(a) eestor were not making the up/down converters
(b) LightEVs is a marketing company with no in-house design expertise
Other than promising everything to everyone as salesman like to do, what substance has this comment? And what additional size/weight will the conversion add to the envelope? Surely something serious customers need to know?
Of course, as exco says - at least this design job is doable (though maybe at size/weight that makes things much less attractive for two wheeled vehicles).
If LightEV is serious it will ahve to address these questions - and by more than just promises. As far as I know they have promised prototy[pes with all tehse qualities (and tehrefore including the up/down conversion).
Assumptions: 1) E=1/2CV2
