Feigao 7L, Warrior 9920 + 12 GP 3300 cells = hot?

If the batteries shorted, it would send this energy into the controller, which would be problematic for sure. A shorted motor could also spell trouble for the controller(will cuase excessive current and heat which may overheat and damage the controller before it has a chance to thermal). Loss of receiver signal shouldn't damage the controller(it simply stops working after the hard braking effect until it picks up the signal again).
