Razor mx500 (mildly modded monster)
So out of nowhere my 48v 20ah lithium ion battery pack started tripping the bms board at anything over half throttle. I swapped the motor for a different motor, still does it. I swapped speed controllers for another speed controller... still does it. Tried both new parts together, still does it! Did my battery pack **** the bed on me or something? Really confused and frustrated. Halp!
