I have arranged for the AGM starter battery in our Ducato based motorhome to be continually kept charged at 13.4 volts.
I feel that this is better than the very low trickle charge current more usually found on modern motorhomes because AGM lead acid batteries are happier when kept fully charged.
I have chosen the lower AGM charge voltage rather than the higher voltage available so that there is some room in the battery for when the smart alternator kicks in during engine overun.
The lithium leisure batteries are charged with a Schaudt 121545 B2B fitted by Hymer.
This system seems to work well, but I would welcome any views from the collective.
