Hey folks--
Context: New-to-me skiff. Have a cranking battery that's good, and works. Figured that part out and the 50 HP Yami 2-stroke is good and was serviced and tested personally.
The rub: Switch power to "battery #1" which powers the bilge, depth finder/gps/fishfinder, running lights, and baitwell, on my 2 batt switch comes from the starting battery. My gut says it likely is not wise to run the ship on a solitary battery without a house. My time in the military and as a scuba diver (and life in general) go along the adage "two is one and one is none."
Secondly, my question: Is it okay to share a trolling motor battery for the house battery? The house would be a 100 aH LifePo4 12 volt for the following:
I have been reading on Blue Sea Systems recharging offerings on two battery set-ups (even if different battery types) and of course our buddy @iMacattack with New Marine switches, lines, and educational materials which has been REALLY educational.
Given the above, is sharing a 12V "house" trolling/bilge/gps and fish finder/occasional running lights and rarely the bait well a good plan? I do have a switch already installed in the center console with battery off position, battery 1, battery 2, and both positions, the typical; yet I anticipate a full rewire this winter. For this season's use on my new-to-me skiff, I'm thinking of using the LiFePO4 12 V for the bilge and fish finder and troller and thinking on the rest 'til the cold months arise.
I'm not above an "on/off" switch in the interim (with in-line fuse) for bilge, troller, gps/fish finder. Cranking only to engine.
Obviously, I'm not an electrical engineer
Any recc's or thoughts would be helpful. Oh, and what wire AWG ((I understand tinned copper) should I run with for bilge versus depth finder? Depth finder separation from house would be 12 V @ 10 feet max, otherwise, all house items run 10 feet to bow where the 100 aH 12 V LiFePO4 battery will reside so the gauge wire will be less than 5-8 feet.
thx Folks!

- 12 V trolling motor and GPS/fish finder primarily
- running and anchor lights (rarely)
- bilge as needed (moderately? occasionally?)
