Lithium battery swap

Hi
I have a 2017 Venetian A-40. Would like to swap out lead acid batteries for lithium batteries. Would like to know if I need to change anything or if the inverter charger will except these batteries? The control panel list lead acid Agm and agm2 but says nothing about lithium.
Thanks

If your charger has battery-type settings but they don't include Lithium it won't keep them charged above about 70%. You could add a separate lithium charger in parallel which would keep them at 100% and the inverter charge would take up the slack when they got too low.

At minimum, changing to lithium will require settings to be changed in your inverter charging system provided it is capable of handling lithium batteries. Lithium requires a different charging rate. Also, if equipped with solar panels, it will require changing the settings on the solar controller if it has that capability.
