DaFuRui Remote Battery Terminals，8Pack 8mm 5/16" Stud Premium Remote Battery Power Junction Post Connector Terminal Kit (4Pcs Red & 4Pcs Black)

well made and work great .

I bought these for the lifepo4 batteries in my camper to replace the battery bolts the batteries came with. These are really great and install easily. They also have removable spacers and nuts so you can adjust the length of the input posts to whatever length you need. These posts make changing wiring so much easier. No more removing the bolts, adding or subtracting cables then re poking the bolt thru the cable connectors and trying to get the bolt back in to the battery socket. Love these things

I used this junction post for the battery charging side of my solar recharged battery bank in my Jobsite toolbox.

I use these to connect lpo4 batteries to a battery box for a DIY application. Great conductivity and easy quick release if needed.

wired my pontoon for power and these work great

Just perfect for my project

Easy to break plastic, poor conductivity, impossible to tighten down so they don't spin and loosen during use. Low current use only. These would be dangerous for any high current application, automotive, solar, RV, etc. There no way to secure them and keep them tight while in use and the conductivity between threads on a bold and the nuts is terrible, they will heat up much too fast under load. NOT SAFE, DO NOT USE.

I would NOT recommend, for one simple reason: You have no way to prevent the spinning on the inside when you tighten the outside, so you are guaranteed to have the inside loosen as you do/undo the outside. Then you find yourself with a bad connection inside without even knowing it, and this can even be dangerous because it could easily cause sparks. You might say just add two lock-washers inside that sandwich your wire connector, but you'll probably and up with a bad connection there (very little surface would be in contact with your connector). So nope, sorry.
