iGreely10pcs 2 Guage 5/16" Wire Lugs Ring Terminal Connectors Ends 2 AWG Heavy Duty Tinned Copper for Battery Cable Lug Wire Electrical Eyelets with 10pcs 3:1 Dual Wall Adhesive Heat Shrink

Summary: Previously bought the SELTERM brand, 2 AWG, 5/16" lugs, 25 pack, so will be doing a direct comparison to these. I use these for a solar/PV battery bank, jumper cables.Observations: $10 for 10-pack, $1.00/each.Recommendations: If the option is available, buy in bulk for a quantity discount.Pros: Decent fit & finish; IGREELY makes a lot of electrical components (specialty); lots of different sizes available; includes red/black heat shrink.Cons: Not a proven name brand like SELTERM.Conclusion: At $10 ($1.00/each), rating this 4-stars (less proven). I can highly recommend either the SELTERM, which is a proven brand (and the #1 Amazon Choice).Related Products:SELTERM 25pcs 2 AWG 5/16" Stud Marine Grade Tinned Copper Battery Cable Lugs ~ $23 ($0.94/count)4.7 out of 5 stars    5,205 ratings | 44 answered questionsAmazon's Choice in Ring Terminals by SELTERMhttps://www.amazon.com/gp/product/B073FGB1B2

I used this product to terminate some 2 gauge copper cable for a solar system. The product works well and is high quality. My favorite thing about the product is that it is a tinned copper terminal so it will last almost forever.

I made up wires to put 4 batteries in series for my solar system. I bought a small hand crimper with a bunch of unmarked vice things that I used for crimping. These were the first things I've used that crimper on and it did a fine job. The little flare at the end of the connector makes it easy to insert the wires and to position the crimper.The shrink tubing is a nice touch.
