About this item

  • 【1-Click Protection - Upgraded Heavy Duty 250A】Tap the keychain remote to immediately cut off power, thwarting potential theft and halting parasitic battery drain. Whether parked in a bustling lot or stored remotely, your car, RV, truck, ATV or boat remains safely guarded, particularly useful for long-term parking, anti-theft measures, car wiring changes, accidentally leaving lights on, and dealing with aging wiring.
  • 【Dual Control Mode - Remote & Manual Convenience】Switch effortlessly between the compact remote for everyday ease and the manual ON/OFF button. The battery disconnect switch features 5 bright green LEDs that light up to confirm each action, eliminating uncertainty about your vehicle's protection status.
  • 【Smart Voltage Guardian - 12/24V Wide Voltage Compatibility】The kill switch constantly monitors battery voltage. In smart mode, if the voltage drops below 11.4V, the remote control function is disabled to prevent accidental shutdowns. The switch operates normally within voltage ranges of 11.4-14V or 23-27V, ensuring your battery is always safeguarded. If the battery voltage is below 6.5V, the device will not function. For voltages between 6.5V and 11V, remote control is not available, but manual control is supported.
  • 【Long-Lasting Performance - Ultra-Low Standby Current】With a standby current of just 0.007mA—significantly lower than the original vehicle's 65mA—this kill switch ensures your battery stays charged even during extended periods of inactivity, providing reliable long-term protection. [Please DON'T disassemble the device on your own to avoid damaging the circuit board, which may affect the normal use of the product.]
  • 【Premium Copper & Anti-False Contact Protection - Durable & Reliable】Crafted from high quality copper, this battery cutoff switch boasts enhanced durability and reliability. This upgraded model features enhanced accessories for a more secure installation, advanced design to prevent false contact issues, and ensures a stable, safe connection with superior, lasting performance.

I thought it was a little difficult to install, but I didn't expect it to be quite simple. The remote control is convenient and easy to use.

This remote-controlled battery disconnect switch is exactly what I needed for peace of mind when storing my RV or truck. With just one click, I can cut power to prevent theft or battery drain. It’s easy to install and adds an extra layer of security to my vehicle setup.What I Like:One-click remote shuts off battery instantly—great for security and battery health.Manual switch option is handy when I don’t have the remote.LED lights confirm the power status, so there’s no guesswork.It uses almost no power while in standby—perfect for long-term storage.Built with durable copper and designed to prevent false contact which is nice...Concerns:Remote won’t work if battery drops too low (below 11.4V), but manual control still functions.Not ideal for someone unfamiliar with basic installation—requires a bit of setup.This is a smart and reliable way to protect my vehicle battery and prevent theft. It’s especially helpful for anyone with seasonal vehicles like RVs or ATVs. I feel more confident leaving my vehicle parked for long periods now - seriously.

Disclaimer: My rating system: EVERYTHING starts at a 5, and goes from there. I thoroughly read the descriptions and if I don't like the description, I simply don't order the item. If the product shows up as advertised they get a 5. If there are unadvertised flaws, they are duly noted and stars removed accordingly.... that being said:This item gets 5 stars. It comes securely packaged with everything you need to install it [minus tools]. The instructions are very clear and easy to understand. Once installed it is simple to operate and has a clear readout on the digital display. My only concern that will be answered with time, is since it has a lead wire to the positive terminal to keep the switch engaged is will it drain the battery over a period of months or not....For now the product works great and as advertised, and is highly recommended. It is reasonably priced for the product, and is well made.

Item as described, install was easy. Installed on a pontoon battery. I was able to reinstall the battery box cover over the switch. Switch works fine with cover on too.
