SELTERM 25pcs 4 AWG 5/16" Stud Battery Lugs, Ring Terminals, Heavy Duty Copper Wire Lugs, Battery Cable Ends, 4 Guage Ring Terminal Connectors, UL Bare Copper Eyelets Electrical Battery Cable Lugs

Not made of cheap metal but they're just as easy to install as any other terminal of this size. The metal is thick and has good weight. It does not seem to be made with cheap metal. The quality control is very good too, every one I'm the ag looked perfect. Definitely worth your money.

Seem to be good quality metal, great value for the diy'er, good thickness but able to crimp with only pliers. A plus to me

SELTERM Battery Lugs are heavy duty & have a slight bevel to help insert fine cable wire strands. Good assortment of sizes.

I'm setting up a 3000watt inverter/charger which required 4/0 AWG conductors. These terminal lugs are great quality and easy to work with. They fit my setup perfectly.

The ends could be flared a little bit more to help inserting the cable.

These work well with the connection to the valence batteries.

I have worked on cars for 50 years. These crimp on lugs are the best you can find for the price. I fix battery cables and save the customer hundreds of dollars for not having to pay for a factory replacement harness.

I make my own battery cables for Jeeps and I use these connectors because they are high quality. I have bought these in 2 gauge and 4 gauge as well. All of the connectors I have used from this brand have been good copper and well made. I recommend them.

Im using these as part of a system to add a on off switch to a winch power wire so that its not live all the time. These are nice quality and the exact wire diameter and mounting hole size I needed for my project.
