Automatic charging control board for battery maintenance that manages charging and power cutoff automatically to provide intelligent, efficient, and safe charging. Key benefits Automatic control: Manages charging start and stop without manual intervention, simplifying battery maintenance and reducing the need for monitoring. Overvoltage protection: Cuts off charging when voltage reaches 148V to protect batteries from excessive voltage. Adjustable settings: Allows of both the startup charging voltage and the disconnect voltage for compatibility with different battery types and charging strategies. Stable switching thresholds: Features a relay closing voltage of 124V and a disconnect voltage of 148V to maintain consistent charging behavior and improve conversion efficiency. Reliable operation: Designed to give predictable, repeatable control of charge cycles for prolonged battery service life and reduced operational errors. Function and performance Fully automatic charging control and power cutoff to manage charge cycles without user intervention. Instant cutoff at 148V prevents overvoltage exposure. Relay closes at 124V to resume charging under controlled conditions. startup and disconnect voltages let you tailor the board to the voltage profile of your battery system. Compatibility Intended for battery systems that operate around the specified voltage thresholds, including large battery banks and charger systems that require precise voltage control. Suitable for integration into solar energy storage, backup power systems, and industrial battery charging setups where 124V and 148V thresholds are appropriate. Typical applications Solar power battery banks: Maintain safe charging and avoid overcharging in offgrid and hybrid systems. Backup and UPS battery systems: Automate charge control to ensure readiness and prevent overvoltage stress during float and recharge cycles. Industrial chargers and energy storage equipment: Provide predictable switch points for automated charging logic in voltage battery installations. What it solves Eliminates the need for constant monitoring by automating charge start and stop. Prevents damage from overvoltage by cutting power at 148V. Improves consistency and efficiency of charge cycles with fixed relay and disconnect thresholds and settings. Operation notes The board operates automatically based on the configured startup and disconnect voltages. Relay closing voltage is 124V; disconnect voltage is 148V. Adjust startup and disconnect points as required to match your battery chemistry and system requirements. This control board provides straightforward, voltagebased charging control for systems that require reliable automatic management at the specified thresholds.
