Loaferz look closer, you're getting the 8Ah Power Stack battery.
The Power Stack batteries don't use the cylinder battery cells internally, they are flat rectangular cells stacked on each other making it smaller than if the cylinder cells were used. That 8Ah Power Stack battery is still pretty big and heavy.

You re correct about the POWERSTACK internals... BUT, this 8ah battery is a POWERPACK that does use cylindrical cells, the difference is that they use tabless "technology" to offer a higher current output and are sold as [now, apparently] 4ah and 8ah. POWERSTACK is sold as 1.7ah, 3.5ah, and 5ah.
POWERSTACK was first and offered higher current output in a smaller package. The 1.7ah is amazing (high output and tiny), 5ah seems good but not worth the premium (high output but nearly as big as a 6ah ("older" non-tabless style) that would do the same), and I haven't yet been able to try the 3.5ah.
POWERPACK is the new thing on the block, the 8ah was the first and the same size as the regular 6ah & 8ah batteries and is supposed to have much higher output and the 4ah is the same size as the slim 3ah & 4ah batteries (not sure if the 4ah is actually on sale yet).
Maybe deck builders and roofers who want an all-day battery.

Probably, but even that can be inconvenient if you are up on a roof building a house or something that doesn't have power yet.
