The module contains the FPC busbar connected to the pole, and the external terminal is Hirose ZG05L2-16P-1.8H type connector

module pin definition

Module high voltage interface

The M6 embedded nut is preset at the high-voltage interface of the block, and the connecting wire between the main electrode conductive row and the module is fixed by the embedded nut to realize the high-voltage connection between the module and the outside.

How to use the lithium battery module

1. The charging current must not exceed the maximum allowable charging current specified. Charging with a current higher than the recommended value may cause problems with the battery's charge and discharge performance, mechanical performance, and safety performance, and may cause heat generation or liquid leakage.

2. The charging voltage must not exceed the absolute charging voltage specified. When the battery voltage is higher than the absolute charging voltage value, it may cause problems of the battery's charge and discharge performance, mechanical performance and safety performance, and may cause heat generation or liquid leakage.

3. The battery must be charged within the absolute charging temperature: 0 ~ 50 .

4. Connect the positive and negative poles of the battery correctly, and reverse charging is strictly prohibited. If the positive and negative poles of the battery are reversed, the battery will be scrapped and there will be potential safety hazards.
