Feature:1. Auxiliary plate: The expansion plate is only an auxiliary BMS protection plate, without overvoltage and over-discharge protection function. Any bad battery test can be used. Voltage protection can only be achieved if it is used in parallel with the BMS protection board 2. Alignment method: it has been detected that the voltage difference between adjacent batteries is greater than 0,1V to start the equalization, and the voltage difference is less than 0,03V to stop working. (Achieving a better balanced effect requires recharging and discharging. ) 3. Suitable battery: Lithium battery equalizer module is suitable for MCN LFP, the recommended battery capacity is from 60 to 300AH, and the voltage is from 2,2V to 4,5V 4. Note: compatibility with low strings is not recommended, the indicator light will flash and report an error. Before connecting, check that each battery is properly wired and insulated. Otherwise, it will short-circuit and burn the plate 5. Voltage and current: 30mV (typical value) voltage balance accuracy between adjacent voltages, voltage difference 0.1V balance current 0.5A, when the voltage difference is above 0.2V, the maximum balance current is 1.2A. 0,01mA resting current, enter sleep state when the adjacent voltage difference is less than 0,03V .
