I'm wondering if it would overlaod my battery to perform normal functions as well and provide heated glove and vest for me and jacket and pants for my wife. I know they all run off 12v but don't know if it's too much tasking for the battery
Hold on a minute, I missed the wifes clothing too. That's 4 items not 2 as I thought. That's quite a load for all 4 pieces plus the normal load of the bike. You may want to upgrade the alternator to a higher output of you plan on running all those items frequently.
