The cells will be graded on the factory floor and then installed into packs in the same assembly line. Way to much effort in double handling the cells by shipping them in between each step, let alone trying to match cells in a pack on the other side of the country. The difference in transport weight between them is trivial being about 2ton a cbm (35cf), if in a box or pack, so weight is already the limit.I don't think the battery pack is that complicated (all things considering). Wouldn't it be cheaper to ship the cells? IDK if they are transporting battery packs they will be weight limited before space limited on trucks.
Will they transport by rail?
This is why I think this first pack will be different from the Texas packs.
Around 170kWh is all that will comfortably fit in the area between the wheels on the CT in one layer of cells, so as previously I think 420miles is going to be the number in a single layer pack, but all will be Quad motor standard, there might be a performance version, using better cell grades, but otherwise there will be no software limits either. Motors will be the same, like in the M3/MY performance software upgrade option.
Technically, the 2170 pack could be just as structural as the 4680 pack, if not more so because the smaller cell size has more cell wall area and more distributed structure. Externally, there need not be any difference at all to the structural pack, the 4680 cell is only 10mm higher (3/8") than a 2170 cell, so the external housing could be exactly the same for each, and either could flow into the same assembly line as required by production numbers.
