I have a small boat which I am setting up with 2 x 12v batteries for an electric trolling motor, fish finder and a tilt and trim unit.
The previous owner had the batteries set up in series to provide 24v for the trolling motor. The fish finder was connected directly to a single battery for 12v power.
Now I am introducing a tilt trim unit for the outboard which requires a 12v supply.
The current setup has fuses.
What would be the best way to set up electrics with the three power drawing devices?
