The lithium pack is nominally 12.8V. I finally recognized it's based on a multiple of 2. 2 to the 7th power = 128. Anyway, after startup it settles in around 12.6-12.7V with engine running. Driving without headlights but with simple radio running, it sags to about 12.5V after about 1 hour and 15 to 20 minutes drive. I can drive home at the end of the day - without headlights - and get home with it around 12.3-12.4V or so.
Turning on the headlights is enough of a draw that voltage drops about .4V, regardless of where it was before switching them on. Not a problem when the pack is freshly charged but for running headlights on the trip back home, I will delay turning them on so I'll have enough charge to complete the trip with lights on. I'm sure the headlights draw more current than the computer + fuel pump + radio combined.
With this past weekend's work on the switches and wiring, I can easily reactivate the front lead acid battery and the alternator without tools. So the car is fully capable of going as far as one would want, just might need a refueling stop after ~500 miles or so
