hello i am new to this and am looking for advice. i bought a boat on ebay that i am told is a dolphin. it has a L36/56 7.2 18v aquacraft brushless motor and a 60 amp esc i dont know what kind of battery to buy for best performance without burning anything up. i am not sure if this motor is original to boat or if it has been modified. i bought a skylipo 5000 mah 11.1 v, but none of the connecters are right. i dont know if this battery will work in this boat. any advice would be greatly appreciated
