Help needed external 200w solar panels

[Benz862]

Good afternoon everyone. I bought myself a brand new 2022 Jayco 166FBS, it already has a solar panel on the roof which I think is 190 W. In a few days I will be receiving two LiFePO 4 batteries that I will replace the lead acid battery with at the front. Has anyone done a replacement with lithium iron phosphate batteries? Also has anyone used the external solar panel feed to charge their batteries? Any advice would be greatly appreciated.

I assume the panel(s) are on the roof and the battery is on the tongue. Somewhere there has to be a battery controller. Probably inside a storage area near the tongue. Find it and using the model number get instructions. There should be a setting for lithium batteries and I assume yours is set for lead batteries. Look up MPPT and PWM solar charge controllers to read up on how they work.

You may also want to relocate the batteries inside somewhere. Look at many posts on doing this with the search bar above.

Thanks so much. I will take a look first thing tomorrow!
