So there are 12 cells in the battery pack? (12 x SE US18650FT)
With two serially-connected packs of 6 cells connected together in parallel, doesn't that mean its 2.2Ah?
The UK version DE9180 is listed at 2.0Ah

and the smaller UK version DE9181 is listed at 1.1Ah

Why by accurate with the 1.1 and not with the 2.0 (2.2)?
Confusing
