    SE9018 1A Solar USB MPPT Lithium Battery Charging Module Constant Voltage & Current Charging

    RBD-3866

    The SE9018 Solar MPPT Charging Module is a high-performance constant-current / constant-voltage lithium battery charging board designed for single-cell Li-ion or LiPo batteries.
    It integrates MPPT (Maximum Power Point Tracking) technology for efficient solar charging and supports both USB and solar panel input (DC 4.5–6V).

    Using an internal PMOSFET architecture, the SE9018 eliminates the need for external protection diodes while providing reverse-charge protection, thermal regulation, and automatic current adjustment to ensure safe, efficient battery charging in all conditions.
