25 pcs WNI 4 Gauge x 5/16 Pure Copper Battery Welding Cable Lug Connector Ring Terminals

I can connect high-amp power switches, batteries, etc. in my solar power system using these and 1/0 gauge wire bought by big lengths. They will fit all the bolt-and-screw connections (516 and 3/8 ) between bus bars, batteries, and various pieces of equipment. I use the 1/0AWG to start with so that as I increase the storage and output capacity of the system, the wires will not need to be replaced.

A lot of pieces for the price.

Not much to say. Theyre true copper, thick enough to get a quality hammer crimp even on heavy 7-strand wire. Good connection and arent corroding at all even months later. Was capable of drilling one out to take a 3/8 lug without the bit grabbing it and turning it into a pretzel, which also says something.

only 7 out 10 in open packaged

Works well

Best price per terminal ratio I found. The quality of the lugs are nice and are as better quality then the ones from my local auto stores and ac Delco store. Theirs are dirty and not as shiny.

Product is as advertised.

Good 1/0 lugs. Cant go wrong.

Item as described/solid copper. However, if you have Sky High Audio 4/0, these are half the size of the stranded wire. These would fit Sky High 1/0, maybe 0awg, it would be tight.

Just as expected.
