12V Energy Transfer for Lithium Battery Lifepo4 BMS 4S, 1.2A Balance Board, Active Balancer

Features:

Balance principle: This module is for balancing adjacent voltage differentials. When the voltage difference between adjacent batteries reaches 0.1V or above, the chip triggers the balancing operation internally until the adjacent battery voltage difference stops working within 0.03V. When used on the battery pack for charging and discharging, there is an adjacent voltage difference that triggers the balancing operation. The voltage error of the battery pack will also be pulled back to a relatively ideal value, reducing battery maintenance costs.

Balanced version features:

High precision energy transfer balancing, exclusive balancing IC, high current 1.2A energy transfer battery voltage balancer, significantly balancing battery voltage, and improving overall battery pack efficiency.

 

Specification:

Technical parameters:

Working voltage range: 2.0V-4.5V, universal for ternary/lithium iron batteries.

Balanced current:

Adjacent voltage difference above 0.1V (current between 0.5-0.) Around 7A);

Adjacent pressure difference of 0.2V or above (reaching maximum equilibrium current of 1.2A);

The smaller the pressure difference, the smaller the equilibrium current.

Wiring definition:

B-， The total negative electrode of the battery pack (the negative electrode of the first battery)

B1， The positive pole of the first battery section

B2， The positive pole of the second section battery

B3， Third battery positive terminal and so on.

Note: 1. Confirm the serial sequence of the batteries.

2. Strictly follow the drawings to connect the wiring and confirm that there are no errors before inserting the board.

 

Package Include:

1Pcs*Balance board module
