Product description
Nilight Remote Battery Disconnect Switch
Remote Control 12V 250A Car Anti-Theft Kill Switches
- Electrical Specifications:
- Volts: 12V (compatible with 11-15V voltage range, adapting to slight fluctuations in vehicle battery voltage)
- Working Current: 250A (high-current design to meet the power needs of heavy-duty vehicles and high-power accessories)
- Environmental Adaptability: Working Temperature: 40℃-85℃, able to withstand high-temperature environments (such as engine compartments in summer) and low-temperature conditions (such as cold winters), ensuring stable operation in diverse climates.
- Material Quality: Adopts a nylon flame-retardant shell (prevents fire risks caused by overheating or short circuits) with a pure copper inner core; the internal coil is also made of pure copper—combining safety, durability, and excellent electrical conductivity.
- Package Contents: 1 × 250 amp remote battery disconnect switch, 2 × remote controls, 1 × red insulating sleeve (for safe wiring and preventing electric shock), 1 × metal clamp (for firm installation on the vehicle), 2 × flat copper sheets (enhances current transmission efficiency), 1 × terminal block (simplifies wire connection and ensures stable contact).
Product Features
- Wireless Remote Control: Features a wireless remote control design, equipped with two pre-paired remote fobs—no additional pairing steps are required, and they can be used immediately after unpacking. The remote control has a maximum effective range of 164 feet, allowing users to operate the switch from a distance (e.g., controlling battery disconnection without approaching the vehicle), which is convenient and practical.
- Heavy-Duty Current & Voltage Performance: Designed for 12V heavy-duty scenarios, with a rated working current of 250A—higher than standard switches, effectively enhancing reliability when powering high-demand equipment (such as winches, large LED light bars, or heavy-duty truck systems). It is widely suitable for cars, trucks, RVs, boats, and other 12V vehicles.
- High-Conductivity Copper Coil & Inner Core: The pure copper inner core and internal pure copper coil minimize current loss during transmission, ensuring efficient power supply; the nylon flame-retardant shell further protects the internal components from external damage and high temperatures, extending the product’s service life.
- Dual Practical Functions: Anti-Drain & Anti-Theft:
- Anti-drain: When the vehicle is not in use for a long time, the switch can disconnect the battery to prevent power loss caused by standby current of vehicle electronics (e.g., stereos, alarm systems).
- Anti-theft: As an anti-theft "kill switch," it cuts off the battery power supply via remote control, disabling the vehicle’s startup system—greatly reducing the risk of theft.
