The DJI FPV Fly More Kit is a battery kit for your FPV drone. This pack includes 2 official DJI FPV Intelligent Flight Batteries and the DJI FPV Battery Charging Hub. An advanced technology accurately tracks the battery status and warns you when it reaches the minimum battery capacity required to fly back. You can use these batteries if your current battery is broken or runs out while you're flying. With the DJI FPV Battery Charging Hub, you can charge 3 FPV Intelligent Flight Batteries at the same time. All your batteries are fully charged in about 2 hours and 45 minutes. Thanks to the LED indicator, you can see at a glance when the batteries are fully charged. The battery that's least empty gets charged first. That way, you'll have a fully charged battery as soon as possible. You can fly your FPV drone for up to 20 minutes on a fully charged battery.
