XH-M609 DC 12V–36V Lithium Battery Charger and Over-Discharge Protection Module with Digital Display

The XH-M609 DC 12V–36V Lithium Battery Charger Module is an intelligent lithium battery charging and protection solution designed to prevent over-charging and over-discharging of battery packs. Featuring an onboard digital voltage display, this module automatically cuts off the load when the battery voltage drops below the set value and reconnects when voltage is restored.

Ideal for DIY battery chargers, solar battery systems, UPS backups, robotics, and EV projects, the XH-M609 supports a wide DC input range of 12V to 36V, making it highly versatile for multiple lithium battery configurations. The module is easy to configure using onboard buttons and offers reliable protection to extend battery life.
