Lithium batteries and alternator protection.
The six 6 volt lead-acid house batteries in my class A DP have gone bad. I am looking to replace them with 6 Battleborn 100Ah 12v LiFePO batteries. Eventually I will be adding solar. I am not look...

This is the 30A unit they list. Is that the one you have?
Not sure what that non-isolation means. One of the reasons to use a DC-DC is for isolating. OP take note for operating with LFPs! (The Renogy ones do isolate, eg).
It says its output is 30A at 430w so voltage is 14.3. That is too low for many house battery specs, but would work with LFPs. (Renogy ones can do 14.7v for some profiles) A worry with LFP is the two-hour abs time, but it says you can change that time (20 minutes after reaching Vabs is about right).
It says it is 87% efficient, so at 430w out, that is 494w input. Pick a number for input volts. EG 14v would make that 35 amps draw at the charger end of the alternator/engine batt wires
IMO the OP might want to look at other models of DC-DC. Be good if others on here would comment on all this for their brands and specs.
