XH-M601 12V Battery Charge Control Board – Auto Switch Module

XH-M601 Smart Battery Charging Control Board – Automatic Switch & Overcharge Protection

Keep your 12V batteries healthy and fully protected with the XH-M601 Smart Charger Power Control Board. This high-accuracy module automatically manages the entire charging cycle — starting and stopping charging at precise voltage thresholds — so you never have to worry about overcharging or deep discharge damage again. Ideal for hobbyists, DIY electronics enthusiasts, solar setups, automotive applications, and more.

Made in Mainland China.

Why Choose the XH-M601?

• Fully Automatic Charging Management: The board monitors battery voltage continuously. When voltage drops to ~12.4V (adjustable), it automatically closes the relay to begin charging. When the battery reaches ~14.8V (adjustable), it disconnects to prevent overcharging.
• High Precision Voltage Detection: Uses a DC voltmeter for accurate monitoring with a voltage error of only ±0.1V — reliable and consistent every time.
• Easy-to-Read Status Indicator: A red LED lights up during charging and switches off when the battery is full — no guesswork required.
• Energy Saving Design: The built-in relay disconnects the 220V input when charging is complete, saving power and adding an extra layer of safety.
• Adjustable Voltage Thresholds: Two onboard potentiometers (RP1 & RP2) let you fine-tune the start and stop voltages to suit your specific battery and application needs.
• Compact Module Format: Easy to integrate into existing charging setups or custom electronics projects.

Frequently Asked Questions

Q: What type of batteries is the XH-M601 charging control board compatible with?

A: The XH-M601 is designed for 12V lead-acid batteries, including standard car, solar, and deep-cycle batteries. It monitors and manages the charging process by automatically switching the charger on at ~12.4V and off at ~14.8V, both of which are adjustable via the onboard potentiometers.

Q: Can I adjust the charging voltage thresholds on the XH-M601?

A: Yes! The board features two potentiometers — RP1 for setting the low-voltage (start charging) threshold and RP2 for setting the cutoff (stop charging) voltage. Simply turn the potentiometers clockwise to increase the voltage or counterclockwise to decrease it, allowing you to customize the settings for your specific battery requirements.

Q: How do I know when my battery is fully charged using this module?

A: The XH-M601 features a built-in red LED indicator. The LED remains lit while the battery is charging. Once the battery reaches the cutoff voltage (~14.8V by default), the LED turns off and the relay disconnects the charger automatically — giving you a clear, visual confirmation that charging is complete.

Q: Is the XH-M601 safe to leave unattended while charging?

A: Yes, the board is designed for automatic, unattended operation. Its automatic cutoff function disconnects the 220V input once the battery is full, preventing overcharging and conserving energy. However, always follow standard electrical safety guidelines when working with mains voltage.
