Thanks for that advice... it would have definitely been a big mess had you not mentioned that fact. What other battery manufacturere is a sure bet? Also, should he get two 3s batteries, or the two 2s's will be fine? Is my info on the mah and C rating correct?

i assume your erevo is a 1/10th same as mine

this pic shows battery size allowable



i assume you have a mamba monster, so you can go nuts with 6s
