I'm looking for a maintainer for 2 batteries that are connected together.

I have a small camper with a starting battery, and a deep discharge (house) battery (to run things). They are connected via a Yandina which is a solid state switching device.

The battery tender jr. and other 2 maintainers I have aren't able to charge both batteries.

I'm thinking I could a big powerful maintainer that could be plugged into one battery and keep it charged enough that the Yandina would open the gates to allow charging current to flow to the other (house) battery.

Any ideas?
