Battery packs are presented having structural members for improving thermal management of battery cells therein. In some embodiments, the battery packs include a first end-member positioned opposite a second end-member and parallel thereto. The battery packs also include a first side beam positioned opposite a second side beam and parallel thereto. The first side beam and the second side beam extend longitudinally between the first end-member and the second end-member. A longitudinal member is disposed between the first side beam and the second side beam and defines a plurality of longitudinal rows. The battery packs may additionally include a lateral member disposed between first end-member and the second end-member to partition the plurality of longitudinal rows into an array of battery cell compartments. A battery cell is disposed within at least one battery cell compartment.
