SELTERM 10pcs - 1/0 Awg - 5/16" Stud - Battery Lugs - Ring Terminal Connectors | with 12pcs 3:1 Black & Red Heat Shrink Tubing with Adhesive | Heavy Duty Battery Cable Ends - Bare Copper Wire Lugs Kit

I recently used SELTERM copper lugs on my truck and,overall they’ve been a solid performer. The copper (or tinned-copper, depending on the variant) gives excellent conductivity and handles heavy current loads without noticeable voltage drop or heating.When crimped right the connection feels very secure — tight fit, no loose strands, and good strength that stays stable even if the cables move or the system vibrates,which adds flexibility. No fuss with the cable ends, and the lugs looked durable and built-to-last. I like it.

Reviewing: SELTERM 10pcs - 6 Awg 1/4" Stud (Wide) - Battery Lugs - Ring Terminal Connectors with 12pcs 3:1 Black & Red Heat Shrink Tubing with Adhesive, Heavy Duty Battery Cable Ends I have purchased this brand before in different sizes, and they worked particularly well in my hydraulic cable crimper. I dislike wasting time repairing faulty electrical connections when I just need a piece of equipment to work, and a properly crimped and sealed connection is my best insurance against such disappointment. Pros: The terminals are nice, thick, malleable copper. They are made in India, which can be hit or miss for metallurgy. These can be bent and bent back a few times without hardening and snapping off. The heat shrink tubing is the thick kind, with the adhesive sealant inside. If you choose to use these in soldered applications, the metal tins relatively easily. The flared ends make inserting stranded wires a breeze without ‘stray hairs’ poking out the sides. These are about as good a value as anyone’s likely to see in smaller quantities. Cons: you can see a little variation from one part to another, but the holes are all of consistent diameter and they all crimp down the same in the end.

Bought these to wire up some compressors and audio for my truck. Nice, high quality, solid copper ring terminals. If your buying these, plan on buying a crimp tool if you don't have one. I have a hammer one I use to lock the wire in. Also, they do not come with heat shrink ( not they claim they do, so its not a negative ), so be sure and order some so you can make a nice pretty connection.

The lugs worked great! Very happy with the quality, good value. Will purchase again!

These are good quality fittings.

The SELTERM 4/0 AWG XL Battery Lugs are exactly what I needed for a reliable, professional-grade power setup. These ring terminals are solidly built with thick, high-conductivity copper and a clean tin plating that resists corrosion. I used them in a 48V battery bank for my off-grid system, and the 5/16" stud size matched perfectly with my bus bars. Crimping was smooth and secure—no cracking or distortion—and the connection feels rock-solid under load. These lugs handle high amperage without heating up, and the pack of 10 offers great value for serious electrical work. A must-have for any high-current DC project.
