I tried to edit but I guess it was expired
Update :: according to ElectroSport article which I found on Bing search , my charge system is fine.
2500 rpm voltage across battery is 13.58 V
5000 rpm voltage across battery is 14.04 V . According to the troubleshooting flow chart everything is fine.
Oh and I did attach the Tender adapter nicely tucked away for the future. I'll use it if I know my bike will be sitting longer than 4.5 days / especially with low hours on it
