Bump4life Posted November 20, 2013 Report Posted November 20, 2013 I have an ~850 farad cap bank. You know how with voltage drop it's kind of all or nothing? Either you are holding 14v+ (or whatever your alt charges at) or you drop to 13v or lower. Capacitors store energy. Not in the same way batteries do though. Batteries create energy though a chemical reaction - of which only takes place below the batteries "resting voltage". Capacitors store a difference in electrons - think like static electricity. This means they can absorb/release power at ANY voltage. So in between your alternator's charging voltage and your battery's voltage potential (13v and below) - this is where caps shine. They basically act like a giant stabilizer. It cushions your drops, absorbs your peaks. I have a video of them which I'll post below. Been meaning to get a second one with the VM-1 that is just impressive results. 2 banks on how much power? a cross fire 8k? lol Buyer/Seller Feedback Thread: http://www.stevemead...5015-bump4life/ MB C220 153 Trunk Car Build Log: http://www.stevemead...d/#entry1840136 MB C280 Ipad Dash SQ Build Log: http://www.stevemeadedesigns.com/board/topic/194484-bump4lifes-new-benz-tony-c-relay-kit-pictures-ce-electric-audison-front-stage-installed/ My SPL Log: http://www.stevemead...__fromsearch__1 BMW M340 xDrive Stock, for now.

Like you said @bump4life, higher voltage, equals higher capacity yes but caps charge and discharge at a linear rate. so it doesnt matter what voltage they are used at. results should be same in a perfect world at any voltage as long as draw is the same Linear..? http://hyperphysics.phy-astr.gsu.edu/hbase/electric/capchg.html Charging current asymptotically goes to zero as it charges. Then it exponentially discharges. Energy stored in a cap = 0.5 * C * V^2 Since voltage is squared, energy skyrockets as you increase voltage.

Desousa93 Posted November 21, 2013 Report Posted November 21, 2013 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?
