No, I don't think this is the main issue, per se.
The point that all the electric 'boosters' seem to miss (or deliberately skip over) is that you don't jettison battery cells as they go flat, unlike any liquid-dinosaur powered aircraft which get lighter by the minute as they head to their destination.
Two other issues are that you have to carry "full tanks" (weight wise) on all your flights be it a short hop or maximum range.
Also, the glossy advertising brochures say as an example "one hour endurance", I'm going to bet that is from take-off to the fan stopping without allowing for weather, diversions or reserves.
What is the real-world, CASA approved, endurance compared to the advertising brochure endurance?
It'll be a cold day in Hell before electric flight is "Commercially viable".
