Monster cable
Size: 4/0AWG, Color: 3ft Black + 3ft Red
Well I now know what 4/0 or 0000 cable is. Huge but very easy to handle or bend to shape.

Direct Connection

Received the package in good condition. This wire is a decent quality. I made a set of jumper cables with it and they work excellent.

bought twice to make custom UPS setup battery leads, not disappointed
Color: Black, Size: 25-Feet
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)
