Feature:1. HIGH ACCURACY BALANCE: Balance voltage accuracy within 30mv, provides high accuracy energy transfer balance, exclusive balance IC2. PROTECTION BOARD AUXILIARY FUNCTION: The balance board is not a BMS protection board, but an auxiliary for the protection board, so no matter how bad the battery test you use is, it can be used, but there is no overvoltage or overdischarge protection function3. SMALLER VOLTAGE DIFFERENCE: Built in improved ultra low internal resistance MOS, the balance current is 0‑1.2A, and the battery voltage difference is smaller4. LOW STATIC POWER CONSUMPTION: Battery active equalizer has less current, the static power consumption does not exceed 20uA, with balance instructions5. 1.2A CURRENT: Inductive energy transfer equalization board has 1.2A equalization current, slightly lower accuracySpecification:Item Type: Battery Active EqualizerApplicable Battery: NCM(Li ion) or LFP, not suitable for LTO.Single Cell Voltage: 3.0-4.2VRecommended Battery Capacity: Below 30AHVoltage 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 workingBalance Current: 0.1V voltage difference 0.5A balance current, when the voltage difference is above 0.2V, the maximum balance current is 1.2AUnder Voltage Protection Sleep Voltage: The adjacent voltage difference is less than 0.03V, enter sleep modeSleep Current: 0.01mA.Package List:1 x Battery Active Equalizer1 x CableNote:1. It is not recommended to be compatible with low strings, the indicator light will flash and report an error. Make sure to check that each cell is properly wired and insulated before connecting the balance 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.
