What do we know about the batteries? - there's a 60kwh option - there's a 85kwh option. - they where supposed to introduce a proper 40kwh version, but they didn't. Lucky bas'ards got themselves a 60kwh. ;-) - it uses 18650 cells. - Its a flat pack with coolant - but the package itself is the same on both versions. Could we try and collect what we know In this thread? I'm on a mission with this - but until I got some more info, Im unsure of the results of my Mission. What are the cells rated volt and kWh? What is the curb weight of a 85kwh Model S? What is the curb weight of a 60kwh Model S? What is the curb weight of a performance S? What is the chemistry used (what do we know about the mix?)? Feel free to add any other information that will be useful. Thanks!
