Battery voltage balancer and LED display power manager designed to keep series battery systems safe, balanced, and reliable. Key benefits — why you need it Prevents uneven cell aging and premature battery failure by maintaining charge/discharge balance across series batteries. Keeps LED displays and other loads stable with intelligent voltage regulation, reducing flicker and downtime. Protects the system from damage with reverse polarity protection and automatic lowvoltage disconnection. Reduces maintenance: automatic dualdirection compensation balances current during both charge and discharge without manual intervention. Core functions and performance Charge/discharge balance management for series battery systems to support stable LED display operation. Intelligent voltage regulation to extend overall battery lifespan and improve display reliability. Automatic dualdirection compensation that balances current in both charging and discharging directions. Current balancing capability up to 10A. Very low standby consumption: 2 mA at 2.4V up to 5 mA at 12V. Builtin safety: reverse polarity protection and lowvoltage disconnection activate at 10V undervoltage or if incorrect polarity is detected. Compatibility Works with standard series battery voltages: 24V, 36V, 48V and other N × 12V configurations. Supports cell setups from 2.4V to 12V, suitable for a wide range of industrial battery arrangements. What makes it stand out Automatic, bidirectional balancing removes the need for manual equalization. 10A balancing capacity supports demanding loads and faster correction of imbalances. Low quiescent current minimizes parasitic drain on batteries during long deployments. Safety features engage at a defined 10V threshold to prevent damage and preserve system integrity. Typical applications LED advertising billboards and large display walls: maintains consistent brightness and prevents cell imbalance across long battery strings. Stadium or stage LED displays and control systems that require uninterrupted, stable power for reliable operation. Industrial backup battery banks and distributed power systems using seriesconnected cells where automatic balancing and protection reduce maintenance and extend service life. Simple operational advantages Install in series battery systems to enable continuous balancing while the system charges and discharges. No manual monitoring required for routine balancing; the unit operates automatically and conservatively to preserve battery health. Safety cutoffs and polarity protection reduce risk during installation and longterm service. Specifications (as provided) Compatible voltages: 24V, 36V, 48V, N × 12V configurations.
