EVE LF100 $75-85
Stacked 3 high for 300ah it would be a box about 8" x 10" x 18" high
Relays, BMS, disconnect switches and 1-0ff-2 switch under a lid in the top.
Sides would have some vents for air flow.
Each stack accessible from a door in the front perhaps with a slide out tray?
The box would have two handles to take it home during the winter.
3x16.75 lbs=50.25 lbs
The box could fit on the cabin sole under the folded up table, attached to the head bulkhead.
Wires could run along the top of the keel water tank and up to the box.

Now it looks like a box 18" high would interfere with sliding out the berth.
Will need to find a better location.
