## Description

Extend Battery Life + 1 Year or MoreSpecialized for keep up the voltage balance of batteries connected in series during the Charging and Discharging process, due to differences in the chemical composition and temperature of the battery cell that connected in series, It causes two battery charge and discharge differences even the battery is idle, also due to the different levels of self-discharge could lead to an imbalance between serially connected battery at charging process, because there are differences, it could make a battery excessive charge or discharge, and the other one insufficient charging or discharging.  BE battery equalizer can compensate both parties when the battery are connected in series as voltage difference exceeds 10 mV, then the battery equalization starts to work, Final achieved balance of the batteries set. It can be connected for long periods for automatically battery state of equilibrium.  HA02 battery equalizer is suitable for Lead-acid Batteries(VRLA), Lithium Iron Phosphate Batteries(LFP), Nickel Cadmium Secondary Batteries(Ni/CD), and Nickelmetal Hydride Secondary Batteries(Ni/MH). It starts work when the voltage higher than 2.4V, it means that this equalier can be used in a single cell battery range from 2.4V to 12V. One equalizer can connect 4 batteries once a time, if battery less than the 4, the extra cable can be vacant (positive and negative terminal should be avoided), does not affect the equilibrium effects. The equalizer is not affected with battery connection way, no matter in series or in parallel, both can work.  Specificattion: Battery nominal voltage : 4 × (2.4V/3.6V/6V/9V/12V) Optimizing current : 0-10A Quiescent current: 5mA(12V) 1.2mA(2.4V) Dimensions : 62×124×27 mm 0.5kg Protection: Reverse polarity protection Under voltage lock out : 1.8V   In the Box: 1 Battery equalizer1 User Manual

## Features

- the 48V Battery Equalizer can connect Four 12V Batteries by default, no matter in series or in parallel. the maximum compensation current is 10A. For 96V or higher voltages Battery group, multiple 48V equalizers can be connected in parallel.
- Intelligent Battery Voltage Equilibrium System - Keep Batteries in Heath Condition and Extend Battery Service Life
- Intelligent Protection: Reverse polarity protection, Low Voltage Disconnect to Provide longer Battery Life Time
- 1 Set for 4 Batteries Connection by Default (12V + 12 V + 12V + 12 V)
- Battery Equalizer is recommended for use in autos, boats, golf carts, motorcycles, solar, trucks, RV's, electric forklift batteries, and any other battery groups Configuration. Please Download the Battery Equalizer User Guide at Technical Specification Section

## Questions & Answers

**Q: Does this work in both the charging and discharging cycles?**
A: Yes.  I found a paper online  describing the technology.  As I recall, it was designed by a pair of Chinese engineers.  It is very clever.  Basically there are multiple coils/transformers, one per battery.   It cycles, connecting each battery in turn to it's coil which then builds up a magnetic field.  That  energy is then provided to the other battery' coil/transformers.  They then discharge the energy into their batteries.  The lowest voltage batteries accept the most power during the discharge.  It is keeping my 4 12v 100Ah AGM UPS batteries within .1 volts for three months so far.  That's down from .7volts without the balancer.

**Q: I just hooked this unit up and i hear a loud 12.5 khz squeal coming from it.  is this normal or should i return for replacement.**
A: Hi，Please check the equalizer is work or not, a little sound is normal in the equalizer as the current in it when it works.

**Q: Is there a link somewhere to get the detailed tech manual??????**
A: please visit https://zhcsolar.com/product/48v-battery-equalizer/ to find more details about the battery equalizing system

**Q: I am looking for a battery equalizer than will balance my two 5s (18v nominal, made up of 3.6v li-ion 18650 cells) in series. will this work?**
A: the maximum voltage to handle is 12v per cell, not recommended if the battery cell is 18v

## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    It works.
  

*by R***H on Reviewed in the United States on January 19, 2018*

I was having problems with the batteries on my ebike holding a charge. I figured one or two were not getting a full charge so I thought I'd try this before buying new batteries. I'm glad I did. I noticed a difference after the first charge and after the second charge they seemed to be back to normal. I really didn't expect much but I'm happy to say that this product actually works. I saved about seventy bucks over buying new batteries.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Simple investment worth installing.
  

*by W***L on Reviewed in the United States on December 21, 2018*

This was just what I was looking for. Battery storage is the most expensive part of an off grid system and this makes managing the charge super simple. Connection took about 20 minutes for two of these on my 490 ah 48 v system and where I was getting a split range of 12.9-14.1 on each battery, they were now all being the same voltage during the very important cc/CV charge cycle.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Keeps a perfect balance within a few hundreds of Volts
  

*by P***K on Reviewed in the United States on December 27, 2019*

does not get hot either, meaning that it works efficiently. The only thing they could have added maybe was an indicator LED, to visualise it works.  You have to measure the batteries, to see it works, but each time you do, you find almost perfect equilibrium. I'd buy it again
