PCB BMS 6 Series 22V 18650 Lithium Battery Protection Board is a 6 string 22V circuit power tools mostly used for solar lighting, for dedicated 18650 battery packs. It is designed for 3.7V 18650 models lithium batteries for charging, Protection from overcharge and over-discharge.

Battery protection board, as the name suggests battery protection board is mainly rechargeable (Refers to the lithium battery) and protects the integrated circuit board.

Lithium battery (rechargeable type) so need protection, is determined by its own characteristics.

As the lithium battery, its material determines itself can not be overcharge, over-discharge, overcurrent, short circuit, and ultra-high temperature charge and discharge, so lithium battery lithium components will always follow A protective plate with sampling resistor, and a current fuse.
