Ok, do I really have to mention that my battery is half the size? Sorry I'll be more specific next time
This 30 minutes to 80% (~2C charge rate) is pretty much the state-of-the-art for nearly any battery without working very hard. Assuming the charger can supply enough power and all of the the internal wiring can handle it, it is independent of the size of the battery.30 minutes to 80%
Assuming you have a 100 kWhr battery, either the CT or the Lightning should easily do this with a 200 kW or faster charger.
I'm not totally clear on what your point is. I'm just trying to clear up misconceptions in your statements.
