Following the cold weather and putting the charger on the bike when the voltage dropped to 139, I noticed the charged standing voltage is lower than last fall. I charged the bike and saw voltage of 144v but it dropped off to 140 shortly after the charger stopped.
I decided to run the battery down a bit to cycle it a bit, I did notice more sag and reduced range.
It looks as if I will have to dig in to the battery and see if I have a bad cell or 2. I have a lot of spares but had hoped I would not have to take it apart so soon.
I still haven't installed the new trunk, too many projects and too little time, maybe when I have it down for the battery service it will get done.
