I dont see why there would be a major difference in SR battery automation vs LR. I would assume its the same machines, just less cells in the pack. I assume that they thought of this when they designed the pack to make sure that the same hardware could build both packs. I am not going to claim to know what it will take, but it seems to me that you could make 2/3s the modules that go into the pack and then there is some kind of spacer that takes up the excess room. I am sure its a bit more complicated then that, but it would seem to me to be one of the easiest problems to solve when compared to the problems from automating the pack production.
