4/0 AWG Gauge Red + Black Pure Copper Battery Inverter Cables Solar, RV, Car, Boat 2 feet 3/8 in Lugs

So these aren't quite 4/0 AWG when I put them on a micrometer. They measured out to be about 3 square mm short of a full 4/0 AWG but at this price this hardly matters. If you are proper sizing your wire, that minor difference doesn't matter. You should never be running your wire on the ragged edge like that for that little wire to make a difference.The sheathing is good, and it is not as stiff as I had feared. The ends were crimped on well and I had no issues what so ever getting them installed.Overall I leave it at 5 stars giving they are basically perfect minus minor measurement discrepancy. These are so far above 3/0 AWG that it is 4/0 AWG for all intents and purposes.

Very nicely built, crimps appear very solid.

Nice crimps.

Good quality cables / well crimped ends. Changing out my battery bank to all these ready made cables.

Well made, but the heat shrink used is not the type with internal adhesive. It should have this for a marine environment.

Heavy duty. Very happy with these.

No issues. Great quality cable. Crimps look good. Note: the total length of the cable was a little longer than the description. So if you’re looking for exact measurements, keep this in mind. I’d definitely buy again.

Quality cables from a local manufacturer - I highly recommend; this is my 2nd purchase from them. First purchase was 2/0 and now I just bought a 4/0 set. Crimps are solid, cable is pure oxygen free copper, not copper clad aluminum (cca).
