2, 3, 4 strings 1.3A lithium battery active balance board (with working indicator light): Scope of application: ternary lithium battery, iron lithium battery, all universal Product size: 22*16*4mm(2 strings), 22*30.5*4mm(3 strings), 22*45*4mm(4 strings) Product weight: 1.8g(2S), 3.4g(3S), 5.1g(4S) Operating voltage range: 3.0V ~ 4.5V Balanced start condition: the voltage difference between two adjacent batteries is greater than 0.1V Balance current: 1.3A (balance current is related to voltage difference, the smaller the voltage difference, the smaller the balance current)
Indicator light description:? The indicator light is on to indicate that the corresponding two batteries are being balanced. The indicator light is off, it means that the equalization has been completed, or the pressure difference has not reached the starting conditions, The flashing indicator light indicates that the equalization has failed to start (see Note 3).
Note 1: Start wiring from 0V in order. 0V is the total negative pole of the battery pack.?Do not connect the wrong wire, it will burn the chip. Note 2: Use copper wire above 0.5 square millimeter (18AWG) for connection,?the thicker the cable, the better, and the shorter the better. Note 3: The flashing indicator light indicates that the equalization has failed to start, please check whether the connecting wire is well welded,If the wire welding is correct and the indicator light still flashes, it means that the internal resistance of the battery is too large. Failed to start, please reduce the equalizing current to use (remove all R1 on the circuit board,the resistance and R2 resistance are interchanged, and the equalizing current drops to 0.5A).?
Package included:
1 x 2/3/4S BMS Battery Protection Board
