1. A marine battery pack comprising:
an enclosure defining a cavity;
a plurality of cell modules within the cavity, each comprising a plurality of battery cells;
at least one sensor configured to sense at least one of a temperature, a pressure, a presence of water, and a gas content within the cavity;
a pump configured to intake water from a surrounding body of water outside the enclosure and pump the water throughout the cavity from an inlet port in the enclosure to an outlet port in the enclosure;
at least one power switch configured to selectively connect each of the plurality of cell modules to the pump so as to power the pump:
a controller configured to:
detect an event warranting decommission of the battery pack based on the temperature, the pressure, the presence of water, and/or the gas content within the cavity;
control the at least one power switch to connect the plurality of cell modules to the pump to power the pump; and
in response to detecting the event warranting decommission of the battery pack, automatically operate the pump to intake water from the surrounding body of water outside the enclosure and pump the water throughout the cavity from the inlet port in the enclosure to the outlet port in the enclosure so as to cool the plurality of battery cells.
