Battery Charging Equalizer 12V – Compatible with 24V / 36V / 48V Systems, Gel, AGM, Lead-Acid

The battery equalizer is an essential device for maintaining the health of 12V battery systems connected in series. Used in 24V, 36V, or 48V applications, this module ensures voltage balancing between batteries, preventing premature degradation and maximizing battery lifespan.

Over time, voltage differences that occur during charge/discharge cycles affect battery performance. Some batteries become overcharged while others remain undercharged. The equalizer detects differences greater than 20mV and automatically transfers current from the higher-voltage battery to the lower-voltage one, balancing the system without manual intervention.

Ideal for: solar systems, electric vehicles, UPS systems, or any configuration with batteries in series.
