I bought these to install a lithium battery bank and solar system in my RV and they worked out great! With the funneled opening it is super easy to get that big and bulky 4/0 cable into the lug and fits quite snugly. It was easy to crimp with a hydraulic crimper and made clean and professional connections.I ran out and had to purchase some local to finish my install and couldn't find anything like this when I was shopping. I ended up with another manufacturers product that didn't have the enlarged opening and I fought with it to make sure all the cable strands were in. I did not have that issue with the Selterm connections and now have spares in case I have to replace a cable in the field.
Thank you for your feedback

Reviewed in Canada on March 14, 2024
I use these over the ones that come with the typical "Amplifier Installation Kits"

Quality is just over the top, Sturdy with a good Hydraulic Crimper, overall just 10x better than the supplied in kits.

Also use them when installing a threaded post AGM battery used for Car Audio Applications & the vehicle originally had a solid top post battery & needs Ring Terminals now for the connection.

Highly recommend!
