Mounting Shimano batteries upside-down

[Jil]

Hi !
I'm designing an ebike, and I plan to install the battery below the top tube (external model, 504 or 630 Wh : E8016 or E8010), facing downward.
Is this installation authorized by Shimano, and technically suitable ?
Thanks

Well I don't see why not as a battery works in any orientation. Ideally it needs to be as low as possible to bring the centre of gravity down.

I'm concerned by the clipping system.
But on my Bosch eMTB, the inner battery faces downard with no issue.
