1.This protection board is 4s in common use lithium battery protection board (you can adjust for how many strings to be used) x`
2.Specified chip, stable performance, support disconnection protection, over-current protection, over discharge protection, overcharge protection, with balance, etc.
3.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.
4.Can use for LMO. Ternary lithium battery. LCO(3.7V)battery packs etc.
