I've had a Phantom 3 4k drone since late May, 2016. I use it regularly and have sent it on hundreds of flights. I've been having weird problems with the rechargeable battery you can't replace inside the drone's remote controller. The first instance happened in July 2016. I had fully charged the controller overnight and than packed it in the standard DJI backpack. I checked the charge with the controller's power button and then turned it off before packing it. When I arrived at a location I wanted to film about 12 hours later, I took out the controller and its battery was completely dead. I've never been able to figure out how the controller's battery discharged in this instance after being packed in the backpack, and I took it on many other flights afterwards without a problem, but this same thing happened again a few weeks ago. I packed the fully charged controller only to arrive at a location the next day and find its battery dead. I can only guess that something might have turned on the controller inside the backpack after it was packed, but there's no obvious culprit for that. Has anyone else had this problem with the controller in the DJI backpack?
As of today, I'm having a worse problem with charging the controller's battery. I've been trying to charge it for a whole day, but it won't charge past displaying 1.5 of the 4 lights that indicate a full charge. I've unplugged and reinserted the charging cable multiple times, and it looks like it is charging normally at first, but it stops charging after an hour and the lights never show a full charge. How can I fix this? Do they sell replacement controllers or controller batteries anywhere?
