Smart Remote Control Car Kill Switch

Protect and Extend Your Battery’s Lifespan

Tired of dead batteries after parking too long or forgetting your lights? This 12V Remote Battery Disconnect Switch automatically cuts power when voltage drops, protecting your battery and helping you avoid costly replacements.

Installed directly on the negative terminal, the device monitors battery voltage in real time. When voltage falls below 11.8V, it cuts off power after 120 seconds to prevent deep discharge. When voltage rises above 13.2V (engine running), the remote function is disabled to avoid accidental shut-off while driving.

Benefits

• Automatic Power Cutoff at Low Voltage: Prevents unexpected battery drain by automatically disconnecting power when voltage drops below 11.8V – perfect for long-term parking or infrequently used vehicles.
• Protects Battery Life and Electronics: Stops hidden power loss caused by aging wiring, forgotten lights, or standby electronics, extending battery lifespan and reducing repair costs.
• Remote Control Convenience: Wirelessly turn battery power on or off from up to 30 meters away. No need to open the hood – ideal for storage, emergencies, or quick shutdown.
• Quick, Hassle-Free Installation: Compact design installs directly on the negative terminal. No programming, coding, or software required – ready to use in minutes.
