LiFePO4 4S 12V100A Common port with Balance+UART BMS




4s 12v 100a lifepo4 battery bms 4s 12v 100a lifepo4 battery bms

Product Summary


1. Professional high current wiring design & workmanship, thus can withstand the shock of high current
2. Using fully enclosed heat-dissipating glue and a double-sided heat dissipation design, heat is dissipated in time, and the heat dissipation effect is better than others.
3. Dustproof, shockproof, anti-squeezing, and other protective functions
4. Complete overcharge, over-discharge, over current, short circuit, and equalization functions
