Remote Battery Disconnect Switch 12V 200A Car Wireless Kill Switch Anti-theft Switch Prevents Battery Depletion with Two Wireless Remote Car Kill Switches for Cars, RVs and Trucks

Used this in a 2001 VW T4 due to the stereo draining the battery. This works fine, with zero issues. Easy to install, took minutes, but I had to make up a copper strip due to larger battery terminals with various cables. Be aware that you will lose your tripometer reading and saved radio presets using an item like this.

Good quality and do what they say on the tin ! Little bit tight to get on my battery so make sure you have enough space either side etc !

After an hour fitting it. One of the remotes failed to work. Amazon offered a return/refund. Fair enough but another few hours removing and refitting and hoping the new one works is not an option. They refunded me in the end.

Nobody's fault they didn't fit.. My negative terminal is underneath where the wipers are so couldn't fit it shame really

Had it as car battery kept going flat have a parasitic drain this sorted it out switch off when lock car saty it up when returning to car works a treat up to now

Very good High Amperage relay. Ordered this for our caravan but more specifically for the control of the motor movers, we keep our caravan on a narrow drive and end up struggling to get it in and deactivate the movers as the switch is up against a wall in a outside locker meaning we have to leave it further away from the wall to get in to the box, with this installed i can just press a button and disconnect them, no messing about so spot on. You get everything you need to do the task, with the exception of a pigtail wire as you are expected to use the copper busbars, not an issue if you have the tools to make one yourself. Now fully fitted i can park this as far up to the wall as i like and free up space at the same time. Super easy to fit and comes with instructions but the front of the Relay tells you what pins go to what terminal so very easy to install and get going. my only concern it with it being on the 433mhz is it possibly being activated by other 433mhz controllers as this is a fairly common frequency, even so this is still a 5 star item to me as it has made my caravaning experience a whole lot simpler.

This is perfect for a lot of car diy projects it allows you to easily setup these remote controls for your project. The remotes are 433mhz so not a very secure channel but they are great for simple projects. The distance is great and they are very reliable. The relay is rated for 11 to 15 volts of power so keep that in mind when using this to control your project.
