Battery protection board, as the name suggests battery protection board is mainly rechargeable (Refers to the lithium battery) and protects the integrated circuit board. As the lithium battery, its material determines itself cannot be overcharge, over-discharge, short circuit, ultra-high temperature charge, etc. So lithium battery lithium components will always follow A protective plate with a sampling resistor, and a current fuse.

Providing all the above features this 3S BMS board can combine 3 x 18650 battery to form a battery pack to provide up to 15V DC output at 20A current which can be used for heavy applications.
