You can't charge your scooter battery at the same time you are riding it. One reason why this can't be done is because scooter battery needs to be fully charged before they can be used. If by any chance you undercharge, it will cause battery failure. Another thing is because you will have to remove the battery from the scooter in order to charge it.
