Battery protection board, as the name suggests, is mainly for rechargeable lithium batteries. It protects the integrated circuit board from overcharge, over-discharge, overcurrent, short circuit, and ultra-high temperature charge and discharge. The lithium components always follow a protective plate with a sampling resistor and a current fuse. This 4S BMS board can combine 4 x 18650 batteries to form a battery pack providing up to 15V DC output at 15A current, suitable for heavy applications.
Package Includes: 1 x 4S 15A 18650 Lithium Battery Protection Board
