4S 12V 16.8V 1.2A Li-ion Lipo Lifepo4 LFP Battery Active Equalizer BMS Balancer Inductive Balance Lithium Battery Energy Transfer Board (4S)
- 【NOTE】: Not recommended to be compatible with low strings, The indicator light will flash and report an error. Before connecting the equalization board, be sure to check whether each battery is wired correctly, and do a good job of insulation. otherwise it will short-circuit and burn the board. LED on: balanced (corresponding to energy transfer balance between adjacent batteries); LED off: equalization ends; LED flashing: drop string indication/circuit malfunction.
- 【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.
- 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.
- 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.)
- Voltage balance accuracy: 30mV (typical value) between adjacent voltages; Balance current: When the Adjacent battery voltage difference is 0.1V~0.2V, balanced current in 0.5A-0.7A; Adjacent battery voltage difference is greater than 0.2V, maximum balanced current 1.2A. Static working current: 0.01mA; Under-voltage protection dormant voltage: The adjacent voltage difference is less than 0.03V and enters dormant state.

3S 4S 12V 5A Battery Active Equalizer BMS Balancer Lipo Li-ion LFP LiFePO4 Lithium Battery Balance Active Energy Transfer Equalization Module Faster Whole Group Capacitor Balancer PCB
- Working Voltage: 2.7V-4.2V, suitable for NCM Ternary polymer lithium battery (Li-ion), lithium iron phosphate battery (LiFePO4). It can Not fit LTO battery. 【NOTE Tips】Well tested by the manufacturer. As long as the wiring is correct, the product guarantees long-lasting and effective performance. Of course, if customers have any questions, they can take the initiative to contact us, we are absolutely capable of providing more professional answers, rather than a direct refund returns.
- Working Principle: Flying capacitor transfer charge transporter, Balancer board is connected to the battery to start the balance work, using the original brand new ultra-low internal resistance MOS, 2OZ copper thickness PCB. Balance current 0-5.5A, the more balanced the battery current is Small, reserved for the dormant switch wiring position, the dormant power-off mode working current is less than 0.1mA, and the balance voltage accuracy is within 5mv!
- The quiescent current is about 9mA, and the battery capacity is recommended to be used between 30-200AH/Per Balancer. High-capacity batteries can be connected in parallel with multiple equalizers.
- With under-voltage sleep protection, only detecting the battery voltage of B1, the equalizer will automatically stop entering the sleep state when the B1 voltage is lower than 2.7V, and the standby power consumption is less than 0.1mA.
- 【NOTE】: Before connect the balance cable to the balance board, be sure to check whether the connections of each section of the battery pack are correct, and do a good job of insulating the bottom of the board and the battery string connection terminals. Otherwise, it will short-circuit and burn the board. Tips: This balancer board is backward compatible by default. eg. If it is used for 3S, the last line B4+ is empty.
