We got delivery of our S85D at the end of March, and today I just checked the battery pack version. It looks like I have a B pack. I though B packs were very old by that time, and that they were on later pack versions like D and F. I have attached a picture below. What do you think? Our car also had some other strange things like we got the old "blue" LED's while the new softer "yellow" LED's had been being delivered for a couple of months. Don't know if there is anything to read into there.
