[5pcs] 4 Awg - 3/8 Stud, Copper Wire Lug, Ring Terminal, Battery Cable End, Cable Lug, Wire Connector by KeeRoarin

Decent enough lugs to get the job done. Crimps easy enough to wires and carries power through them without making a hot spot when used appropriately. Using these on the terminals of 24V lifepo4 batteries in parallel to upgrade some UPSs life and runtimes, they are doing decently so far. Should last the life of the device.

I have a decent sized solar setup and I am constantly upgrading or changing things around. I go through a fair amount of terminals, mainly in setting up the connections between the various battery banks and the inverter. These lugs are copper, fit perfectly, crimp and solder easily. Exactly what I wanted. 5 stars for matching description exactly. Note: I have been an Amazon customer for almost 20 years. I write all of my reviews to reflect my personal observations and opinions on a product. It matters not if I have purchased the item myself or if it was provided to me for review. My goal is to provide other potential customers as much real-world knowledge as possible to make an informed decision. In most cases I will return to my review in 6 months or less to see if I should alter my original observations. In no case will the cost of a product influence my opinions at all. In addition, I will try to include multiple images and or videos on each product, if practical.

These are good quality lugs that fit my wire and crimped perfectly. How My Star Rating System Works & What They Mean: 1 STAR - Pretty much junk and I would return and ask for a refund if I could. 2 STAR - It works, but barely meets the minimum requirements it should in order to keep it and not return it, but I would not order again. 3 STAR - It does what it was designed to do, but theres nothing really special about it. Its acceptable but not great. 4 STAR - I am very comfortable recommending it to a friend because it is is well made, durable, and delivers on its advertised features, and I would buy it again. 5 STAR - I really love it. The item exceeds my expectations of quality, durability and functionality. Not only would I purchase it again, but I would also actively encourage friends and family to to do the same. All of my reviews are my own personal opinion and are completely honest no matter if I receive an item for free or I pay for it. I am an avid Amazon shopper, as well as an Amazon Vine Voice and I personally rely on reading reviews to make all of my buying decisions, so I understand the importance of honest reviews from my peers.

I do like that these guys have very specific ring sizes as well as (obviously) being for specific sized cables. Im a stickler for the 2-hole, 2-crimp method wherever possible, but its usually not possible outside of grounding and bonding, so these are pretty nice.

Great - Solid copper accurate sizing The foot of the terminal where you mount the lug is about 2mm thick and will mount without bending too much on its own. Flared receptacle end, crimps easily

I used these to rewire my travel trailer. They worked very well, perfect size, and held up perfectly. I compared these to lug connectors to ones I bought at Napa and these are the same (if not better) quality.

I used some of these to build new golf cart power leads. They were easy to crimp, and hold secure. I actually crimped them down to 4ga, as I bought 2ga by mistake, but since they are copper, they crimped fine. I will probably tin the next few for longevity, and to protect against dissimilar metals on certain areas they are attached.

I got the 8 AWG - 1/4 lugs. They have a nice thickness. I cut into one with a Dremel and it seems to be solid copper. An 8 AWG wire fits fine and a 1/4 bolt fits the ring with only a bit to spare. Exactly what I needed!

I wanted to try these to create a grounding loop for my pool. I wanted to attach them to the metal frame of the pool. Theyre actually a bit bigger than what I needed, but I plan on doubling the 8 awg wire before putting it in. Pros: High quality Durable Easy to crimp Strong enough to support high voltage (for battery applications) Affordable Cons: None that I can think of. Overall, I am happy with these. They are exactly as expected, and Id recommend.

I would call these terminals medium duty. If they get too thin they may not hold the crimp and the type of crimp used also makes a difference. If used in a severe environment these terminals could be soldered if needed. I’m happy with these terminals. I’m using these to install a DC to DC battery charger.
