I am planning a new system on my boat powered by twin outboards, ideally my 2 aux batteries will be fed separately by the aux/isolator circuit from the stator in each outboard. This is not via the engine cables to my starting battery, that is a separate system that I want to keep separate. The stator maintains 14.4 volts output but adjusts current based on various factors, it also prioritizes the starter battery from what I understand. My thought is to go isolator circuit to fuse to buck boost in, to buck boost out to fuse to lithium battery with built in BMS. The battery specs give me what I need to program on the buck boost. My question is can I go direct from the stator with this, it appears to be how it's designed but all diagrams show a battery in parallel which I won't and don't have/want. Is there any other precautions I need other than appropriately sized fuses for the correct wire size.
