I just purchased an E-Power kit, and I'm waiting on it to come in. It comes with 2 14650 1050mah 3.7v rechargeable batteries. A person on the New Members forums sent me to a site that has 14650 1600mah batteries that he says he uses in his E-power without any problems and charges on the same charger that came with his kit. Does this sound right? I thought mah and size were closely related.
