1/0 AWG Gauge Red + Black Pure Copper Battery Inverter Cables Solar, RV, Car, Boat 12 in 3/8 in Lugs

I used these to help relocate my battery to the trunk in my Nissan 240sx. These worked out great and were the perfect size. I had a few minor gripes. I have purchased different wires from WindyNation before. These are not exactly the same at the other ones I have purchased. These are a more stiff and they have a more fixed curve. No matter what I tried the wire would not assume a more straight path. It was not a huge problem for me, but I had to plan ahead. So when I wanted to run the wire from point A to B, I had to make sure it aligned with the natural curve of the wire or it would take considerable strain to bend it. I cut one end off each wire to put on a battery terminal. I thought that would allow the wire fibers to loosen, but it didnt have much effect and the wire remained curved. When I crimped the battery terminal, I had to make sure it was twisted correctly. So I mocked up where I wanted the cable to go, and I used the cables natural curve to go where I wanted. Then I made sure the battery terminal was placed so that when I put the wire on my battery, it was not fighting me and trying to bend another direction. Hard to explain in words, but just imagine that the wire would want to be curved only in one direction. If you wanted to bend it another direction, it would take considerable force and would cause a constant strain. The copper inside looked great. Looked to my inexperienced eyes to be pure copper as advertised. The outer cover was thinner along one edge for the red cable, but not for the black cable. It still looked thick enough, but I wondered if this was why the cables were curved. In the pictures you can see both wires. Actually both black wires are the ones from this purchase. I wrapped the red wire in a foot long length of shrink wrap to make it look black. As you can see the label is gone since its shrink wrapped. The red wire was from another WindyNation purchase, although it does look short enough to be the red wire from this purchase. This red wire was much more flexible and maybe you can tell from the picture that the wire is very happy to be relaxed in an almost straight line. The red wire from this purchase did not really like that position so I used it to curve around the side as you seen in the pic and it worked out great for me in the end. Sorry about the pics, amazon re-flipped them upside down and sideways to their original orientation. I cannot re-flip them to the correct orientation.

Heavy duty and quality copper wire. No aluminum.

Top quality power cables, used them to upgrade the ground connection from the battery to the frame and power to alternator. I will order additional lengths to add grounds where needed. These cables are true 1/0 gauge, well terminated with high-quality shrink wrapped terminal rings. This is considered to be a big 3 upgrade, which should increase the alternators charging efficiency. The theory here is since the alternator is doing less work to provide charge to the system, load on the power plant is lowered. More horses freed up for what theyre supposed to be doing.

The terminal ends were fastened perfectly. Used them as jumpers to create a parallel connection between these two lithium batteries I purchased from Battle Born Batteries in Reno. NV. Perfect

These are very well made cables. I used them for my home inverter/battery backup system. They also shipped fast and arrived quickly.

Great cables

Heavy duty and the right length for my usage. Allowed me to place battery on wheel well to start skid-steer when on board one died. couldnt replace on board one with arms down. Couldnt raise arms without it running.

Very well constructed. Multiple separate purchase from same seller. Good stuff!

Nice, beefy cables with great flexibility and serious lugs.

Caution check that both ends are crimped on properly, the negatives ends fell off with a slight tug. Only held by the heat shrink. Used the positive and when adjusting it after a week of use also came apart. Thankfully I wasnt driving, and I had already gotten a lug crimper for another project. Otherwise they seem to be of good quality and have enough flex to accommodate awkward positions.
