Active Battery Balancer 10A for 4‑8S Lithium Packs, Efficiency Energy Saving Equalizer with Smart Sleep Mode Description

Active Battery Equalizer for MultiString Lithium Packs Overview A compact PC material active equalizer designed for multistring lithium battery packs. It connects to a minimum of four strings, supports extended series connection, and improves balance and parallel efficiency by transferring energy across the entire pack. Key benefits Maintains consistent voltages across strings to reduce imbalance and improve usable capacity. Flexible deployment for hobby,, and stationary battery packs; can work alongside a BMS in parallel for long term installations. Automatic and configurable sleep behavior conserves energy and limits unnecessary balancing when not needed. Variable balance current that scales with voltage difference for efficient energy transfer without a fixed drain. Main functions and modes Whole group synchronous balance using energy transfer across strings for uniform pack balancing. Two balance modes: a mode that automatically disables and sleeps when cell voltage drops below 3.0 V, and an active mode that remains continuously on. After the pack reaches balance, the unit automatically sleeps for 1 hour, then rechecks voltage differences and resumes balancing if required. Sleep switch available: Off for continuous operation, On to enter sleep after 8 hours of operation. Sleep state is also automatically triggered during charging and discharging events. Multiple units of the same model can be connected in series for extended voltage ranges while maintaining synchronized balancing to improve conversion efficiency. Specifications Item type: Active Battery Equalizer Material: PC Balance method: Energy transfer, whole group synchronization Supported battery types: Ternary and lithium iron phosphate Minimum start condition: First 4 strings total voltage must be at least 12 V Start differential pressure: None required Stop condition: Operation will stop if working voltage exceeds 10 V Balance current: Variable with voltage difference; at 0.1 V difference current about 1.2 A, maximum up to 10 A Power supply: Selfpowered by the first 4 strings Low voltage protection: Shutdown if any single string falls below 2.5 V or if the first four strings fall below 10 V Temperature protection: Shutdown at 50 degrees C, resumes at 45 degrees C Working power consumption: Max 0.2 W; static consumption 0.01 W Communication: No Bluetooth support Practical applications RC and model battery: Restore balance and extend usable life of multistring hobby packs. Stationary battery banks: Improve parallel efficiency and maintain long term packs when used in parallel with a fixed BMS. Custom series packs: Use multiple equalizers of the same model to support extended series configurations while keeping cells balanced. What to expect Reliable, lowpower balancing that adapts current to voltage differences and provides configurable sleep behavior. Suitable for both ternary and lithium iron phosphate chemistries, the unit is designed to integrate with existing battery packs and BMS arrangements without added communication interfaces.
