Bidirectional voltage compensation for balanced battery packs Automatically balances charge and discharge across seriesconnected batteries with a 05 A compensation current, helping maintain consistent voltages and prevent cell degradation in 24 V, 36 V, and 48 V systems. Protective features to extend battery life Builtin reverse polarity protection and low voltage disconnection at 10 V safeguard the battery bank from accidental wiring errors and deep discharge, contributing to longer overall battery life and safer operation. Clear monitoring and maintenance insights LED status display provides a straightforward visual indication of realbalancing activity, delivering immediate feedback on system performance to simplify maintenance and troubleshooting. Compact, lightweight, and versatile design Measures 70 x 70 x 27 mm and is lightweight, enabling easy installation in tight spaces. Designed to support various configurations, including N x 12 V battery arrangements, for flexible integration into existing setups. Use scenarios Offgrid solar storage: In a 24 V, 36 V, or 48 V solar energy system with seriesconnected cells, the balancer helps maintain equalized voltages to optimize performance and extend pack life. Recreational vehicles and marine applications: For N x 12 V battery banks used in RVs, sailboats, or living aboard, the device keeps all cells balanced during charging and discharging cycles. Small backup and telecom systems: In multibattery strings powering backup power or auxiliary telecom equipment, it prevents imbalancerelated stress and supports reliable operation.
