I've never swapped cranks or BB on that bike so don't know if there's a hole from seattube to BB shell. (I'll read this: http://forums.roadbikereview.com/specialized/converting-di2-specialized-owners-318129.html)

http://www.wiggle.co.uk/shimano-dura-ace-9070ultegra-6770-di2-wiring-junction/What about a fork steerer mounted battery? That possible? Easier/harder? I could ditch or cut the top cap to allow cable to pop out the top, then it's near the stem-mounted Junc A box but I guess I'd then need to locate Junc B somewhere still and it requires a long cable run probably down the downtube.
hippy-
If only there was some system available which didn't need wires and mounted the battery directly on the dérailleur...

I have seen an externally routed non di2 lynskey at my lbs (clevermike) with that under bb connector. battery was the old version and cables routed under the downtube, but all in all looked very neat.

No experience with steerer mounted options. And yes that is the connector.

I run external cables for all but the battery. I used the bottom bracket drain hole to feed the cable to the battery (the hole was small so had to cut and re-join the cable), there has to be a hole from the bb shell to the seat tube of course.
Cables use the external connector (jc-40?) since neither the drain hole nor the cable guide hole are big enough to take more that 1 cable an I think the holes to the seat and down tubes are too small to take the internal cable connector.
External batteries are still available. Just not as neat.
