Ninebot ES3 - Turns off after 10 Seconds
 

Picked up 2 used ES3's today. Thought both of them worked great however, one is turning off after about 10 seconds. The only warning it gives is a quick beep and then it loses power. The app still registers it as on and will track the speed etc.

UPDATE: Now the unit won't power on but the app still shows it as online and working. Thoughts on how to fix?
