Thanks for the links! When I first began my research, I thought the 30A Orion would be the solution. Since then, with all the videos that I have watched, and what the lithium batteries are capable, it became clear that the 50A Orion was a much better solution. That is what is on my shopping list along with 4 gauge wire, etc. Your suggestion is yet another confirmation that the 50A is the right solution. Now if I can get past the worry of pulling all these wires properly and getting through the hull, I will pull the trigger on my shopping list. I can always find something to worry about!
