Precautions for installing lithium battery protection board

With the development of the electrical appliance industry, batteries have become a must-have for people's lives, and a good battery immediately has a lithium battery protection board. Therefore, it is urgent for us to understand some common sense of lithium battery protection board. No matter which manufacturer’s protection board, the wires that need to be connected are nothing more than B- (battery connection), P- (discharge negative electrode), C- (charge negative electrode), and a large number of cables, the following markings may be slightly different For example, some manufacturers charge the negative electrode as CH-, and discharge it as D-, etc. In fact, these are batteries, the first two letters of the English word for charging, as long as everyone pays attention to it. Closer to home, today, the people of the country will share with you the precautions for installing the lithium battery protection board. The order of the protection board wiring should be:

1. Know the order of several B- P- C-, and the wiring, especially to understand where the first one is connected.

2. Solder the B- P- C- wire in advance, don't wait for the connection to be connected, because the position is not good for welding.

3. At the time of series and parallel connection, the cable is connected as expected.

4. Confirm that the cable is as expected at 100% (confirm the voltage and the sequence is OK under the multimeter).

5. Insert the cable into the protection board, and measure the voltage of P+ (battery positive electrode) and B- P+ and P- P+ and C- to see if they are the same. Normally, they should be the same.

6. Glue and reinforce the sockets to avoid loosening, and fix the protective plate (the protective plate and the battery should not be directly attached to the battery, otherwise the heat transfer will be balanced).
