Anyone with cap bank install?

so say I bought an AGM battery with the big 3 upgrade on a 120 amp or bigger alternator would I be able to buy 2 supercapacitors like the ones @banginhummer posted

would that work on a 2k RMS system?

This is the simplest kind. Those boxes are resistors, and the symbols below are capacitors.

Essentially all it is, is each capacitor has it's own bleeder resistor wired to it. Idea is that A. capacitors of a higher voltage will bleed drain slightly faster than the ones with a lower voltage. Bringing them together. And B. will bleed off power faster than the capacitor's own leakage rate.

To calculate what resistance you need, take the leakage current of your capacitor listed on the manufacturer's website, multiply it by 10, then use ohm's law of ohms=volts/amps. Where volts is what you expect each capacitor to be charged to, and amps is the leakage current multiplied by 10.

You'll want to use good resistors for this. You can get 1% tolerance ones from Mouser. The typical 10% tolerance resistors you get from radioshack don't quite cut it

you have a balancing circuit on yours? if so what values did you use? and is that the circuit diagram exactly?

they handle the amperage well?

Personally I'd spend the extra couple bucks and get these

but do you think that's enough for 2k? if I did spend the extra $$ on those?

I have 50 ohm 10 watt resistors on mine. They only need to dissipate a couple milliwatts of heat

They should work really well for 2k IMO

so for each cap you have 1 50 ohm 10 watt resistor 1% tolerance in parallel with it? and it goes across the cap positive to negative?

any of these? and do you have any other balancing circuitry? or is that it?
