Where the 4.0Ah sits in the range
The step-up capacity most retail programmes lead with. Noticeably longer runtime than the compact pack, in the extended housing, at a price that still reads as mid-range on shelf. It is also the least supply-constrained capacity in the series, which makes it a safe SKU to commit volume to early in a programme.
At 72Wh this pack stays under the 100Wh threshold, which keeps air freight and passenger-baggage rules straightforward — the simplest capacity band to ship and to sell into retail channels.
