  • Top quality !!!
Size: 4 AWG Color: 25 Ft. Red + 25 Ft. Black
Much better than the ones from EWCS and the Excelene from South Wire, which are somehow stiffer, "dusty" and stinky.

  • Expensive but ... Biden!
Size: 000 (3/0) AWG Color: 15 Ft. Red + 15 Ft. Black
I don't know if they are heat resistant, not very maneuverable as they are 3/0 but seem to be well made. Very heavy... but that is a good thing. Solid stranded copper, heavy insulation.

  • Flexible and easy to work with
Size: 0000 (4/0) AWG Color: 10 ft. Red + 10 ft. Black
I purchased this wire for installing LiFePo batteries, solar, and a 6000 watt inverter/charger in my RV. This wire is durable and easy to work with. When making 6" jumper cables between batteries it was easy to bend and make connections without straining.

  • Exactly as advertised
Size: 6 AWG Color: 15 ft. Red + 15 ft. Black
Very good quality, good value, excellent flexibility, very little "coiled" memory. I purchased15 feet of the black and 15 feet of the red 6 AWG wire. When it arrived it was in a much smaller box than I was expecting. The two 15 foot lengths of wire were coiled very tightly together. I thought that it would retain this "spring' like shape after uncoiling it, but I was very pleased that after uncoiling, it straightened out. Some other wire that I have purchased with a vinyl or "plastic" insulation retain a "spring" like condition even though the wire strand count was large and the wire diameter small. Also I see NO evidence of any Aluminum used in the construction of this wire (ie CCA). I would like to comment on an item that interested me. In the description it indicates that the wire is annealed copper. What I found about annealing is that it creates a softer more ductile wire, which contributes to the wire's flexibility. However I also found out that annealed copper is about 2.5% more resistive than hard drawn copper. The magnitude of the copper resistivity is 1.68 as compared to annealed copper resistivity of 1.72 . This is most probably of little concern to most, but maybe there are some that will find this of interest. Righteous buy ... show more

  • Good product!

Used to relocate my batteries on my SxS from under the seat to the bed. Holding up great and not dropping voltage extending the wires an extra 7 feet away from source.
