How about an extra 250 watts for 30 min?From another thread:“It produces between 50 to 75 watts for about an hour and a half, does 150 watts for an hour and in its highest setting, produces 250 watts for up to 30 minutes."Batteries can be hidden in the frame or in a water bottle.http://cyclingtips.com/2015/07...eg-lemond/

I doubt that these would give you enough assistance for a time trial to be worth noting, but an extra 100 watt for just 20 seconds during the final climb may be enough to distance yourself from the the other riders on the final climb.
