500A Remote Battery Disconnect Switch 12V DC Car Kill Switch Anti Theft Kit Prevent Battery Drain Remote Kill Switch for Car Auto Rv Truck (2 Keys)

Works perfect on 1999 Corvette with a battery drain. Tried another brand name but it was a failure. This one did the trick. Had to add a couple of pieces for the side post style battery. Had it on for about 3 weeks now with no problems. Insulation took me about 45 minutes or less.

Im using this for a make shift garage stereo setup and to keep my batteries from draining and isolate during the charging. Its kept up great and makes it really convenient to shut everything off on my way out of the shop

I needed this because I am going to use it for a cut off switch to the second battery that powers my audio. And I needed one capable of handling 350amps. I am doing this because the audio battery is AGM and the starting battery is a regular flooded lead acid battery. If the two batteries stay connected while the car is off, the audio battery will try to constantly feed power to the starting battery because AGM batteries have a higher resting voltage. And the audio equipment does draw a minute bit of power even when the equipment is off. I didn't want to use an isolator because I want both batteries working in parallel when the car is running. So this was a great option for me. I have tested it and it works fine. It is easy to install, just use the negative terminal. It is nice and beefy too. I will wait for a cooler day to install it. Great value.

Terrible product. It’s supposed to save your battery but the instructions literally say it will not work after 10 days…it will kill your battery instead. Plus it arrived with missing bolts loose in the package. Don’t buy this if you’re looking to save your battery or need to leave your car parked longer than 10 days.
