Isolated dc/dc converter orion-tr 12 | 12 -30

I am adding a LiFePO4 Lithium Battery to a 2002 class c motor home. the only component I have is a isolated dc/dc converter Orion-tr 12 | 12 -30. My question is if I install the Lithium Battery will the Victron Orion converter protect my motor-homes alternator? I understand that a DC/DC charger would be better however I already have the converter.

Thanks
Dan
