You better get that clarification from Oliver and Life Blue. My interpretation based on the warranties online there is no warranty. The limited parts warranty covers this RV for a period of two (2) years from the date of purchase by the original retail purchaser. The limited warranty covers manufacturer's defects in material and workmanship on parts manufactured and installed by Oliver. 6. This Limited Warranty does not cover batteries sold by LiFeBlue or any authorized distributor or dealer to an Original Equipment Manufacturer (OEM). Please contact the OEM directly for warranty claims.

It’s all about more storage.

I don’t see how anyone could recover the cost of the lithium batteries.

The end of this video shows separating an ABS flange.

“IF” the Oliver folks advise the flange can be removed without too much grief, I d opt to replace with a Sioux Chief flange. There are websites suggesting the RV flanges removal is not difficult. RV Toilet Flange Glued to Pipe Depending on your RV model you may run into a toilet flange that is glued or cemented into place. You do not have to worry because breaking that seal is not that hard to do. All you will need is a good chisel and a solid hammer. Just place the chisel between the flange and where it is glued to and give the chisel a good firm tap. The seal should break without causing any damage.

Possibly sealed with waterproof marine sealant or silicon vs solvent welded. https://www.oatey.com/products/oatey-level-fit-closet-flange-plastic-ring--1609630392
