I'm a new owner of a Phantom 4 Pro + and have only flown it 4 times. It gets cold in MT so flew it yesterday at 12*F with freshly charged battery for the drone and controller. Everything worked fine for the first 10 minutes or so and then when I received a low battery warning it wouldn't respond to the controls on the controller. I was able to get it down to within reach, grabbed one of the bars, and shut it down. Suggestions??
