Lenovo X1-Carbon (G3) 14" i5 256GB Ultrabook

Does ANYONE have a clue as to the exact model number for this X1 Carbon? Maybe someone who already bought one of them? I wanted to see how much Ram it could support, whether it had 1 bank with a 4GB or had a pair of 2 GB instead? The other concern is what capacity 8 cell battery it ships with. When I looked on Lenovo’s site there were six main X1 carbons that started with the Type 20A7, 20A8 and had eight or more sub versions so I can’t get any real details. I asked Woot but got no response… Been looking for a thinkpad for quite a while but all I’ve seen were the T-450 which have either 8GB or 12 GB of RAM but were always refurbished. This says it’s actually new! Be nice to have a new system again, I just need to make sure I can get 12GB on board so It can run my editing software.

Thanks in advance if anyone can help!

X1 Carbon RAM is soldered, there’s no way to add more.
