Does anyone know the capacity of the Roadster's ESS? We know it is made up of 6831 18650-form-factor batteries, but there are different types and nowhere on the website does it give the specs for a single cell. I mean, an HR18650 cell can be 1300-1400mAh whereas a LR18650 can range from 1800-2200mAh. Also, it doesn't give any info as to how many of the 6831 cells are linked in series versus in parallel. I mean all 6831 3.7V cells can't be linked in series, otherwise you would have a 25275V pack!! I'd like to know the specs on a single cell...and the total capacity of the whole ESS.
