The Ghost battery ensures a longer flight time and reduces recharge frequency. It is shock-proof and humidity resistant. This powerful Lithium Polymer (LiPo) battery with a 4500 mAh capacity and 14.8 Volts is specifically built for Ghost Drone 2.0 and Ghost Drone 2.0 Aerial. While easily interchangable it is much lighter and more carefully built than batteries of the same size.
