bought this item(25ft 2awg) twice, the first time I did was to create some quick connect cables between my batteries and my distribution block to my 4kw invertor(24v 165a peak calculated load) I may have oversized due to knowing that the bigger you go the less you stress components and loose power to voltage drop these cables are a nice high-grade rubber jacket and the 30awg strands are ideal for maximum flexibility while remaining fairly easy to terminate this cable also includes a backer paper wrap that allows for easy stripping(of the rubber) without too much strand loss damage(from cutting too close to the core) overall, would buy again, like I did, if I need larger runs(say for feeding an RV solar AC distribution panel) I would buy this brand again, in the 100ft range or so THHN is not ideal for flex connections(strands are way too stiff) but a couple runs of welding cable like this inside something like "smurf tube" would be a perfect high-power temporary connection system, or just a way to isolate a large battery stack used for a solar setup in fact I may do that someday, set up a pallet of LiFePO4 batteries with a large quick connect, and just recharge the massive array(s) at a secondary location where solar is more ideal(or other renewables)

Custom wires for winch solenoid pack relocation.

Color: Black, Size: 25-Feet

Wire is nice. Flexible. Seems good. However the inner liner is not moisture blocking as I assumed from the pictures, it's paper.. still seems like a good price per foot.

Good, flexible (considering it's 2 GA) wire

Color: Black, Size: 20-Feet

Good, flexible (considering it's 2 GA) wire. Lugs soldered on well (using solder pot + flux). The only reason I didn't rate it 5 stars is because it's expensive. Made in USA was a +
