Charging lithium batteries with solar
I've got lithium camera batteries and a lithium jump starter battery pack. All charge via 12v auto circuits, i.e. they have their own chargers, they aren't bare batteries. They all work up to at least...

I wouldn't try to charge those little batteries directly from the solar panel/controller. If the sun goes behind the clouds or a shadow falls on the panel, your charging is interrupted. Those chargers should have a constant current so they can properly slow and then stop the charging process for the small batteries. Imagine if you were to plug a camera battery charger with battery into a wall outlet, then pull it out of the wall and plug it back in at numerous random times during the charging cycle.
Attaching the solar setup to the RV's battery and drawing 12V off that battery would be much better.
As for why the controller is not sensing the panel's output, not sure... maybe insufficient current for the controller's specs? Or a bad controller? Or it isn't sensing a complete circuit on the output side?
