One embodiment includes a housing, a first battery cell having a first cell thermal capacitance, the first cell fixedly disposed in the housing, a second battery cell having a second cell thermal capacitance, the second cell fixedly disposed in the housing a minimum air gap away from the first cell, the minimum air gap having an air gap thermal resistance and a heat conductor disposed adjacent each of the cells, with the heat conductor having a heat conductor heat capacitance. A combination of the first cell thermal capacitance, the second cell thermal capacitance, the heat conductor thermal capacitance and the air gap is sufficient to restrict heat flow from the first cell to the second cell during a thermal runaway event of the first cell, the heat flow restricted such that the second cell temperature remains less than a temperature sufficient to cause thermal runaway in the second cell.
