A protection circuit module (PCM) in each battery pack is N configured to determine a state of each of the connections among the sub-assemblies (i.e., whether or not properly assembled to provide CN electrical continuity through the connector) so that power from the battery packs is switched on to the power bus only when electrical Il ---- continuity is verified at each of the connectors. In the event that any connection is faulty, for example due to a misalignment of a I r ---- connector during assembly that prevents electrical continuity to be established through a connector, neither PCM will switch power Il cz on to the power bus.
