A battery module cell cover is provided including a number of features configured to orient, capture, and isolate battery cell interconnections relative to battery cell locations in an array of battery cells. Isolation features may block a negative terminal battery cell interconnect from moving out of an orientation receptacle aligned with a negative terminal of a battery cell and into contact with a positive terminal of the battery cell, or vice versa. The battery module cell cover can include a number of structural connection features protruding from a planar surface into a battery cell containment cavity, between battery cell locations, that provide a number of surfaces for curing to structural adhesive of the battery module. These structural connection features, in conjunction with the structural adhesive, can assist in forming a unified strengthened structure of the battery module.
