The form factor I'd like to see standardized would be a flat pack like the Nokia phone battery.

Not saying the cylinder doesn't have it's place, but so many of my devices would like a flat pack.

If that happened, it'd have the added benefit of being able to standardized a bms protocol for the packs. Hard to have control pins with a cylinder.

And if you were super clever, you'd make those packs stackable so they could be charged and discharged together.
