PD 9100 AL converter/charger.

I purchased the new two stage PD charger for two new Lion Energy UT 1300 lithium batteries. I also bought a Renogy DC to DC converter to protect the chassis battery.
I have read that the PD can be installed as an auxiliary charger keeping the WFCO 8955 but I can’t find that information again. I have an outside outlet that I could extend inside to plug the charger in. But I’m unsure of the wiring from the WFCO. Seems I would need to connect the charging side to the batteries but keep the converter side connected to 12v load. Apparently it’s safer to run existing 12v through the WFCO at standard voltage instead of feeding 14.6v. The batteries are not in yet so I can’t experiment until they are delivered.

    Get rid of the WFCO. The new charger is rated at 60A so place it as close to the batteries as possible with adequate wiring fused as needed based on the distance. This is the primary consideration, then wire in 120V as needed.

    Extremely doubtful that the wiring from the WFCO is adequate for the new charger.

    Suggestion: Research and understand wiring loss. At 14.6V and 60A inadequate wiring can easily result in excessive voltage drop. And this is directly related to the wire gauge size and distance.
