P2 Upper Limit The voltage where the relay switches state (e.g., 14.4V). P3 Timer (Optional) Sets a delay in minutes before the relay kicks in. 4. Calibration If the voltage on the screen doesn't match your multimeter: Hold the SET and + buttons simultaneously.
Some boards drift in timing accuracy. To recalibrate: Leave a comment below with your "welding voltage,
The relay remains permanently open and passive. The board operates purely as a discrete digital voltmeter panel.
The XH-M608 features a straightforward design, with input, battery, and relay connections clearly marked on the circuit board. Input Power ( VINcap V sub cap I cap N end-sub VINcap V sub cap I cap N end-sub P3 Timer (Optional) Sets a delay in minutes
Protect a 24V battery from being drained too low by a load (inverter/motor). Setup: U₁ (lower) = 22V, U₂ (upper) = 24V.
If your settings become corrupted or the module behaves erratically, you can trigger a hardware factory reset: Voltage Protection Board XH-M608 - Make Electronics
