10pcs 2 Awg - 5/16" (M8) Sanuke Wire Lugs Ring Terminal Connectors Ends Heavy Duty for Battery Cable Lug Wire Electrical Eyelets with 3:1 Dual Wall Adhesive Heat Shrink

So, these are battery lugs. Not quite sure what to say about them. They all accept roughly the size of wire that they advertised and they bolt down to things to form a good electrical connection. The included heat shrink seems decent, durable, and does heat shrink things very well. Like shrinking when exposed to heat.

Beautifully machined product, almost felt bad using it! Very thick, and would definitely pass nearly any reasonable amount of current you're likely to be able to generate.

Liked this product for a few reasons, most important they were very consistent. Using these to make cables exactly the same fort connecting lifepo4 batteries together and to buss bars keeping the resistance equal makes for more stable charging and discharging and this is very important for the life of these type batteries. The shrink tube was perfect size although it has sealing substance inside which it a little difficult to use, not as important for these type of batteries as it is for lead acid batteries. All in all great product.

Worked out good for my needs. Thanks

Perfect. As described. High quality.
