i have a real car battery hooked up in my pit box connected to a fast charger and i use 150Ah batts so i charge one whilst runnin the other. the hole set up cost £32 for the charger and £9 per batterie and i got the car batterie for free and i already had a charger for one. i know the batts arent the hump style but i use a zip tie to hold it on to my chassis (like a savage chassis) and if i run my car for an hour a day it lasts me way over a week so i dont really need a fast charger but it looks cool in my box hehe.
