I can't get the numbers on this one to work. One has to either ratchet the battery density up to more than 300Wh per kg, raise L/D (cruise) up well into the upper teens, or assume the batteries make up nearly 3/4 of the empty weight leaving little for ....the airplane, or a combination of large improvements above.
What sorcery is this?
