A framed lithium battery cell group includes a first frame member (20) and a second frame member (30). The frame members are locked together, clamping the lithium battery cell pack (10) on the seal edge surfaces (13, 16), thereby providing structural rigidity and protection from damage due to handling and vibration. Each of the frame members (20, 30) has multiple pins (25) and sockets (26) on the side opposite the clamping surface (33) to facilitate aligning and stacking multiple lithium battery cell pack and frame assemblies to form a lithium battery cell group (50). Each of the frame members (20, 30) include a buss bar capture feature (22, 32) having a bus bar (40) inserted therein for electrically connecting all of the terminals for a given lithium battery pack group to the buss bar (40).
