1. A battery enclosure for a vehicle chassis comprising:
a base member having an upper and lower surface, the base member having a plurality of raised surface features on the upper surface outlining individual cells, each of the plurality of raised surface features having a first height extending normally from the lower surface, each cell configured to receive at least one battery;
a cover member having an upper and lower surface, the cover member having a plurality of depending surface features on the lower surface outlining individual cells, the surface features of the cover member aligned with the surface features of the base member, and the cover member having at least one channel formed in the upper surface thereof, aligned with and extending along a length of the depending surface feature disposed on the bottom surface, wherein at least one depending surface feature of the cover member extends a distance greater than at least one raised surface feature of the base member;
wherein the cover member and the base member are configured to form a seal around at least one individual cell;
a lattice support structure, the lattice support structure including a plurality of support members extending axially and a plurality of support members extending transversely,
wherein the lattice support structure is configured to be at least partially disposed within the channel of the cover member, with a transverse support member disposed between adjacent cells of the base member;
wherein the plurality of support members are formed from hollow beams; and
wherein at least one of the base member, cover member and lattice support structure are configured to form a portion of the vehicle chassis.
