RE: Hobbykings Turnigy battery DX8 problem
This happened? "features a built in voltage protection circuit, this circuit will automatically cutoff once the pack drops to 2.85v per cell ensuring the battery will not be damaged if you accidentally leave your transmitter switched on"
It would be my first guess. It's probably inaccurate. I don;t think I'd have any protection in a TX battery because I'd rather lose a battery than a plane.
