different types of packs?

[AZbba]

So I recall reading something awhile back that mentioned there were a few different types of packs in the model S's. I believe they were different letters?

Does anyone have more info about the different types of packs, which ones are better/worse and how to tell what kind you have?

Look at the wiki. There's a battery table. A packs in the 85kWh flavor are limited to 90kW max at the supercharger...
