Battery pack will stop work to protect itself when the temperature is out of the operation range. The
optimum operating temperature range is from 15°C to 35°C, Frequent exposure to the harsh
temperatures may worsen the performance of the battery pack and cycle life.
3. Electrical Characteristics & Test Condition
Testing Conditions: Ambient Temperature: 25±5
℃
, Humidity: 45%~75%.
Normal charge: Charge battery under CC (0.2C)/CV (56.0V) mode until over charge protection or
reduce the charge current to 0.05C, and then rest for 1h.
