Just realized I didn't answer these questions.... Well, actually I kind of did in other posts. The bus bars are the ones that came with my 8 x 230Ah Eve cells last summer. I ended up making my own for that build, using copper bar stock cut to the right length, drilling the holes and then nickel plating all the bus bars. For this smaller build I decided to just use those old bus bars, as the 160Ah cells are the same size except shorter than the 230Ah cells.Are those DIY bus bars? What size screw did you use for the balance leads?
The holes that I drilled and tapped for the balance leads are M4. I bought a big jar of 100 or more shrink-wrap ring terminals for M4 for the previous 3 builds, so that decided it. I think I saw that Andy of @Off-Grid-Garage used M3, which would be fine too.
