The A pack was the original pack June 2012, it's limited to 90 kW at a supercharger
The B pack started being delivered early 2013, it can be charged above 90 kW (120 kW)
The C pack was never delivered--at least I know of no posts showing a C pack
The D pack started being delivered in 2014 (not sure when)
The E pack started being delivered later in 2014 (not sure when)
For the last two, the differences aren't known. Perhaps different contactors???

No one can give you a definite value as to the chance the car you are looking at has a B pack unless they have access to the car and can look at the label on the pack just behind the right front wheel. It could have an A pack or a B pack.
Ask the seller to send you a photo of the pack lab,e, or go see the car if you can.
Wait, what? Your March 2015 85D has a B battery? Shouldn't it have a D or an E battery?
The revision #'s for the 60 kWh packs are different from the revision #'s for the 85 kWh packs. That's true for any two different Tesla part #'s. There's evidence that Tesla tries to keep refurb part # rev's in sync with new part #'s on the battery packs, but the 60 and 85 rev's aren't comparable.
That can also be true for the dual-motor packs vs. single-motor packs. They have different part #'s so they can have different revisions (although - again - it seems Tesla might be trying to keep them paralleled).
That sounds like you got a recycled battery pack....it's possible during late stage build or pre delivery they found a problem with your new pack and replaced it with a refurbished one before it was delivered to you.
A new car will come with a new pack - even if there's a bad pack during build or delivery, you'll get a new battery, never a refurb.
But whose got a B pack on a brand new car?? I thought they were all D packs at least now.
