I would only consider an integrated Li-ion system with a dedicated battery management system made by a name brand manufacturer of marine electrical equipment. Mastervolt is one of these.

But they ain't cheap. Almost $7,000 for 320 amp hours worth of ain't cheap!!

See Mastervolt MLI 12V - 320 AH Lithium Ion Battery

You can do the same for about $400 with lead acid batteries.
