Lithium batteries and new solar charger
I am replacing my 4 6V batteries I think 2 lithium, have never been impressed by the 30A PWM charger for my 600W solar, probably my fault for using 8 avg wire on a 9m run. Thinking if I get a Victron ...

Ok the Op has a clue!
Yes the high discharge rate, the low weight, and the many life cycles are all worth something. Also no sulphation on solar while not getting to full every day. Watch out for high temps in the Oz interior with LFP AFAIK.
OTOH I can recharge my 460AH bank at 30% charging rate no issues though, as long as I have enough amps worth of chargers and a gen to run them along with anything the solar is doing at the same time.
Check out the Renogy DC-DC charger that has a buck/boost for the voltage for your alternator charging. I have the 20 amp size for my TC rig, and it can be set using its dip switches for various types of battery. It has a whole setting thing for LFPs, so that should solve that, regardless of your up and down alternator voltages.
