Welcome from Ohio. I use a battery tender in cold temps and never have any issues. It was 24f/-4.4c for the ride this am, looks like that will be the end of riding for a while because the forecast is 8"-12" of snow for the next 24hrs.

Just a suggestion maybe you need to fit the excellent and popular Eastern Beaver H/Lamp relay give ya bike a bit more battery power on the crank handle
