Suitable for batteries within the 6-40V range. Output Type: Relay switch (isolated from control circuit). Dimensions: Approximately Menu Functions ( )
Press SET while on a parameter to view its current value, then use ADD/DEC to change it. Long-press ADD/DEC for rapid adjustment. Range / Modes P0 Working Mode U
. If the voltage is too low, the module will not power up or trigger the relay. If you were looking for information on the HP LaserJet Enterprise M608 printer , common tasks include: Printing Configuration Pages: Swipe right to Configuration/Status Pages Configuration Page Resetting:
The display flashes. Use '+' or '-' to set the voltage at which the charger should turn OFF. Wait 3 seconds: The setting will save. C. Parameter Functionality (P0-P3 Settings) Xh-m608 Manual
In this mode, the module acts as an automatic battery charger switch.
I assumed typical amplifier-module behavior. If you want the precise XH-M608 manual (pinout, PCB silkscreen, full electrical specs, BOM, firmware if applicable), tell me which manufacturer or share a photo/link of your board and I’ll extract the exact pinout and instructions.
When the battery voltage is lower than the start voltage, the relay closes to begin charging. It opens once the battery reaches the full voltage limit. Discharge Mode (dn): Suitable for batteries within the 6-40V range
If the reading is inaccurate, many modules allow calibration by holding specific buttons during power-on to adjust the display to match a multimeter reading .
Protip from the trenches: If your relay isn't clicking, reverse your logic. Send a HIGH signal. If it clicks, your version is active-high. You’ve just reverse-engineered the manual’s biggest lie.
To protect a battery from completely draining while powering devices like inverters or DC motors: Long-press ADD/DEC for rapid adjustment
This occurs when your voltage thresholds are set too close together, or your battery has high internal resistance. When the load turns off, a weak battery's voltage naturally "rebounds" upward. If it rebounds past your activation threshold, the module turns the load back on immediately, causing a rapid on/off loop. To fix this, widen the gap between your P1 and P2 values. Can I use this to control a 120V/240V AC Charger?

The relay is usually rated for 10A . If you are running a heavy motor or a large inverter, use the XH-M608 to trigger a larger external contactor.
