Active Equalizer 1.2A 4S Inductive Balancer Energy Transfer For Lithium Iron Phosphate Battery

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 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

How to Use:
Balance Instructions: 
1. When the equalization light is on, the equalization work is turned on,
2. When the equalization light is off, the equalization circuit is in sleep state,
3. The equalization light flashes, indicating that the string is dropped, or the circuit is faulty.

Package List:
1 x Active Balancer Board
1 x Cable

Note:
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.
