The XH-M609 lithium battery discharge control module is a programmable low voltage disconnect (LVD) relay module designed to protect batteries from over-discharge damage. This XH-M609 module monitors battery voltage in real-time and automatically disconnects the load when the voltage drops below a user-defined threshold, helping to extend battery lifespan and ensure reliable operation in DC power systems. The module operates across a wide voltage range of 7V to 80V DC, making it compatible with various battery chemistries including lithium, lead-acid, and other storage batteries.

The module features a clear three-digit LED digital display that shows the current battery voltage in real-time. Users can independently configure the cutoff voltage, the reconnection offset (the voltage increase required to reactivate the output), and a reconnection delay time ranging from 0 to 10 minutes. All settings are easily adjusted using the onboard push buttons, with automatic saving of configured values after the buttons are released. The module also includes a voltage calibration function, allowing users to fine-tune the displayed value to match a multimeter reading.

With a control precision of 0.1V and power consumption of less than 1.5W, this battery protection module is efficient and accurate. When the battery voltage reaches the configured cutoff threshold, the relay disconnects the load to prevent deep discharge. Once the battery voltage rises to the reconnection threshold (cutoff voltage plus offset), a timer starts, and if the voltage remains stable for the configured delay period, the output is automatically reconnected. This makes the XH-M609 ideal for solar power systems, battery backup systems, and any DC application where battery protection is essential.
