The E-Trek has a relatively small interior volume as compared to a Class C, so I imagine that it's air conditioner is a bit smaller than the typical 13,500 BTU Class C air conditioner - hence less battery amp hours to run it.
Probably the air conditioner run times they talk about are with their largest AGM battery bank option - eight AGM batteries for a total of 1600 amp hours. Their optional lithium ion battery package is two batteries for a total of "only" 800 amp hours. They state that the reasons to select their LI battery option would be to reduce overall RV weight and to get the shortest coach battery bank recharging time.
As a side note, the Earthroamer RV also powers it's air conditioner from it's AGM coach battery bank - as it doesn't have any 120V AC generation capability on board (just two large alternators driven by it's diesel main engine).
Look around on this E-Trek page to eventually get to what they claim.
