Used it to wire up my boat for trolling motor. Heat shrinked everything and went super smooth. Great deal!

The Thick Red and Black Spaghetti of Power
Size: 20FT Black & 20FT Red
If electricity had highways, this would be an interstate. The cable feels substantial, the copper conductors are flexible enough to work with, and the included lugs and heat shrink tubing make installation easier. Great for batteries, inverters, solar systems, RV electrical upgrades, marine projects, and welding setups. Voltage drop stays low thanks to the heavy gauge construction, and the insulation feels durable enough for demanding environments. Overall, a solid wiring kit that inspires confidence when moving serious current.

Great cable kit.
Size: 20FT Black & 20FT Red, Size: 20FT Black & 20FT Red
Great heavy duty cable. Good thick feeling insulation that looks the real deal. Wire is soft enough to route easily without too much resistance. Appreciate it coming with the lugs and heat shrink instead of you having to source extras. Seems to be truly copper as listed. Great deal for the length if so. Worked for what I needed on my UTV.

Cheap price for the cable and terminal ends with heat shrink.
Size: 20FT Black & 20FT Red
Good 6 gauge wire, jacket seems sturdy and like it won't crack easily over time like some wire. Comes with all the connectors shown too so you don't need to find end ring connections to terminate the ends. Just need a punch or crimp tool for the terminals but if you already have that then just cut your wire length and add the ends for battery cable.
