Reverse polarity protection to prevent damage from incorrect wiring Low disconnect to battery life time Can be connected in series or in parallel for long term operation to automatically maintain balance across the battery state The battery equalizer automatically balances in a bank when it detects a difference of 20 mV between two batteries Key benefits Protects the system from wiring errors with reverse polarity protection Supports longterm use in series or parallel battery configurations to maintain balanced state automatically Balances batteries automatically when a voltage difference of 20 mV is detected, helping to equalize aging and performance Simple integration into existing battery banks without needing separate balancing equipment How it works The device monitors voltage differences between connected batteries When a difference of 20 mV is detected between two batteries, it activates to balance the cells It is suitable for longterm connection in either series or parallel configurations to maintain overall balance Compatibility and setup Designed for use in battery banks configured in series or in parallel Intended to maintain balanced state across batteries over extended periods Use scenarios Solar power storage: use with multiple 12V/24V batteries in series or parallel to maintain even charge and extend overall battery life Marine or RV battery banks: integrate into the onboard battery system to keep all cells balanced while parked or in use Backup power systems: apply to UPS or emergency power setups with stacked batteries to ensure consistent performance and longevity Notes Balance action is triggered by a detected imbalance of 20 mV between batteries Suitable for continuous or longterm operation within a mixed battery bank where series or parallel configurations are used
