I just ordered one of these the other day.. I have read quite a bit so far. From what I have read, best place for the battery is on edge on the left side on the flood chamber. Also read there is around 37 mm of space. Enough for a 2200.. is anyone running larger? If so what width / brand and mAh. Pictures would be good.

Anyone thinking of buying a mini eco, Jim at mini cat racing is very helpful and will answer your questions.
