Battleborn in propane tub?

BandB

We own a 2022 320s BD and recently purchased a 100 ah heated Battleborn lithium battery to replace the stock lead acid battery we have in the propane tank tub. As I'm reading posts here, it looks like everyone puts their lithium battery inside the T@b.  We're getting ready for a MN to Grand Canyon, Arches, etc. trip. Do we have to squeeze the battery to an inside spot and do all that wiring? Or can we just drop it in to the space the lead acid battery was in the propane tank tub? We already have a Victron shunt in there with a bus bar. If that's possible to do, then do we just move that little tiny switch in the fuse box area to "Lithium"? I've read so many of the posts, but most of it sounds like Greek to me.
Thank you for any guidance you can offer.

I placed my Battle Born battery in a battery box in my front tub in my 2018 320S. I didn't have a smart shunt. You'll want to ensure your WFCO converter is correctly charging for a lithium battery.

You will be all set with the Li switch. 
Many of the posts on this topic are related to WFCO models that are supposed to "Auto Detect" the battery type.  In many cases it does not detect Li batteres and one of the potential causes is the long wiring from the interior converter to the front tub.  Your switch assures the right charge profile is running for the battery type you select.
The Battle Born Li battery will be a noticeable improvement in 12 volt system performance and reliability.
Have fun!

Many owners just have the batteries in the tub and call it done, lithium or otherwise. 

There are a lot of posts here about running the various cables to the "inside" of the Tab.  In the last couple of years, owners have come up with slightly easier ideas of running the various wires under the trailer and into the areas behind the benches.  This seems to have made the wires much easier to run. 

This is one thread that shows how an owner did this with a conduit above the coroplast cover under the trailer.

These sorts of discussions do get pretty esoteric..but lots of help is available if you want to attempt this or you have an RV tech with the appropriate skills. This is just one example, there are probably a few more.

If you don't want to do all this to bring the battery inside, the only thing you need to check to "drop in" the battery is just to confirm the size of it.  Measure out the space your current "Group 24" battery is located.

The next step is to set up your Victron solar controller and Victron Shunt for the proper settings for lithium batteries.

If you happen to have the "Lithium Switch" model of the WFCO....just flip the switch to "LI".  This thread shows the "LIS" model of the WFCO (meaning "lithium switch).

This Battleborn page shows how to program the shunt for your Battleborn. (This would be the procedure for almost any battery, as long as you use your specific battery numbers).

This is the important setup procedure for the Victron solar controller.

You can put it in the front tub. Remember that it doesn't necessarily have to be put in a vented battery box. I used a plastic file folder box. You might want to consider coming up with a way to lock it up.
