Does anyone know if its possible to upgrade the capacity of the Model X battery, and range of the car. I have a 2016 October built car with,(I am guessing here based on DOM), the older 18650 type, model 90D. I have been reading upgrade the 20% density upgrade of the the more recent 2170 battery and was wondering if maybe the newer baerties could be fitted or if a higher density 18650 battery may exist that would allow a 20% increase in range?
