Precautions:
Before installing the protection board, you must make sure the battery is well matched, the voltage difference between each battery should not be 0.05V
The lower the voltage difference, the better the protection board will work.
If this is a replacement for an old electronic card, please pay attention to the proper functioning of the batteries.
During installation, use a multimeter to check the battery voltage.
