Question:
I am wondering if upgrading to a lithium compatible battery charger in my trailer how this will effect my trailer connector and truck alternator. I was not able to find anything in the manual about the connector. I know it seems to trickle charge our AGMs when towing but if I switch to lithium will there be any impact? Where is this controller for the trailer connector anyway? Is it part of the WF8955? Thanks!

When you charge your battery bank using the 12V power from your tow vehicle 7-Way it's going to be a trickle charge whether you have standard or Lithium batteries.
If you want your tow vehicle to actually charge your Lithium battery then you need a whole different setup like the Redarc In-Vehicle BCDC Battery Charger # 331-BCDC1225D designed for battery banks rated for 75 amp-hours - 200 amp-hours. This system uses a completely different wiring connector for 12V power so you can be confident they can handle the higher rate of power coming through the connectors.
We actually have a whole kit as part # e79ZR which comes with all of the wiring and connectors you need to complete this installation.
