4S 50A BMS Board/ 55A 3.7V Lithium battery protection board/3.2V iron phosphate/LiFePO4 battery BMS board with Balance

Description

·         Charging Current: 50A

·         Balance Current: 55mA

·         Discharge Overcurrent Protection: 70A

·         Charge Low Temperature Protection: -7℃

·         Short circuit Protection
• The lithium battery protection board uses a highly integrated intelligent lithium battery protection board integrated chip, the performance is better than the protective board composed of discrete chips.
• Can complete 4 string polymer lithium battery, ternary lithium battery, lithium iron phosphate, lithium cobalt oxide, lithium manganese oxide battery charge and discharge protection, over current, short circuit, over temperature protection and equalization function.
• It adopts 4 milliohm ultra-low internal resistance MOS tube, which has low internal resistance and high efficiency.
• It is suitable for battery pack applications in different fields such as inverters, DC motors, power tools, and solar street lights.
• It is common to the same mouth and mouth, and has strong applicability. The protection board has a heat sink and a supply line.
