I can’t answer your question, but the Pure3 system is detailed in Section 6-9 of the Operator’s Manual.
If you don’t have one of those here’s a link to a full PDF of that manual:

As Winnebago started getting into Lithium battery tech they first started partnering with both Volta and then Lithionics. The Travato models got Volta Pure3 systems. But then… Winnebago bought the entire Lithionics company and has been adding that system to their RVs.
I don’t know if they no longer work with Volta, but you can bet that Lithionics will get the lion’s share of their Lithium battery business.
The Volta Pure3 is a good system. You might want to contact them directly. That always seems to work best.

Plus there is a Travato Group webpage with operational info:

There’s more out there. Do a Google search for Volta Pure3 and you’ll find lots of resources.
