comparing Batteries, $|Volume|kW.hr/$|kW.hr/Volume|etc

[deetoau]

I started comparing battery prices and suppliers on alibaba, preliminary calculations in linked spreadsheet.

I'm sure this has been studied to death by others and there are factors I'm not including in my analysis yet.

The A123 form factor batteries suprised me with their cost, tho I'm also wondering what parts are needed to assemble them into useful packs.
