That means an actual 240 charger running the full 27.5 amps is needed to do the 6600 watts.

anyway even at 1440 watts a 16,000 watt battery should fully charge in 11.1 hours but I'm sure it ramps down a couple times as it approaches 100%

I bet the 2.5 hrs at 6.6 is a bit optimistic as well, probably more like 3 to hit 100%.

Also isn't 100% charging bad? I can't seem it set other limits. Maybe what they call 100% isn't actually 100%.
Your assumptions are correct.

Note that preheating a plug-in (or EV) usually draws more than the 120v outlet can keep up with, so it will use a little bit of the battery in the process. Generally you need to step up to L2 if you want to avoid any battery drain during preheating.
