Have had my P2V+ for a couple months now. For the 2nd time now, I have been flying and about halfway through the battery pack, and I get the low battery warning sound from the phone, and the lights on the bottom of the P2V+ turn red. Then as I start to bring it back, it goes away and back to normal... lasts about 10 or 15 seconds. Has anyone else experienced something like this... thoughts, ideas, suggestions? So far it hasn't caused any problems, but I would hate for it to keep getting worse and cause something more serious down the road.
