1. A power storage system for a marine vehicle, comprising:
a plurality of marine battery systems configured to provide energy to a marine vehicle load and arranged in either one of a parallel configuration and a series configuration with the marine vehicle load, each marine battery system comprising
a battery;
a three-position contactor configured to operate the marine battery system in one of a connected state, a disconnected state, or a bypass state;
a controller coupled to each of the plurality of marine battery systems, wherein the controller is configured to:
retrieve a preferred fault action for the plurality of marine battery systems; and
in response to detection of a fault condition in the marine vehicle, control at least one three-position contactor of the plurality of marine battery systems according to the preferred fault action; and
wherein the preferred fault action is based on arrangement of the plurality of marine battery systems and comprises operating the marine battery system in the disconnected state or operating the marine battery system in the bypass state.
