Click. Isolate. Never Wake Up to a Dead Battery Again.
You turn the key, and the only sound is a tired click—or worse, silence. Parasitic drains, forgotten lights, and that old amplifier have been bleeding your battery dry all night. This remote kill switch puts total control on your keychain. One press cuts all power to the vehicle, locking in your battery’s charge for weeks, not hours. The bright LED voltage display on the control unit gives you a real-time health check of your battery, so you’re never caught off guard. Stop disconnecting terminals in the cold. Stop jumping your car every Monday morning. Just click, isolate, and know your rig is ready to fire when you are.
True Remote Isolation – No Hood Pops, No Tools
With the included wireless key fobs, you can completely disconnect your battery from inside the house, the driver's seat, or across the parking lot. The heavy-duty 240-amp relay handles the full electrical load of your vehicle, cutting off all circuits to prevent slow drains from computers, alarms, and accessories. When you’re ready to drive, click again and full power is restored instantly. It’s the ultimate anti-theft and battery-saving measure in one device.
Built-In LED Voltage Display – Know Your Battery’s Heartbeat
Stop guessing if your alternator is charging or if your battery is about to fail. The control unit features a clear LED display that shows real-time voltage whether the switch is on or off. Monitor your battery’s health at a glance, catch weak cells before they ruin a trip, and verify your charging system is working properly. It’s peace of mind, hardwired into your dash or engine bay.
240-Amp Continuous Duty – Built for Trucks, RVs, and More
This isn’t a flimsy relay meant for a light bar. It’s rated for 240 amps continuous and 500 amps surge, making it safe for high-demand vehicles like diesel trucks, motorhomes, boats, and car trailers. The weather-sealed housing and stainless-steel terminals resist corrosion, vibration, and temperature swings. Install it once, and it’ll outlast your next three batteries.

240A High-Capacity Relay
Safely handles the full electrical load of most cars, trucks, and RVs.

Install in Minutes. No Special Tools. Total Power Control.
Just connect the relay, mount the control unit, and you're done. No cutting. No soldering. No expensive mechanic. Once it's wired in, your remote fob becomes the master switch for your entire battery. One click kills every drain. One click locks in your charge. Say goodbye to dead mornings—this is power mode: off. Savings mode: on.
Auto-Guard: Never Drain Below 11.8V.
Your battery has a danger zone, and our switch refuses to let it cross that line. When voltage dips to 11.8V, power cuts automatically—protecting your battery from deep discharge and preserving enough charge to start. No monitoring. No stress. Just a battery that's always ready when you are.

Daily Drivers with Parasitic Draws
Audio systems, alarm setups, and older vehicles that slowly drain.
Perfect for Every Vehicle That Sits Too Long
What Wire-Savvy Drivers Are Saying
-
Solved my phantom drain overnight
My old F-250 has a slow draw somewhere that would kill the battery in three days. Now I click the remote when I park, and the LED shows 12.6 volts every time. Best $40 I’ve spent under the hood.
-
Perfect for my boat’s dual batteries
I installed this on my saltwater fishing boat. The remote lets me disconnect while the cover is still on, and the voltage display tells me if my solar panel is keeping things topped up. No more climbing in to check.
-
Great anti-theft layer for my classic car
My ’68 Mustang has no computer, but now it has a hidden kill switch that I control from my house. If I forget to disconnect, I just check the voltage LED by the grill. Genius piece of kit.
-
Handles my diesel without breaking a sweat
I was worried about the current draw from my dual-battery Ram. This relay is huge and doesn’t even get warm. The LED display is bright and easy to read. I’m ordering another for my work van.
