Hylex Di2 Project Advice

[swaterfall]

I'm piecing parts together for a TRP Hylex / Di2 build. I've never built a Di2 bike and I would like some help with the parts I'll need. I think I'm going 1x11 for now so what I think I need is:

TRP Hylex (I have these already)
Di2 climber switch kit for Hylex

Di2 climbers switch, R600
Di2 cockpit junction box, SM-EW90
Internal junction box, SM-JC41
Battery SM-BTR-2
XTR Di2 Rear Der
Etubes for shifter to EW-90, EW-90 to JC41, JC41 to battery,JC41 to rear der??

and of course a charger.

Am I missing something?

TRP recommends the newer battery, BT-DN110.

The R600 shifters have their own built-in wire so you only need 3 e-tube wires:

EW-90 to JC41, JC41 to battery and JC41 to RD.

Alternatively, you could get the sweet SC-M9050 display junction instead of the SM-EW90. As shovelhd noted, if you're going to be buying a new battery get the latest BT-DN110.

I've got the 9050 on my Ellis with 785 levers and love it. Battery indicator is more accurate, on the fly derailleur adjustment with visual indicator, and no ugly rubber band around the stem (although you can get headset spacers with built in clip from 3rd parties).
