Hi I was recommended to ask a question regarding the charging of my gel battery on this forum. I have a gel 110ah under seat battery in my VW T6, which has a smart alternator. I have the 12/12/30 set to auto charge and on the pre-set for gel 1.
So what i noticed is the battery only charges when the alternator kicks in to top up the main van battery, this kicks in once the volts drop below 12.5v and then charges for about 5 seconds, at which time the Victron kicks in and charges my auxiliary battery, then the alternator drops out and stops charging and the Victron ceases. Is there a way to make the Victron charge even if the alternator is not charging the main battery in Auto mode. Or do i have to connect an ignition wire to get this behaviour to happen. advice would be great. thanks
