1 Strings 3.2V Iron Phosphate Protection Board Single Section 3.7V Battery Prevent Putting Protective Board 25A16A12A

One and role

The battery protection board is mainly used to protect the battery from being damaged, extend the service life of the battery, and improve the safety performance of the battery.

2. Function

Excessive protection: When the battery charges or exceeds the rated charging voltage, the protective board will automatically disconnect and stop charging.

Passing protection: When the battery voltage is reduced to a certain value, the protective board will turn off the discharge function to prevent the battery from excessive discharge.

· Overcurrent protection: During the battery discharge process, if the current exceeds the set value, the protective board will automatically turn off the discharge to protect the battery and circuit.

· Short -circuit protection: When the battery occurs short circuit, the protective board will automatically close within a few milliseconds to prevent damage caused by short circuit.

In summary, the battery protection board effectively protects the safety of the battery through its over -charging, overdue, overcurrent and short -circuit protection functions.These functions ensure that the battery can be properly protected in various use scenarios, avoiding damage caused by improper use.
