I have a used but in excellent condition di2 11 speed ultegra groupset with all the wires, juntion boxes and battery with latest software  installed.

Items include are:

Brakes BR-6800 rim brake. New brake pads

Front Derailleur FD-6870

Rear Derailleur RD-6870

Battery SM-BTR2

Juntion Box SM EW90-A

Cables

Brake Levers BL-6870

Crank FC-6800 172.5mm

Chainset

11 speed 50 34T

The groupset is perfect for an upgrade build from mechanical to DI2 all working with some minor age related marks. Please see pictures for condition. The item will be sent tracked, signed for, and insured for the purchase value.

Unfortunately, I have no charging cable for the groupset. These can be purchased on eBay for around £40-£50.

Ask any questions.
