Take Full Control of Your Vehicle's Power — From a Distance

The Smart Remote Battery Disconnect Switch is a reliable 12V/24V universal circuit breaker designed to protect your car, truck, or van battery from unnecessary drain. Whether you're storing your vehicle long-term, worried about parasitic power draw, or simply want an added layer of anti-theft protection, this master kill switch puts power control right in the palm of your hand — no tools needed once installed.

Made in Mainland China.

Key Features

Wide Compatibility: Works with 12V and 24V systems — perfect for cars, trucks, SUVs, RVs, boats, and more.
High Current Capacity: Rated at 240A continuous current with a peak instantaneous rating of 1000A for up to 30 seconds — handles even high-demand vehicles with ease.
Magnetic Latching Relay Technology: Uses an advanced magnetic relay for circuit control, drawing just 1mA (0.001A) on standby — virtually zero power consumption when idle.
Automatic Low-Voltage Cut-Off: If battery voltage drops below 11.8V, the switch automatically disconnects power after 120 seconds to prevent a dead battery.
Overvoltage Safety Lock: When voltage rises above 13.2V (i.e., while the engine is running), the remote is automatically disabled to prevent accidental shut-off while driving. The onboard button remains functional.
Includes 2 Remote Controls: Convenient wireless remotes let you engage or disengage the switch from outside the vehicle.
Easy Negative Terminal Installation: Connects via negative (ground) lead for stable performance and straightforward DIY installation. Always switch off all power before installing.
CE Certified: Independently tested and certified for safety and performance.

Frequently Asked Questions

Q: Is this battery disconnect switch compatible with both 12V and 24V vehicles?

A: Yes! The smart remote battery disconnect switch is fully compatible with both 12V and 24V electrical systems, making it suitable for passenger cars, trucks, SUVs, RVs, boats, and even heavy-duty commercial vehicles.

Q: Will the remote control accidentally shut off power while I'm driving?

A: No. When the vehicle is running and the alternator raises voltage above 13.2V, the remote control is automatically disabled to prevent any accidental power cut-off while driving. You can only control the switch via the physical button during this time.

Q: How does the automatic low-voltage cut-off work?

A: If your battery voltage drops below 11.8V (indicating a significantly depleted battery), the switch will automatically disconnect the power supply after a 120-second delay. This protects your battery from being fully drained and extends its overall lifespan.

Q: Is this difficult to install?

A: Installation is straightforward — the switch connects to the negative (ground) terminal of your battery. An instruction manual is included. Always ensure all vehicle power is turned off before beginning installation. If you are unsure, consult a qualified auto electrician.

Q: How much power does the switch draw when in standby mode?

A: Thanks to its magnetic latching relay technology, the standby current draw is just 1mA (0.001A) — virtually negligible and far lower than traditional disconnect switches.
