> it barely discharges over a trip like that, which should help with longevity

Only if you don't charge it fully though, right? As in, charge to just below X% when the amount of charge you expect to need is X/2 percent-points, rather than to 100% and not use it fully. At least that's my understanding and how I've been treating my li-ion devices.

Very precisely: it goes from 40.5 (about 80% soc) to 37.5V (about 60% soc) over a 64 km ride.

So indeed, not charged fully. Just enough to stay in the 80 to 20 window, which still gives me about 100 km of range to play with which is plenty and if I need it I can always charge it up fully and run it down but I don't expect that to ever happen. But those would be expensive cycles life-span wise.
