The module uses a menu system (P0 to P3) to define its behavior. Use the button to navigate and the + / – buttons to adjust values. P0: Operating Mode Selection
Integrated voltmeter, undervoltage/overvoltage protection, and a timing discharge function. 2. Wiring Guide
Understanding the limits of your hardware is critical for preventing electrical failure. DC 6V to 40V. Display & Control Accuracy: 0.1V. Xh-m608 Manual
The relay does not function; it only displays the current voltage.
Connect the positive (+) and negative (–) leads of your 6-40V battery to the module's battery input terminals. The module uses a menu system (P0 to
The relay stays closed to power your load until the battery hits the undervoltage limit. 3. Programming & Modes
Sets the trigger for starting a charge or stopping a discharge. Display & Control Accuracy: 0
The relay on the board should be placed "in-line" with one of the wires (typically the positive) of your charger or load.
Relay closes when voltage ≤ P1 (lower limit) and opens when voltage ≥ P2 (upper limit).
Relay stays closed only when the voltage is between the lower (P1) and upper (P2) limits.
