What sort of battery do you need for this kind of work?
It's centered around very high discharge ability. One advantageous consequence of that is fast charging ability too, but that's not a big practical consideration for us, because we have about two hours to turn the car around between competition runs, and we'll only need a few minutes to charge up if we need to push it. We'll have plenty of time to maintain and check over the rest of the car as we essentially trickle charge the thing back up.
I'd like to see the inners of that setup.
