Where the 8.0Ah sits in the range

The first genuinely high-capacity M18 pack, and the point where the OEM part switches to pouch cells. That matters for equivalence: a cylindrical-cell build at this capacity is a different pack in size, weight and thermal behaviour, so confirm what your customer is comparing against before quoting. Specified for continuous-load tools and full-shift work where swapping packs costs more than carrying weight.

At 144Wh this pack sits in the 100–160Wh band: air freight is possible but needs carrier approval and Class 9 handling. Sea freight is the usual route for volume orders.
