Recommended cell types

[Argosy]

Was about to pull trigger on the A123 LifePo4 from BigBattery to build a 24V 600ah bank in a boat.
Then theres a group buy of 280ah aluminum encased cells.

Want the safest batteries/etc --- wondering what is recommended as there are many types/price points.

A123 - 24v 100ah $650ea - $270/kwh
280ah Group Buy (aluminum cased prismatic) - 24V 280ah $800 - $119/kwh
CALB Plastic case cells 24V 200ah - $216/kwh
Fortune 24V 100ah - $400/kwh

What others are recommended?
