"Obviously this would be impossible if airframe designers incorporate battery cells in structural members, as some suggest to offset the weight penalty."

Why not do both?

Swap one part and charge just the internal batteries. But internal batteries does not sound so clever with limited lifetime anyway.

Charging is limited by two factors:

- the power you can get from the charger to the batteries - the power the cells can accept

You can reasonably easily fix the first point with custom infrastructure, so the second point will be the limiting factor, and that one means that it always takes e.g. 20 minutes to charge your batteries, regardless how many you're charging (because with a bigger battery, you're simply charging more cells in parallel, at the same speed per cell).

I've always wondered about this, do electric cars charge each cell in parallel? or are there some series connections?
