For instance, if you set to charge to 80%, stopping at 5AM, will both chargers stop charging at 5AM? ( I would assume so, but just checking. )
Bzz, sorry, wrong. What the LEAF really does when you ask to stop at 5AM is typically stop anywhere from 10 minutes to 2 hours before your target time. If you need more charge it could end up starting 2 hours before super-off peak TOU begins and ending 2 hours before it ends, a most unpleasant scenario. The miscalculation is proportional to the amount of charge needed so if you're only charging for 2 hours the offset isn't important but when you live in Virginia with a 4-hour window (I know you Californians get a 5-hour window but we only get 4) a 4:45 charge as is typical with my 70-mi per day 100% commute the offset could be as much as 90 minutes and so the timer will typically start (if set to the ToU SOP end of 5am) at 22:45 the previous night and finish at 03:30, by far not ideal. But if I just fake it and tell it finish by 06:30 (which would get it to finish about the right time under that scenario) and for some reason have a small charge required the night before I may end up charging 100% on-peak because peak begins at 6am (we're really tight on the ToU here in Virginia).
Point being with the 3.3kW charger I'm constantly doing very weird algebraic permutations of my charge timer to get it to finish before at least Off-Peak ended at 06:00. With that 6.7kW it's nothing but start at 01:00 (start of SOP) and by 05:00 and I'd always get a full charge by 05:00! Sigh.

See my comment above.
