3P battery connection with provided 2-holes busbars: use a washer to fill in the gap or make custom busbars?

[trougnouf]

I am in the process of modeling my 3P8S battery out of 304 Ah cells from Amy, and I just realized that using 3 parallel cells with the provided two holes busbars means that the busbar is not making contact with one of the terminals.

Would it be appropriate to use 2 mm washers to fill in the gap, or I should make custom 3-holes busbars? Is there anything in particular I should watch out for (s.a. material)?

Z bend in a vice?

Bending could work if can do it. You could use copper washers. Don't use Steel or Stainless washers.

That's a great idea that didn't cross my mind Not sure I would be able to do it well though. Will see once I get them.

Thanks! I will order some copper washers. It looks like M6 (I believe that's what the terminals are?) with 2 mm width are hard to find so they'll probably come from China too and be a while to get here.

Do not ever use any washer between contact surfaces.

Actually it works out perfectly if I use two of the busbars as terminals


(I do need to get more busbars though, I got 24 of each in my order.)
Still curious about the right ways to go if this issue pops up.
