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

Smaller than 0 gauge

Product was just what I wanted,a sturdy strong copper terminal and fast shipping.

Great quality product. Works as you’d expect.

Good quality and price

Inside packaging was open and only recieved 8 parts...not 10 as sold.

I 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.

Prompt delivery. Good value for the mon.

Goo0d part and very rigid

As Amazons photo is so crystal clear, so; I didnt like 3/8 hole along with not enough of copper around the hole. I had decided to get 5/16 for tightly fit my batterys bolt, that I had really love. I had though, to bore the 5/16 at 1mm. larger for fit, that I didnt have to.

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.
