How difficult is that? I guess what confuses me is I dont know what is doing the battery charging, the inverter/charger or the converter? If you leave the existing converter will it just not charge a 100% or will it damage the batteries by going in to float? Also what about generator power? Can that just be adjusted setting wise like the others?

Someone can correct me if I’m wrong but I don’t think you have a converter at all.
When you have an inverter/charger it takes the role of charging the batteries which provide your 12vdc power.
I’m planning on changing my soon to be delivered Isata 5 36ds to lithium.
It has a Magnum inverter charger and a BIM that I will have to change out to a LI-BIM. That is the only device I am planning on changing.
With a good lithium like Battle Born, Relion, or LifeBlue their built in BMS can handle regular chargers well. To get a full charge I will need to change the profile in the Magnum and the solar charger.
This assumes you have the same equipment in your 30FW.
In summary:
*change out BIM for LI-BIM (allows charging to/from chassis, alternator)
*adjust charging parameters in Magnum and Solar chargers
*pay attention to environment you place the Lithium batteries in, they shouldn’t get wet or charge when below freezing (check MFG specs) - some come with heaters built in
*make sure battery has a high enough discharge current to start generator when you pick them out (ask manufacturer), that is the only thing you need to worry about with respect to the generator
