Wireless Remote Control Car Isolator Switch, 12V 240A Battery Disconnect, Energy Saving Anti Theft with 2 Remotes for Car, RV, ATV, Truck, Camper, Boat

Energy-Saving & Anti-Theft Protection：This wireless remote control battery disconnect switch operates at 12V/240A, consuming only 3mA standby current. It automatically shuts down at a threshold of 11.9V±0.2V to prevent battery drain, ensure security, and simplify vehicle electrical system maintenance. Effectively protects and extends your car battery's lifespan. Smart Auto Power Cut-Off: The switch intelligently cuts power within 180 seconds when battery voltage drops below 11.9V to conserve energy. Safety lockout activates (panel protection indicator lights up) if voltage exceeds 13.2V, preventing accidental shutdowns during driving. Dual safeguards maximise battery longevity. Easy Installation: No need to open the bonnet repeatedly – this 12V isolator saves time with remote operation. Important: Ensure full power-off before installation and perform an ignition test afterward. Compatible with standard negative terminal sizes: 9-13mm & 15-17mm. Durable & High-Performance Design: Built with corrosion-resistant materials and pure copper wiring for optimal conductivity. Handles 500A surge currents and operates reliably from -22°F to 194°F. Ultra-low 3mA standby consumption ensures long-term reliability. Compatibility Notice: Designed for 12V systems with engine displacement UNDER 4.0L ONLY. Not for large trucks, diesel engines >4.0L, or start-stop vehicles. Features leakage display panel (Low: 0.5-2A; Mid: 2-5A; High: >5A) for diagnostics. Ideal for cars, RVs, ATVs, campers, boats within limit.
