I just started with the new two-hole-style terminals. I tried to get them in the single hole as I had many leftover parts I could have used. But they do not make them like that anymore. I preferred the single as it allowed me to set the height easily for the busbars and other components. Interestingly, my old busbars fit the hole spacing, but they are off-center. I plan only to drill one hole, hoping the parallel bars will help even the pressure across the series connectors. After I get one built, I should be able to offer a better option on it. Screws are already an issue as it's not easy to locally source aluminum m6 x 20mm screws.kromc5,
Nice work! A question. You have some pics showing complete systems using the single stud style terminals, and the start of a system using the twin hole style. I can get my cells in either style -- do you have any thoughts on the differences? I note that you only used 1 hole of the twin style.
Also, in the complete system, where you have 4 cells in parallel then series connected to the next 4, you not only connected both sets in parallel, but you series connected each pair of cells (rather than 1 or 2 jumpers to the next set of cells). I'm thinking that solution (but with one or 2 jumpers) as it has more flexibility, or a single plate (say 3" wide by 8" long) with all the holes drilled in it. More rigid (a down side) but much cleaner/simpler.
