About the HA02 Battery Equalizer
The HA02 48V Battery Equalizer is a kind of Active Battery Balancer, the 48v balancer is designed by ZHCSolar to achieve the battery bank equilibrium of voltage and power.
the 48V Equalizer support max 4 × 12V Batteries Connection by default. No matter the bank is series or parallel connected.
To equalizing 60V,72V,96V Battery Bank, multiple 48V Battery Balancer can be parallel installed.
48V battery equalizer is suitable for equalizing Lead-acid Battery (VRLA), Lithium Iron Phosphate Batteries(LFP), Nickel Cadmium Secondary Batteries(Ni/CD), and Nickel-metal Hydride Secondary Batteries(Ni/MH) lithium-ion Battery.
It starts work when the voltage difference 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), it does not affect the equilibrium effects.
The equalizer performance is not affected by the battery connection method, no matter in series or in parallel, both works.
Features of the 48V 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.

Nice value battery balancer, works great

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 event they go bad and are discontinued. The entire off-grid solar power system rely on these small balancers.

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.

great battery balancer , seems good

Works really well. Batteries all within .07 volts.

Most recommended for 48 v battery banks. Especially off grid battery banks.
The device is easy to connect. It does appear to improve the operation of my old batteries. The unit is sealed/ potted but do not get it wet. The unit emits a high pitched noise, but do to its theory of operation that would appear to be normal.

Keeps a perfect balance within a few hundreds of Volts
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

Si pude ver como las baterías fueron igualando los valores de carga. Tardó mas de 24 horas.
