> stack several of them for the 5p17s pack
While it looks like you have done the calculations on voltage drop
and heat production, and the values are acceptable, I'd question the
wisdom of trying to build a 5p pack using the Leaf busbars, mostly
because layering up multiple short busbars to parallel the modules
will result in a large number of junctions between the busbars,
resulting in even more resistance and a lot of clutter on the terminals.
When I built up the 2p5s pack for my Electrak this spring, I went to
fleabay and bought some appropriately-sized copper stock, ran it
through the drill press and made custom-fit busbars that could span
four modules (paralleling two each and making the needed series
connection between the paralleled modules).
The only purpose for the stock Leaf busbars was to tie the middle
terminals of the paralleled modules together. In my case, that was a
good application, but if you are tying five center terminals
together, I'd even make custom bars for that too, although they won't
need to be very big, as in a perfect world, there isn't going to be
very much current flowing in that part of the circuit.
