Bike in storage over winter and no access to electricity and my CK charger, I keep a good 2nd battery at home being maintained by my charger, Is it ok to make up a lead and connect to that battery and fit a Din plug to the other end, then plug the Din into the Aux socket, then remove the bike battery for charging at home, all this parlarva because I don’t want to lose any stored info including Service interval, Will this work or does anyone have a better solution? Thanks guys.
