51.560 a bunch of draw if you're using a
00:09:53.890 00:09:53.900 battery it's going to want to bring down
00:09:55.660 00:09:55.670 to where the battery voltages so your
00:09:58.630 00:09:58.640 alternator is depleted all of that
00:10:02.020 00:10:02.030 amperage that you're putting out can't
00:10:04.000 00:10:04.010 put out anymore you're down to say
00:10:05.860 00:10:05.870 thirteen point zero volts which is where
00:10:07.630 00:10:07.640 the batteries rest now you're really
00:10:09.670 00:10:09.680 into the battery power with capacitors
00:10:12.420 00:10:12.430 because they're wanting to rest where
00:10:15.190 00:10:15.200 you had it you don't have that draw so
00:10:18.430 00:10:18.440 the all the voltage that the alternator
00:10:20.440 00:10:20.450 was giving it is going to maintain a
00:10:22.540 00:10:22.550 higher voltage the downside of this is
00:10:24.850 00:10:24.860 you don't have the overall capacity
00:10:26.910 00:10:26.920 so from an amp hour standpoint you might
00:10:30.670 00:10:30.680 have a group thirty-one that might be a
00:10:32.320 00:10:32.330 hundred amp hours these will be nowhere
00:10:35.620 00:10:35.630 near that a hundred amp hours means you
00:10:37.450 00:10:37.460 can put 100 amps on that
00:10:40.350 00:10:40.360 battery for one hour and it will go to
00:10:43.170 00:10:43.180 ten point five volts or so that's the
00:10:45.630 00:10:45.640 complete discharge rate so we'll go from
00:10:48.269 00:10:48.279 a 13 point zero to 10 volts completely
00:10:51.420 00:10:51.430 depleted not good for the battery when
00:10:52.889 00:10:52.899 you do that but you could put a hundred
00:10:54.269 00:10:54.279 amps on it for an hour to get to that
00:10:56.519 00:10:56.529 point these won't do that these you can
00:10:59.490 00:10:59.500 put a hundred amps on it with no
00:11:02.130 00:11:02.140 charging going into it and it's only
00:11:04.079 00:11:04.089 going to last seconds it's definitely
00:11:06.780 00:11:06.790 not going to last an hour so how do we
00:11:08.910 00:11:08.920 figure out the actual capacity of this
00:11:11.160 00:11:11.170 Bank well like we looked at before these
00:11:13.860 00:11:13.870 are three thousand one hundred and fifty
00:11:16.230 00:11:16.240 farad's each with capacitors 3150 you
00:11:21.600 00:11:21.610 actually divide between the number of
00:11:23.280 00:11:23.290 cells so three thousand one hundred
00:11:25.590 00:11:25.600 fifty divided by five is six hundred and
00:11:29.130 00:11:29.140 thirty at full capacity voltage fourteen
00:11:32.370 00:11:32.380 point two volts so these will provide
00:11:34.850 00:11:34.860 630 ferret's of storage if you have less
00:11:39.240 00:11:39.250 voltage you actually have less capacity
00:11:41.040 00:11:41.050 as well so you want to get as close as
00:11:42.810 00:11:42.820 possible to maximizing the voltage when
00:11:46.620 00:11:46.630 you have two point eight five you want
00:11:47.939 00:11:47.949 to have two point eight five volts per
00:11:49.949 00:11:49.959 cell to get the most capacity out of
00:11:52.290 00:11:52.300 that as well if we had three thousand
00:11:54.689 00:11:54.699 farad cells and we had six of them that
00:11:56.970 00:11:56.980 would be a 500 farad because we're
00:11:58.889 00:11:58.899 taking three thousand divided by six
00:12:00.990 00:12:01.000 that's 500 so we have 630 farad's right
00:12:05.069 00:12:05.079 here where in the old days this would
00:12:08.189 00:12:08.199 not even be close you'd have to have 630
00:12:10.769 00:12:10.779 individual ones of these that are
00:12:13.470 00:12:13.480 slightly larger to get 630 ferret's so
00:12:17.579 00:12:17.589 where would you use these well one bank
00:12:21.090 00:12:21.100 you could use in a musical application I
00:12:24.180 00:12:24.190 like to recommend a thousand watts of
00:12:26.550 00:12:26.560 amplifier power you can go as much as
00:12:28.980 00:12:28.990 two thousand watts and still be pretty
00:12:31.230 00:12:31.240 good no I have 1 volt one and a half
00:12:32.939 00:12:32.949 volts of drop so for two thousand watts
00:12:37.350 00:12:37.360 of amp you can use this on musical setup
00:12:41.280 00:12:41.290 and you'd be in really good shape for
00:12:44.069 00:12:44.079 every two thousand Watts that you have
00:12:45.780 00:12:45.790 you have to add one more Bank of these
00:12:48.439 00:12:48.449 fortunately we have the ability to make
00:12:51.300 00:12:51.310 more banks of these so let's say this
00:12:54.120 00:12:54.130 Bank is good for 2,000 watts but we've
00:12:56.190 00:12:56.200 got a 6000 watt amplifier we've got to
00:12:59.550 00:12:59.560 make three of these banks so we're going
00:13:03.510 00:13:03.520 to repeat this same thing two more times
00:13:09.430 00:13:09.440 [Music]
00:13:56.929 00:13:56.939 so now that we've got three individual
00:13:59.939 00:13:59.949 banks assembled we need to get these
00:14:02.030 00:14:02.040 parallel and when we do this we're gonna
00:14:04.109 00:14:04.119 gain the capacity of the 630 times three
00:14:07.530 00:14:07.540 and that's going to be the entire bank
00:14:09.629 00:14:09.639 as it is in capacity at the voltage that
00:14:13.109 00:14:13.119 we put into it so because we've already
00:14:16.169 00:14:16.179 started doing individual banks that we
00:14:18.179 00:14:18.189 tie together there's two different ways
00:14:19.799 00:14:19.809 that we can do that one we could do one
00:14:21.689 00:14:21.699 bar that we have made so we have spaced
00:14:24.299 00:14:24.309 out for each individual post one giant
00:14:27.900 00:14:27.910 bar covering as many as we need in this
00:14:29.579 00:14:29.589 case it would be three so we have one
00:14:31.410 00:14:31.420 bar that goes from here to here to here
00:14:33.239 00:14:33.249 with holes and we would secure it or
00:14:36.829 00:14:36.839 because we have a bunch of these bars
00:14:39.150 00:14:39.160 already we're just going to connect one
00:14:42.329 00:14:42.339 to here another from here to here
00:15:01.740 00:15:01.750 and then on the positive side we'll do
00:15:07.060 00:15:07.070 the same thing and that's sparking
00:15:16.320 00:15:16.330 because these are going to neutralize
00:15:18.700 00:15:18.710 one of these banks is lower than the
00:15:21.400 00:15:21.410 other so that's another reason do this
00:15:23.320 00:15:23.330 well discharge we're going to put up
00:15:24.730 00:15:24.740 with a little bit of spark here
00:16:01.040 00:16:01.050 now I've got the positive side all three
00:16:03.809 00:16:03.819 connected the negative side all three
00:16:06.869 00:16:06.879 connected and we can check voltage and
00:16:11.480 00:16:11.490 we now have one point seven volts so
00:16:15.540 00:16:15.550 some of these as you saw from the
00:16:17.819 00:16:17.829 sparking we're charged little more than
00:16:20.400 00:16:20.410 the other ones so we've got one point 7
00:16:22.710 00:16:22.720 volts across all of these and this could
00:16:26.280 00:16:26.290 be connected now I said there are two
00:16:29.069 00:16:29.079 ways that we can connect all these cells
00:16:31.199 00:16:31.209 together and this is still the existing
00:16:33.090 00:16:33.100 that we've got but the other way that we
00:16:35.670 00:16:35.680 could do this is going to require a
00:16:37.650 00:16:37.660 little bit of imagination because I
00:16:38.970 00:16:38.980 don't actually have the things made to
00:16:41.249 00:16:41.259 do this but if we connect each of these
00:16:46.050 00:16:46.060 together you would have these in
00:16:51.179 00:16:51.189 parallel so picture this as a one solid
00:16:54.809 00:16:54.819 bar one bar that connects all of these
00:16:58.429 00:16:58.439 so all of this would be one giant piece
00:17:01.620 00:17:01.630 and what you're accomplishing there is
00:17:03.420 00:17:03.430 you're getting each one of these in
00:17:05.100 00:17:05.110 series but they're also in parallel so
00:17:08.699 00:17:08.709 the advantage to that would be you have
00:17:12.569 00:17:12.579 a whole lot more surface here you can
00:17:14.069 00:17:14.079 get a whole lot more current through
00:17:15.210 00:17:15.220 there you don't have to worry about that
00:17:16.470 00:17:16.480 you could use a little bit thinner
00:17:18.419 00:17:18.429 material in doing that that can make a
00:17:21.510 00:17:21.520 for very easy connections across the
00:17:24.029 00:17:24.039 board you have fewer small pieces
00:17:26.880 00:17:26.890 happening there the disadvantage to
00:17:29.490 00:17:29.500 doing that is something that I did not
00:17:31.020 00:17:31.030 talk about with doing these individual
00:17:32.940 00:17:32.950 bars which would be load balancing there
00:17:36.779 00:17:36.789 are load balancing bus bars that you can
00:17:38.490 00:17:38.500 put between these caps and what those
00:17:40.529 00:17:40.539 will do is prevent a one cell for being
00:17:43.500 00:17:43.510 overcharged so this one might be
00:17:46.770 00:17:46.780 slightly higher on charge than this one
00:17:49.500 00:17:49.510 so you continuously put voltage in this
00:17:52.440 00:17:52.450 one will stop charging this one will
00:17:55.740 00:17:55.750 take the energy that would be going to
00:17:58.020 00:17:58.030 charging this one and it will charge
00:17:59.220 00:17:59.230 this one instead so you get all of them
00:18:01.950 00:18:01.960 at equal charge which is supposed to
00:18:04.049 00:18:04.059 give a better performance overall
00:18:05.580 00:18:05.590 because you don't have
00:18:07.260 00:18:07.270 spots between here and here where you
00:18:10.050 00:18:10.060 might have some uneven balance from
00:18:13.080 00:18:13.090 current draw depending how well you've
00:18:15.420 00:18:15.430 got these parallels as well and all your
00:18:17.070 00:18:17.080 connections that can make a difference
00:18:18.890 00:18:18.900 in my experience I have not really used
00:18:22.680 00:18:22.690 load balancing I have not found a need
00:18:25.680 00:18:25.690 for it for burp applications once you
00:18:28.380 00:18:28.390 get it everything charged and it will
00:18:30.060 00:18:30.070 kind of balance itself out over time but
00:18:32.940 00:18:32.950 in a daily application you might want to
00:18:35.790 00:18:35.800 use load balancing just for your own
00:18:37.980 00:18:37.990 protection but also you can give a
00:18:40.080 00:18:40.090 little bit better performance from SPL
00:18:42.090 00:18:42.100 some might argue that load balancing
00:18:43.590 00:18:43.600 does make a difference
00:18:44.550 00:18:44.560 I personally haven't seen it myself so
00:18:47.100 00:18:47.110 now we've got our bank assembled and we
00:18:48.990 00:18:49.000 can use this and we're going to say that
00:18:51.300 00:18:51.310 we're gonna have our positive connected
00:18:52.860 00:18:52.870 here er- connected down here and this is
00:18:55.320 00:18:55.330 in the car but we haven't put power to
00:18:58.590 00:18:58.600 it because remember this is not charged
00:19:00.450 00:19:00.460 this is one point seven volts at this
00:19:02.340 00:19:02.350 point before we can have any use of this
00:19:05.610 00:19:05.620 it needs to be up at 12 13 14 volts if
00:19:09.990 00:19:10.000 you put a smart charger on this whether
00:19:12.510 00:19:12.520 you pick up a lot of times where it will
00:19:14.100 00:19:14.110 sense how much charges on it and then it
00:19:16.710 00:19:16.720 will dial that back so not manual we're
00:19:19.560 00:19:19.570 just keep charging it if you put one of
00:19:21.390 00:19:21.400 those on here it's gonna say this is a
00:19:22.920 00:19:22.930 dead battery it's probably not going to
00:19:25.290 00:19:25.300 charge it might start to do it for a few
00:19:26.760 00:19:26.770 seconds and they'll freak out won't
00:19:28.860 00:19:28.870 charge so there's two ways you can go
00:19:31.710 00:19:31.720 about this one you can put a manual
00:19:33.090 00:19:33.100 charger on it and observe the voltage
00:19:36.090 00:19:36.100 till you get up to at least maybe nine
00:19:38.520 00:19:38.530 or ten volts then you can probably put a
00:19:39.990 00:19:40.000 smart charger on it and it's going to
00:19:41.370 00:19:41.380 work the other option if you have a
00:19:43.500 00:19:43.510 charge that will do six or twelve volts
00:19:45.540 00:19:45.550 you can put six volts on this and even a
00:19:48.960 00:19:48.970 smart charger might be okay on the six
00:19:51.600 00:19:51.610 volts setting so once you get six volts
00:19:53.760 00:19:53.770 is actually going to charge up to about
00:19:54.930 00:19:54.940 eight at that point you can then put a
00:19:57.360 00:19:57.370 12 volt charger on it and I've had
00:19:58.890 00:19:58.900 success doing that where even a smart
00:20:01.200 00:20:01.210 charger you can put a 12 volt setting
00:20:04.470 00:20:04.480 after it's got eight volts or so and it
00:20:07.980 00:20:07.990 will work if you're doing manual
00:20:09.600 00:20:09.610 charging make sure you're constantly
00:20:11.610 00:20:11.620 monitoring voltage you definitely do not
00:20:14.520 00:20:14.530 want to just assume it's going to charge
00:20:15.900 00:20:15.910 so much over a certain period of time
00:20:17.340 00:20:17.350 you definitely want to watch it all the
00:20:19.500 00:20:19.510 time and make sure it does not get
00:20:21.000 00:20:21.010 to control you do not want it to go over
00:20:22.500 00:20:22.510 fourteen point four volts at any given
00:20:24.300 00:20:24.310 point so now we've got this charged up
00:20:26.670 00:20:26.680 we've got an in-car now why would you
00:20:29.250 00:20:29.260 want to use caps well an SPL competition
00:20:32.100 00:20:32.110 you need a lot of power and a very short
00:20:34.620 00:20:34.630 period of time and these can deliver
00:20:36.480 00:20:36.490 power much faster than a battery will
00:20:39.420 00:20:39.430 that has to do with internal resistance
00:20:41.580 00:20:41.590 they have very very low internal
00:20:43.050 00:20:43.060 resistance so we can deliver a ton of
00:20:45.000 00:20:45.010 power in a short period of time which is
00:20:46.440 00:20:46.450 perfect for SPL bursts where you would
00:20:50.040 00:20:50.050 not want to use this is where you need a
00:20:51.720 00:20:51.730 lot of capacity maybe you have enough
00:20:54.600 00:20:54.610 alternator power to keep up or maybe you
00:20:57.780 00:20:57.790 gonna play it with without the car
00:20:59.970 00:20:59.980 running for a period of time these do
00:21:02.130 00:21:02.140 not have that capacity you're not going
00:21:03.990 00:21:04.000 to want to use it for that purpose if
00:21:05.430 00:21:05.440 you're looking to save weight this has a
00:21:07.380 00:21:07.390 substantial weight savings over battery
00:21:09.210 00:21:09.220 a battery of this size will be probably
00:21:11.970 00:21:11.980 closer to 80 or 90 pounds where this is
00:21:14.970 00:21:14.980 gonna be closer to about 20 pounds so
00:21:16.650 00:21:16.660 you have a significant weight savings
00:21:18.240 00:21:18.250 and the difference and doing caps over
00:21:20.250 00:21:20.260 batteries because we can configure this
00:21:22.230 00:21:22.240 in any way that we want any shape form
00:21:24.690 00:21:24.700 we can turn these they don't have to go
00:21:26.400 00:21:26.410 in a straight line these two could come
00:21:28.320 00:21:28.330 over here we can rotate him orient them
00:21:30.270 00:21:30.280 however we need to you can fit these
00:21:32.010 00:21:32.020 into really peculiar places that you
00:21:34.470 00:21:34.480 couldn't fit a battery that's one static
00:21:36.210 00:21:36.220 shape these you can put any orientation
00:21:39.090 00:21:39.100 upside down sideways however you want so
00:21:42.000 00:21:42.010 whichever way works best for you you can
00:21:44.280 00:21:44.290 make this work now if you're doing solid
00:21:46.560 00:21:46.570 busbars you're kind of limited there but
00:21:48.780 00:21:48.790 from your doing individual singles we
00:21:52.290 00:21:52.300 can manipulate the shape however we need
00:21:53.850 00:21:53.860 to and whichever way you need to fit if
00:21:55.800 00:21:55.810 there's a spot that this shape that's
00:21:57.720 00:21:57.730 very narrow will will work for you you
00:22:00.480 00:22:00.490 can slide it in one spot that works out
00:22:02.310 00:22:02.320 perfect for that application remember
00:22:03.810 00:22:03.820 this is completely configurable where
00:22:05.430 00:22:05.440 you can do this so we've talked about
00:22:06.840 00:22:06.850 all the plus sides of these now the
00:22:08.430 00:22:08.440 downside is going to be cost these do
00:22:12.120 00:22:12.130 cost significantly more than an AGM
00:22:15.000 00:22:15.010 battery however it's still less than a
00:22:17.370 00:22:17.380 lithium battery so that's a
00:22:19.260 00:22:19.270 consideration when you're looking at the
00:22:21.060 00:22:21.070 weight savings and the performance gains
00:22:23.100 00:22:23.110 if you don't need the amp power capacity
00:22:26.070 00:22:26.080 then this is definitely worth spending
00:22:27.720 00:22:27.730 the extra money for something like this
00:22:29.760 00:22:29.770 now maybe you don't want to configure
00:22:31.740 00:22:31.750 all of these individually you like the
00:22:34.560 00:22:34.570 of the caps but you want in a battery
00:22:37.230 00:22:37.240 case well we offer those on EMF car
00:22:39.360 00:22:39.370 audio calm those are from excess power
00:22:41.190 00:22:41.200 they come already in the case any
00:22:43.759 00:22:43.769 battery size case that they have we can
00:22:47.039 00:22:47.049 put caps in them so we can have a group
00:22:50.009 00:22:50.019 31 that has two banks of these in there
00:22:53.580 00:22:53.590 so that's kind of like the equivalent of
00:22:55.620 00:22:55.630 having the the power delivery of two
00:22:58.440 00:22:58.450 group thirty ones but in the size of one
00:23:00.330 00:23:00.340 case so we are taking up less space for
00:23:02.129 00:23:02.139 that power delivery or even in the
00:23:04.649 00:23:04.659 smaller cases like a the 50-100 case
00:23:07.259 00:23:07.269 would have one of these in it so you can
00:23:09.629 00:23:09.639 get more power out of that same case
00:23:11.340 00:23:11.350 size those also have all the load
00:23:13.320 00:23:13.330 balancing in those so you don't have to
00:23:15.840 00:23:15.850 worry about any of that stuff and still
00:23:17.759 00:23:17.769 getting the best performance possible
00:23:18.869 00:23:18.879 out of that battery size case also with
00:23:22.019 00:23:22.029 those cases you have the benefit of
00:23:23.340 00:23:23.350 having only one positive and one
00:23:25.259 00:23:25.269 negative to deal with and you could take
00:23:26.909 00:23:26.919 out a battery that has an amp rack bus
00:23:29.399 00:23:29.409 bars or anything already built for it
00:23:30.720 00:23:30.730 and put a bunch of these caps in that
00:23:33.539 00:23:33.549 place because the case is the same if
00:23:35.369 00:23:35.379 you liked this video give it a thumbs up
00:23:37.169 00:23:37.179 if you have any questions or comments
00:23:39.119 00:23:39.129 about super caps in general or any
00:23:41.850 00:23:41.860 questions about how this is laid out you
00:23:44.220 00:23:44.230 can leave those comments below you can
