Awesome, thanks for answering that. I assume that is because the SM-EW67A-E had the wires designed into the junction box vs. the new SM-EW90 not having the wires built in?
For the length of the EW-SD50, are you guys using 300mm length for the shifters? Seems like that should be long enough, right?
Junction A allows you to plug in the USB charger for charging the battery. It's more convenient than pulling the seatpost out.
So the seller of that eBay internal battery pack says:"This kit will charge the battery IN THE BIKE through one of the shifter ports, or you can buy a SM-JC41 junction box (not included, see photo 6) and charge by connecting to RD or FD cable."
"Charging instructions: To charge battery plug charger into bike before plugging the charger into AC outlet;
1 Plug charger into any open shift lever or junction port
2 Light on charger will turn green
3 Then plug charger into AC outlet light will turn red indicating charging
4 Within 60-90 minutes charger light will turn green indicating full charge
5 Unplug charger from AC outlet before unplugging from bike"http://www.ebay.com/itm/Di2-SEAT-POST-BATTERY-CABLE-KIT-FOR-ULTEGRA-OR-Dura-Ace-9070-Alfine-FITS-27-2-/300945651011?pt=LH_DefaultDomain_0&hash=item4611c23543
Is that different than the one that comes with the SM-BTR2 battery?
