well that helps a lot. Ive been looking for 3s batteries but didnt buy since i didnt know if it would fry it for not. that basic info of 3s being 11.2v or whatever gave me the answers i had left. Ill be sticking with 2s 5000+ mah and 30c. But when im looking at so 30c units it has on there that some do like a 40c burst or such so Idon't know if thats safe or not. Ifigure it is since it says a constant 30c and a burst of 40c+. But if that 40c or whatever is even just a 2 second burst it might do damage in just that few seconds. Dont think ill ever get it at full speed or throttle especially if i upgrade the lipos i assume. But we know what assuming does!! Thanks everyone for you constant help and info!! Greatly appreciated.
