## Overview

This 3S/4S 12V 5A Battery Active Equalizer is a high-precision capacitor-based balancer designed for Li-ion and LiFePO4 batteries. Featuring ultra-low resistance MOSFETs and a thick copper PCB, it delivers up to 5.5A balancing current with 5mV accuracy. The module includes smart under-voltage sleep protection to safeguard battery health and supports battery packs from 30 to 200AH, scalable via parallel connections. Its compact design and user-friendly RUN pad switch make it an essential upgrade for professional-grade battery management.

## Description

3S 4S 12V 5A Battery Active Equalizer BMS Balancer Lipo Li-ion LFP LiFePO4 Lithium Battery Balance Active Energy Transfer Equalization Module Faster Whole Group Capacitor Balancer PCB

## Features

- Working Voltage: 2.7V-4.2V, suitable for NCM Ternary polymer lithium battery (Li-ion), lithium iron phosphate battery (LiFePO4). It can Not fit LTO battery. 【NOTE Tips】Well tested by the manufacturer. As long as the wiring is correct, the product guarantees long-lasting and effective performance. Of course, if customers have any questions, they can take the initiative to contact us, we are absolutely capable of providing more professional answers, rather than a direct refund returns.
- Working Principle: Flying capacitor transfer charge transporter, Balancer board is connected to the battery to start the balance work, using the original brand new ultra-low internal resistance MOS, 2OZ copper thickness PCB. Balance current 0-5.5A, the more balanced the battery current is Small, reserved for the dormant switch wiring position, the dormant power-off mode working current is less than 0.1mA, and the balance voltage accuracy is within 5mv!
- The quiescent current is about 9mA, and the battery capacity is recommended to be used between 30-200AH/Per Balancer. High-capacity batteries can be connected in parallel with multiple equalizers.
- With under-voltage sleep protection, only detecting the battery voltage of B1, the equalizer will automatically stop entering the sleep state when the B1 voltage is lower than 2.7V, and the standby power consumption is less than 0.1mA.
- 【NOTE】: Before connect the balance cable to the balance board, be sure to check whether the connections of each section of the battery pack are correct, and do a good job of insulating the bottom of the board and the battery string connection terminals. Otherwise, it will short-circuit and burn the board. Tips: This balancer board is backward compatible by default. eg. If it is used for 3S, the last line B4+ is empty.
