Andetongrson Remote Battery Disconnect Switch 240A 12V/24V with LED Voltage Display and Dual Remotes

The Andetongrson Remote Battery Disconnect Switch instantly cuts vehicle power with remote control, shows real-time voltage on an LED screen, and includes a full hardware kit for easy 12V/24V installation.

When you need a reliable way to prevent battery drain, protect against theft, or safely isolate electrical systems, this 240A remote battery kill switch is built for everyday vehicles and recreational rigs. The unit combines a bright LED voltage readout, weather-resistant housing, and dual remote fobs so you can cut power from inside the cabin or from a distance. Everything necessary for mounting and wiring is included for a straightforward, tool-friendly install.

How will this switch protect my vehicle from theft and battery drain?

The switch severs the main battery feed instantly when activated, stopping all accessory power and disabling hotwiring attempts. Because it physically disconnects the battery, unauthorized users cannot energize the vehicle’s electrical systems.

• Remote cut-off with two key fobs for convenience and backup
• Complete power isolation prevents parasitic drain during storage
• Flame-retardant ABS housing reduces risk near engine heat
• Gold-plated copper terminals for reliable long-term contact

Will this handle my vehicle’s starting current and voltage needs?

Yes — the Andetongrson switch supports both 12V and 24V systems and is rated for 240A continuous current with a 500A one-second peak surge. That peak rating accommodates typical engine cranking currents for most cars, SUVs, light trucks, RVs, and ATVs.

• Continuous rating: 240A; peak surge: 500A (1 second)
• Compatible with 12V and 24V battery systems
• Not intended for heavy construction engines exceeding 600A starting draw
• Side- and top-post adapters included for broad battery compatibility

How easy is installation and what accessories are provided?

The kit arrives ready to mount: thick 10AWG wiring, terminal clamps, mounting brackets, and the necessary hand tools are included so you can set it up without specialty parts. The compact module can be fixed under the hood, on the firewall, or inside the cab depending on your preferred wiring route.

• All-inclusive kit: two remotes, wiring, clamps, brackets, and tools
• Tool-free terminal clamping and foam adhesive pads for secure mounting
• Clear printed instructions for top-post and side-post batteries
• LED display wired to show real-time battery voltage (±0.5V accuracy)

What environmental conditions and durability features does it have?

The housing is made of reinforced, flame-retardant ABS and the electrical contacts are gold-plated copper to resist corrosion and retain conductivity. The design tolerates wide temperature ranges and road or marine exposure for everyday reliability.

• Reinforced ABS case resists heat, dust, and moisture
• Gold-plated copper terminals reduce oxidation and ensure contact
• Operates reliably from -22°F to 194°F (-30°C to 90°C)
• Rated for on-road, off-road, RV, and marine recreational use

Who this is for: drivers and vehicle owners who store vehicles for extended periods, want an added anti-theft layer, or need a convenient way to isolate the battery during maintenance. It suits everyday cars, SUVs, light trucks, RVs, ATVs, and small boats where a compact, easy-to-install, and robust battery disconnect solution is desirable. If your application requires very high cranking currents beyond the 500A peak rating, consider a heavy-duty commercial starter relay instead.
