Kinetik Power Cells. thats it. I run a 600 Farad Kinetik and it costs just around $100 (about 3 years ago new) and its freakin awesome. About the size of a motorcycle battery and i can run my truck off of it for a few hours without a recharge if need be. We actually put it in a buddys Z28 after he blew a battery up and he drove it about 50 some miles home on my power cell
In the pic is there 1600 Farad model
