XH-M604 Charge Control Module DC 6-60V

The XH-M604 is a programmable battery charging control module designed to automate and protect the charging process for lead-acid, lithium-ion, and other 6-60V battery types. Rather than manually monitoring a charger and disconnecting it once the battery is full, this module lets you set both a start-charging voltage and a stop-charging voltage, then handles the switching automatically. Once the battery reaches your defined stop voltage, the module cuts the charging circuit on its own, preventing overcharging and helping extend overall battery lifespan without any manual intervention.

A 3-digit red LED display shows real-time voltage readings, while onboard momentary push buttons let you quickly program both the start and stop thresholds in precise 0.1V increments, with a tight ±0.1V voltage tolerance for reliable, repeatable switching. A built-in factory reset function makes it easy to restore default settings if you need to reconfigure the module for a different battery setup. Since the module uses direct output switching, it drops cleanly into existing charging circuits without adding conversion losses.

This makes the XH-M604 a practical fit for solar panel charge controllers, wind turbine charging systems, household DC battery chargers, off-grid and remote power installations, backup power and UPS systems, and general battery maintenance or float-charge setups. It’s a straightforward, low-cost way for hobbyists and engineers to add automated overcharge protection to almost any DC battery charging system.
