Sorry, I’m a little slow getting here with these photos of my setup.
A couple years back, my older AGM battery just quit mid-ride, 50 miles away from home. I kick started it and rode it carefully home. Caught two red lights on the way, stalled at the first but not the second, phew! Later considered that a voltmeter might be a useful tool to have onboard.
Also noticed that my older phone battery was pretty low in the latter stages of rides, so I added the phone mount and charging cord.
The practical value upgrade outweighs the aesthetic value downgrade, IMHO.
