I know that a DC will be a better charger BUT I'm not to familiar with power supplies. Also the two tracks i race at have AC outlets for everyone to use. The only reason I'm looking to keep the price bellow 150 (but i am willing to pay more) is the fact that I mainly Nitro race and that the batteries that I will be chargering are basically for "playing around" and receiver packs for my nitros. I have 3 electric cars and 4 nitros. But with the playing around comment I'm still looking for a high(er) quality charger because I may end up going electric indoor racing later (gota do SOMETHING in the winter). Can the Hyperion 0610iNet be run on AC or is it only DC? a link to them would be nice thanks again.
