Video Transcript for Deka 2/0 Gauge Battery Cable Harness Review and Installation

Hi there RV and Trailer owners. Today, we're gonna be taking a look at and showing you how to install Deka's, zero to two gauge battery cables for parallel circuits. These cables come available in either a black sheeting or a red sheeting. Depending if you're using it for a negative parallel connection or for your positive parallel connection. They are designed for parallel circuits. So, they are designed to hook negative to negative for the black one and positive positive for the red one to add the capacity of your batteries together.

So, these are really mainly for 12 volt batteries. If you have six volt batteries, you would connect those in a series circuit and potentially a series parallel depending on how many of those batteries you have. We do have series cables available here at etrailer. And it really does depends on your battery. These cables could potentially be utilized in that situation if you needed to.

But you will require a top post like this. The other issue you run into is the length of batteries. With series, you can see there are posts that are next to each other which makes these the perfect length. With a series connection, these will likely not reach from negative to positive in a lot of situations. It really depends on how you've got your batteries oriented.

Another thing I wanna point out is that if you're going with a parallel connection If you are using the top posts style Your negative posts are slightly smaller than your positive posts. So, those top post ones, you do need to pay attention to those. I like that these have just a connection, so we can connect to a screw top. That makes it a lot easier. You don't have to worry about whether or not these cables are gonna fit like a top post style.

I do like that it does come provided with top post attachments though. So that way, if you do have that sound in your trailer you can utilize it. And you can see here that the negative one which is down below is slightly smaller than the positive one that came with our positive cable. So that way, they're gonna be the correct size because if you try to put a positive clamp on one of the negative ones Oftentimes, you tighten it down really far and it's still a little bit loose. And you can end up damaging the cable by over tightening it. And it's the exact opposite. If you try to put a negative on one of the larger top posts, you end up spreading it out. And then, when you go to tighten it down, it often damages and deforms the metal to where it could potentially break. So, having the right cable is gonna ensure that your trailer is gonna have a proper connection. That's gonna last a long time. It's gonna be solid and delivers all the power that you have potentially coming out of your batteries. We'll begin our installation by first locating our batteries. Oftentimes, in your trailers they're gonna be located in your front compartment. Ours we're located right here in the front compartment. We did have to take the lid off of them because it had a lid that covered them up. Many trailers have that. You just take the screws out and the lid pops off. You can see our own lid here. It had about four screws that held it on. Sometimes, you may have battery cables that are connected to the posts here. You'll make, you wanna make sure you to disconnect those or you can just set the lid off to the side. If the cables are long enough to be out of your way. Our customer didn't have these hooked up. So, now that we got access to the batteries, we can go ahead and remove the old battery cables. These cables are designed to hook batteries in parallel. So, these batteries are already hooked into parallel. We can see these are smaller battery cables. We're gonna be putting out some heavier duty ones. So, we'll use a 9/16 to 14 millimeter. The size is gonna vary depending on your batteries. To remove our post, we're gonna remove the ground first. And we're removing the ground that's actually connected to the trailer first. This is the wire that's going off to the trailer. So, we're just gonna pull that guy off, pull this one off. Then, we can go ahead and we're gonna remove the positive mount to our trailer. so, pull that off. Set that guy aside. We'll disconnect our positive cable from our trailer. So, now we're fully disconnected from the trailer but we need to get these posts out, or these cables out of the way. So, we'll go ahead and remove those now as well. So, now we can go ahead and install our new cables. We'll start with the positive cable. We're gonna slide it over and I'm putting the cable towards the inside kinda towards the middle of the batteries. And you can see that there are a perfect length for two side-by-side batteries like this. They're about seven inches in length. Now, you do get new hardware included with your cables. However, they may or may not fit on your battery. It just depends on the size. The ones that come included with it are gonna be too large. So, we're gonna use the ones that we had previously removed to attach the cables. We're just gonna put the nut on there, get it started. And then, we'll get the nut on the other side started. We'll then, do the same thing with our negative cable. And again, we're gonna use the hardware that we had removed, since the hardware that comes with the cable's we're a little bit too large. And you'll notice that I didn't connect the trailer cables back up to the battery posts like they we're previously. So, we'll go ahead and snug these down. And then, you can see that there's posts here at the top. Now you do have a couple of options, depending on how you're connecting your trailer to your battery. Whether you're using a top post like this. This will actually thread on here and you could attach to it, or. the nuts that come included with the kit could also be used. It just really depends on which one's best for your particular setup. Sometimes, the top post might be just a little bit too long for your battery compartment. You can see here, it does stick up quite a bit higher than the previous cable that we had on there. So, it just depends on which one's best but it's nice that it has this option. It gives you a much cleaner look cause we're connecting our batteries together. And then, we've got posts there that we can easily attach our trailer to. So, we're just gonna go ahead and take our cables then from our trailer, we're gonna slide them on. We're gonna go ahead and use one of the nuts instead of the top posts just because of the top of our battery box. I do believe it is tall enough but we don't want to have a clearance issue. Then, our negative table, bring over to this post. And as soon as we plug it up you can see things are starting to come alive on our trailer. Go ahead and tighten them down. They are gonna be a 9/16, for the nuts that come included with the cables. And that's basically it. We've now got our connections made and you can see it's a much cleaner connection than we had before. And the large gauge of our wire here is going to ensure that we're gonna be able to get the most amperage out of our batteries as necessary under the various loads that we may have. Using a thinner cable sometimes can limit the output depending on whatever the cable is potentially rated for. So, having this larger one here is going to ensure that we are gonna maximize the potential that our batteries have. And that completes our look at Deka's zero to two gauge battery cables for parallel circuits..
