The XH-M608 utilizes a structured sub-menu system ( P0 through P3 ) to define exactly how the hardware handles your batteries.
For long-term use, consider placing the module in a ventilated enclosure to manage any heat generated during relay operation. Calibration:
Lead-acid, Lithium-ion, LiFePO4, Gel, and AGM batteries Physical Dimensions: 81mm x 54mm x 18mm Board Layout and Interface
Decreases numerical values and can trigger calibration mode. Xh-m608 Manual
Increase the difference between the lower (U₁) and upper (U₂) voltage settings to prevent "chattering" (rapid on/off cycles). 6. Important Safety Warnings
When the battery is low, the relay closes to allow the charger to work. When full, it opens to prevent overcharging.
Direct output (voltage passes through the relay) Voltage Error: ±0.1V The XH-M608 utilizes a structured sub-menu system (
Connect your charger or load here. The relay acts as a switch based on your voltage settings. 3. Menu Navigation (The "P" Settings) To enter the menu, short press SET to cycle through modes:
The module continuously monitors the voltage at its VIN terminals and compares it against user-programmed thresholds (P1 = lower limit, P2 = upper limit). Based on the selected mode (P0), it controls the relay state to either connect or disconnect a charger or load.
Use ADD or DEC to cycle through P0 to P3 . Increase the difference between the lower (U₁) and
: Decreases voltage parameters or activates manual control features. Operation Modes
: Connects to the system's power source or battery to power the board itself.
: The relay is off by default and will turn on when the voltage drops below the P1 lower limit. It will remain on until the voltage rises above the P2 upper limit, at which point it turns off . This creates a "charge me" signal.
The relay closes when the voltage drops to P1 and opens when it rises to P2 .
The is an all-in-one digital battery charge and discharge control module. It acts as an intelligent switch, automatically connecting or disconnecting a charger or load based on real-time voltage readings.
