uhh wat charger r u using?

cause if it is one of those charger without an automatic cut off charging, it is gonna damage ur batteries.

if it is one of those that cut off automatically when u hit peak charge, than by all mean charge them at nite, i even charge mine the day before. as for the power lose, until u can handle the car pretty well, u would not notice the tiny different between a fresh charge one that has been charge a day before. cause i have been racing for more than 2 years now and i still cant tell the different.
