Abstract. The results of using the infrared thermography method for studying the discharging process in lithium polymer batteries have been presented in this article. The general rules of discharging a lithium polymer battery are shown in the maximum mode of drone engine operation, namely, regardless of the external temperature, the process of heating the battery has a nonlinear character with a clear maximum temperature. In the course of operation of unmanned aerial vehicles under reduced temperatures, special attention is required before making a decision to connect an additional battery and fulfilling the “home” command. Testing the battery temperature during a flight with an autonomous control system can be carried out not by a thermographic camera, but by means of temperature sensors.

Keywords: infrared thermography, lithium polymer battery, dron supply, autonomous flight control.
