If you want to try out a cheaper option and not have to replace the charger, this little module should do the trick for lithium batteries:

I would've gone with this option, but my Iota charger has IQ/4 built into it and is not compatible with the dongle they sell. I wish it was not the case.

The newer fwc have the Iota with a built in module for AGM batteries.

Ahh, gotcha. Didn't realize iq4 meant agm specific

Can someone with that knowledge advise if this rudimentary diagram is correct?

All I am attempting to do is replace the battery with a lithium battery and the Iota charger with a Victron Smart Charger IP22.

Apologies for beating a dead horse here. I have talked to a lot of different electrical shops over the last 24hrs that tell the IP22 will work, but none are familiar specifically with FWC setups.

That IP22 charger definitely will work. I was planning to replace my Iota with one but then had second thoughts based on how seldom I charge from shore power.

I would not consider your drawing fully correct. You seem to be only drawing the positive routing, and you have mixed the AC circuit breaker panel in with the 12 vdc fuse panel.

The DC output of the IP 22 should connect into your camper just as the Iota did. Same with the AC input side, except you might want to install a 120 vac receptacle in the cabinet rather than cutting off the plug on the IP22.

+1 to what Jon R said.  I did cut the plug off of mine.

OP - is your camper a front dinette model? I ask just because that’s what I have and I’m familiar with most of the electrical layout in the cabinets.

Yes mine is a front dinette model.

Yeah my drawing was really to wrap my head around how power gets to where it's needed, not so much an accurate depiction of the actual wiring in the camper.

 

I ordered both the Victron Smart Charger IP22 and a Progressive Dynamics PD9130LV in hopes that one will suffice and can send back the unused one. Whichever one is easiest is the one I will use I imagine.

It doesn't IQ4 is a module.  Some of the Iota's have swap-able modules, others do not.  Whether swappable or not, the IQ4 adds the "smarts" to the iOTa.  Without it, they are a really dumb ACDC power converter/charger.
