The DJI Intelligent Flight Battery for the DJI Mini 4K and DJI Mini 2 features a high energy density that not only lowers the overall weight but extends max flight time to 31 minutes for even more fun. With the built-in DJI Intelligent Battery Management System, battery status is monitored and reported in real-time, allowing you to focus less on battery level and more on flying. Stable energy output and accurate calculation of remaining flight time add another layer of safety during flight.
