Manual - Xh-m608

Start charging when the battery is low; stop when it's full.

The (also known as HCW-M631) is a versatile DC 6-40V battery charge/discharge module featuring high-precision voltage monitoring and programmable protection thresholds. Key Specifications Input Voltage Range: DC 6-40V. Voltage Accuracy: ±0.1V. Xh-m608 Manual

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: Start charging when the battery is low; stop when it's full

Example: | Problem | Possible cause | Solution | |-----------------------------|-------------------------------------|-----------------------------------| | No display | Power supply issue / reverse polarity | Check voltage, correct wiring | | Erratic temperature reading | Wrong sensor type / bad connection | Use NTC 10K 3950, check terminals | | Relay does not switch | Incorrect mode (P2) or hysteresis | Set P2 to H or C, adjust P1 | | Temperature overshoot | Hysteresis too high / sensor placement | Reduce P1, move sensor closer to load | Voltage Accuracy: ±0

Used to calibrate the onboard voltmeter if it differs from a multimeter. Basic Operation

Controls discharge timing, which is useful for capacity testing or specific power-down sequences. Key Technical Specifications Specification Input Voltage Range DC 6V – 40V Voltage Error Control Accuracy Output Type
