XH-M604 Battery Charging Control Module with Voltage Protection & LED Display
The XH-M604 Battery Charging Control Module with Voltage Protection & LED Display is a sophisticated and reliable solution for managing the charging process of batteries ranging from 6V to 60V. Engineered to support both lithium and lead-acid batteries, this module ensures optimal battery performance and longevity by providing precise control over the charging cycle. Its versatility and ease of use make it an essential component for hobbyists, engineers, and professionals working on battery-powered systems.
The core functionality of the XH-M604 lies in its ability to allow users to set specific starting and stopping voltages for the charging process. This feature is critical for preventing overcharging, which can significantly reduce battery lifespan, and undercharging, which can affect performance. By automating the charging cycle, the module activates the charging circuit when the battery voltage falls below the set starting voltage and disconnects it when the voltage reaches the stopping threshold. This automation eliminates the need for constant monitoring, making it ideal for unattended charging scenarios such as in renewable energy systems.
Features:
- Numerical control for precise setting of charging voltages.
- Supports input voltages from DC 6V to 60V (up to 80V max).
- Three-digit red LED display with 0.1V precision for easy monitoring.
- On-board momentary push buttons for setting start and stop voltages.
- Automatic charging control to prevent overcharging and undercharging.
