About the HA02 Battery Equalizer
The HA02 Battery Equalizer (also called Battery Balancer) can connect Four 12V Battery by default, no matter in series or in parallel. the maximum compensation current is 10A. For 96V or higher voltage Battery pack, multiple 48V equalizers can be connected in parallel.
Features of the Battery Balancer:
Intelligent Battery Voltage Equilibrium System – Keep Batteries in Heath Condition to Prolong Battery Service Life
Intelligent Protection: Reverse polarity protection, Low Voltage Disconnect features to Protect the units during each state of charge soc
1 Set for 4 Batteries Connection by Default (Max 12V + 12 V + 12V + 12 V )
Battery Equalizer is recommended for use in autos, boats, golf carts, motorcycles, solar, trucks, RV, electric forklift batteries, solar system, and any other battery groups Configuration. also can work when there is a battery charger connected to the battery.
The principle of Batteries Cell Balancing:
the 48V Battery Balancer is Specialized for keep up the voltage balance of connected battery in series during the Charging and Discharge cycle, due to differences in the chemical composition and temperature of the individual cells 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 a charging process, because there are differences, it could make a battery excessive charge or discharge, and the other one insufficient charging or discharging.
HA02 battery equalizer can compensate both parties when the battery is connected in series as voltage difference exceeds 10 mV, then the battery equalization starts to work, Final achieved the passive balancing of the batteries set. It can be connected for long periods for automatically battery state of equilibrium.

How to use the Battery Balancer Ha02
48V battery equalizer is suitable for Lead-acid Battery (VRLA), Lithium Iron Phosphate Batteries(LFP), Nickel Cadmium Secondary Batteries(Ni/CD), and Nickelmetal Hydride Secondary Batteries(Ni/MH) lithium ion. It starts work when the voltage higher than 2.4V, it means that this equalizer 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 by battery connection way, no matter in series or in parallel, both can work.

How Customer Talks about the Balancer
Perfect protection for 2 new strings of 8A8D 12-volt batteries wired in series for 48-volts. The solar & grid chargers were not dividing the voltage equally across the AGM batteries, and some were getting almost 2 volts too much! This would surely have destroyed my new 5,000 dollar battery investment. The battery bank is 1/4 if the system cost. Would have been nice to have just a couple more inches if wire leads and 4 fuses built inline with the leads. These units do “exactly” what they say they’ll do… balance battery voltages when charging and discharging. Will be ordering a spare or two to have on hand in the event they go bad and are discontinued. The entire off-grid solar power system relies on these small balancers.
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.

These work surprisingly well. You can measure the current flow between the batteries to see that they really are balancing them

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.

Works really well. Batteries all within .07 volts.
