Di2 Battery ??s
About a year ago, bought a complete Ultegra 6800 Di2 groupset for a build that has not happened yet. Do I need to do anything to maintain battery or is it fine in the box and on the shelf?

The first place to look for anything related to Shimano is the Shimano Technical Documents website.
Manuals & Technical Documents
Your best bet is to find the dealer manual for your system and see if it contains anything about long term storage of the battery. It might not, but it might.

Well, I'd make certain that nothing was plugged into the battery while in storage. Most rechargeable batteries appreciate an occasional maintenance charge, as they do self-discharge over time.

don't try this at home.
It's best not to keep it discharged or fully charged.
Dinotte lights told me to long term store their headlight battery packs at about 7.8v. Fully charged, they are 8.4v.
I'm not sure if you can just plug in the junction box with the usb connector to the battery and charge it. It's possible it needs the shifters and derailleurs configured too. And the battery level lights work from a long press of one of the shifter buttons, anyway.
Try the battery, a connector cable, and the junction box. See if the free E-tube Project software shows a charge level when the charger is plugged into the PC's USB.
