More features

• Auto-Voltage Detection for 12V & 24V Systems: This intelligent battery disconnect switch automatically detects and adapts to 12V/24V electrical systems—no manual setting required. It provides a universal power management solution for cars, RVs, trucks, and boats. After switching voltage modes, simply power off and restart to restore the selected mode
• Intelligent Anti-Misoperation Protection for Driving Safety: Equipped with a built-in safety mechanism, the remote control function is temporarily disabled during engine cranking or when abnormal voltage (below 11.8V/23V or above 13.2V/25V) is detected. The indicator light turns on to alert you, effectively preventing accidental power-off while driving. Manual operation via the physical button remains available at all times
• Comprehensive Battery Protection & Extended Lifespan: In smart mode, the system continuously monitors battery voltage and automatically disconnects power when it detects prolonged low-voltage conditions (below 11.8V for over 2 minutes). This prevents deep discharge during long-term parking, protecting your battery from damage and significantly extending its service life. Ideal for preventing power drain caused by forgotten lights or standby electronics
• Quick & Tool-Free Installation: Comes with battery clamps and connection studs, allowing easy setup without cutting or modifying your vehicle’s original wiring. Please ensure power is off before installation and perform an ignition test after setup to verify proper function
• Real-Time Voltage Visual Alerts: Built-in indicator lights and alarms provide instant feedback on battery condition. When voltage drops below 11.8V/23V, the “Low” indicator lights up and an alarm sounds after 60 seconds. Normal voltage keeps the “Mid” light on, while overvoltage (above 13.3V/25V) activates the “High” light—helping you monitor your battery health at a glance
