Have set my 520 to show gear selection and battery level on etap groupset but only one battery level is shown, should there be two indicators as etap has two batteries?
The eTap has at least 4 batteries. One in each shifter, plus one with each derailleur. What the Edge is reporting is the status of lowest battery. When the battery with the lowest status hits "low" then the Edge will identify, which one it is.
