Imagine a vehicle that can cruise at 87 mph, for eight hours, on a 220 pound lithium pack.

It is extremely aerodynamic, and half the weight is battery. For comparison, I think about 43% of the 2013 Zero S ZF 11.4 is battery. The video's are great.

What kind of batteries are those?

100kg and 25kWh?

"high energy density Li-Ion batteries providing the rest of the 2.5 kW of energy needed for horizontal flight. These come from Panasonic and weigh only 40 kg. They are, says Gologan, much more like consumer notepad batteries than automotive 'and are of extremely high quality.'"

Automotive to me means prismatic (excepting Tesla). So perhaps these are Panasonic's NCR18650B cells.. should be about 100kg of cells for 25 kWh.

NCR18650B

Nice cell, 250Wh/kg. I'm surprised i had not heard of it. Probably because it doesn't have a very high discharge rate. But in this case it's not very important, since they only use 0.1C at cruise, and less than 1C at peak power.
