Prismatic Cells orientation

[burgerking]

Is it OK to orient prismatic cells on their sides, and stacked on top of each other like this below?

Is there any adverse effect putting them on their sides as against standing upright?

It depends on the manufacturer and the cell construction. Some indicate they can be on their short side. Some indicate long side and others indicate terminals up only.

I do worry seeing a big stack of cells, the load on the bottom units is pretty big, not much fear of them swelling though.

Terminals up is always a good default.

According to EVE documentations, it can be placed under 300kgf clamp.
Stacking 8pcs will exert 7 pcs x 5kg = 35kg of force on top of the bottom piece.

I agree... its just that, stacking them up takes much less space and a cleaner install.

I don't see how this relates to your question. This is about clamping force for improved cycle life. It says nothing about orientation.

According to the context of my 1st paragraph on my previous post: I was replying to crossy's comment "the load on the bottom units is pretty big" and answered that the load is only 35kg which is far below the "300kg clamping force for improved cycle life".

Looking at the photo in the OP I would be much more concerned with the apparent proximity of the cell terminals to the metal containment.

I'd be sliding some 3mm acrylic into that gap "just in case".

I asked my importer, to ask the seller (Basen) to ask EVE.

Upright, obviously
Short side, OK
Long side, no word.
