Hey guys! Just got a new a new set of tires for my maverick r/c buggy, it has been driving around for some time now, its waterproof and I have tested it after a while I charged up a 7.4 lipo (which went puffy) the motor stuttered and then stopped, steering is fine. Realised a puffy battery is bad so lol. but I don't think it's the cause, please help me fix this. THANKS BOIS.
