Joinfworld Battery Disconnect Switch 12V-48V Waterproof Marine Battery Cut Off Switch Master for Car Boat RV ATV UTV Vehicles

Used this for a battery disconnect on my class A motorhome. It has a bolt top connections on the battery in lieu of side or post connections. The battery bolts are smaller than the 3/8” bolts provided but the existing bolts were small enough to go through the 3/8” hole on the disconnect. I then used a smaller bolt and nut that would go through the cable terminal to fasten the cable to the other connection on the disconnect. I just installed it but so far so good.

Works as described. The only problem I had was that the bolt was a bit short for my needs but as it is a standard size replacement was simple. I do recommend it

Have some sort of a parasitic drain in my car and can’t afford to leave it at the mechanic for a weekend so this is a great alternative to ensure the battery stops dying. Product comes with everything to accommodate multiple mounting options, though it is larger than I expected, I was still able to make it fit. It’s been over a month and it’s holding up very strong. My battery hasn’t died since installing it so it is doing what it’s supposed to do. Annoying I have to open the hood every time I need to go somewhere, but it’s a great bandaid until the economy decides to stop self destructing.

would be perfect if it were shorter or angled 90 degrees so as to minimize the risk of it getting too close to metal car body

Excellent & convenient to use! Plan to take it on an international trip!

Easy to install works grest

Worked OK but difficult to work with heavy gauge wire/terminals due to their compact size. If you are space constrained these will work. If you have space get a larger unit. Much easier to work on.These aren't super heavy duty. As I stated, they will work but they definitely anr NOT the tougher battery selector I am used to seeing in boats.

It does what I want it to do. easy to install.
