What Is A Battery Protection Board?

Battery protection board, as the name implies, lithium battery protection board is mainly an integrated circuit board that protects rechargeable (generally refers to lithium battery). The reason why the lithium battery (rechargeable) needs protection is determined by its own characteristics. Since the material of the lithium battery itself determines that it cannot be overcharged, overdischarged, overcurrent, short-circuited and ultra-high temperature charged and discharged, the lithium battery component of the lithium battery will always appear with a protection board with a sampling resistor and a current fuse.
