I'd like to take several of these (or similar) usb device charging batteries (http://www.ianker.com/product/A1271011 [Broken]) and connect them into an array to create a minimum of 36V and channel that to power a speed controller for an electric vehicle. Is this possible? Would I be able to prototype something like this with an Arduino or similar? Any advice/direction would be really appreciated. Question 2: if this is possible, do the amp hours added together per battery or does that stay a constant? For example, a battery has 2 amp hours - if I have 5 is it a total of 10 amp hours or is it still 2 amp hours? Thanks!
