Battery weight in there stated at;
The website now says Alice will cruise at 220kt (407km/h) and have 440nm range, with power coming from an 820kWh lithium-ion battery system weighing 3,720kg (8,200lb). Previously, Eviation has said Alice would cruise at 240kt and have 540nm range and 920kWh battery system weighing 3,600kg.
Some sort of deal with DHL where 12 will be used on freight runs as a test bed.
DHL plans to build the world’s first electric air cargo network with the electric plane, noting that Alice can be flown by a single pilot and will carry 1,200 kilograms (2,600 lbs). It will require 30 minutes or less to charge per flight hour and have a maximum range of up to 815 kilometers (440 nautical miles).
By my calculations that leaves just over 2000kg for the weight of everything else, structure, fittings etc. 7500kg MTOW - 1200kg load - 3720kg batteries - 400 kg powerplant = 2180kg left over for structure, fit out, etc. It sounds feasible, but tight.
I was wondering why the engines had air intakes, turns out the electric motors are liquid cooled.
