4/0 AWG Gauge Red + Black Pure Copper Battery Inverter Cables Solar, RV, Car, Boat 12 in 3/8 in Lugs

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.

I bought the 4/0 one foot cables. Far more flexible than I thought they would be. Seem to be well constructed. Pleased

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).

Is as advertised nice and heavy 4/0 cable and I tried to twist end as hard as I could and they don't budge.Needed for 2000watt dc inverter 250amp max draw and this should handle it. Rubber coating is good as any other mfg I would say.

Using these on a 3000W inverter and 300Ah 12v bank, pushing 275 amps at times. No issues. This is dense, heavy copper cable. Not as flexible as others claim to be and are, but I don't want flexibility when it means currency carrying capacity is reduced. This is beefy cable.

Appear to be well made, and priced is comparable from other vendors. 4/0 lugs are larger than I could crimp with my tools.

I was using this wire for my audio and found out that 4/0 welding cable is way smaller than 4/0 audio wire

Great quality heavy duty cables.

I've been buying heavy gauge cables for about 15 years using them for high power inverters and solar projects. Cables ranged from ok to terrible, sometimes even even the crimps came loose. Well today my 4/0 7ft Windy Nation cables came and they a WAY superior to anything I've ever seen! The cable ends are solid and tightly sealed with an adhesive shrink wrap, they are very very flexible, and the insulation is a thick and rubbery with the scent of REAL rubber very similar to tires. It may sound silly but they are a delight to even hold lol. I will never ever buy a different brand again! I'm even going to trash all my solar MC4 cables and treat my system to some Windy Nations lol. And to top it all off my cables came two weeks earlier than the estimate Amazon provided.

The media could not be loaded.  They use something like a hole punch to hide what is written on top which then puts a dent in the bottom on the lug which means it won’t fit flat which could cause fires

Arrived early, good quality.

I bought this for a boat inverter and ordered a5 foot length. When I received it the packaging said it was 5 feet long but the product was only 4 feet long so I had to return it.
