A battery pack (e.g., a battery pack for marine environments) can include a lower enclosure having an upper wall and defining a cavity, a plurality of battery cells positioned within the cavity, a radiator assembly positioned above the upper wall of the lower enclosure, a vent in the upper wall of the cavity, and/or a valve configured to selectively facilitate fluid communication between the cavity and the radiator assembly via the vent. In some embodiments, the valve is configured to open in response to increased pressure in the cavity resulting from a thermal runaway event. In some embodiments, the radiator is configured to create a tortuous path and collect flammable particulates from the thermal runaway event.

Batteries for electric marine propulsion systems, and associated systems and methods

A battery fleet charging system for charging two or more battery packs simultaneously, at independently controlled charge rates. The present invention can intelligently distribute the available charge power among multiple batteries, either symmetrically or asymmetrically, as specified by a controller that specifies and regulates the charge voltage.

Battery fleet charging system

Battery pack

A watertight, transom mounted, electric marine sterndrive propulsion drive unit mounted to an external surface of the transom of a marine vessel comprising an integrated electric motor with an output shaft, an intermediate drive shaft mechanically coupled to the electric motor output shaft, one or more propeller shafts mechanically coupled to the drive shaft, and one or more propellers mechanically coupled to the one or more propeller shafts.
