Feature: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 pack2. 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 0.03V3. 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 costs4. LOW POWER CONSUMPTION: Built in improved ultra low internal resistance MOS, the balance current is 01.2A, and the battery voltage difference is smaller. The smaller the current, the static power consumption does not exceed 20A5. RELIABLE PCB: Using excellent quality PCB materials, with reliability and miniaturization, good maintenance and interchangeabilitySpecification:Item Type: Battery Active EqualizerMaterial: PCBHarness Specification: 22AWGTechnical Parameter: Working Voltage: 2.0V-4.5V, common for ternary iron lithium battery, not suitable for LTO lithium Titanate batteryBalance 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 currentWiring Definition: B-, the total negative pole of the battery pack (the negative pole of the first battery)B1, the positive pole of the first batteryB2, the positive pole of the second batteryB3, the positive pole of the third batteryB4, the positive pole of the fourth battery.Package List:1 x Active Balancer Board1 x CableNote:Because of the working principle of adjacent equalization, it cannot be used as a maintenance tool. To connect to the battery, it must be used together with lithium battery protection. The voltage difference generated by charging and discharging triggers the work of the equalizing plate to realize energy transfer and equalization.
