How to Use: 1. When the balance indicator light is on, the balance work is on. 2. When the balance indicator light is off, the balance circuit is dormant. 3. When the balance indicator light is flashing, power failure or circuit failure. Specification: Item Type: Battery Active Equalizer Applicable Battery: NCM(Li ion) or LFP, not suitable for LTO. Single Cell Voltage: 3.0-4.2V Recommended Battery Capacity: Below 30AH Voltage Balance Accuracy: 30mV between adjacent voltages (typ.) Equalization Method: It is detected that the voltage difference between adjacent batteries is greater than 0.1V to trigger the equalization start, and the voltage difference between adjacent batteries is less than 0.03V to stop working Balance Current: 0.1V voltage difference 0.5A balance current, when the voltage difference is above 0.2V, the maximum balance current is 1.2A Under Voltage Protection Sleep Voltage: The adjacent voltage difference is less than 0.03V, enter the sleep state Quiescent Operating Current: 0.01mA Package List: 1 x Battery Active Equalizer 1 x Cable Note: 1. It is not recommended to be compatible with low strings, the indicator light will flash and report an error. Be sure to check that each cell is properly wired and insulated before connecting the balancing board. Otherwise will short circuit and burn the board. 2. If the battery is connected, it must be used with the BMS protection board. The and discharge voltage difference triggers the balance board to work to achieve energy transfer balance.
