This device provides clear, practical battery monitoring and control for charging and discharge applications. Key benefits Realtime battery information: LED indicators show current battery condition at a glance, so you can monitor charge status without additional tools. Safer, more efficient charging: Builtin protections prevent overcharge, short circuits, and reverse connection during charging, reducing the chance of battery damage and improving charging reliability. Flexible operation modes: Three selectable modes let you choose normally open mode, pure light control mode, or light control plus timing mode to match different installation needs. Smarter discharge management: Discharge control uses battery discharge rate characteristics to regulate output precisely, helping maintain battery performance and prolong useful service life. Main functions and performance Battery status display: Visual LED feedback for quick diagnostics and monitoring. Charging protection: Advanced circuitry guards against overcharging, short circuits, and incorrect polarity connections while optimizing charging efficiency. Mode selection: Easily switch between normally open, lightcontrolled, and lightcontrolled with timing, allowing tailored behavior for lighting and timing applications. Discharge regulation: Adaptive control based on battery discharge behavior to reduce deep discharge and balance load demand. Compatibility and applications Designed for systems that require controlled charging and discharge and lightcontrol functions. Typical use scenarios: Solarpowered outdoor lighting where lightactivated control and timed operation are required. Offgrid battery lighting and small power installations that need reliable charge protection and managed discharge. Backup lighting or equipment circuits that benefit from selectable operation modes and clear battery status indication. What makes it stand out Combines realtime status indication, multiple operation modes, and precise discharge control in a single unit. Focuses on reliable charging behavior and adaptable control options to fit a range of batterypowered lighting and small power setups. Specifications to confirm before installation Verify compatibility with your battery type, voltage, and system wiring. Use appropriate wiring and fuses according to your system requirements. This product is intended for users who need straightforward battery monitoring, configurable light control, and controlled charging and discharging without adding complex equipment.
