Rectangle battery in Frame Triangle?

[Oscdav]

Anyone mounted an Em3v 52V (14s5p) Rectangle Ebike Battery Pack into a bike frame triangle to power a Bafang 750W motor? Help/Tips wanted on feasibility! Thanks.

This is how I put 2000wh of lipo on my bike.

Squares fitting in triangle... er.. uhm.. Slung on the sides.

One big rectangle on each side. IDK if you can do this though.

I install a 14s, 4p (52V, 8ah) on a Blackburn large water bottle frame cushioned by a styrofoam liner. Picture shows the installation without battery.
