2-4.5V Active Balancer Board 1.2A Lithium Battery High-Precision Energy Transfer Balance Module with Cable Active Equalization Board
Feature:
1.Voltage Balancing Principle: The Lithium battery active equalizer module adopts a voltage balancing principle between adjacent batteries to trigger its internal balancing function when the voltage difference between adjacent batteries exceeds 0.1V. The balancing function continues until the voltage difference between neighboring batteries falls below 0.03V, reducing battery maintenance costs.
2.High-Precision Energy Transfer Balancing Function: This active equalization board is equipped with an exclusive balancing chip that provides high-precision energy transfer with a current of up to 1.2A. It can significantly balance the voltage difference between batteries, improving the efficiency of the entire battery pack.
3.Technical Parameters: The inductance energy transfer active balance board board has a working voltage range of 2.0V to 4.5V and is compatible with ternary and iron-cobalt lithium-ion batteries. The balancing current varies with the voltage difference between adjacent batteries, ranging from 0.5A to 0.7A at a voltage difference of 0.1V and up to a maximum of 1.2A at a voltage difference of 0.2V.
4.Wiring Definitions: The wiring definitions of the active balance module are clearly labeled, making it easy to connect the balancing board to the battery pack. B represents the total negative pole of the battery pack (i.e., the negative pole of the first battery), while B1, B2, B3, etc., represent the positive poles of the individual cells.
5.Compatibility: This active equalization balancer module is compatible with various battery packs used in electric vehicles, drones, and other applications, making it an ideal choice for those looking for reliable and efficient voltage balancing solutions.

 

Specification:
Model Number: Lithium Battery Active Equalization Board
Name: Inductance Energy Transfer Active Balance Board
Package size: About 8x12x0.5cm/3.15x4.72x0.19in

Technical Parameters:
Working voltage range: 2.0V-4.5V, common for ternary/iron bond batteries.
Balance current:
The adjacent voltage difference is above 0.1V (the current is about 0.5-0.7A); the adjacent voltage difference is above 0.2V (reaching the maximum balanced current of 1.2A); the smaller the voltage difference, the smaller the balanced current.
Wiring definition:
B1, 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, and so on.

Balance principle:
This module is adjacent voltage difference equalization, the adjacent battery pressure difference reaches 0.1V or more, the chip internally triggers equalization work, until the adjacent battery voltage difference is within 0.03V and stops working, there is an adjacent voltage difference when charging and discharging on the battery pack By triggering equalization work, the voltage error of the battery pack will also be pulled back to an ideal value, reducing battery maintenance costs.

Balanced version features:
High-precision energy transfer equalization, exclusive equalization IC, high-current 1.2A energy transfer battery voltage balancer, can significantly balance the battery voltage, and improve the overall efficiency of the battery pack.
