Description
The XH-M604 is a digital battery charge control and protection module designed for DC 6V–60V battery systems. It is widely used in lithium-ion, LiFePO₄, and lead-acid battery charging setups to automatically control charging by cutting OFF the charger when the battery reaches a preset voltage and reconnecting it when the voltage drops.
It is commonly used in solar systems, battery backup systems, DIY power banks, UPS-style setups, and energy storage projects.
Key Features
• Wide input range DC 6–60V (up to ~80V max)
• Digital LED display for real-time battery voltage monitoring
• Programmable charge start and stop voltage settings
• Automatic relay control to connect/disconnect the charging circuit
• Prevents overcharging and extends battery life
• Suitable for Li-ion, LiFePO₄, and lead-acid batteries
• High-precision voltage control (±0.1V typical)
• Built-in push-button interface for easy setup
• Compact PCB module for embedded installations
• Memory retention of settings after power loss (in most versions)
