Where the 5.0Ah sits in the range
The volume SKU of the LXT range. It is the capacity most 18V kits are built around, so it doubles as the price anchor for the rest of the series and as the natural first order for a new customer. It also carries the shortest lead times here, because the cells it needs are the most widely stocked.
At 90Wh 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.
