So I was thinking to make the most efficient use of the range extended, that it might be a good idea to have it cut off as soon as the batteries are fully charged. I'm not sure if this is already done or not. Would this constant charging and discharging during range extend mode result in deminished battery life? Will the range extended be able to charge the batteries fully while meeti g the demands of the vehicle? I'm hoping this has already been incorporated, but thought I'd make the suggestion just to be sure.
