Thanks. I have a 25 ah Lithium Battery “starter set” I am going to be putting together prior to the 280 cells arriving.stainless steel for flange nuts and set screws

Now I'm wondering what the thread count is for the M6 studs on my Eve 280s.I acquired a couple different lengths of aluminum M6 bolts that I plan to use. I could very well end up with a whole pile of stripped bolts. But I will at least be able to say that I tried.
That is why I am looking at the Nord-Lock lock nuts between the BMS lead and the nut on top.A serrated flange nut on top of the bus bar is workable. A serrated flange nut on top of a balance lead, I'm not so sure about. What's to keep the ring terminal of the balance lead from turning against the bus bar?
I tried the management route. Didn't like it. Rumor has it that the HR department had to add a checkbox item to the exit interview form that said, "Jim's a Bastard!"
I recently learned about Nord-Locks and all of the info I have found on them shows them to be superior. They can also be reused whereas nylon lock nuts really deteriorate when being taken off and put back on again.I use the serrated nut and then add a nylon lock nut on top of that. I like the larger area of the serrated nut and wanted the lock nut for vibration. That was with threaded holes and I ordered studs long enough.
With the welded studs on my latest cell purchase, I'll have to look at the stud length but I think they will work. I do fab my own busbars out of thicker copper and nickel plate them.
The bolt in the welded studs is stainless in most cases. I haven't heard of aluminum nuts, but I don't think they would have much strength. The conductivity is between the battery and the buss bar. The bolt or stud you use isn't the electrical path.What type of nuts are you using?
The stud on the Eve 280s are M6, but not sure of the bolt material. I'm guessing aluminum, but an aluminum nut could be hard to find.
M6 is almost always a 1mm pitch count, 1.25 on M8.Now I'm wondering what the thread count is for the M6 studs on my Eve 280s.

i didn't say otherwise... I mentioned the sequence on one side of the BMS lead, not the busbar on the other side...The ring terminal of the balance lead should be on the bus bar.

Loctite actually works better. But you run the risk of contamination of the electrical connection using either.If you are using S/S studs, do yourself a favor and don't use a S/S nut. It can gall up / cold weld, and you will never be able to get it undone without ruining the battery. If you absolutely must use all S/S hardware, put a bit of antisieze on the stud.
I am assuming it takes a certain amount of pressure before galling occurs. I haven't used high pressures, but I have put SS nuts on SS bolts, on and off, several times in my testing. Perhaps at 4 Newtons there isn't enough pressure to cause the oxide erosion to being the galling.If you are using S/S studs, do yourself a favor and don't use a S/S nut.

No, I did not rewire. I added a 16 gauge wire for a shunt to measure voltage.Next you are talking 16GA? Did you rewire your BMS connector to 16ga?
Thanks. I searched far and wide for those, hours probably, and did not find those.I had good luck with these from Crimp Supply.
26-24 Ga. Heat-Shrink Ring Terminals, 1/4" Stud

and this crimper via Amazon: Channellock 909 9.5-Inch Wire Crimping Tool
Yes, they are expensive. Also liked the heat shrink they used. Seemed to really seal up well even around the crimp. Just FYI, they also shipped really fast.Thanks. I searched far and wide for those, hours probably, and did not find those.
I can't believe how expensive ring terminals are getting.
