If so, it's designed to hold 2 cells, right?

Each assembly of 2 cells in 2p comes with some surrounding plastic that clips together with a heatsink in between. There is also some special foam provided to provide even pressure on the adjacent cells. There are some good pictures

I weighed the 24 cells shown on a bathroom scale (not the most accurate I know) and it came to ~26.4lbs. That doesn't include the end plates, 4 bolts to hold the stack together or bus bars. I am using 1.2lbs/cell as a good estimate of per cell weight with all this extra stuff.
For bus bars I am going to use 1/8 x 4" 6061-T61 aluminum. From ampacity charts, it should be able to carry ~585A with 30C temp rise, and 780A with 50C temp rise. As I should be seeing no more than 600A peak for only short durations, I think I should be fine. I'm seeing much higher temp rise than that with my current copper bus bars from Thundersky (and 1000A peak).
