1. A multi-core lithium ion battery, comprising:
an enclosure including a base, and a plurality of sidewalls that define an internal volume;
a support member positioned within the enclosure, wherein the support member defines a plurality of cavities;
a cover relative to the enclosure in substantial alignment with the base so as to enclose the internal volume of the enclosure;
a plurality of jelly roll assemblies disposed within a corresponding one of the plurality of cavities; and
at least one positive bus bar defining a first plane and electrically connected to the plurality of jelly roll assemblies, the at least one positive bus bar including a positive connective structure mounted with respect to a connective region defined by the at least one positive bus bar;
at least one negative bus bar defining a second plane and electrically connected to the plurality of jelly roll assemblies, the at least one negative bus bar including a negative connective structure mounted with respect to a connective region defined by the at least one negative bus bar;
wherein the first plane and the second plane are in parallel spaced alignment; and
wherein the positive connective structure and the negative connective structure are configured and dimensioned to mount with respect to the cover in a common plane.
