It looks like that's where he's got his camera pointed. When I had my Model S inspected at tesla, and they pulled the battery, they tore half of the label off. It's not hard to believe that the label could have been torn off by something. Sure looks like it.
What I would like to know is how you can get the info on the battery via software. The local guys tried to get into service mode to check, but they were pretty clueless. I haven't looked yet. Anybody know how to do that?
