QINIZX12S 36V 48V 50.4V 1.2A Li-ion Lipo Lifepo4 LFP Battery Active Equalizer BMS Balancer Inductive Balance Lithium Battery Energy Transfer Board (12S)
Main highlights- Voltage balance accuracy: 30mV (typical value) between adjacent voltages; Balance current: 0.1V
0.2V, balanced current 1.0A (max 1.2A); Under-voltage protection dormant voltage: The adjacent voltage difference is less than 0.03V and enters dormant state, Sleep current 10uA. - Tips: The equalization board is not a BMS protection board, it is an auxiliary to the protection board, so no matter how bad the battery you use to test, it can be used, But it has no overvoltage/overdischarge protection function. Overvoltage/overdischarge is the function of the BMS protection board. If voltage protection is required, it is best to use it in parallel with the BMS protection board.
- NOTE: Only can use 12s battery-packs, and Not recommended to use poor quality battery pack to test. The indicator light will flash and report an error. Before connecting the equalization board, be sure to check whether each battery is wired correctly(Measure whether the voltage of each battery string is correct), and do a good job of insulation. otherwise it will short-circuit and burn the board.
- Balance method: Detect that the voltage difference between adjacent batteries is greater than 0.1V to trigger the start of equalization, and the adjacent battery voltage difference is less than 0.03V to stop working. (Tips: The inductance equalization board needs to be charged/discharged many times before the voltage equalization can achieve a better effect.)
- Applicable battery type: NCM(Li-ion)/LFP, NOT support LTO; Single voltage working range: 3.0V-4.2V; Suggested battery capacity: below 30AH, If more than 30AH, pls search Capacitor Faster Whole Group Balancer " B096NLHXPF " to purchase. Indicator light: LED on, balance in progress; LED off, balance ends; LED flashing: battery drop string indicator/circuit failure.
