I am in the process of completing the wiring design/effort on my homebuilt F1 Rocket and am "planning" on not using a battery bus, just a main and endurance buses. I'm using Z-13/8 (conventional mags), but don't see a need for a "keep alive" circuit with my avionics suite (not do I need power for an electronic ignition system). I see that other builders have put all sorts of things on their battery bus, such as flaps, clocks, etc. Since I may be missing something here, I'm asking: What does the "List" think ought to be on a "modern" battery bus and what rationale is commonly used to justify those selections, please...
Regards,
Lee...

I have a small battery bus for the 'keep alive' for the clock in my engine monitor and for a 12 voltv cig. lighter outlet which I use for the Battery Minder to maintain the battery in the hangar and accesories like my XM radio when flying. Happy with that set up.

My blade fuse-style battery bus has these fused circuits:
1) cabin dome lights
2) the N/O oil pressure switch which feeds the Hobbes meter
3) E-Bus alternate feed fuse
4) low amperage (15A) ground power which goes to the battery, of course
5) power for the over-voltage panel light so if everything suddenly goes dark due to an over voltage trip, I'll still have a clue what happened.
Any of those fuses could be handled by an inline fuse. I prefer having them securely mounted and organized on a fuse block where I can easily get to them. I have one more slot in the block, and will probably find something else to go there.

I'd put anything that needed "keep alive" power, and anything that you absolutely need to have running if you kill the battery master and alternator following a "smoke in the cockpit" event. In my case, I will fly IFR, so I need something to help me keep the wings level - I put my turn and bank on the battery bus. You want as little as possible on the battery bus, to maximize the chance that you can stop the smoke by killing the electrics.
Given your situation, I agree that there may be no need for a battery bus.

I also use a battery bus cigarette lighter receptacle for several
things. Programming handheld gps, blowing up air mattresses, powering a
small inverter for a soldering iron, dremel tool etc. It was really
installed to power handheld devices in flight after everything else was
shut off. I also put a switch beside the receptacle to kill it which is
handier than unplugging stuff sometimes. LED dome lights are also on
that circuit. I have additional cig. lighter receptacles that get power
through the batt master contactor.
