Just wondering how many amps i should be using to charge my 4200's with? Anybody know? thx

5 amps would be a safe rate.

5amps to preserve life of the battery but if you want overall performance and dont care if you have to buy batterys every couple of months then charge at 8 amps or even higher. just watch temp of battery dont get it over 150

What charge rate do you use at home during the week and while at the races? Do u use the slow charge at home or the fast charge? Do u use the slow charge at the races or the fast charge?
