Recently I am working on old RC car that I got, as I figured out it has this motor: http://www.lrp.cc/en/product/vector-k4-brushless-motor-175t/ I am sure it is Vector 4K.
It has been running on Turnigy 5000mAh, 40-50C discharge, 2cell 7.4V lipo battery. But as I have noticed the wires that are connected directly to the motor are heating up really badly, even the wire protection is melting. Now the battery is unusable since it gone puffy. Could it be bad battery? Could it be bad cooling, since radiator thermal paste is dried out? Maybe you have some recommendations for new battery?
Thanks for help!
