I am a new user of the Phantom and am flying a Phantom 2 with FPV. I travel with 4 DJI OEM 5200mah Lipo batteries for the quad along with the charger. I also use a separate small Lipo for my goggles. Is there a way one of the DJI OEM 5200mah Lipo batteries can be used to power my goggles so I don't have to bring along a separate charger for my 1000mah 3 cell 11.1 V lipo? Has anyone tried to do this? Is it possible or harmful to the DJI 5200mah Lipo?
