Hi, I'm new to the forum (and motorhomes) so I hope I'm jumping in at the right place. I am replacing the original batteries with 2 lithium 100 ah and plan to wire this as per the attached diagram. So far I've disconnected the original bim as I'm putting in a DC-DC charger and I replaced the converter with a WFCO WF-8950L2-MBA for lithium batteries. Just wondering if anyone has any comments or suggestions on how I am planning to proceed and secondly if anyone know what the 100 amp breaker under the steps if for? The diagrams I've found seem to indicate it goes to the generator? I though the generator produced AC and the converter feeds DC back to the batteries?
