### ⭐⭐⭐⭐⭐ 







  
  
    Exactly what I needed for our fifth wheel travel trailer
  

*by E***. on Reviewed in the United States 🇺🇸 on May 4, 2023*

In our 5er RV we have two group 31 deep cycle batteries with 5/16” studs connected in parallel to the 12V system for extra capacity. They do have the normal top posts as well, but the connections are ring terminals for a 5/16ths stud. It’s impossible to find a proper disconnect switch like this that just goes on the stud, but this was the next best thing because it has a 5/16 inch stud on the expansion side. I can simply screw down the wire with the ring terminal to it without having to redo it for 3/8”!Where it’s stored for months at a time, I like to keep it on an extension cord to keep the batteries healthy, but power is unreliable since someone keeps unplugging it. So to make it a non-issue I just wanted an easy way to disconnect the batteries altogether to eliminate even minimal drain. This is just what the doctor ordered.It was super quick and easy to install, and it’s certainly quite stiff and solid to operate. If the hinge rivets ever one day have a problem, which I doubt, it will be quick and easy to nip them off and replace them with a short machine screw and nut.Grab a couple of 1/2” or 13mm wrenches, and that’s all you need to cinch it down on the top post. Wing but let’s you secure the ring terminals from the RV in place.

    It is Simple and it Works
  

*by R***B on Reviewed in the United States 🇺🇸 on August 11, 2022*

Use this on vehicles that do not get much drive time to isolate the battery while it is on the tender.
