## Overview

The Cywhrvzsf 3S 4S 5A Balance Li-ion Lifepo4 Equalization Module is a high-precision battery balancer designed for NCM ternary polymer lithium and LiFePO4 batteries between 30-200AH. Operating within 1.8V-4.5V and up to 60°C, it features ultra-low internal resistance components and a 5.5A balancing current to optimize battery pack health. With built-in under-voltage sleep protection and no need for external power, it ensures efficient, safe, and automatic cell equalization, making it an essential upgrade for professional-grade battery management.

## Description

It can Not fit LTO .3.he quiescent current is about 9mA, and the capacity is recommended to be used between 30-200AH/Per Balancer.4.Working environment temperature 0-60 degrees.5.With under-voltage sleep protection, the voltage will automatically stop entering the sleep state when the voltage is lower than 2.7V, and the standby power consumption is less than 0.1mA.6.Working principle, the capacitor fit transfers the charge mover, the equalization board is connected to the , and the equalization is started. The original new ultra-low internal resistance MOS, 2OZ copper thickness PCB.Equilibrium current 0-5.5A, the more balanced the , the smaller the current, with manual sleep switch, sleep current mode is less than 0.1mA, the balance voltage accuracy is within 5mv.Safety Information：[NOTE]: Before connecting the equalization board, be sure to check whether each is wired correctly, and do a good job of insulation. otherwise it will short-circuit and burn the board.This is very important, please pay attentionPackage Included:1*3S 4S 5A Balance Li-ion Lifepo4 Lithium 1*6S 7S 8S 5A Balance Li-ion Lifepo4 Lithium

Review: Bought some 200AH LIFEPO4 drop in batteries (non-smart) and had issues reaching above 13.8v during charge, with more than half of them... I had some suspicions one cell or more were reaching 3.65v before the rest. They still pulled capacity so support wasn't much help. After cracking one open, I confirmed the imbalance. This balancer worked perfectly, and was able to sort out the imbalance in a few hours of on/off tinkering. Just make sure you wire it up right. I'm cautious so I monitor that no cell goes over 3.65v (LIFEPO4) and let it get to work. Now I can charge to the proper 14.2-14.6v on these batteries. Many cheap drop in batteries have a BMS that either doesn't balance, or if it does, it's at a pathetic rate of 30ma or so. This seems to be good quality including the case and 18awg balance leads. Highly recommend this active balancer with case! Only wished they also included a small wiring diagram in box. Saved screenshot from desertcart, so wasn't an issue, but it's my only complaint.
Review: I mean it's simple electrical theory - this balancer should work well. I just didn't think it would work THIS well....especially for the price. I have 16 * 300Ah 3.2v cells that were pretty out of balance, and this balancer got them balanced within a few days! The battery bank is on a Daly BMS which is *supposed* to have balancing, but clearly was not effective. I put this balancer on top of it, and all cells are now almost perfectly balanced.

## Features

- [Working Voltage]: 1.8V-4.5V, suitable for NCM Ternary polymer lithium (Li-ion), lithium iron phosphate (LiFePO4). It can Not fit LTO .The quiescent current is about 9mA, and the capacity is recommended to be used between 30-200AH/Per Balancer.Working environment temperature 0-60 degrees.
- [Working Principle]: Working principle, the capacitor fit transfers the charge mover, the equalization board is connected to the , and the equalization is started. The original new ultra-low internal resistance MOS, 2OZ copper thickness PCB.Equilibrium current 0-5.5A, the more balanced the , the smaller the current, with manual sleep switch, sleep current mode is less than 0.1mA, the balance voltage accuracy is within 5mv.
- [Sleep Protection];With under-voltage sleep protection, the voltage will automatically stop entering the sleep state when the voltage is lower than 2.7V, and the standby power consumption is less than 0.1mA.
- [No Need External Power ]:no external power supply is required, and the internal energy transfer of the is used to transfer and the entire set batteries pack in balance .Before connect the balance cable to the balance board, be sure to check whether the connections of each section of the pack are correct, and do a good job of insulating the bottom of the board and the string connection terminals. Otherwise, it will short-circuit and burn the board.
- [Satisfactory service]:If you encounter any problems, please contact us, we will give you a satisfactory solution.
