4/0 Gauge 4/0 AWG 10 Feet Black + 10 Feet Red Welding Battery Pure Copper Flexible Cable Wire - Car, Inverter, RV, Solar

Thick and ready to party.

The wire worked great and was flexible enough for my project.I had some every tight and short pieces I had to cut and bend at 90⁰ angles.

I had WindyNation WNI 4/0 cables which required attaching 4/0 sized lugs to the ends in order to bolt the cables to various devices such as connecting 2 batteries in series. I quickly discovered that the smaller wirelets that made up the cable would expand and fray outward once the outer insulation was removed. The lugs provided NO CLEARANCE to make it easier to insert the cable into the lugs before crimping the lugs onto the copper wire. Without fail, strands of the smaller wirelets wouldn't fit into the lug, so these had to be cut off. If I also had to cut the cable, they would fray and expand even more, so then I had to remove up to 20% of the outer wire strands to get the cable to fit into the lugs. See first photo.I don't know if the cable was too big, or if the SELTERM lugs were just too small (no clearance). In any case when the cable is cut, the lugs won't fit when the wire strands expand as the insulation is removed. The insulation is tough. The wire strands are tough. When both are put together, the cable is one tough cookie.Even with 20% of the smaller outer wire strands removed from the cable, once crimped, the lugs held on firmly and could not be removed. After applying heat shrink tubing, the connection looked fine. See second photo.4/0 gauge cable was probably overkill for connecting 2 batteries in series, so it's my fault for buying too stiff of a cable. This cable should last forever.

100% copper cable, very flexible and quality sheath. Would highly recommend.

using this for the battery connections in my van conversion. it’s way more flexible than i expected, more so than the 1/0 i got at lowe’s… this stuff has a bunch of small strands of copper, whereas the other stuff had just a few thick strands.easy to cut with some decent wire cutters and im crimping lugs with a hammer crimper

Was 2" short of 10', maybe because of metric to standard measurement? Was otherwise as described and very flexible for heavy 4/0 AWG.

Very good wire for solar battery systems.Flexible for easy installation.Reduces voltage drop to about as low as possible between batteries and solar charger or inverter.Recommend use with at least 3/8-inch copper lugs.Insulation is excellent with nice red color to distinguish with black in dark areas.

Because the wire is so flexible made it very easy to install. Very nice.
