HOLY $#@! !!!!!!!!!!!

Once I think about it, the voltage of a 12v battery is right around the peak charge voltage for A123's.... that is awesome!

That can't be good for them charging like that though... I know A123 systems uses a 'pulse' charge to charge them in 5 mins, which will reduce heat. Not that they will get hot.

EDIT: Wait, that's a 3s pack? I would have thought they would use a 4s pack... the voltage doesn't make any sense, a 12v battery is higher than 12v... it would be 14.5 volts at those amps.
