[QUOTE="SounDrive, post: 8092437, member: 653833"] You need at least 6 of them to support a 14.8v system for a car and they're $60 each new (so $360 new for a single bank) - they're rated for 2.7v each. But you can buy them used (1 year on electric busses) on eBay for $220 for 12 of them which is enough for two banks, and they'll still last you a few years. So they're about the price of a good AGM battery for something that will prevent voltage drop much better Look up "ultra capacitors" or "super capacitors" on youtube and there's a few videos of people starting their cars with them and other things like that.
