Review: Good value in a reliable part - 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.
Review: Good Enough - Not super duty but easy crimp. Works for my solar installation needs.
