Very interesting, but I see an issue with the longevity of the cells, where this approach would require full charging and close to full drainage to make it viable. Those would decrease their lifespan considerably, right?
Also, as cells die, replacing them seems like a lot of work (or perhaps not).
Using them for niche purposes would work I guess, like you mentioned. Longer wings with lighter cargo for short trips seems reasonable.
Thanks for the explanation
