Really? I would have thought the 3 down sides to electric planes would be refuelling infrastructure. Sensitivity to cold, and limited range.

Most of these planes are used as puddle jumpers in the first place: they aren't used because of the long distances involved, they are used because of terrain. Refueling infrastructure is pretty easy (Alaska has grids, A LOT of localized hydro).
