4S LifePo4 Blue 30A 14.8V Lithium Battery Protection Board with Balanced 4S 12.8V LiFePO4 Battery Protection Board

Application: Vacuum cleaner massager battery pack LED backup power supply 12.8V li-ion electronics solar power led, ect The protection board can not be used for lithium iron phosphate battery, hernia lamp, hand drill battery pack, can not be used for electric fish machine battery pack, electric bicycle battery pack, children\’s car battery, 550 (4A) motor, 1W fish eye LED light. LFP cell has 3.2V nominal working voltage and shall be cut-off power at 3.6-3.8V per cell during charging .Lithium Iron Phosphate (LiFePO4, LFE) is kind of Li-Ion rechargeable battery for high power applications, such as EV car , Power Tool and RC hobby. LiFePO4 cells feature with high discharging current, non explosive, long cycle life, but its energy density is lower than normal Li-Ion cell (Li-Co) (higher NiMH cell) Charging voltage: 3.6V * 4 = 14.4V ( this item is for BMS 4S and 3.2V rated voltage each cell) Package 1 x 4S 30A BMS 14.8V 12.8V 18650 lithium battery Protection Board
