DENGFU E22 BATTERY THREAD

[BonBond]

The E22 FRAME THREAD is amazing, nice people and a font of knowledge....but it's huge and unwieldy now.

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.

Bike is finished now, will give it a paint job at some point, but quite happy with the flat black and the glossy decals I made for now. Thanks everybody who helped me here - seriously appreciated! :love: (spot the 'deliberate' mistake).
