  • Good quality
Size: 4/0 Awg - 1/2" (M12) Ring Number of Items: 8
I've bought these lugs a few times for a few projects. I find them to be excellent and sturdy with a good amount of copper. They don't succumb to the crimper too easily/wimpily. The shrink wrap shrinks down nicely with a heat gun.

  • 2/0 heavy copper lugs for batteries
Size: 2 Awg - 5/16" (M8) Ring Number of Items: 10
Very good product. I was not sure what I would get off Amazon and usually like to look and feel for quality before purchase. I had to purchase a couple sets of these and have drop shipped so I could go to work upon my arrival. I am very satisfied with these as they are solid copper, crimp very tight and well. Are heavy duty and the heat shrink works great. ... show more

Purchased the 0 gauge version to run solar batteries in parallel. The connectors work fine and hold well to the battery connectors. The shrink wrap included is a nice touch. A great product that does what its supposed to.
