Questions & Answers

Does this work in the same way as a dual battery isolator, which charges two batteries for different purposes at the same time?

Let me state that the BEP that I purchased and used on my boat with two batteries performed admirably and was of superior construction. The Horsmile was poorly constructed, and when I attempted to tighten the nuts that held the Red battery leads, it broke. With very little tork, it was simply snapped apart. The answer to this question is that it depends on how things are wired. In my case, battery 2 had an extra lead to a fuse that kept the juice flowing to the bildge pump regardless of the battery's condition, and it worked as long as the battery lasted. as if the boat had been submerged for an extended period of time and had developed a leak When it comes to charging, what do you think you should do? What is the electricity source and where is it located, as well as how is it wired? Please feel free to enquire about anything else. My switch is now as good as new, and I was able to finish the job with the BEP device and plenty of tork to tighten the positive Red battery leads without breaking them.

Is it possible to remove "both" from the list?

Yes, you should not set the knob to "both." It can't be turned off in any other way. There is no way to stop the knob from reaching this position mechanically.

How do you wire it so that when you're on 1 or 2, you get 12 volts but when you're on both, you get 24 volts?

Your 12 volt batteries must be connected in series to achieve 24 volts, which has no bearing on this switch. You can connect your batteries in series and then connect one wire to this switch.

These are something I've used before and they're great
5/5

In my boat and camper, I have four different models of this switch. All of them have performed admirably and are simple to set up. It's easier to check which settings go to which connector a, b, or both btw if you have a meter.

Solar energy is a renewable energy source
5/5

It's perfect for my solar panels on the camper and my batteries. With a pointer on the knob, it's easy to see which battery you've selected.

For two or one battery, this is a great tool
5/5

For my boat, this is an excellent product. I've also used this on a pontoon I used to own, and it's a safety feature in my opinion. The trolling motor is powered by two batteries. If the gas engine fails, I'll be able to get to shore with the trolling motor for at least another 4 hours on the reserve battery.

The switch for the battery bank is active
5/5

There are no surprises here; everything functions as it should. The use of 2/0 cable connectors is not a problem. The cost was comparable to that of similar/clone switches. This was a low-cost method of adding a second parallel pair of batteries. Each bank is equipped with two parallel batteries.

As predicted
4/5

It's a nice product, but there's not a lot of room for joining 4 or 6 gauge terminal wires. The terminals are in close proximity to one another. To get it to work properly, I had to file down the battery terminal ends.

On the boat at the moment
5/5

When switching from one battery to another on my boat, this works great. Why spend $50 when you can get this for less?.

It does exactly what I need it to do
5/5

It was simple to put in place. It really works. Because I have two batteries in my RV, I can use one or the other by simply flipping a switch. For easy storage, it also kills both.

The item is water resistant
5/5

These switches are extremely well made and simple to assemble and install. They used to be very expensive, but they are now very affordable.
