For long-term use, consider placing the module in a ventilated enclosure to manage any heat generated during relay operation. Calibration:
Connect to the positive terminal of the battery you wish to monitor.
The module requires a minimum of 6V on the input ( Vin ) terminals to power up its internal microprocessor. Check your power source or battery voltage with a multimeter to ensure it outputs at least 6V DC. Check for loose wire strands shorting the terminals. The relay clicks repeatedly ("chattering"). Xh-m608 Manual
Located at the base of the board for secure wiring connections. Parameter Functions Explained
The menu dictates the logic governing how the relay reacts to voltage variations. Long-press or short-press SET when highlighting P0 to change its underlying value: For long-term use, consider placing the module in
Use this architecture when you want to terminate an incoming charging current (such as from an AC-to-DC wall charger, solar charge controller, or wind turbine) once the battery hits its maximum capacity ceiling.
The XH-M608 utilizes a three-button interface: , + (Up) , and - (Down) . Entering the Menu Check your power source or battery voltage with
The relay stays closed to power your load until the battery hits the undervoltage limit. 3. Programming & Modes
DC 6V – 60V (Commonly used for 12V and 24V batteries) Control Accuracy: 0.1V Output Type: Direct Output / Relay Switch Output Voltage Error: ±0.1V
The is a versatile digital battery charge and discharge control module designed to safeguard DC 6–40V battery systems. It features an integrated voltmeter and a programmable relay to prevent overcharging or over-discharging by automatically connecting or disconnecting power based on set voltage thresholds. 1.
