h-bat in e-scooters

1. H-Bat Potential in Electrical Scooters
More E-scooters are being sold because cleaning of the cities in noise and pollution and because of the banning of cars, so
alternatives like the scooter as straight forward.
The comparison is made to the iconic Italian Scooter brand Vespa and its electrical version Ellectrica, which is currently Li-
Ion Powered.

(*) This is an estimate as we could not find the dimensions, for Li-Ion there is an average of 2.5 weight to litres ratio, so
1 litre weighs 2.5 kg
(**) We assume only 80% of the total battery volume is battery, the rest is auxiliary
