[QUOTE="cairnspom, post: 250462, member: 4645"] Sorry should have been clearer, the 3rd battery is the engine cranking battery, unfortunately I can only fit a 80ah battery as the 'first' auxiliary under the bonnet due to size constraints, but need the capacity of the 120ah to run the camp. that is why I am worried about charging batteries of different sizes, in different states of charge. The 80 could be fully charged while the 120 may be down 25%, and with them both connected to the dc/dc charger I am worried I may risk overcharging the 80 [/QUOTE]
