I am looking at options for orientation of cells to get the new cells in the old FLA space... and wondering if I should constrain myself to vertical only, or also consider stacking with terminals on the side if need be.
from what I saw of the internals it seems like having the big flat side down would pose no problems since the 'sheets' would lie flat and stay compressed. I don't think I would line them up on the narrow edge because it seems the sheets might sag, wrinkle, and short or be unhappy.
Anyone have any experience pro/con mounting cell 'stacks' with terminal on the side?
