Re: "Apple is examining a chemistry for the car battery called LFP, or lithium iron phosphate, for its car", that will bring the cost down for all of us

This will not likely have a trickle down effect for marine batteries anytime soon.  The key differentiator for Apple is the "monocell" cell design, not the LFP chemistry.  It's their way of trying to make up for the lower energy density of the LFP chemistry compared to other Lithium Ion chemistries like the NCA chemistry (lithium-nickel-cobalt-aluminum) that Tesla mainly uses.  Tesla batteries are made from older, proven cylindrical cell design as well as a different NCA chemistry.  Scott, your Victron batteries actually use prismatic LFP cells, not cylindrical cells: 

Most other drop-in batteries like Battleborn do use cylindrical LFP cells to make their batteries.
