HobbyWing SC8 ESC problem.

I am having an electrical issue with the ESC in my EXO Buggy. Im running a SC8 120amp ESC 4pole 2700kv motor on 4s LiPo. The problem is today when i went to go run it around the steering servo was just giving up. Seems like it was draining the battery and then shutting off. Would not work correctly on 4s or 3s LiPo (yes i checked charge). When i put in a 2s (7.4v) everything worked perfect. Is my internal BEC shot? I am going to pull a BEC off one of my scalers and see if it fixes the issue.

Sounds like you're headed the right direction.

So just for an update....
It is the internal BEC on my HobbyWing ESC. Real quickly installed a Castle BEC and everything worked perfect. Really good power to, seems to have woken the servo up a little. But anyways, guess I answered my own questions.
