### ⭐⭐⭐⭐⭐ A great bus bar

### ⭐⭐⭐⭐⭐ Does the job.

This works well. Cleans up the install on my 36 volt lithium battery conversion on my EZGO golf cart.

### ⭐⭐⭐⭐⭐ perfect for my situation
*by R***S on May 8, 2025*

Got these to move all the wired devices onto separate contacts for the solar setup in my van. I had at least five devices all going to the single end terminals on my leisure batteries and it was quite a stack! This is much nicer, safer, and makes it easier to remove/repair just a single item if I ever need to. I won't have to remove the entire stack and unplug my panels just to address one issue. One of the best buys I made recently for my vanlife project.
