Arrangements for inhibiting intrusion into battery pack electrical components

A water-resistant battery pack comprising:

• a housing;
• a terminal operable to connect to an electrical device for power transfer;
• a battery cell supported by the housing and including a cell header, the battery cell having a rated voltage of 3.6 V, the battery cell having a capacity between 2 Ah and 5 Ah;
• a water-resistant ring providing a water-resistant seal at an interface of the cell header;
• a conductive element electrically connecting the battery cell to the terminal;
• and
• an insulating sheet provided between the conductive element and the housing.

A water-resistance battery pack comprising:

• an outer housing;
• a controller operable to control an operation of the battery pack;
• a terminal operable to connect to an electrical device for power transfer;
• a cell module within the outer housing, the cell module including:
• a module housing,
• at least one battery cell supported by the module housing and including a cell header,
• a water-resistant ring provided at the cell header,
• a conductive element electrically connecting the at least one battery cell to at least one of the controller and the terminal, and
• a protective film applied to at least a portion of the conductive element;
• and
• an insulating sheet provided between the module housing and the outer housing.
