lithium question
Can you charge lithium batteries with a regular charger or do I need to buy a special charger?

You can keep your FLA bank for normal RV work (furnace etc) and also get an LFP for the microwave, kettle, toaster, and TV work.
That way you don't need two LFPs to get enough AH for furnace plus MW, etc. The one LFP can run the MW etc, leaving enough AH on the existing FLA bank for furnace etc.
No wiring changes or converter changes.
The LFP goes anywhere you can stash it inside where it is warm along with its own inverter (needs some air for location) On arrival camping, run an extension cord from the LFP's inverter to outside where you can plug in the shore power cord to the extension cord.
You recharge the FLA bank same as now. You need a portable charger to top up the LFP as required. Or use your converter with jumper cables over to the LFP. put them away after.
I have this sort of set up in the MH for the winter camping off grid. The existing MH set- up is the same as in the Profile, but have moved the two SiO2s (you would use one LFP) from the TC to inside the MH (on the floor behind a chair) with its own inverter connected to that bank.
I run the TV/DVD off that bank to keep those AH off the 6s, which gives them more furnace time. The MW etc can be run off the inverter on the 6s as usual, but I could plug all that into the other inverter.
In your cases, you would do it with the MW's inverter on the LFP and camp as usual off the FLAs for the other loads.
Big lesson I learned with the TC and one 100AH SiO2 (would be the same with one 100AH LFP) is it can run the MW just fine with the high amps, but you still need AH for furnace etc. which means you need 200AH.
The idea here is to save money by keeping your existing FLA bank to do the furnace etc, and now you can do the MW etc with just one LFP. You don't run the big stuff very long, so you don't need a ton of AH--just the high amp discharge the LFP can provide.
Note in this scenario the converter is not on the same bank as the inverter so no loop issues plugging into the shore power cable.
