Questions & Answers

The bolt diameter is 10mm, so I ordered two of these. All of the cables and the lithium battery appear to be 5/16 (8mm) in diameter. Is it possible to swap them out?

If you want to use it, you'll need to increase the size of your cables and fittings to 10 mm.

What are the threaded connection posts' dimensions (diameter)?

I'm not at home. Threaded battery posts, on the other hand, should be the same.

Is it possible to connect to two 12 volt rv batteries or should I purchase two units?

To switch between two 12 volt batteries, you'll need to purchase a two-way switch. This switch is a one-way switch only - Activate or deactivate the device.

Is it possible to use a four-battery bank with this?

It all depends on how the batteries are wired together. It's just an on-the-job training program. turn off the battery switch Keep in mind that it's only rated for 275 amps on a continuous basis. It will fry if the amperage draw is higher than that.

Despite being mass-produced in another country, the construction appears to be solid
4/5

I just got this in the mail, and it appears to be surprisingly sturdy for what it is. br>It's obvious that it's a mass-produced Asian product (and the universal packaging, which still has relabeling instructions, helps to demonstrate that), but it appears to be quite sturdy. br>To clarify a few points about which I had doubts when I purchased it; It includes the switch assembly as well as four side panels that slide in and out to allow the cables to reach the terminals as needed. Then there's the base plate, which snaps into place. The entire assembly (black part) is made of molded ABS plastic that appears to be quite durable. The side panels are very secure when they are slid into place. Overall, if you drill a hole in the needed detachable panel just big enough for your battery cable to enter the assembly, then cover it with a little liquid electrical tape, it should be completely waterproof.

In my Casita, it works
5/5

I sent a return request thinking the device was defective, but I discovered it was working as expected because I was still getting power from my trailer connection plug. Once I realized that, I realized the device was working as it should be. Amazon was wonderful in sending a replacement right away, but I think I'll pay to keep both and have a backup. Now that I know this, I've been using it for a few weeks and it's working as it should.

Melted at Lower Amps than Rated - Under 190 amps, the switch melted, posing a fire hazard
3/5

It falls short of the 275 rating that it has maintained for a long time. If you're going to use your battery to run a load, use a different switch.

I'm hoping it sticks around
3/5

This is a six-month-old replacement for the same switch. The switch continued to work, but the detente (click indicator)br>became so soft that it only turned like a knob with slight resistance; I had to check the position label.

Three vehicles have had their batteries disconnected
5/5

Our vehicles are rarely left unattended for long periods of time. As a result, the auto starter and other electric equipment are included. If it is not disconnected, ent will drain the battery. That won't happen because of the disconnect. This seller offers a high-quality product that is delivered quickly, even during peak season. 19 times. I'd bite from them again.

Excellent craftsmanship
5/5

It is well-made. For mounting, the bolts are of sufficient length. Weatherproofing is something I can't speak to. We'll see what happens now that I've installed under the frame of my travel trailer.

Bolts are a waste of time
3/5

If you're mounting to a boat compartment wall, you won't be able to use the included bolts. Sheet metal and self-tapping screws tapping) should be added to the mix/.

It really works
4/5

The battery kill switch is very nice. It does the job I need it to. Solid, to say the least. I'm not sure if the weatherproof claim is true, but I'm using it in a camping trailer.
