> 3 dayI needed multiple ring terminals to connect several 12 volt batteries together for a solar battery bank. These were priced well and performed perfectly. I would definitely buy again.

10-06-2025I used these terminals to rewire a Harbor Freight 12000lb Badland winch. The power cables had completely corroded from within. These terminals are 0.400 ID x 0.500 OD and fit 1/0 InstallGear wire perfectly. They crimped well with the IWISS Cable Lug Crimping tool.

> 3 dayThe WNI 1/0ga x 5/16 lugs are great...as long as youre NOT using Sky High Car Audio 1/0 wire. It wont fit without cutting strands. If youre using GP Car Audio, Knukonceptz or most any of the other brands of 1/0 car audio wire you should be good. The fit is snug on the wire. No issues using the hydraulic crimper.
