"Description:

This protection board is 3s 4s in common use lithium battery protection board
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-lowresistance MOS tube (discharge of 8, charging of 7), in the same port mode can support the dischargecurrent 60A, charging current 60A; different port mode discharge current 80A, charging current 60A.
3S Can use for LMO、Ternary lithium battery、LCO（3.7V） battery packs etc.
4S Can use for Lithium iron phosphate battery.
