Tired of coming back to a dead battery after your car’s been sitting awhile? This Cllena remote battery kill switch is here to help! It’s a smart 12V disconnect switch rated at 240A (with a 500A instantaneous peak) that lets you cut power remotely to prevent battery drain from things like old wiring, forgotten lights, or long-term parking. It features a handy LED display that shows your battery’s real-time voltage, so you always know its condition. The switch automatically cuts power when voltage drops below 11.8V (after a 120-second delay) to save your battery, and it disables the remote above 13.2V to avoid accidental shut-offs while driving. You can control it from up to 100 meters away with the included remote, or manually with the button on the unit. Installation is straightforward—just connect it to the negative terminal (fits 9–17mm posts). Perfect for cars, trucks, RVs, boats, ATVs, and more. A must-have for anyone who wants to protect their battery, boost its lifespan, and add an extra layer of anti-theft security!
