Dear all,
I recently bought an 1:10 electric buggy, which is my first large scale rc car, and while it's being shipped, I went to a nearby hobby shop an purchased a 7.4v 2S 4000mah 30C (burst 60C) Li-Po battery. According to online information 4Ahx30C=120A. Does that mean if I am planning to upgrade the motor and esc to brushless, I have to find those specifying 120A or above? If I have a 60A brushless motor with the 120A battery will the battery cook the motor and destroy my setup? Or does it work the other way?

Many thanks,
