Specification Brand : XFYBZN BulletPoint : DC 12V 4500mAh Lithiumion Super Rechargeable Battery AC Power Charger US Plug BulletPoint1 : Balanced features: This module is an active equalization module for the voltage difference between adjacent batteries. High-precision energy transfer equalization, exclusive balanced IC, high current 1.2A energy transfer battery voltage balancer, significantly balancing battery voltage, improving overall battery pack efficiency. BulletPoint2 : Applicable battery type: NCM(Li-ion)/LFP, NOT support LTO; Single voltage working range: 2.0V-4.5V; Static working current: 0.01mA; Suggested battery capacity: below 30AH, If more than 30AH, pls choice high efficiency flying capacitance equalization, search " "to purchase. BulletPoint3 : 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, the board enters under-voltage protection dormant state. BulletPoint4 : Voltage balance accuracy: 30mV (typical value) between adjacent voltages; Balance current: 0.1V voltage difference 0.5A-0.7A balance current, the maximum balance current is 1.2A when the voltage difference is above 0.2V. The smaller the voltage difference between adjacent batteries, the smaller the equalizing current. BulletPoint5 : Package included: 1x 8S Balancer Module with 9pin cable, Board size: 2.4x2.3inch, cable length 1.14ft. Tips: If you encounter any problems, please contact us, we will give you a satisfactory solution.

The internal trigger balance is working until the adjacent battery voltage difference stops within 0.03V. There is an adjacent differential voltage when charging and discharging on The battery pack. Trigger balance, the battery pack voltage error will be pulled back to the ideal value, reducing battery maintenance costs. Balanced Board Features: High-precision energy transfer equalization, exclusive balanced IC, high current 1.2A energy transfer battery voltage balancer, significantly balancing battery voltage, improving overall battery pack efficiency. Technical Parameters: Operating voltage range: 2.0V-4.5V, Li-ion/Lipo/Lifepo4/18650 lithium battery universal. Balance Current: Adjacent voltage difference is 0.1V or more (current is about 0.5-0.7A); Adjacent voltage difference is above 0.2V (maximum balance current is 1.2A); The smaller the differential voltage , the smaller the balance current.
