Do you use a trickle charger at home? Asking because I almost screwed up my battery. The day I got the bike I hooked it up to my existing battery tender. A couple hours later I was in the house reading my manual and realized a lithium battery came with the bike and I couldnt use my existing battery tender. Was only a couple hours so I'm not too worried. I bought a lithium capable charger. No issues with my battery, however my temps have been like 65 degrees at the coldest (also in SoCal).
