Battery Equalizer – 4x Battery Balancer for 12V Systems

HA02 Energy Transfer Battery Equalizer – 4x Battery Balancer for 2.4V–12V Systems

Keep your 12V series battery banks balanced, efficient, and long-lasting with the HA02 Energy Transfer Battery Equalizer. Designed to support any configuration of 4-series or parallel battery banks with voltages of 2.4V, 3.6V, 6V, 9V, or 12V, this intelligent equalizer automatically redistributes energy between batteries to prevent premature aging and voltage imbalances.

Once a voltage difference as small as 10mV is detected, the HA02 begins transferring energy from higher-voltage batteries to lower-voltage ones, ensuring uniform performance across the entire system. Whether your batteries are charging, discharging, or idle, this device safeguards their health and enhances lifespan.
