2. ESC Thermal Protection: The ESC will gradually reduce the output but won’t cut it off when the ESC temperature goes above 120°C. For ensuring the motor can still get some power and won’t cause crashes, so the maximum reduction is about 60% of the full power. (Here we are describing the ESC’s reaction in soft cutoff mode, while if in hard cutoff mode; it will immediately cut off the power.)
