This morning I flew a 12 minute waypoint mission with a fully charged battery and controller.
I got 'signal lost', but was not unduly worried as this often happens. But a couple of minutes later, with the signal still lost, the controller started beeping at about 2 beeps a second. This was a bit worrying, as I had no idea why it was doing this. But then I got a low battery warning, the battery icon showed red with two red bars and '0%'. Even though I knew I'd charged the battery, and remembered checking it on takeoff and seeing that it had about 98%, I was still really scared. I thought I'd never see the quadcopter again. But finally I got the signal back, and the battery indicator said 55% when I landed it - about what I'd expect.
So I wonder what was going on here? If the bird couldn't signal to the controller, how could the controller switch to '0% battery' while the bird still wasn't signalling to it? And what were those beeps? As I said, the controller was fully charged as well as the quadcopter.
