The leaf pack is fused with a 200 (or is it 225?) amp mid-pack fuse, so
I'd say they are rated at around 200 amps + safety factor...
I used some (totally overkill) 1" wide by 1/4" thick copper bar stock
when making my interconnects.
I was sizing for a 500 amp max draw using 3 parallel leaf modules.
Bussbar construction starts at around the 3 minute mark at the video here:

I'm trying to figure out what the constant and 30-second Amp ratings are for
some Leaf Busbars.
The ones I have measure 0.78" wide by 0.08" thick.
That calculates out to 40.25 mm2 (yeah, changing units)
1 awg wire is 42 mm2.
BUT the busbar isn't insulated, and has a much larger surface area, so won't
heat up as much.
1 awg wire is rated at 0.13 ohms/1000 ft.
It's about 1.25" between modules in a Leaf pack.
That comes out to 0.00001354 ohms.
at 200A, there should be a voltage drop of 0.0027V, or 0.542 watts.
What I'm trying to figure out is if I need to stack several of them for the
5p17s pack we are probably going to do for a friends truck.
