Top Post Battery Disconnect Switch 12V-48V Battery Disconnect Switch 12 Volt Waterproof Cut Off Switch Positive On/Off for Marine Car RV Boat ATV UTV Vehicles

Well made product. Installed easily, works fine.

Worked great on my 2014 Club Cart Precedent (48v) and easy to install with the included directions. This switch makes it so I no longer have issues with battery drain between uses so I don’t have to remember to keep it plugged into a trickle charger. The voltmeter is a nice benefit too so I don’t have to guess how much juice is left in the batteries before I take the cart out. The wire grommets also help keep the connections clean and look professional. I just turn the knob and go with no affect to performance at all.

Seems to be high quality. Works on my motor home to isolate cranking battery from charger when plugged into 120 volt. Cranking battery shouldn't be charged like that as it shortens the lifespan of the battery. When I'm plugged in I turn it off. When I get ready to roll I turn it on. I drive it weekly so the alternator takes care of it like it does on any car or truck. Motor homes are famous for voltage loss any way and this stops that.

Works reasonably well but I have had it turn off randomly on me.

Good value for the money. Quick and easy to install. Great for older vehicles or classics that you have and keep the battery from dying. Feels to be good quality

Built extremely well. It’s solid and the switch is easily accessible. I’ll definitely buy more. The cost was definitely worth the price.

I originally purchased two of the 1-2-Both switches. When I checked out of the box the switches worked as they should. However, I never checked operation once I had connected battery cables onto each of the post connections, tightened the nuts on the post and mounted the switch. You want to do this when working with large currents as it can causes issues later if they aren't tight. Fast forward about 6 months after my purchase. I had a bank of batteries that went bad. I went to check the bank and got a nice little jolt. So, I started disconnecting cables directly from the batteries. I then dismounted the switch and decided to check it. Sure enough it didn't turn off when in the OFF position. To make matters worse, It didn't shut off connection 2 when in Position 1 and didn't shut off connection 1 when in Position 2. So just to make sure I wasn't imagining things, I pulled the cable connections from the switch and checked it. It worked fine. Position 1, 2, 1+2 and Off all operated as expected. As soon as I reconnected the cables it stopped working and started shorting contacts. Unfortunately, I had already ordered two replacement units thinking the originals had just gone bad and the originals were out of warranty (I had them for about 6 months). So I now had four of these switches. So I decided to check if this was just something with one of the switches or if they all had the same issue. Nope, they all had the same issue. I had a switch in place that not only caused issues with my battery banks but is a huge safety issue. I have gone to separate banks now and I'm waiting on a switch that is a single connection only. I hope this is an isolated case. However, you should check your switches to ensure that AFTER you tighten the cables to the connection posts with the included nuts. Ensure that not only do they connect for position 1 (to the 1 location), position 2 (for the 2 location), for both and that it does NOT connect on position 1 when you are on position 2 and not on position 2 when you are on position 1. It should also not connect when the position is set to the off position. If it does, this is an accident waiting to happen.

easy to use, cheap should work for me

Good option for a kill switch, especially for EV cars. Quality of the product is good and easy to use.

Easy to connect & works quite well. We got a few now of these little gems

Connections are lose to body and doesn't work

Quality of this product is fabulous, I started using this since last one month there is no issue, by using this instrument the we can increase the battery performance as well. I am suggesting others to use this fantastic product.

As I had a rather tricky situation to makes things work on my tractor, I had picked this particular product for its flexibility. This model is for a positive post hookup and seems to be fairly well built. Installation completed a few days ago and everything working.
