The DJI Phantom 2 Vision Battery Charger is a charger for the DJI Phantom 2 Quadcopter's 11.1V, 5200mAh slot-in lithium-polymer battery. This charger only requires a single DC power connection between itself and the battery. Power regulation is handled within the battery eliminating the need for a separate balance lead. For this reason, this charger should not be used with other RC aircraft batteries.
