Planning stage RV system. Preparing to order equipment (Need advice)

[Rusty.Watts]

Will be building a 24 volt lithium system to an inverter in a 40ft coach conversion RV. For the present time, I want to charge four 24 volt, lithium batteries with a generator & litium charger. (What watt size??) do i need to purchase? RV lighting is 12 volt LEDs & power is supplied from a 110 volt to 24 volt power supply. I have already wired for a my 110v needs. A Propane & 110 volt water heater. A refrigerater, 2 TV's & a cook top exaust blower @110 volt.

I started buying equipment 4 years ago befor I knew what my needs would be! I am sure im going about this wrong. Can anyone tell me how to size a lithium charger.. I am going to build my own batteries according to Will's advice!

Thanks

What generator? Too small is easy to overload. How fast do the batteries need to charge from low? 2hr? 6hr?
May as well post what batteries also. 50 Ah or 200 Ah each can make a big difference.
