Features High Accuracy: The balance voltage accuracy of the battery equalizer is within 30mV, the high accuracy energy transmission is flat and horizontal, and the exclusive balance IC. Intelligent Balancing of Battery: The battery balancer uses voltage acquisition by the controller to determine the difference between the battery cells and the battery cells that need to be balanced, which can effectively reduce the difference between th Clear Running Status: When the indicator light is on, it means the balance work is on, when the indicator light is off, it means the balance circuit is dormant, and the flashing indicator light means power failure or circuit failure. Ultra Low Internal Resistance: The battery balancer has built in improved ultra low internal resistance MOS, and the balance current capability is 0A to 1.2A. Automatic Hibernate Function: When the voltage difference between two adjacent battery cells is less than 0.03V, the voltage balancer automatically enters the hibernate state. Specification: Item Type: Battery Equalizer Material: ABS Applicable Battery: NCM(Li ion) , 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 Balancer 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 it will short circuit and burn the board 2. If the battery is connected, it must be used with the BMS protection board. The charge and discharge voltage difference triggers the balance board to work to achieve energy transfer balance Package List 1 x Battery Balancer 1 x Cable
