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:

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

Instructions：

You can install the battery directly after receiving it. The direction and polarity of the battery installation are subject to the symbols on the circuit board

After installing the battery, the direction of the notch is the same, and then screw on the copper pillar,
After the copper pillar is installed, confirm that there is no problem, you can install the cable, and you can use it after the cable is connected.

Note: If there is no protection board layer, the output terminal will have no voltage, because the protection board is connected in series in the circuit. If there is no protection board, the output is open.
