These can't be used with the Delta 3 Ultra, correct?

Delta 3 ultra doesn't have an expansion port. The Ultra Plus does.
Either way I believe the ultra plus uses the larger pro expansion batteries.

Essentially the same or a bit worse than the deal for 2x Delta 2 Max batteries on Costco a few weeks ago ($1199 for 2 batteries, 2048 kWh each), different power unit of course
