EWCS 1/0 Gauge Premium Extra Flexible Welding Cable 600 Volt - Combo Pack - Black+Red - 10 Feet of Each - Made in The USA

Flexible, durable, easy to work with, and nice slim profile for it's size. Insulation cut easy but is still durable enough to stand the test of time. Best part is, it's real copper and high strand count! I used these for the battery relocation on my daily driven IS300. Worked perfect, I had about 8-10 feet of each color leftover for extra/backup. No electrical issues with the car whatsoever, the wiring turned out OEM quality.

I picked this wire to have on hand. I ended up using it mostly to repair some seriously damaged wires between my F150 starter and the battery. The previous owner had a battery acid leak at some point and I'd been putting bandaid fixes on it for a while. I put some loom over it, taped it up, and used some nice copper lugs to run new lines. The gauge is complete overkill for this to be sure, but this wire was really nice to work with. I was able to route it where I needed it with no hassles. Despite the beefier gauge, it was much easier to deal with than the OEM wire. It's real copper wire, not copper clad aluminum. I'm not certain how well it'll hold up to how I've used it, but I think the use of dielectric grease, generous heat shrink, and the loom should keep this repair going for a long time without issues. I'll definitely be buying more to have on hand, though in a smaller gauge. For those asking if you can use this for the Big 3 (or Big 4) the answer is yes. This is probably a good amount of wire for that upgrade in most installs. Look into what lugs you'll need for where your wiring ends though. I ended a bit big on my lugs and ended up having to add some washers to ensure better connection at the terminals.

I used this cable to make my own battery cables and upgrade my charging system on my project vehicle. I am running a high amp alternator to help out the high amp accessories I am running. I upgraded the charging system and noticed an immediate gain in efficiency from the alternator. With the larger cable and super fine strands, the resistance dropped considerably. I tested the system before and after the upgrade. I decided to use the cable for my amps as well. Easy install and no worries about not having enough juice for the system. The cable is flexible, easy to solder, and easy to add terminals. Just have to wait and see how abrasive resistant it is. Good cable for the money.

Good heavy duty cable. Used it to relocate the battery to the trunk of my car. Lots of wire stands and nice thick insulation. Cable is pretty flexible. Tip on cutting it. If you don't have a cutter capable of cutting cable this thick, don't try to cut through it a little at a time with diagonal cutters. It will fluff the strands out and they're impossible to get to lay back down and it if you're crimping a properly sized terminal lug it won fit on. I do not have a cutter, so what I did was strip about an inch of insulation where I wanted to cut it, wrap it in electrical tape to hold the strands in place, then cut it with a skill saw equipped with a metal cutting blade. Worked like a champ.

I'm using this wire for car audio. It's pretty high quality the only thing that I was concerned about is the layer of cardboard type material Between the sheath and the actual copper strands, I've never seen it before but it seems to be doing pretty good with my stereo system. It's a lot cheaper than buying actual car audio wiring, which is pretty much the same stuff except with a more flexible coating. If you're running a system that draws a lot of current then buy this stuff. I'm sure it's pretty good for welding as well that's just not what I'm using it for so I couldn't say for sure but like I said it's definitely high quality pure copper.

Nice and supple, easy to strip, easy to crimp, everything I want from cable like this. Hands down this is my favorite brand for heavy gauge wire. I use it to connect large lithium batteries to bus bars in my solar power system.

Very flexible for the size. We had some 2/0 wire in our shop from a local source (a smaller size than the 1/0 I ordered) and this wire has much smaller strands in a larger actual diameter than that wire, The smaller the conductor strand per overall diameter the higher the conductivity and lower resistance. I bought this to make a high quality set of jumper cables and am very happy for that use. It may be too flexible to use as primary cable on a vehicle unless you are willing to have many supports or zip-ties.

My go to 1/0 gauge wire, I’ve used this wire on every car audio system I’ve done and never had an issue.
