Incessant battery overheating

The battery cell will show overheating at 60 degrees. It must be stationary in a cool place for at least 2-3 hours before returning to a safe working temperature.

Batteries cannot be charged in low temperatures.

The battery has a self-heating function. At sub-zero temperatures, the battery pack will heat up to above-zero temperatures. However, for improved charging and discharging performance, place the battery indoors. After enabling the battery's self-heating function, the temperature will rise to the optimal level, and each discharge cycle will consume 10% of the electricity.
