Cable is cheaper lighter and works fine.Battery power is trying to fix a problem that's not there.Wiggins didn't look too pleased when he's battery went flat mid stage in the tour that's for sure!
Thanks for your comments they have been helpful, i suppose it will come down to price and i agree, coming off your bike becomes more expensive the more money you spend on the gear you put on it.
Recently purchased a new bike and went from Ultegra di2 to Dura Ace di2. There IS a difference, it runs smoother than Ultegra but shifting isn't noticeably different as di2 makes it pretty much perfect. The only issue is the creak from the carbon spider on the cassette which a lot of people seem to have.
Crashing on DA DI2 is much, much more expensive than on Ultegra, as I've discovered twice in the last few weeks. Ultegra DI2 is about half the price. Haven't ridden it but I can't believe the shifting is anything other than excellent and doubt that you would be missing much in terms of performance. Ultegra is heavier than Dura Ace, but if you were worried about weight, you wouldn't be on a Cervelo S5
