The DJI FPV Battery Charging Hub is a vital piece of kit that allows you to charge up to three FPV Intelligent Flight Batteries unattended. This makes it ideal for on-location shooting - but does require the DJI FPV Battery Charger (sold separately). The battery charger draws power from an available plug socket/AC outlet, which then allows the Battery Charging Hub to work. The batteries are charged in sequence, meaning that the battery with the most amount of power is prioritised. By doing so, it allows for a more efficient workflow and extended flight time. A full single battery recharge will take around 55 minutes, with a clear status LED providing essential charging information.
