XH-M601 12V Auto-Charging Board Intelligent Power Module

XH-M601 12V Intelligent Auto-Charging Board – Smart Power Management Module

The XH-M601 12V Intelligent Auto-Charging Board is a compact, reliable power management module designed for 12V battery charging systems. Featuring automatic relay-controlled charge switching and DC voltmeter detection, this board keeps your 12V battery at optimal charge — automatically closing the relay at 12.4V to begin charging and disconnecting at 14.8V to prevent overcharge. Perfect for DIY battery charger builds, solar systems, backup power setups, and embedded electronics projects.

Key Features

• Automatic Charge Control: Relay closes at 12.4V (charging begins) and disconnects at 14.8V (charging stops) for safe, hands-free battery management
• Adjustable Voltage Thresholds: RP1 and RP2 potentiometers allow fine-tuned calibration of relay switching voltages
• DC Voltmeter Detection: Accurate voltage monitoring ensures precise switching for consistent battery health
• Compact SMD Design: Small 50×32×18mm footprint (L×W×H) and lightweight at just 21.3g — ideal for space-constrained builds
• Wide Supply Voltage Range: Operates between 13.8V–14.8V supply voltage
• Customizable: Supports custom configuration for a variety of 12V battery charger applications

Frequently Asked Questions

Q: What does the XH-M601 auto-charging board do?

A: The XH-M601 is an intelligent 12V battery charging control module. It automatically activates your charger when battery voltage drops to 12.4V and cuts off charging when voltage reaches 14.8V, preventing overcharge and keeping your 12V battery in optimal condition without manual intervention.

Q: Can I adjust the relay switching voltages on the XH-M601?

A: Yes. The board includes two adjustable potentiometers — RP1 and RP2 — that allow you to carefully fine-tune the relay closing (charge start) and relay disconnect (charge stop) voltage thresholds to suit your specific 12V battery type and application.

Q: What kinds of projects is the XH-M601 suitable for?

A: The XH-M601 is ideal for DIY 12V battery charger projects, solar power storage systems, backup power management setups, automotive battery maintenance systems, and any embedded electronics project that requires automatic, relay-controlled voltage management for a 12V battery.

Q: How compact is the XH-M601 module?

A: The XH-M601 has a very compact footprint of 50×32×18mm and weighs just 21.3g, making it easy to integrate into tight enclosures and space-constrained DIY builds.
