Main duties:
overload protection, short circuit protection, over current protection.
Precautions:
Before installing the protection board, you must be sure that the battery is well matched, the voltage difference between each battery should not be 0.05V
the smaller the voltage difference, the better the protection board will work.
If it is the replacement of an old electronic card, please pay attention to the proper functioning of the batteries.
During installation, use a multimeter to check the battery voltage.
