00:00:00.030 welcome to another tech stuff Tuesday 00:00:02.21000:00:02.220 this week we're gonna talk about super 00:00:04.16000:00:04.170 capacitors when you would use them why 00:00:06.55900:00:06.569 you should use them when you shouldn't 00:00:08.21000:00:08.220 use them how you assemble a bank of them 00:00:10.94000:00:10.950 we're going to go over all that stuff 00:00:12.47000:00:12.480 and have a little bit of explanation of 00:00:14.93000:00:14.940 all these applications what we've got 00:00:17.90000:00:17.910 here is definitely an excess power 00:00:20.42000:00:20.430 supercell from EMF car audio comm this 00:00:24.59000:00:24.600 particular example is two point eight 00:00:26.48000:00:26.490 five volts there are other versions of 00:00:29.63000:00:29.640 capacitors and one thing you can look at 00:00:32.60000:00:32.610 with them even the same between the same 00:00:34.49000:00:34.500 make is they may have a different 00:00:36.41000:00:36.420 voltage you might be two point seven or 00:00:37.91000:00:37.920 two point six two point five and we'll 00:00:40.04000:00:40.050 get into why that matters and then we 00:00:41.69000:00:41.700 have the capacity is three thousand one 00:00:43.61000:00:43.620 hundred and fifty farad's out of this 00:00:46.54900:00:46.559 one capacitor years ago in the past you 00:00:49.13000:00:49.140 may have had somebody say I have a 00:00:50.33000:00:50.340 capacitor and it might have been a one 00:00:52.22000:00:52.230 farad and it'll been a little bit larger 00:00:54.65000:00:54.660 than this around the same diameter maybe 00:00:57.17000:00:57.180 a little bit larger and just a little 00:00:58.79000:00:58.800 bit taller and it was one farad and it 00:01:01.54900:01:01.559 was intended to be used on a twelve volt 00:01:03.34900:01:03.359 system now those are essentially 00:01:06.53000:01:06.540 worthless in car audio if you have a 00:01:08.92900:01:08.939 high current draw those can actually 00:01:11.03000:01:11.040 cause a loss of power the amp this gets 00:01:13.58000:01:13.590 completely depleted and then you end up 00:01:16.28000:01:16.290 having a low voltage scenario it's 00:01:18.35000:01:18.360 trying to level out where your source 00:01:19.64000:01:19.650 coming in is and this is a buffer it 00:01:22.70000:01:22.710 completely depletes this so you have low 00:01:25.49000:01:25.500 voltage on this end where the amplifier 00:01:27.14000:01:27.150 might be but on this own the charging 00:01:29.53900:01:29.549 side where you might have lights and 00:01:32.35900:01:32.369 that kind of thing where all of a sudden 00:01:33.89000:01:33.900 this is not dimming as badly giving you 00:01:35.56900:01:35.579 the impression you're actually doing 00:01:37.60900:01:37.619 something but in reality you have lower 00:01:39.89000:01:39.900 power at the amp which is not affecting 00:01:41.87000:01:41.880 performance at all so we don't really 00:01:44.45000:01:44.460 see those too often anymore we don't use 00:01:46.63900:01:46.649 them anymore they generally don't work 00:01:48.67900:01:48.689 sometimes they be 2 farad same kind of 00:01:50.92900:01:50.939 thing and if you actually check the 00:01:52.58000:01:52.590 peasants of those old ones I might find 00:01:54.92000:01:54.930 that that are labeled 1 farad actually 00:01:58.39900:01:58.409 has something else in the canister and 00:01:59.95900:01:59.969 it was not actually one farad at all it 00:02:02.63000:02:02.640 may have been much much much less and 00:02:04.60900:02:04.619 those go with the cheap things you get 00:02:06.64900:02:06.659 we pay for that kind of thing so we 00:02:09.80000:02:09.810 don't use those this is 00:02:11.12000:02:11.130 the newer technology with the super 00:02:14.33000:02:14.340 capacitors so on these like I said it's 00:02:18.86000:02:18.870 2.8 5 volts and but we need it to 00:02:21.77000:02:21.780 operate on a 12 volt system and a 12 00:02:24.59000:02:24.600 volt system you're going to charge 00:02:25.70000:02:25.710 around 14 point 4 volts so what we're 00:02:28.76000:02:28.770 gonna do is we need enough of these 00:02:31.78000:02:31.790 wired in series to be a usable level so 00:02:36.68000:02:36.690 we're going to use five of these and if 00:02:38.87000:02:38.880 you do the math on that you're gonna 00:02:41.12000:02:41.130 come just under 14 point 4 volts now 00:02:43.79000:02:43.800 that's fine because there actually is a 00:02:47.12000:02:47.130 little bit of a tolerance in these I 00:02:49.49000:02:49.500 believe it's 10% that you can safely go 00:02:51.74000:02:51.750 over people have said that you can go 00:02:54.62000:02:54.630 over that I don't recommend that but 00:02:56.51000:02:56.520 going to 14 point 4 volts with a 2.8 5 00:03:00.80000:03:00.810 volt capacitor with 5 of them in series 00:03:03.50000:03:03.510 you can do safely just fine so first 00:03:06.80000:03:06.810 things first we need to identify the 00:03:09.20000:03:09.210 positive and the negative side of this 00:03:11.51000:03:11.520 because you do have to observe polarity 00:03:13.04000:03:13.050 that's very very important to this I 00:03:14.87000:03:14.880 know on this already this is positive 00:03:18.59000:03:18.600 this is negative they look different 00:03:21.22000:03:21.230 there's markings on it so you may want 00:03:24.50000:03:24.510 to make sure that you're looking for any 00:03:25.73000:03:25.740 positive or negative markings on it 00:03:27.29000:03:27.300 which on the XS sells is there so we 00:03:32.51000:03:32.520 have to consider that another 00:03:34.88000:03:34.890 consideration these were charged they've 00:03:37.79000:03:37.800 been sitting for about 3 years maybe a 00:03:43.01000:03:43.020 little bit more but that being said 00:03:46.90000:03:46.910 capacitors will discharge over time when 00:03:49.49000:03:49.500 they're sitting and they do it very 00:03:50.66000:03:50.670 slowly but this one still has 0.6 1 00:03:58.25000:03:58.260 volts on it now 0.6 volts doesn't sound 00:04:03.44000:04:03.450 like much a double-a battery has 1.5 00:04:06.53000:04:06.540 volts however these have an enormous 00:04:09.82000:04:09.830 amount of energy being stored that can 00:04:13.34000:04:13.350 discharge very very fast way faster than 00:04:16.07000:04:16.080 you would double a battery 00:04:17.47000:04:17.480 battery like that so even though this is 00:04:19.99000:04:20.000 0.6 volts if you dead short these two 00:04:23.20000:04:23.210 terminals or anything like that it will 00:04:25.39000:04:25.400 spark and it might even weld things 00:04:27.67000:04:27.680 together depending what it is so you 00:04:29.44000:04:29.450 want to make sure that these are as 00:04:31.00000:04:31.010 discharge as possible you might have 0.1 00:04:35.17000:04:35.180 volts when you pull it straight out of 00:04:37.24000:04:37.250 the box that's very common but like I 00:04:39.73000:04:39.740 said these are 0.6 I won't be surprised 00:04:42.67000:04:42.680 if the rest of these around 0.6 or 0.5 00:04:45.24000:04:45.250 so we know positive we know be negative 00:04:48.42000:04:48.430 so we're going to start this is going to 00:04:52.27000:04:52.280 be where we're going to connect our 00:04:54.82000:04:54.830 amplifier and power that kind of thing 00:04:56.77000:04:56.780 into it on one end there so to wire this 00:05:00.16000:05:00.170 in series we take another cell this 00:05:05.05000:05:05.060 being a negative this being a positive 00:05:08.07000:05:08.080 that will go like so we have busbars so 00:05:14.62000:05:14.630 these are very critical and what you're 00:05:16.87000:05:16.880 doing the more material you can have the 00:05:20.56000:05:20.570 better up to a certain point there's 00:05:21.82000:05:21.830 gonna be no return if this is one-inch 00:05:23.23000:05:23.240 thick it's not gonna do anything more 00:05:25.48000:05:25.490 than a half inch thick and these are 00:05:27.64000:05:27.650 about an eighth inch thick these will 00:05:30.10000:05:30.110 work pretty well a little bit thicker 00:05:31.27000:05:31.280 wouldn't be bad depending on the 00:05:32.56000:05:32.570 controller you got 00:05:33.90000:05:33.910 but these do work out pretty well these 00:05:37.87000:05:37.880 are aluminum do not use steel steel is 00:05:40.63000:05:40.640 not as good of a conductor aluminum 00:05:43.27000:05:43.280 works out pretty well it's fairly 00:05:44.44000:05:44.450 economical or you can go copper copper 00:05:47.50000:05:47.510 does work a better on caps it doesn't 00:05:49.78000:05:49.790 seem like a whole lot when you're 00:05:51.49000:05:51.500 comparing the same size and everything 00:05:52.69000:05:52.700 but it does make a difference at a 00:05:55.48000:05:55.490 higher cost so we will get these 00:06:00.22000:06:00.230 connected we have a lock washer and the 00:06:05.89000:06:05.900 appropriate nut and you want to make 00:06:09.04000:06:09.050 sure that you get these torqued 00:06:11.28000:06:11.290 appropriately not so light that it does 00:06:14.77000:06:14.780 not hold or it'll vibrate loose and not 00:06:17.68000:06:17.690 too much to wear strips it so on these I 00:06:23.14000:06:23.150 go to about one or two ago chukkas and 00:06:25.09000:06:25.100 it seems to work just fine so now that 00:06:27.94000:06:27.950 we have two of these 00:06:30.98000:06:30.990 these are our connection points we can 00:06:33.54000:06:33.550 now see one point two two volts because 00:06:43.41000:06:43.420 we put these in series so every time you 00:06:44.91000:06:44.920 put it in series your voltage will 00:06:47.46000:06:47.470 increase however your capacity does not 00:06:51.30000:06:51.310 increase it actually goes down we'll get 00:06:53.64000:06:53.650 to that as soon as we get one of these 00:06:55.35000:06:55.360 completely assembled so now that we've 00:06:59.25000:06:59.260 got one of these we need to add another 00:07:03.56000:07:03.570 one positive here negative here same 00:07:11.37000:07:11.380 thing as the other one 00:07:33.04000:07:33.050 and now we have our negative over here 00:07:36.65000:07:36.660 but we have a positive on the other side 00:07:39.74000:07:39.750 so I'll show this with three cells and 00:07:43.70000:07:43.710 we have one point two four so we didn't 00:07:48.59000:07:48.600 gain a whole lot this cell itself was 00:07:52.28000:07:52.290 completely discharged this cell may 00:07:55.13000:07:55.140 actually be bad it would have to be 00:07:56.93000:07:56.940 tested it to be inconsistent with the 00:08:00.56000:08:00.570 rest of these showing extra voltage but 00:08:06.14000:08:06.150 we have to recharge that to see but we 00:08:09.05000:08:09.060 are going to continue adding two more 00:08:12.62000:08:12.630 cells to this until we get five 00:08:30.63000:08:30.640 so now we've got all five of these 00:08:32.83000:08:32.840 together we've got our negative down 00:08:34.36000:08:34.370 here our positive down here we did banks 00:08:36.90900:08:36.919 of six both of these would come out on 00:08:38.46900:08:38.479 top it can be a little bit easier 00:08:40.71900:08:40.729 depending what it is that you're doing 00:08:41.96900:08:41.979 but if we check the each cell 00:08:44.17000:08:44.180 individually 00:08:45.19000:08:45.200 we've got point six point six zero as we 00:08:52.09000:08:52.100 saw before 0.46 and point two so when we 00:08:58.54000:08:58.550 do this all in series this should a ver 00:09:00.70000:09:00.710 Ajay 00:09:01.42000:09:01.430 and we've got point five seven so it's 00:09:08.41000:09:08.420 down a little bit but we've got point 00:09:11.53000:09:11.540 five seven volts across this whole thing 00:09:14.59000:09:14.600 now because we're using the two point 00:09:17.23000:09:17.240 eight five when we charge this it will 00:09:20.77000:09:20.780 charge at the voltage that you do it at 00:09:23.55000:09:23.560 if you put it on a charger itself and 00:09:26.29000:09:26.300 you put the charger up 12 volts it will 00:09:28.06000:09:28.070 hold 12 volts you take it off it will 00:09:29.98000:09:29.990 maintain that 12 volts if you have it at 00:09:32.68000:09:32.690 fourteen point four volts in your car 00:09:34.75000:09:34.760 when you shut the car off this will stay 00:09:36.55000:09:36.560 at fourteen point four volts provided 00:09:39.01000:09:39.020 there is no draw on the system so that 00:09:42.55000:09:42.560 is one beauty of the caps is whatever 00:09:45.13000:09:45.140 voltage it is that you're charging at or 00:09:48.01000:09:48.020 do you store them at that's where it 00:09:50.05000:09:50.060 natively wants to go so when you've got 00:09:51.55000:09:51.560 a bunch of draw if you're using a 00:09:53.89000:09:53.900 battery it's going to want to bring down 00:09:55.66000:09:55.670 to where the battery voltages so your 00:09:58.63000:09:58.640 alternator is depleted all of that 00:10:02.02000:10:02.030 amperage that you're putting out can't 00:10:04.00000:10:04.010 put out anymore you're down to say 00:10:05.86000:10:05.870 thirteen point zero volts which is where 00:10:07.63000:10:07.640 the batteries rest now you're really 00:10:09.67000:10:09.680 into the battery power with capacitors 00:10:12.42000:10:12.430 because they're wanting to rest where 00:10:15.19000:10:15.200 you had it you don't have that draw so 00:10:18.43000:10:18.440 the all the voltage that the alternator 00:10:20.44000:10:20.450 was giving it is going to maintain a 00:10:22.54000:10:22.550 higher voltage the downside of this is 00:10:24.85000:10:24.860 you don't have the overall capacity 00:10:26.91000:10:26.920 so from an amp hour standpoint you might 00:10:30.67000:10:30.680 have a group thirty-one that might be a 00:10:32.32000:10:32.330 hundred amp hours these will be nowhere 00:10:35.62000:10:35.630 near that a hundred amp hours means you 00:10:37.45000:10:37.460 can put 100 amps on that 00:10:40.35000:10:40.360 battery for one hour and it will go to 00:10:43.17000:10:43.180 ten point five volts or so that's the 00:10:45.63000:10:45.640 complete discharge rate so we'll go from 00:10:48.26900:10:48.279 a 13 point zero to 10 volts completely 00:10:51.42000:10:51.430 depleted not good for the battery when 00:10:52.88900:10:52.899 you do that but you could put a hundred 00:10:54.26900:10:54.279 amps on it for an hour to get to that 00:10:56.51900:10:56.529 point these won't do that these you can 00:10:59.49000:10:59.500 put a hundred amps on it with no 00:11:02.13000:11:02.140 charging going into it and it's only 00:11:04.07900:11:04.089 going to last seconds it's definitely 00:11:06.78000:11:06.790 not going to last an hour so how do we 00:11:08.91000:11:08.920 figure out the actual capacity of this 00:11:11.16000:11:11.170 Bank well like we looked at before these 00:11:13.86000:11:13.870 are three thousand one hundred and fifty 00:11:16.23000:11:16.240 farad's each with capacitors 3150 you 00:11:21.60000:11:21.610 actually divide between the number of 00:11:23.28000:11:23.290 cells so three thousand one hundred 00:11:25.59000:11:25.600 fifty divided by five is six hundred and 00:11:29.13000:11:29.140 thirty at full capacity voltage fourteen 00:11:32.37000:11:32.380 point two volts so these will provide 00:11:34.85000:11:34.860 630 ferret's of storage if you have less 00:11:39.24000:11:39.250 voltage you actually have less capacity 00:11:41.04000:11:41.050 as well so you want to get as close as 00:11:42.81000:11:42.820 possible to maximizing the voltage when 00:11:46.62000:11:46.630 you have two point eight five you want 00:11:47.93900:11:47.949 to have two point eight five volts per 00:11:49.94900:11:49.959 cell to get the most capacity out of 00:11:52.29000:11:52.300 that as well if we had three thousand 00:11:54.68900:11:54.699 farad cells and we had six of them that 00:11:56.97000:11:56.980 would be a 500 farad because we're 00:11:58.88900:11:58.899 taking three thousand divided by six 00:12:00.99000:12:01.000 that's 500 so we have 630 farad's right 00:12:05.06900:12:05.079 here where in the old days this would 00:12:08.18900:12:08.199 not even be close you'd have to have 630 00:12:10.76900:12:10.779 individual ones of these that are 00:12:13.47000:12:13.480 slightly larger to get 630 ferret's so 00:12:17.57900:12:17.589 where would you use these well one bank 00:12:21.09000:12:21.100 you could use in a musical application I 00:12:24.18000:12:24.190 like to recommend a thousand watts of 00:12:26.55000:12:26.560 amplifier power you can go as much as 00:12:28.98000:12:28.990 two thousand watts and still be pretty 00:12:31.23000:12:31.240 good no I have 1 volt one and a half 00:12:32.93900:12:32.949 volts of drop so for two thousand watts 00:12:37.35000:12:37.360 of amp you can use this on musical setup 00:12:41.28000:12:41.290 and you'd be in really good shape for 00:12:44.06900:12:44.079 every two thousand Watts that you have 00:12:45.78000:12:45.790 you have to add one more Bank of these 00:12:48.43900:12:48.449 fortunately we have the ability to make 00:12:51.30000:12:51.310 more banks of these so let's say this 00:12:54.12000:12:54.130 Bank is good for 2,000 watts but we've 00:12:56.19000:12:56.200 got a 6000 watt amplifier we've got to 00:12:59.55000:12:59.560 make three of these banks so we're going 00:13:03.51000:13:03.520 to repeat this same thing two more times 00:13:09.43000:13:09.440 [Music] 00:13:56.92900:13:56.939 so now that we've got three individual 00:13:59.93900:13:59.949 banks assembled we need to get these 00:14:02.03000:14:02.040 parallel and when we do this we're gonna 00:14:04.10900:14:04.119 gain the capacity of the 630 times three 00:14:07.53000:14:07.540 and that's going to be the entire bank 00:14:09.62900:14:09.639 as it is in capacity at the voltage that 00:14:13.10900:14:13.119 we put into it so because we've already 00:14:16.16900:14:16.179 started doing individual banks that we 00:14:18.17900:14:18.189 tie together there's two different ways 00:14:19.79900:14:19.809 that we can do that one we could do one 00:14:21.68900:14:21.699 bar that we have made so we have spaced 00:14:24.29900:14:24.309 out for each individual post one giant 00:14:27.90000:14:27.910 bar covering as many as we need in this 00:14:29.57900:14:29.589 case it would be three so we have one 00:14:31.41000:14:31.420 bar that goes from here to here to here 00:14:33.23900:14:33.249 with holes and we would secure it or 00:14:36.82900:14:36.839 because we have a bunch of these bars 00:14:39.15000:14:39.160 already we're just going to connect one 00:14:42.32900:14:42.339 to here another from here to here 00:15:01.74000:15:01.750 and then on the positive side we'll do 00:15:07.06000:15:07.070 the same thing and that's sparking 00:15:16.32000:15:16.330 because these are going to neutralize 00:15:18.70000:15:18.710 one of these banks is lower than the 00:15:21.40000:15:21.410 other so that's another reason do this 00:15:23.32000:15:23.330 well discharge we're going to put up 00:15:24.73000:15:24.740 with a little bit of spark here 00:16:01.04000:16:01.050 now I've got the positive side all three 00:16:03.80900:16:03.819 connected the negative side all three 00:16:06.86900:16:06.879 connected and we can check voltage and 00:16:11.48000:16:11.490 we now have one point seven volts so 00:16:15.54000:16:15.550 some of these as you saw from the 00:16:17.81900:16:17.829 sparking we're charged little more than 00:16:20.40000:16:20.410 the other ones so we've got one point 7 00:16:22.71000:16:22.720 volts across all of these and this could 00:16:26.28000:16:26.290 be connected now I said there are two 00:16:29.06900:16:29.079 ways that we can connect all these cells 00:16:31.19900:16:31.209 together and this is still the existing 00:16:33.09000:16:33.100 that we've got but the other way that we 00:16:35.67000:16:35.680 could do this is going to require a 00:16:37.65000:16:37.660 little bit of imagination because I 00:16:38.97000:16:38.980 don't actually have the things made to 00:16:41.24900:16:41.259 do this but if we connect each of these 00:16:46.05000:16:46.060 together you would have these in 00:16:51.17900:16:51.189 parallel so picture this as a one solid 00:16:54.80900:16:54.819 bar one bar that connects all of these 00:16:58.42900:16:58.439 so all of this would be one giant piece 00:17:01.62000:17:01.630 and what you're accomplishing there is 00:17:03.42000:17:03.430 you're getting each one of these in 00:17:05.10000:17:05.110 series but they're also in parallel so 00:17:08.69900:17:08.709 the advantage to that would be you have 00:17:12.56900:17:12.579 a whole lot more surface here you can 00:17:14.06900:17:14.079 get a whole lot more current through 00:17:15.21000:17:15.220 there you don't have to worry about that 00:17:16.47000:17:16.480 you could use a little bit thinner 00:17:18.41900:17:18.429 material in doing that that can make a 00:17:21.51000:17:21.520 for very easy connections across the 00:17:24.02900:17:24.039 board you have fewer small pieces 00:17:26.88000:17:26.890 happening there the disadvantage to 00:17:29.49000:17:29.500 doing that is something that I did not 00:17:31.02000:17:31.030 talk about with doing these individual 00:17:32.94000:17:32.950 bars which would be load balancing there 00:17:36.77900:17:36.789 are load balancing bus bars that you can 00:17:38.49000:17:38.500 put between these caps and what those 00:17:40.52900:17:40.539 will do is prevent a one cell for being 00:17:43.50000:17:43.510 overcharged so this one might be 00:17:46.77000:17:46.780 slightly higher on charge than this one 00:17:49.50000:17:49.510 so you continuously put voltage in this 00:17:52.44000:17:52.450 one will stop charging this one will 00:17:55.74000:17:55.750 take the energy that would be going to 00:17:58.02000:17:58.030 charging this one and it will charge 00:17:59.22000:17:59.230 this one instead so you get all of them 00:18:01.95000:18:01.960 at equal charge which is supposed to 00:18:04.04900:18:04.059 give a better performance overall 00:18:05.58000:18:05.590 because you don't have 00:18:07.26000:18:07.270 spots between here and here where you 00:18:10.05000:18:10.060 might have some uneven balance from 00:18:13.08000:18:13.090 current draw depending how well you've 00:18:15.42000:18:15.430 got these parallels as well and all your 00:18:17.07000:18:17.080 connections that can make a difference 00:18:18.89000:18:18.900 in my experience I have not really used 00:18:22.68000:18:22.690 load balancing I have not found a need 00:18:25.68000:18:25.690 for it for burp applications once you 00:18:28.38000:18:28.390 get it everything charged and it will 00:18:30.06000:18:30.070 kind of balance itself out over time but 00:18:32.94000:18:32.950 in a daily application you might want to 00:18:35.79000:18:35.800 use load balancing just for your own 00:18:37.98000:18:37.990 protection but also you can give a 00:18:40.08000:18:40.090 little bit better performance from SPL 00:18:42.09000:18:42.100 some might argue that load balancing 00:18:43.59000:18:43.600 does make a difference 00:18:44.55000:18:44.560 I personally haven't seen it myself so 00:18:47.10000:18:47.110 now we've got our bank assembled and we 00:18:48.99000:18:49.000 can use this and we're going to say that 00:18:51.30000:18:51.310 we're gonna have our positive connected 00:18:52.86000:18:52.870 here er- connected down here and this is 00:18:55.32000:18:55.330 in the car but we haven't put power to 00:18:58.59000:18:58.600 it because remember this is not charged 00:19:00.45000:19:00.460 this is one point seven volts at this 00:19:02.34000:19:02.350 point before we can have any use of this 00:19:05.61000:19:05.620 it needs to be up at 12 13 14 volts if 00:19:09.99000:19:10.000 you put a smart charger on this whether 00:19:12.51000:19:12.520 you pick up a lot of times where it will 00:19:14.10000:19:14.110 sense how much charges on it and then it 00:19:16.71000:19:16.720 will dial that back so not manual we're 00:19:19.56000:19:19.570 just keep charging it if you put one of 00:19:21.39000:19:21.400 those on here it's gonna say this is a 00:19:22.92000:19:22.930 dead battery it's probably not going to 00:19:25.29000:19:25.300 charge it might start to do it for a few 00:19:26.76000:19:26.770 seconds and they'll freak out won't 00:19:28.86000:19:28.870 charge so there's two ways you can go 00:19:31.71000:19:31.720 about this one you can put a manual 00:19:33.09000:19:33.100 charger on it and observe the voltage 00:19:36.09000:19:36.100 till you get up to at least maybe nine 00:19:38.52000:19:38.530 or ten volts then you can probably put a 00:19:39.99000:19:40.000 smart charger on it and it's going to 00:19:41.37000:19:41.380 work the other option if you have a 00:19:43.50000:19:43.510 charge that will do six or twelve volts 00:19:45.54000:19:45.550 you can put six volts on this and even a 00:19:48.96000:19:48.970 smart charger might be okay on the six 00:19:51.60000:19:51.610 volts setting so once you get six volts 00:19:53.76000:19:53.770 is actually going to charge up to about 00:19:54.93000:19:54.940 eight at that point you can then put a 00:19:57.36000:19:57.370 12 volt charger on it and I've had 00:19:58.89000:19:58.900 success doing that where even a smart 00:20:01.20000:20:01.210 charger you can put a 12 volt setting 00:20:04.47000:20:04.480 after it's got eight volts or so and it 00:20:07.98000:20:07.990 will work if you're doing manual 00:20:09.60000:20:09.610 charging make sure you're constantly 00:20:11.61000:20:11.620 monitoring voltage you definitely do not 00:20:14.52000:20:14.530 want to just assume it's going to charge 00:20:15.90000:20:15.910 so much over a certain period of time 00:20:17.34000:20:17.350 you definitely want to watch it all the 00:20:19.50000:20:19.510 time and make sure it does not get 00:20:21.00000:20:21.010 to control you do not want it to go over 00:20:22.50000:20:22.510 fourteen point four volts at any given 00:20:24.30000:20:24.310 point so now we've got this charged up 00:20:26.67000:20:26.680 we've got an in-car now why would you 00:20:29.25000:20:29.260 want to use caps well an SPL competition 00:20:32.10000:20:32.110 you need a lot of power and a very short 00:20:34.62000:20:34.630 period of time and these can deliver 00:20:36.48000:20:36.490 power much faster than a battery will 00:20:39.42000:20:39.430 that has to do with internal resistance 00:20:41.58000:20:41.590 they have very very low internal 00:20:43.05000:20:43.060 resistance so we can deliver a ton of 00:20:45.00000:20:45.010 power in a short period of time which is 00:20:46.44000:20:46.450 perfect for SPL bursts where you would 00:20:50.04000:20:50.050 not want to use this is where you need a 00:20:51.72000:20:51.730 lot of capacity maybe you have enough 00:20:54.60000:20:54.610 alternator power to keep up or maybe you 00:20:57.78000:20:57.790 gonna play it with without the car 00:20:59.97000:20:59.980 running for a period of time these do 00:21:02.13000:21:02.140 not have that capacity you're not going 00:21:03.99000:21:04.000 to want to use it for that purpose if 00:21:05.43000:21:05.440 you're looking to save weight this has a 00:21:07.38000:21:07.390 substantial weight savings over battery 00:21:09.21000:21:09.220 a battery of this size will be probably 00:21:11.97000:21:11.980 closer to 80 or 90 pounds where this is 00:21:14.97000:21:14.980 gonna be closer to about 20 pounds so 00:21:16.65000:21:16.660 you have a significant weight savings 00:21:18.24000:21:18.250 and the difference and doing caps over 00:21:20.25000:21:20.260 batteries because we can configure this 00:21:22.23000:21:22.240 in any way that we want any shape form 00:21:24.69000:21:24.700 we can turn these they don't have to go 00:21:26.40000:21:26.410 in a straight line these two could come 00:21:28.32000:21:28.330 over here we can rotate him orient them 00:21:30.27000:21:30.280 however we need to you can fit these 00:21:32.01000:21:32.020 into really peculiar places that you 00:21:34.47000:21:34.480 couldn't fit a battery that's one static 00:21:36.21000:21:36.220 shape these you can put any orientation 00:21:39.09000:21:39.100 upside down sideways however you want so 00:21:42.00000:21:42.010 whichever way works best for you you can 00:21:44.28000:21:44.290 make this work now if you're doing solid 00:21:46.56000:21:46.570 busbars you're kind of limited there but 00:21:48.78000:21:48.790 from your doing individual singles we 00:21:52.29000:21:52.300 can manipulate the shape however we need 00:21:53.85000:21:53.860 to and whichever way you need to fit if 00:21:55.80000:21:55.810 there's a spot that this shape that's 00:21:57.72000:21:57.730 very narrow will will work for you you 00:22:00.48000:22:00.490 can slide it in one spot that works out 00:22:02.31000:22:02.320 perfect for that application remember 00:22:03.81000:22:03.820 this is completely configurable where 00:22:05.43000:22:05.440 you can do this so we've talked about 00:22:06.84000:22:06.850 all the plus sides of these now the 00:22:08.43000:22:08.440 downside is going to be cost these do 00:22:12.12000:22:12.130 cost significantly more than an AGM 00:22:15.00000:22:15.010 battery however it's still less than a 00:22:17.37000:22:17.380 lithium battery so that's a 00:22:19.26000:22:19.270 consideration when you're looking at the 00:22:21.06000:22:21.070 weight savings and the performance gains 00:22:23.10000:22:23.110 if you don't need the amp power capacity 00:22:26.07000:22:26.080 then this is definitely worth spending 00:22:27.72000:22:27.730 the extra money for something like this 00:22:29.76000:22:29.770 now maybe you don't want to configure 00:22:31.74000:22:31.750 all of these individually you like the 00:22:34.56000:22:34.570 of the caps but you want in a battery 00:22:37.23000:22:37.240 case well we offer those on EMF car 00:22:39.36000:22:39.370 audio calm those are from excess power 00:22:41.19000:22:41.200 they come already in the case any 00:22:43.75900:22:43.769 battery size case that they have we can 00:22:47.03900:22:47.049 put caps in them so we can have a group 00:22:50.00900:22:50.019 31 that has two banks of these in there 00:22:53.58000:22:53.590 so that's kind of like the equivalent of 00:22:55.62000:22:55.630 having the the power delivery of two 00:22:58.44000:22:58.450 group thirty ones but in the size of one 00:23:00.33000:23:00.340 case so we are taking up less space for 00:23:02.12900:23:02.139 that power delivery or even in the 00:23:04.64900:23:04.659 smaller cases like a the 50-100 case 00:23:07.25900:23:07.269 would have one of these in it so you can 00:23:09.62900:23:09.639 get more power out of that same case 00:23:11.34000:23:11.350 size those also have all the load 00:23:13.32000:23:13.330 balancing in those so you don't have to 00:23:15.84000:23:15.850 worry about any of that stuff and still 00:23:17.75900:23:17.769 getting the best performance possible 00:23:18.86900:23:18.879 out of that battery size case also with 00:23:22.01900:23:22.029 those cases you have the benefit of 00:23:23.34000:23:23.350 having only one positive and one 00:23:25.25900:23:25.269 negative to deal with and you could take 00:23:26.90900:23:26.919 out a battery that has an amp rack bus 00:23:29.39900:23:29.409 bars or anything already built for it 00:23:30.72000:23:30.730 and put a bunch of these caps in that 00:23:33.53900:23:33.549 place because the case is the same if 00:23:35.36900:23:35.379 you liked this video give it a thumbs up 00:23:37.16900:23:37.179 if you have any questions or comments 00:23:39.11900:23:39.129 about super caps in general or any 00:23:41.85000:23:41.860 questions about how this is laid out you
