So, in an attempt to make specific information more accessible, I'm starting a new thread here (or a sub thread?), with links to the historical battery chat within the E22 Frame Thread.

Mayners two part battery is the one that I think of when someone is pondering how much battery an E22 frame in stock form can hold as the limit.

Yep, I was super interested in that approach too, somebody else in the frame thread warned me against soft pack batteries though...
Lack of rigidity provided by the soft pack and/or fires.
