The DJI TB50 Intelligent Flight Battery is a replacement battery for your Inspire 2 quadcopter and is also compatible with the Ronin 2 gimbal. Like the battery that came with your Inspire 2, this is a 4280mAh, lithium-ion polymer (LiPo) battery that yields between 25 and 27 minutes of flight time, depending on conditions and which Zenmuse system you use.
In addition to enhanced flight time, the Intelligent Flight Battery uses a built-in 70W self-heating system capable of heating itself to 41°F every minute. This self-heating function can be enabled either automatically or manually. The management unit constantly monitors battery status, making all information, including battery level and battery temperature, easily visible in the DJI GO app.
