The problems I have with batteries in all my chops is legendary. I dunno what it is, but I go through 'em pretty fast. Don't know why that is, but it really fuckin' sucks when you're hours away from home and your stuck on the side of a road with a toasted battery.
I've done my research and I'm told this will be the last battery I will ever have to buy. I sure as hell hope so they cost a small fortune. I talked to their tech guy and he tells me for a kick only chopper this here 8 cell will work. It weighs 1.5 lbs which is kind of crazy it has all that power in such a small package.
