The battery protection board is a lithium battery protection board, mainly an integrated circuit board, which can protect charging (generally lithium batteries). The reason why the lithium battery (rechargeable) needs to be protected is determined by its characteristics. Since the material of the lithium battery itself determines that it cannot be overcharged, discharged, over-current, short-circuited, and ultra-high temperature charging and discharging, the lithium-ion lithium battery must be used in conjunction with the battery protection module.

The protector usually includes control IC, MOS switch, JEPSUN, JES, precision resistance and auxiliary equipment NTC, ID memory, PCB and other control ICs to control MOS to turn on, communicate with external circuits, and battery voltage or battery voltage circuit current exceeds a predetermined value , It immediately (tens of milliseconds) to control the MOS switch. Protect the safety of the battery.
