High quality, cuts well, ICE cold at 300A continuous draw
Excellent 4/0 gauge welding wire. High quality. Flexes well. The blue wire in the picture is a different Amazon brand. I used this product to wire an off-grid expedition truck with 32,000Wh of lithium batteries at 54V. It was used as the parallel jumpers, for the positive side of the battery pack to the positive bus bar and the negative side to the negative bus bar. Then, I ran from each bus bar to a 10,000W inverter. I used exactly 5ft of red and black. It was easy to strip back the insulation with a razor blade and crimp 4/0 tinned copper lugs. I cut the wire with a metal cutoff wheel on an angle grinder. The insulation barely turned to dust, and it cut cleanly relative to other brands of 4/0 gauge wire I've used (like the blue one in the pic, which became blue dust). I'm used to having particulate colored dust from the insulation, but this insulation is like pure rubber or something. It cut so clean. I'm pulling 300A continuous through these over a 5ft span, and they're ICE cold. Will gladly buy this again when needed. They also look great. Proper red and black, just like any heat-shrink you'd find. You might be able to find cheaper locally, but online, or especially on Amazon, this is a great deal for 5ft of each color.

High quality and made in the USA
This wire is 100% copper (not copper clad) true to size (I ordered 4/0), very flexible and made in the USA. I needed this cable for an inverter setup on an OTR truck and it worked perfectly.

High quality.
Way too expensive, in my honest opinion, but this is the sexiest cable I've ever seen. Super beffy, yet still flexible. Will cost you a fortune if not a short run.

Good & flexible
Finally fitted this to my Caravan ( Travel Trailer Merican) inverter and house batteries. Handles the DC current easily with my 2000 - 4000 watt inverter. A metre doesn't go far and I used the lot.

Heavy, thick, quality wire.
Don’t think I need wire quite this thick but better over doing it than under when dealing with lithium batteries and possibility of fire. This with a 400 amp quality fuse connected to a 200ah lithium phosphate battery will do nicely👍🏻
