Pro tip, don't use amp hours for batteries. It's only half the information and is a holdover of when lead acid 12v systems were the ONLY choice. Use watt hours or kilowatt hours instead. This will take into account if your pack is 12, 24, 48, or any other system design. This is especially important considering that bare lithium cells are 3.7 volts nominally.
Why not? They provide MUCH more capacity (not just in their nominal capacity but in their *useful* capacity vs lead acid), have a MUCH longer lifespan, are less expensive (when considering the more frequent replacement of lead acid), are lighter, and (in some ways) are safer (no hydrogen production, no acid spills).

Good point, very true. Appreciate the feedback and thanks for watching.
I most definitely wouldn't be using lithium batterys on a boat!
