Sorry if this has been asked before, did a search to no avail....

My Di2 Stopped shifting on the front today about 20 miles from end of route. However, I'm still ~50 miles from home/my charger (to do tomorrow...)

Any idea if there is enough juice to get me home on the 1x11 set up (more than enough gears for me to plod home...)

(no LBS near - there is one 25 miles away - but that would be a detour I'd prefer not to make....)
