14.4V 100A 4S BMS LiFePO4 LiFe Battery Protection Circuit Board

Description

• This protection board is 3s 4s 5s in common use LifePo battery protection board (you can adjust for how many strings to be used), the default delivery is 4S ternary lithium.
• Specified chip, stable performance, support disconnection protection, over-current protection, over discharge protection, overcharge protection, with balance, etc.
• Common use for “same port” and “different port”, the protection board uses 15 high-power of ultra-low resistance MOS tube (discharge of 8, charging of 7), in the same port mode can support the discharge current 60A, charging current 60A; different port mode discharge current 80A, charging current 60A.
• Can use for Life Po battery, battery packs etc.
