Andetongrson Remote Battery Disconnect Switch with LED Voltage Meter — 12V/24V 240A, Flame‑Retardant Housing, Dual Remotes

The Andetongrson remote battery disconnect switch instantly cuts vehicle power, shows real-time voltage on an LED readout, and stops battery drain or unauthorized use.

This compact, heavy-duty battery kill switch combines remote control convenience with a built-in LED voltage meter and flame-retardant housing, designed for 12V and 24V automotive systems. Rated for 240A continuous and 500A peak surge, the kit includes two remotes, mounting hardware, thick 10AWG wiring, and adapters for both top-post and side-post batteries. The weather-resistant ABS enclosure, gold-plated terminals, and complete accessory package make it suitable for cars, trucks, RVs, ATVs and marine craft where reliable power isolation and theft deterrence matter.

How does this switch improve vehicle security and prevent battery drain?

By severing the battery’s connection to the vehicle with a remote or manual switch, this unit prevents parasitic draws and disables electrical systems to deter hot-wiring and unauthorized starts. The remote functionality means you can cut power before leaving or from a short distance for extra convenience.

• Dual remote controls for instant off/on from outside the vehicle
• Complete isolation eliminates accessory and draw currents
• Flame-retardant housing reduces fire risk in harsh conditions
• Side-post and top-post adapters included for widespread fitment

Will it work with my 12V or 24V vehicle and handle engine starts?

The switch is compatible with standard 12V and 24V DC systems and supports typical automotive starting currents thanks to its 240A continuous rating and 500A one-second surge capacity. It’s suitable for most passenger vehicles, SUVs, RVs and light trucks, but not for very high-start-current heavy equipment.

• Operates on both 12V and 24V systems without modifications
• 240A continuous, 500A peak surge (1 second) handles common starter draws
• Not recommended for engines requiring >600A starting current
• Gold-plated copper terminals reduce resistive heating at high loads

How easy is installation and what accessories are included?

Installation is tool-friendly and doesn’t need electrical system alterations: the kit arrives with everything required to mount and wire the main unit. Clear instructions and included hardware make it a straightforward DIY job for most vehicle owners.

• Includes mounting brackets, adhesive pads, wrench and hex key
• Thick 10AWG wiring and heavy-duty terminal clamps supplied
• Side terminal adapter brackets for side-post batteries included
• Compact main unit fits under hood, on firewall, or inside cabin

What does the LED voltage display show and why is it helpful?

The integrated LED voltmeter provides a precise live readout (±0.5V) so you can spot low-voltage conditions or charging problems before they cause a no-start. Monitoring battery voltage at a glance helps plan charging and prevents deep discharge during long storage.

• LED readout gives continuous battery voltage monitoring
• Accuracy within ±0.5V for reliable status checks
• Useful for off-grid, seasonal storage, or boat/RV battery care
• Shows when battery is disconnected or under load

Who is this for: the Andetongrson remote battery disconnect switch is aimed at vehicle owners who need dependable battery isolation and theft deterrence without complex wiring or expensive installation. It’s ideal for private cars, weekend campers, RVs, ATVs, small commercial trucks and boat owners who want a rugged, all-inclusive solution to prevent parasitic drain, simplify winter storage, and secure their vehicle against unauthorized use.
