These are outstanding. I’m currently using them in a 36v golf cart that I installed a single 36v battery in. The old busbars I had were underrated for what it needed, and I have multiple electrical components that need power. These work perfectly. I mounted them inside of a project panel box to keep them water sealed. They bolt down tight, and feel very strong. Very pleased thus far.

This box is not light. It's made of heavy gauge metal and closes tightly with water shield for the wires. Definitely made for under hood, RV or marine use. I just wish they sent more of the weather proof wire inlets. Only the red box contained them.

Very nice, sealed, professional looking terminal blocks. Using them to connect batteries on a solar setup and will definitely be getting more.

I haven't put a ton of current through it yet, so I can't speak to that, but it appears well made and I have no issues so far.
