Here is my wiring diagram for installation of a 314 AH WattCycle Mini Bluetooth Lithium Ion battery keeping the stock Hitachi Alternator. I realize this is suboptimal but I think at the moment that is what I'm planning on doing. Lets not get into a debate on going to a externally regulated alternator right now. I am only asking the experienced forum members to give me their feedback. This is based on MainSail simple diagram with a Victron XS DC to DC charger. All switches are simple BlueSea ON/Off (not 1-2-Both) switches. There is also an Emergency X-Connect to start the Generator in the case of a Start Battery failure or to power the DC Panel in the case of a House Battery failure. The Grounds are shown simplified - all go to the common ground buss.

I'm showing MainSail's diagram first followed by wiring diagram. They layout on my drawing draws from Rod's diagram and the locations on my specific boat and wanting to keep the loads with the potential for large inrush currents normally run from the start battery. Have at it with comments. I'm open to suggestions.
