Equalizer / Charge Distributor for 24V Batteries – Optimization & Longevity

Optimize your battery lifespan with this 24V charge equalizer, specially designed to maintain an optimal balance between batteries in series or parallel. It acts as soon as the system voltage reaches 27 V, ensuring uniform charging and significantly extending the lifespan of your battery banks.

✅ Intelligent operation

When the voltage exceeds 27 V, this distributor automatically compares the voltage of the two 12 V batteries connected in series. It draws a compensating current (up to 1 A or 5 A depending on the models) from the more charged battery to the less charged one. Result: an automatic balancing, silent and efficient.

✅ Why use a balancer?

• Prevents overcharging or undercharging of series/parallel elements
• Reduces the risk of sulfation or gas release
• Extends the lifespan of your batteries (lead, AGM, GEL...)
• Optimizes the overall efficiency of your solar or wind system

✅ Compatibility & Installation

• Perfect for 24V or 48V battery banks
• For a 48V configuration, three balancers are required
• Multiple balancers can be installed in parallel
• Ideal for autonomous solar installations, remote sites, boats, RVs, industrial parks

⚠️ Common issue: charge imbalance

A single slightly weaker or new battery can lead to:

• Overcharging of weaker elements
• Undercharging of new batteries
• Overall imbalance compromising the performance and longevity of the bank

💡 The solution: our charge distributor ensures an identical state of charge across all batteries, eliminating these risks.

The battery equalizer equalizes the state of charge of two series-coupled cells, or of several parallel battery banks connected in series.

When the charging voltage of a 24V battery system rises above 27V, the battery balancer turns on and compares the voltage of the two series-connected batteries. The battery equalizer will then draw a current (up to 1A) from the most charged battery (or batteries connected in parallel). The resulting differential current charge will ensure that all cells converge to the same state of charge. It will extend the charge state of your battery banks.

If necessary, multiple distributors can be connected in parallel (see diagram at the bottom of the article).
A 48 V battery bank can be balanced with three battery balancers.

Problem: The lifespan of a battery bank, which is expensive, can be significantly reduced due to charge imbalance.

A battery with a slightly higher internal leakage current in a 24 or 48 V bank composed of several batteries connected in series/parallel will cause undercharging of the batteries connected in parallel, and the batteries connected in series to be overcharged. Moreover, if new cells or batteries are connected in series, they must have the same initial state of charge. Small differences will dissipate during the absorption or equalization phase of the charge, but larger differences will cause damage due to either excessive gassing of the batteries with a high initial state of charge (caused by overcharging), or sulfation of the batteries with a low initial state of charge (caused by undercharged batteries).

The solution: battery charge balancing

The distributor equalizes the state of charge of two 12 V batteries connected in series, or several strings of batteries connected in series. These strings are themselves connected in parallel. If the charging voltage of a 24 V battery system rises above 27.3 V, the battery balancer will turn on and compare the voltage on the two batteries connected in series. The distributor will extract a current of up to 5.0 A from the battery (or batteries connected in parallel) with the highest voltage. The resulting charge current difference will ensure that all batteries converge to the same state of charge.

If applicable, multiple balancers can be installed in parallel. A 48 V battery bank can be balanced with three battery equalizers.
