The usual supercap used is the Maxwell 3000F 2.7V.
6 are required in series to be able to function in a 14V vehicle environment.
The 3000F Maxwells are rated each at about 200A of max continuous current draw.
Current in series is the same so a bank of 6 are still restricted to that ~200A (max continuous). 1900A peak.
So to be safe, you'd want at least one bank for every 200A of current your system consumes.
If you have an amp which draws 1000A, then 1000/200=5 banks would give you a very safe buffer.
More banks will naturally give you more energy capacity.
It's difficult to do an apples-apples comparison of batteries to caps as they are very different creatures.
Batteries store TONS of energy while caps can store and release current very quickly.
It also depends on what you use them for....burping or demoing.
If in doubt..........just get 32 banks (192 caps) like AMI has....
thank you for saying this. i see people asking if adding 1 bank would help their 6k system. well sure it will help, but you are gunna be taxing that bank to the max aka, drawing more than 200 amps, thus reduce life and possibly causing a hazard.
anyways, these caps should be interesting, and i highly doubt these are made in the USA. if they are, and are reasonably price they may have something. I hope they do have something here, protection circuits could be nice. i wonder if passive or active. also a waiver to use? lol. tuned in to see this play out.
