SUNON Battery Balancer 48V

The Problem

It is found that when the batteries are used in series, the voltage of each battery will be slightly different.

Well, this may not be a big problem. But after more than 6 months, the difference will become bigger.

Large differences will result in damage due to excessive gassing (caused by overcharging) of the batteries with the higher initial state of charge and sulphation (caused by undercharging) of the batteries with the lower initial state of charge.

Instead of replacing the batteries, we want to improve it from the beginning.

The Good Solution

We came up with an idea.

Transfer the excess power from the overcharged battery to the undercharged battery.

After 6 months of research and 12 months of testing and improvement, we released this product.

By keeping the battery voltage consistent, the performance of the batteries in the group is also significantly enhanced.

Benefits

Sunon Battery Balancer can provide you with:

Longer battery life, 1 year or more

Significantly reduce the possibility of battery replacement

Consistent charging and discharging, better battery bank performance

How does it work?

When the voltage of one battery is 10mV higher than another, Sunon battery balancer starts to work.

Current flows from the higher voltage battery to the lower one, until the voltage is equal.

The maximum compensation current is 10A, which can fulfill most battery banks.

FAQ:

How does Sunon Battery Balancer work?

Sunon Battery Balancer is an energy transfer equalizer.

When the voltage difference between the batteries in series exceeds 10mV, the balancer begins to work. The current flows from the higher voltage batteries to the lower ones.

The maximum compensation current is 10A.

When does the balancer start to work?

The balancer starts to work when the voltage difference between the 2 batteries in series exceeds 10mV.

Can Sunon Battery Balancer be used while charging? Can the voltage be equalized even when discharging?

It can.

Sunon Battery Balancer can be used while charging and discharging.

It will equalize the voltage while charging and discharging.

Can the balancer be used on Lithium batteries?

Yes.

Sunon Battery Balancer can be used in lead-acid batteries, lithium batteries (including lithium iron phosphate batteries), nickel-cadmium batteries, and nickel-hydrogen batteries.

Can I use it in a 12V, 24V, or 96V battery pack?

If it’s a single 12V battery, it’s not necessary.

In the case of a 24V battery pack, 2 batteries connected in series. You can use only 2 sets of the balancer terminal blocks.

But please keep on the other 2 sets of PVC sleeves to avoid short circuit.

For a 96V battery pack, more balancers can be used in parallel.

We are also offering battery balancer models for 24V, 60V, 96V.
