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

The cables are a good quality and have nice ends. They are sturdy and should hold up well.

Used to contact with 2000 inverter. After a short while, the black cable burns/heats up quickly. You see fumes/smoke coming at the the cable/inverter connection when you put a load like a 700W microwave for over a minute. Power will likely cut off at that time. Happened even for running a small fridge. I had to replace it with a 3ft 2/0 cable from Harbor freight (up to 5000 W). This has been working great. Can now run same devices as needed, and the black cable doesnt show any sign of warmth.

Like others have mentioned, the lugs are not well crimped. Almost caused a fire. Other than that, the quality of the wire and lugs are great -- but whoever is doing the crimping over there needs to be shown how to do it correctly. Such a small error that can end in catastrophe.

Good solid connections

Ordered length is combined length of both cables

These were for my husband to use in his semi truck. He hasnt complained to me and says they have thus far worked great. So I guess they do because if they did not, I would never hear the end of it from him...lol.

Perfect for connecting a second battery on my rv in parallel

Looks robust! Beautiful crimp(octagonish; no indents) I intentionally pulled the lug off (it was really on there good), but not sure it would pass the crimp pull test.
