... This phase being the most critical, the main constraint is the one imposed by the batteries. Still heavy, they require a drastic reduction of the weight of the rest of the plane, so as to optimize the whole energy chain and to maximize the aerodynamic performance provided by using a high aspect ratio wing with a low-speed profile. With an energy density of 240Wh/kg, the lithium polymer accumulators weigh 400kg, or more than ΒΌ of the total mass of the plane.
Batteries it does have.
