Features 1、IMPROVE EFFICIENCY: Inductive energy transfer balance board, high current 1.2A energy transfer battery voltage balancer can significantly balance battery voltage and improve the overall efficiency of the battery pack 2、WORKING PRINCIPLE: This module is the balance of adjacent voltage difference, the voltage difference between adjacent batteries reaches more than 0.1V, the chip will trigger the balance work, and stop working until the voltage difference between adjacent batteries is within 0.03V 3、REDUCE MAINTENANCE: When the battery pack is charged and discharged, there is an adjacent voltage difference to trigger the equalization work, and the battery pack voltage error will also be pulled back to an ideal value, reducing battery maintenance costs 4、LOW POWER CONSUMPTION: Built in improved ultra low internal resistance MOS, the balance current is 0‑1.2A, and the battery voltage difference is smaller. The smaller the current, the static power consumption does not exceed 20μA 5、RELIABLE PCB: Using excellent quality PCB materials, with reliability and miniaturization, good maintenance and interchangeability Specification Item Type: Battery Active Equalizer Material: PCB Harness Specification: 22AWG Technical Parameter: Working Voltage: 2.0V-4.5V, common for ternary iron lithium battery, not suitable for LTO lithium Titanate battery Balance Current: Adjacent voltage difference more than 0.1V (current about 0.5-0.7A); Adjacent voltage difference more than 0.2V (maximum equilibrium current 1.2A); The smaller the voltage difference, the smaller the equalizing current Wiring Definition: B-, the total negative pole of the battery pack (the negative pole of the first battery) B1, the positive pole of the first battery B2, the positive pole of the second battery B3, the positive pole of the third battery B4, the positive pole of the fourth battery Package List 1 x Active Balancer Board 1 x Cable
