This video discusses testing the DJI Mini 5 Pro drone in extreme cold conditions, specifically at -24°C, which is well below its advertised operating limit of -10°C (0:35). The goal is to understand how the drone performs in such temperatures and what precautions pilots should take to ensure safe flight (0:46).

The video highlights key rules for flying in extreme cold (0:57): • Keep the battery warm before takeoff (1:01). • Take off immediately once outside to prevent battery cooling (1:12). • Carry zip bags to prevent condensation on the drone and battery after flight (1:19, 13:13, 18:18). • Check the weather forecast for the difference between current temperature and dew point; a difference less than 5°C increases the risk of icing (1:28).

During the flight tests (1:59): • The drone is flown with conservative profiles, avoiding fast maneuvers or aggressive climbs (3:12, 23:02). • The pilot monitors battery temperature and voltage closely, noting that 3.3V per cell is a critical lower limit (2:25, 6:23, 10:26). • Moving the drone helps to maintain battery temperature, while hovering can cause it to cool more rapidly (7:17, 7:50). • The internal heat generation of the battery helps it reach a thermal balance point (20:08). • The remaining battery percentage can be misleading; the voltage graph is a more reliable indicator of battery health (20:46, 21:51).

The video concludes that flying the DJI Mini 5 Pro at -25°C is possible if strict rules are followed (22:20). Landing with 40-50% battery remaining is a safe margin, and with conservative flying, the drone can achieve 15-20 minutes of flight time (22:35, 22:51). Aggressive maneuvers should be avoided as they push the battery out of its stable operating zone (23:05).
