I purchased my Phantom 2 Vision+ in April of 2015. The Remote control and Wi-Fi extender seemed to have a much longer battery life than the drone. Today, however, the RC was charged and the large LED was green before the flight. It lasted about 8 minutes and the RC was beeping and the large LED was flashing before the flight finished. The RC was connected to power until the LED was green and another short ~8-10 minute flight was made. The RC again started beeping and flashing. Both flight completed successfully. The RC is "sealed". There is no battery door on this model. Does anyone know the charging life cycle of these batteries? Second problem: When the Phantom is connected via USB to my computer and the Vision Assistant program is started, it does not "see" the Phantom.. The RC assistant works fine on the RC, so I concluded connections, cables, etc. were okay and the problem lay with the Phantom. Does anyone know if this is fixable locally, or is it problem that requires a factory repair station? Thanks to any and all.
