Product controller that protects batteries, controls charging and loads, and prevents overheating — designed to extend battery life, reduce downtime, and protect connected equipment. Key benefits Protects your battery and loads: built-in over-discharge, over/under-voltage, and load-overcurrent protection prevent permanent battery damage and costly equipment failures. Simplifies operation and saves energy: manual timer and light-control options let you automate charging and lighting to match usage patterns and reduce waste. Improves safety and reliability: whole-unit temperature monitoring prevents overheating before it causes damage, increasing system uptime and reducing maintenance. Core functions (what it does) Battery over-discharge / over-voltage / under-voltage protection: monitors battery voltage and disconnects or limits operation to prevent deep discharge or harmful over-voltage conditions. Load discharge current overload protection: detects and interrupts excessive load current to protect wiring, loads, and the battery. Timer mode: manually set charge start (open) and stop (close) times to control when charging occurs. Light control with adjustable delay: when light control is enabled, the unit can switch lighting and you can set the light-on duration via a delay timer. Whole-machine overheat protection: continuously monitors temperature of the device and acts to prevent thermal damage. Compatibility, construction, and performance notes Intended for battery-based systems and connected loads where voltage, charge timing, light control, and thermal protection are required. Compact, durable design for installation in equipment cabinets, small enclosures, or on-site control boxes. Focused on reliable protection and straightforward control rather than complex programming — easy to integrate with existing battery and lighting setups. Practical use scenarios Solar garden or pathway lighting: use light control plus time delay to keep lights on for a preset number of hours after dusk while protecting the battery from over-discharge on cloudy days. Off-grid cabin or RV systems: use timer mode to schedule charging periods and prevent overloading when multiple appliances draw power, extending battery lifespan. Backup power and remote equipment: protect batteries and critical loads from overcurrent and overheating, and set charging windows to match generator or grid availability. What you get Multiple layered protections for battery and load Manual timer for charge control Light-sensing control with adjustable on-duration Temperature-based shutdown to prevent overheating This controller is designed to be a dependable protective and control element in any battery-powered lighting, charging, or backup-power application.
