Please find attached overview electrical diagram with all Victron elements listed.
We used Cyrix battery combiner. We believe that it would be OK to connect mixed batteries: Lithium house battery, when charging, to starter and thruster AGM batteries. When engine alternator is charging the starter and thruster it would also charge the lithium house. Would there be any real advantage in using bi-directional DC-DC converter instead of the combiner? As we will have 1Kw solar panels and generator the engine alternator will be used only occasionally. We may not even need to connect the starter and thruster batteries at all but see it as advantageous as a back up situation on ocean crossings. I guess, this is the question to Victron expert.
