Isolating a non lithium compatible WFCO converter when upgrading to lithium

  This is my uneducated take on this subject. We have two Victron 100/30 solar controllers, a Victron shunt and a Victron stand alone charger. All smart devices. Being networked, they monitor each others voltage and optimize charging from each source. Since the WFCO is not part of this network, any charge coming from it can be misinterpreted as battery voltage and confuse the Victron network. This could affect the charging mode of the Victron devices. The system will still charge with the WFCO connected but at a reduced efficiency.
  
  edit to add that this is not from an AI search, just what's floating around in my head ... probably not a good source

  I don't trust AI to provide information. You need to follow the links that are the source for any AI-provided information in order to evaluate the credibility. Often, you'll find its just bad information. Frankly, there's no credible reason I've seen to worry about bypassing the WFCO converter. I use a standalone Victron charger or our Victron solar set to lithium settings to fully charge a 100AH LiFePo retrofit. The WFCO doesn't error or complain when the higher lithium charge voltage is implemented, and on its own our "never detect" unmodified WFCO will only charge the battery to 80%, which is the ideal storage charge for the battery when I have the trailer covered for the winter.

  Same here.  I have the non-Li WFCO, Victron Li battery charger, and Victron Solar charger (Li mode) all connected in parallel and have had no issues.
