I 'just' purchased a Di2 kit and ended up needing the cylinder battery for the internal install, so I didn't end up using any of the parts listed below. The parts are compatible with Shimano's E-tube Di2 components -- Ultegra 6770 / Dura Ace 9070 and will work with an external install or an internal install but with an external battery mount.
They are all new in the box, never been used, but I have opened them. Offering at a discount to eBay. Will sell everything for $250, shipped. Will also sell the External Battery Mount (SM-BMR1-LB) separately for $100, shipped.
SM-BTR1: External Battery
SM-BCR1: Battery Charger for the External Battery
SM-BCC1: A/C Cable for the Charger
SM-BMR1-LB: Long External Battery Mount
