A module for interconnecting electrical components such as batteries, fuel cells, capacitors, and resistors. The module has a body for retaining the electrical components, and terminal bulkheads capable of coupling with the body. The terminal bulkheads have cavities that define fluid reservoirs when the terminal bulkheads are coupled with the body, and gaskets that seal the fluid reservoirs. Electrical contacts of the terminal bulkheads contact the electrical components within the sealed fluid reservoir. The fluid reservoirs are filled with a fluid such that forces applied to the electrical components are dampened, and oxidation of electrical connections is mitigated through displacement of oxygen. The fluid can also be selected to neutralize chemicals that may leak from the electrical components. The electrical contacts can be interconnected with conductor buses such that the electrical components are connected in series, parallel, or a mixture of both.
