I'm connecting the Orion DC-DC Smart 12/12/30 to my lithium battery bank. Instructions show going from the starter battery to the DC-DC to the batteries. But, my alternator runs to a Pro Mariner ProIsoCharge1.3 then to the battery so i'm not getting much from the battery. Does anyone know a better, acceptable way to connect the Victron to get more power going to the batteries?
