The XH-M604 Battery Charge Control Module is an intelligent, programmable solution designed to automate the charging process for a wide range of battery types. Compatible with voltages from 6V to 60V, this module acts as a precision digital switch that connects your charger to your battery when the voltage is low and automatically cuts the circuit once the battery reaching a full charge.
This module is essential for preventing overcharging, which significantly extends the lifespan of Lead-Acid, Lithium-Ion, and Polymer batteries. Its bright LED display provides real-time voltage monitoring, making it an ideal choice for solar power systems, electric vehicle charging, and industrial backup power banks.
Key Features
  • Universal Battery Compatibility: Supports 12V, 24V, 36V, and 48V systems, including Lead-Acid, Lithium, and Iron-Lithium batteries.
  • Programmable Thresholds: Users can precisely set both the “Start Charging” voltage and the “Stop Charging” voltage to match specific battery chemistries.
  • Automatic Cut-off: High-quality onboard relay automatically disconnects the charger to prevent overcharging and battery swelling.
  • Real-Time Voltage Display: Integrated 3-digit LED tube provides instant feedback on the current battery voltage with 0.1V accuracy.
  • Industrial Reliability: Built with high-current terminals and a durable PCB, suitable for 24/7 automated charging environments.
  • Power-Fail Memory: Internal storage retains your custom voltage settings even if the power is completely disconnected.
Usage Guidelines
  1. Wiring: Connect the Charger to the input terminals and the Battery to the output terminals. (Ensure the charger voltage matches the battery’s requirements).
  2. Setting Start Voltage (Low Limit): Press and hold the Left Button (Start) for 3 seconds until the display flashes. Use the buttons to set your desired lower threshold (e.g., 12.0V).
  3. Setting Stop Voltage (High Limit): Press and hold the Right Button (Stop) for 3 seconds until the display flashes. Use the buttons to set your desired full-charge threshold (e.g., 14.4V).
  4. Operation: The module will automatically turn on the charger when the battery drops to the Start Voltage and turn it off when it hits the Stop Voltage.
  5. Factory Reset: While the device is powered on, press the Start and Stop buttons simultaneously until the display shows “888”.
Q: Can this module step down or regulate the voltage from my charger?

No. This is a Control Module, not a voltage converter. Your charger must already provide the correct voltage for your battery. The module simply acts as a smart switch between the two.

Q: Can I use this with a Solar Panel?

Yes, provided you have a solar charge controller or a regulated DC source. The XH-M604 is excellent for managing the final “Cut-off” point in DIY solar setups.

Q: Does it work with 48V Lithium-ion packs?

Yes. Since the module supports up to 60V, it is fully compatible with 48V systems (which typically reach 54.6V or 58.4V when fully charged).

Q: Why does the relay "click" rapidly?

This usually happens if the “Start” and “Stop” voltages are set too close to each other. Ensure there is a sufficient gap (at least 1V to 2V) to account for the battery voltage “rebound” after the charger is disconnected.

Q: Is this suitable for commercial fleet charging or business use?

Absolutely. Business purchasers frequently use the XH-M604 in warehouse AGVs (Automated Guided Vehicles), backup UPS systems, and telecom stations to automate battery maintenance without manual supervision.

Q: My display shows "Err". What is wrong?

Ensure the battery is connected first. The module is powered by the battery it is monitoring. If the battery voltage is below 6V, the module may not power on or function correctly.
