Di2 owners: Checking battery percentage and charge?
Outside of having the EW-WU111 wireless unit (which I don't want), is there any way to check the exact battery percentage? I know you can gauge the level by checking the color on the junction box (i.e. solid green for full, etc), but is there a way to know the actual percentage number through the program or through some other means?
Also, dumb question, but when it's being charged, there's an orange light indicating that it's being charged. Once that light turns off, I assume that means that it's fully charged, correct? It's not suppose to turn green or flash or anything like that?
