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.

Very easy to install and use

Works as it should

Like it helps save my life on battery

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.

Be careful I couldn't get it to fit they take up a lot of room. It wouldn't work for my motorhome or my tracker so it is useless to me

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