Battery Assembly for Aerospace Vehicles

Disclosed are methods and systems for aerospace vehicle batteries. For instance, a battery assembly may include a first and second battery assembly terminals; a plurality of battery cells, the plurality of battery cells being arranged in groups, each group of battery cells having a stacked arrangement of n by m battery cells orientated in a same direction, n being at least two and m being at least two; a first subset of the groups form a first linear arrangement arranged end-to-end in a first direction; and a second subset of the groups form a second linear arrangement arranged end-to-end in a second direction; a plurality of group connectors, each being configured to connect two respective battery cell groups; and a linear arrangement connector configured to connect the first linear arrangement to the second linear arrangement.
