1. An electrical module configured to be coupled to a tray of a battery distribution assembly, the electrical module comprising:a housing disposed along an outer surface of the tray, the housing including a base and a cap, the cap engaging a top side of the base to define a cavity between the cap and the base;
at least one electrical circuit device disposed within the cavity of the housing; and
multiple terminals electrically connected to the at least one electrical circuit device within the housing, the terminals projecting from the housing and extending through corresponding apertures in the tray to electrically connect to one or more electrical conductors disposed along an inner surface of the tray,
wherein the cap is non-removably bonded to the base such that the at least one electrical circuit device is permanently contained within the cavity.
