The BMS 2S 8A Li-ion Battery Protection Board is a protection circuit board for 2-series lithium-ion battery packs (2S), meaning a total nominal voltage of 7.4 V and a maximum charging voltage of 8.4 V.

It supports discharge current up to 8 A, providing protection against overcharge, over-discharge, overvoltage, and short circuit, ensuring safety and longevity of the cells.

The board includes balancing function for automatic voltage equalization between the two cells, improving the overall performance of the pack.

Ideal for DIY 18650 battery packs, portable power systems, power banks, audio devices, or robotic applications where a stable and reliable power supply is required.
