Di2 Upgrade kit

Can anybody outline exactly what I need for an Ultegra di2 upgrade.
At the moment I know the below:
STI Shifters,
Fr Mech
RR Mech
Battery + charger
Long mount for battery
Junction box
4 cables
If I've missed anything let me know.
Also if you have a groupset for sale let me know and I may take all of it.

Best to buy an upgrade kit from somewhere like Merlin.
Depending upon internal or external, you need either sheaths or internal anti-rattle kit.
