I did a search and didn't find anything on this: I was busy so I hope I remembered all the symptoms accurately.
I was flying yesterday and I THINK I might have removed a battery from my Air 2 without first powering the 'copter down. I noticed a single LED remained on and I heard a 'beep' combination I've never heard before (that must have been when I put it back in). I put it back in the copter and tried to power up or down with no luck. I was in a bit of a hurry to continue, so I put another battery in, flew with no problems, and when I landed, put the first one back and then it powered down properly. I charged it back up when I got home and it seems fine. All four LEDs are on. I'll be flying later today so I'll use that battery and see, but for now it's acting normal.
I hope I got all the details correct. Does this sound like something that might happen if the battery is pulled before powering down? I'm not going to try it again just to find out
