They arent easy to figure out the first time.
The 6 modules come out together, no way to do one at a time.
Disconnect busbars first, put the orange covers back on.
There are 2 bolts on each end of every module, you have to get a long tool to get them.
There are also the obvious 3 mounts on top.
The cooling port on the side, nothing complex there.
Once you do those and all the wiring, there are 6 more bolts underneath the pack. I do those last.
The way i did it when i had no forklift, was flipping the pack upside down and rested the MODULES on something, not the shell. A few 2x4 will work.
That way, when you have the screws out, you are lifting the much lighter shell off instead of the heavy modules out.
Good luck!
