Charging curve: power the aircraft accepts against state of charge. This aircraft can use its full curve on a 500 A cabinet, because 400V means the same power at less current.

Worth knowingNormal turnaround is a two-hour charge; the figure here assumes the fast-charge ground unit. A 21-minute flight on a 38 kWh pack leaves very little margin.

Pack voltage

Modelled from 300 V at 0% state of charge to 400 V at 100%, so roughly 330–390 V across this session. On a 500 A cabinet that is 165–195 kW of headroom, against a curve that peaks at 50 kW. The pack's own taper arrives first, which is the comfortable way round.
