I'd like to be able to charge one lifepo4 battery (that may be at a 75% SoC) from a second lifepo4 battery (that may be at 50% SoC). So the battery with the lower voltage will be providing energy to the other battery.
I believe the Orion Tr Smart may be able to do this, but only if I disable Engine Shutdown Detection - is that correct? Any other non-default settings needed?
Could the Orion Tr (the non "Smart" version) also do this? If so, does it need non-default settings / programming to do so?
Is there a different Victron product that I should be looking at?
