About this item

  • [12V Smart Battery Kill Switch for High-Efficiency Drain Prevention & Longevity] The Venquda car battery kill switch is engineered to eliminate battery drain from long-term parking, aging wiring, or accidental light/accessory discharge. As a premium battery disconnect switch, it preserves maximum charge to extend the lifespan of both your 12V battery and vehicle—ideal for maintaining reliability in cars.
  • [Universal 12V Compatibility with 240A Rating & Terminal Sizing] This remote battery disconnect switch works with most 12V vehicles: cars, boats, RVs, ATV, UTV, trailers, trucks, motorcycles, and systems with battery current ≤240A or engine displacement <4.0L. Features dual-size negative terminals (9-13mm & 15-17mm)—not for vehicles with small terminal posts. Its compact design (3.3"x2.4"x1.4") and simple negative-connection method ensure stable, hassle-free integration.
  • [Intelligent Voltage-Activated Protection Technology] Our 12V smart battery switch auto-adjusts to protect your electrical system: - Below 11.8V (±0.2V threshold):Remote control disables, and power cuts after 120 seconds to prevent deep discharge - Above 13.2V: Remote locks during driving to avoid accidental shutdown—uses only the manual switch for safety. Perfect for preventing dead batteries in all 12V setups, with 500A instant current handling for surge protection.
  • [Pre-Installation Guide: Measure for Fit & Clearance] Critical before ordering: Inspect your vehicle’s battery compartment to confirm dimensional compatibility (3.3"x2.4"x1.4"). Check if side or flat mounting is needed and ensure the hood closes fully. This simple step avoids installation issues and guarantees a secure fit in cars, trucks, RVs, and marine applications.
  • [Premium Performance Specs & Easy Installation] - Technical Details: 12V rated voltage, 240A continuous current, 3mA ultra-low standby power, and a wide operating temp range (-22°F to 194°F). - Installation Tips: Connect via negative terminal only (turn off all power first). Test ignition after installation to ensure proper functionality. Trusted by DIYers and mechanics for reliable, low-power draw battery management.

Product works as suggested, I can kill the switch from around 50 yards way, I haven't tested any further.I urge you to read the instructions or your gonna fry your device and other electrical components faster than a speeding bullet!That Big blue box, yes that one that's huge with the 2 doohickeys on it!Now I know most of you know this, but that big blue breaker goes on the NEGATIVE side, one red wire crosses over and hooks to the positive side and attachment on the bolt.

THis battery kill switch is really hand if you own a land rover with persistently leaky wires (it's a lucas joke)... Seriously though, if you want to completely disconnect your battery from your main load circuits... this is your tool to do it.The problem I have with this is that it's a little flimsy..well okay, a LOT flimsy. But damn if it doesn't work well. The remote is handy; no more popping the hood all the time to unhook the battery.While the quality is ...questionable, I cannot deny the functionality of the cut-off. You have drop below 12.9 volts for it to work, so if you try to turn it off while your engine is running (assuming the charging system is working properly) this unit will not activate. If you have a high float voltage the you may need tap the breaks, hit the lights, or flick the HVAC on.. this will typically cause enough draw to drop your car's voltage below that 12.9v number.3 stars: Recommended with the "flimsy caveat".

I recently installed a Kill Switch/Battery Disconnect Switch on my SUV that was experiencing a phantom drain. It has appeared to fix the problem of the battery going dead. This device allows me to disconnect the battery quickly with a remote control and a failsafe cutoff at 11.8 volts, even if you forget to press the remote to disconnect the battery.The installation process was straightforward by attaching just the negative side between the car and battery and another wire to the positive terminal. It is very easy. It’s compatible with any 12 volt battery vehicle, and the compact design fits neatly under the hood without interfering with other components. A side effect is that when the disconnect is engaged the car is much harder to steal.This Kill Switch is a highly practical and reliable solution for anyone looking to enhance vehicle security and maintain battery health. Highly recommended!
