Why do lithium battery packs need protective plates.

Many friends may find that when using lithium battery packs, some lithium batteries are labeled with protective plates, while others do not have protective plates. So today, let's talk about why we need to install protective panels, right?

Group protection board? A protective board is a circuit board that serves as a packaging component and is mainly composed of electronic circuits. Accurately observe the voltage of the battery and the current of the charging circuit in an environment of -40 to 85, and timely control the flow rate of the current circuit.

The protection board of the lithium battery pack protects the lithium battery and has four major functions: overcharge, overlap, overcurrent, and reverse connection protection.

Adding a protective plate to the battery is for user safety. Lithium battery packs have their own safety discharge and charging, as well as overcurrent restrictions. Adding a protective plate is to ensure that the use of lithium battery packs does not exceed the safe range. Choose a charger with overcharge protection for charging lithium batteries. If it doesn't have a board, it will remain when using a charger without overcharge protection. Just like a person who is full and you keep making them eat, only to end up being stretched out, the same goes for lithium batteries. The function of adding a protective board is to stop charging after being fully charged.
