The pic doesn't say anything about who he is but if I have to guess he's got some sort of relationship with a computer shop or battery recycling facility. That way he'd have access to all the batteries that are being returned and could pick the ones he wanted.The graphic in #2,259 shows individual cells all the same size. But what % of laptops on the market today use that same standard?
It would have been prohibitively more difficult to accomplish this same UPS construction using each of the many different standards of Li ion cells in use today.
