With today's tech you're spot on. As batteries advance though, we expect ranges closer to 500 miles by the end of the decade, which would indeed enable SF<>LA!
How are you managing battery degradation, especially given that you're planning for high charge rates with quick turnaround? Do you have an idea of how many pack replacements you'll need over the lifetime of the rest of the aircraft?
Amprius is planning to offer a silicon nanowire anode sometime in the next decade it seems, which probably won't double the capacity, but it would be a significant improvement.
