Hello all, I have contacted a number of Tesla Employees, including Service Store Managers, and answer is always the SAME from each source. Apparently, at this moment, their are Technical and Software reasons that a 60 cannot be upgraded to a 85. I was told the connections/hardware pose a compatibility issue, as well as the software was not setup for it. Obviously, I am not able to undertake the task of dropping my battery to see the connections, so I cannot match with photos that I have seen on the 85kw battery packs. Anyone hear different from a TESLA EMPLOYEE (not rumor from 3rd party)? I'd like to hear input, as if I could upgrade to the 85, I'd do it in a heartbeat!
