agm's a re a terrible idea for electric propulsion, 300 cycles? that's one year
i Mix 1045ah of AGM at 12v and 2kw of lithium also at 12v on a sailboat because I can't risk a BMS failure killing all communications, navigation, nav lights etc, and I have that amount of storage because I like to run the air conditioning in silence, I use the generator every few days to supplement the 2kw of solar.
I'd recommend 32prismatic Lifepo4 in series with a 32S BMS rated for the amperage of both motors, but truthfully you should have 2 p6v banks incase one fails.
I beleieve one of the ev's maybe a leaf has 96v batteries that could be adapted. Jehu Garcia probably has something that would work, but you have more to consider, 12v batteries charge at around 14v 48v batteries charge at around 52v so 96v will charge in the 104v range, most MPPT chrgers need 20-30% higher voltage so you'll need enough solar panels in series to give say 150v.
I don't know who makes MPPT chargers in that range.
the gas outboards are starting to look better to me.
