XH-M602 & XH-M633 Battery Charging Control Modules – Digital Overcharge Protection for 12V-24V/48V Systems

XH-M602 (The 24V Specialist)

The XH-M602 is specifically optimized for 12V and 24V systems. It is the go-to module for standard lead-acid batteries and 7S/8S Lithium packs. It features an integrated 20A relay, making it ideal for standard residential solar setups or home power backup systems where you need to protect your battery bank from the fluctuations of a solar charger.

XH-M633 (The High-Voltage Versatile)

The XH-M633 offers a broader range, supporting systems up to 48V. This makes it perfect for E-bike battery packs or more advanced industrial solar arrays. It is slightly more compact and designed for systems where you need to monitor higher voltage tiers with precision.

Common Key Features ✨

• Programmable Limits: Set your own “Start” and “Stop” voltages with the simple onboard button interface.

• Auto-Cutoff: Protects your investment by cutting the connection as soon as the battery hits your defined “full” threshold.

• Digital Accuracy: Displays voltage in real-time, replacing the need for an external multimeter.

• Power-Off Memory: Your programmed settings are saved in the module’s non-volatile memory, even if the power goes out.
