DJI Heater for Phantom 3 Intelligent Flight Battery

This Heater from DJI is used to preheat your Phantom 3 Intelligent Flight Battery in in air temperatures between -4 and 41°F. The Heater uses the flight battery's power to raise the battery temperature to an optimal operating range between 41 and 95°F, which will ensure the safety and performance of your aircraft. A 3-stage overheat protection mechanism prevents the battery from overheating. If temperatures exceed 95°F, the Heater will automatically deactivate, with additional failsafe barriers at 122°F and 208°F.
