Excellent Quality, Super Strong and Perect Design
The Best Battery Terminals money can buy. There lugs are extremely well built with good design and top quality material which crimps very well. The lip is thick and holds very well when connected. Size is slightly bigger for the 6 AWG Grounding wire, perhaps because I am using solid copper wire, however, after hydraulic crimping it came out as a champ. Most other terminals sold on Amazon are thin and cheaply made, but this one is very different and designed for tough performance. I already ordered another set to keep them as spare. Recommended to everyone.

Nice heavy terminals
Terminals crimped nicely. They were a little snug to get 95mm/2 cable into but otherwise worked well. Good Quality

Does the job
These are what is needed for a 4/0 awg cable . These are huge so I’ll have to make them work . Very strong and heavy which is needed for an inverter install

High, Reliable Quality
I have used this brand for every thing from 6ga wire to 4/0 battery cable on solar installations and Lithium battery conversions on Class A motorhomes. These are well-suited for the purpose and cheaper in bulk packages.

Vary solid lugs. Only issue is the shipping, Ordered May 15 arrived June 3. Being a prime member had no effect on shipping. If you are ok with that order as many as you like.
