Well I flew the questionable battery for between 10 and 15 minutes when it suddenly went into auto land mode. It was discharging normally until it reached 50%. Then, it went to one light blinking on the Batt with red lights blinking on the phantom as it was attempting to land on it's on. I recharged the Batt and it seemed to charge...but too fast. Checking in the Assist software it again shows the cells as before.
Either one cell is bad or the circuit that balances them is bad. Regardless, it's likely toast for all practical purposes.
The good news is the Phantom is working like before. I have a new camera on the way and by the end of this week should be back together. Oh, and I need to order a new battery.
I need to stop watching these extreme videos on youtube etc. It's a flying camera, NOT a stunt machine.
