Current: The average instantaneous maximum of each layer is 20a, and it is recommended to be less than 10a for a long time (the actual current is determined by the battery performance)
Electrical parameters and precautions:
It is best to choose the protection board when placing the order to avoid overcharge, over discharge and voltage imbalance during use.
It is best to choose our dedicated charger. If other chargers are used, you need to choose a DC connector. , It is recommended that each layer does not exceed 1a charging current
