Lithium for 2021 23FB International

Keeping in mind that I want to keep this simple, what would I need specifically to upgrade to two Lithium batteries to be charged from a car alternator, occasionally a Honda 2200, and one rooftop solar panel?

1. Will two Lithiums fit inside the existing battery box?/ What's the highest wattage batteries I can cram in there?

2. Presumably I'd need a solar charge controller--where to place it?

3. Can the voltage on the existing 1000 watt Vitron inverter/charger be turned up to 14.3 to avoid replacing it?

4. Is the factory solar pre-wire kit sufficient?

4. What other devices or wiring is necessary?

We took delivery of a 2021 Globetrotter 27FB. We added (2) Renogy 170amh lithium for a total of 340amh. We also added 540 watts of solar on the roof and have a 200w solar suitcase. The moot inverter charger went near the batteries in the storage area behind the batteries in the trailer and although I hated to loose that space, we have enough left over for plenty of storage of wheel chokes, water hose, etc. the system works great
