Cons

  • May not fit well in tight battery compartments
  • 3mA standby power consumption
  • Manual switch access might be difficult in some installations

We tested this Csyibeielec kill switch on an older truck with occasional battery drain issues. Installation was straightforward, taking us about 20 minutes to connect it to the battery terminals.

The compact size (3″ x 2.7″ x 2.4″) worked well, though we had to be creative with placement in our tight engine bay.

The remote feature quickly became our favorite part. After parking for the weekend, we simply clicked the remote to disconnect the battery power completely. No more worrying about returning to a dead battery!

The smart voltage protection is clever too – it automatically cuts power when voltage drops below 11.8V, saving your battery from complete discharge.

We appreciate the safety feature that prevents disconnection while driving. When voltage exceeds 13.2V (typical while the engine runs), the remote deactivation is disabled. This stopped us from accidentally cutting power while on the road.

The manual override switch provides peace of mind if the remote ever fails.

The kill switch handled temperature changes well during our testing. Even in cool morning conditions around 40°F, it functioned perfectly. With a 240A rating, it’s robust enough for most personal vehicles. The standby draw of 3mA is minimal but not zero – something to consider for very long-term storage.

Perfect for weekend warriors who frequently leave vehicles sitting for days or weeks at a time.

After using it for several weeks, we found it’s especially valuable for seasonal vehicles or those not driven daily. The peace of mind alone makes it worth the investment. For anyone with older vehicles prone to parasitic draw or electrical gremlins, this simple solution could save you from repeated jump starts and battery replacements.

Daily operation couldn’t be simpler. We just press a button on the remote to disconnect the battery when parking for extended periods. No more crawling under the hood!

We did notice you need to wait about 20 seconds after turning off the engine before the remote will work, which is slightly annoying but serves as a safety feature to prevent accidental disconnection while driving.

The build quality feels solid for the price point. The switch housing is sturdy plastic with weather-resistant seals, and it’s handled several rainy days without issues.

We’ve found it works perfectly for our truck and would work well on boats, RVs, and ATVs too. Just make sure to measure your battery compartment first, as the unit needs adequate clearance to fit properly.
