Hi, I have a 110ah AGM hab battery, charged via a CB-516 and DS520 distribution box in my 2009 Rapido. Also a Victron smart solar regulator (120W Solar panel) charging it with a Battery Master managing a trickle charge to the veh LA battery. I have acquired a good condition 110ah LA leisure battery and wondering if I can connect it physically next to the AGM in parallel with my AGM battery without issue. I would ensure both are fully charged when connecting but concerned at the potential mix of chemistry... Will appreciate your thoughts please.
