I just messaged the guy and he said that the dealer told him that it was a 30kwh pack (under warranty replacement) they put in his 2011, but not everyone is telling him that there's no way that this is the case. Hopefully we can get him to confirm with Leaf Spy that he does indeed have a 30kwh pack in his 2011, which would clearly mean that there is no backwards compatibility issue and Nissan is "choosing" to keep the 30kwh pack out of the hands of current owners. If this is the case, it is a total shame because its driving our resale down, taking cars off the road that have longer lives, and overall contributing to more environmental waste as a result.
