## Overview

The 3S 4S 5A Active Equalizer is a high-performance battery balancing board designed for LiFePO4 and NCM ternary polymer batteries between 60-300AH. It actively transfers charge between cells with up to 5.5A current, improving battery lifespan and charge efficiency without external power. Featuring smart sleep protection below 3V and a durable 2OZ copper PCB with ultra-low resistance MOSFETs, it ensures safe, efficient balancing. Comes with a test board for easy installation and monitoring, making it an essential upgrade for serious battery management.

## Description

Product Describtion: Model:3S-4S Suitable : Lithium Iron Phosphate, NCM Ternary Polymer,(Not Fit Lithium Titanate)Voltage is 1.8 V-4.5V Quiescent Current: 12mA Suggest Battery Capacity: 60-300AH Working Temperature :-20 degrees to +60 degrees Sleep Protection:voltage<3V, enter the sleep,standby power consumption is less than 0.1mA,to reduce the damage to the battery. Safety Information：Before connecting the equalization board, check whether each piece of wiring is correct, and do insulation work to prevent burnout,This is very important, please pay attention. NOTE: If the LED indicator is always on, it means that the capacitor plate has been running in a balanced manner. When a fault occurs, the LED indicator will go out. Package Included:1*3S 4S 5A Active Equalizer Lifepo4 Lipo Lto Lithium1*Test Board

Review: Works good.
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.

## Features

- [Product Information]: Before connecting the equalization board, check whether each piece of wiring is correct, insulation between the bottom board and the battery connection terminals is required to prevent burnout.Model:3S-4S Suitable : Lithium Iron Phosphate, NCM Ternary Polymer,(Not Fit Lithium Titanate) ,Voltage is 1.8 V-4.5V ,Suggest Battery Capacity: 60-300AH.
- [Capacitance Principle]: No external power supply is required,The working principle is Capacitor fit transfers the charge transporter, use the internal energy transfer of the battery to transfer and balance the entire battery pack.the equalization board can be connected to the battery to start the equalization work.
- [Protection switch]: With sleep protection, when the voltage is lower than 3V, it will automatically stop and enter the sleep state to reduce the damage to the battery.
- [Original Design]:using the original ultra-low internal resistance MOS, 2OZ copper thickness PCB, equalizing current 0-5.5A, The more balanced the battery, the lower the current.
- [Satisfactory Service]: We Provide 24-hour online service,If you encounter any problems, Please email SELLER SUPPORT (Not desertcart support), we will give you a perfect solution.

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.
