Features 1、HIGH ACCURACY BALANCE: Balance voltage accuracy within 30mv, bring high accuracy energy transmission balance, exclusive balance IC 2、PROTECTION BOARD AUXILIARY: The balance board is not a BMS protection board, but an auxiliary of the protection board, so no matter how bad the battery test you use, it can be used, but there is no overvoltage or overdischarge protection function 3、SMALLER VOLTAGE DIFFERENCE: Built in improved ultra low internal resistance MOS, the balance current is 0‑1.2A, and the battery voltage difference is smaller 4、LOW STATIC POWER CONSUMPTION: Battery active equalizer possess smaller current, the static power consumption does not exceed 20uA, with balance instructions 5、1.2A CURRENT: Inductive energy transmission equalization board has 1.2A equalization current, slightly lower accuracy 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
