I take delivery of my Tesla model S in two weeks time I'm super excited... I understand that charging the battery to 100% and discharging to 0% can damage the battery and that you should only ever charge the battery to around 75% for everyday use. I remember reading somewhere that the Tesla model S 60 actually has a 75 kWh battery and can be upgraded via software. If that is the case is it okay to charge my Tesla model S 60 to 100% ?? As it is actually a 75 kWh battery..
