I want to upgrade my batteries without jumping to a genesis dual battery system. I've heard the stock one's blow and I've had the ess warning light a few time's in the sub zero weather. I run a dashcam and suspect it may be draining batteries. I have a 2021 2.0 with the towing and cold weather package. Problem I'm having is finding out what size my auxiliary battery is without doing a dismantle of the battery tray. I know my main battery is a group 94R/H7, but I can't seem to find an aftermarket vendor that has a listing for 2021. Can it be looked up by vin # ?
