The package of claim 1, further comprising: caps positioned on ends of the tubular wall. 16. The package of claim 1, wherein the first conductive portion, the second conductive portion and the insulative partition are positioned serially along a height of the wall. 17. The package of claim 1, wherein the insulative partition does not extend into an internal volume of the case by more than 100% of a thickness of the conductive case portion. 18. The package of claim 1 wherein the insulative partition and the conductive portions each include an interior that together define a portion of an interior of a chamber. 19. The package of claim 1, wherein the one or more positive electrode and the one or more negative electrodes are arranged in a jellyroll. 20. The package of claim 19, wherein one or more positive tabs provide electrical communication between the first conductive portion and the one or more positive electrodes, and one or more negative tabs provide electrical communication between the second conductive portion and the one or more negative electrodes, the one or more positive tabs and the one or more second tabs extending from the jellyroll in opposite directions. 21. The package of claim 20, wherein a positive tab is partially positioned between the first conductive portion and a first end cap and a negative tabs is partially positioned between the second conductive portion and a second end cap. 22. The package of claim 1, wherein one or more positive tabs provide electrical communication between the first conductive portion and the one or more positive electrodes, and one or more negative tabs provide electrical communication between the second conductive portion and the one or more negative electrodes. 23. The package of claim 22, wherein the one or more positive tabs are connected to the first conductive portion. 24. The package of claim 23, wherein a positive tab is partially positioned between the first conductive portion and a first end cap. 25. The package of claim 24, wherein a positive tab is partially positioned between the first conductive portion and a first end cap, the first end cap fitting into a hole in the first conductive portion. 26. The package of claim 24, wherein a positive tab is partially positioned between the first conductive portion and an end cap, and a negative tab partially positioned between the second conductive portion and a second end cap.
