A battery pack and transport coupler for enabling the battery pack to reduce the pack power capacity. The battery pack include a plurality of strings of battery cells and a switching network for coupling and decoupling the strings of battery cells from each other. When the plurality of strings of battery cells are coupled together in a default configuration the transport coupler includes a decoupler for decoupling the strings of battery cells and when the plurality of strings of battery cells are not coupled together in a default configuration the transport coupler includes a coupler for coupling the strings of battery cells for operation with an electronic device such as a power tool.

1. A removable, secondary battery pack for providing electrical power to an electrical device, the battery pack comprising: a primary housing configured with a mechanical interface to mechanically couple the battery pack to each of a plurality of electrical devices within a system of electrical devices, wherein each of the plurality of electrical devices within the system of electrical devices includes a housing configured with a mechanical interface to mechanically couple the electrical device with the battery pack;sets of electrically connected battery cells housed within the primary housing;a switching network housed within the primary housing having a first state in which the sets of battery cells are electrically connected to each other and a second state in which the sets of battery cells are electrically disconnected from each other; andwherein, the battery pack being decoupled from the electrical device, a mechanical coupler that causes the switching network to convert between the first state and the second state. 2. A battery pack, as recited in claim 1, wherein the coupler maintains the switching network in the particular state during transportation of the battery pack. 3. A battery pack, as recited in claim 1, wherein the coupler includes a cap and a converter element, wherein the cap engages the converter element and the converter element connects contacts of the switching network. 4. A battery pack, as recited in claim 3, wherein the cap couples to an exterior surface of the primary housing. 5. A battery pack, as recited in claim 1, wherein the coupler includes a screw. 6. A battery pack, as recited in claim 1, wherein the coupler includes a tab. 7. A battery pack, as recited in claim 1, wherein the coupler includes a jumper. 8. A battery pack, as recited in claim 1, wherein the coupler includes an insulator. 9. A battery pack, as recited in claim 1, wherein each set of battery cells includes a positive and a negative terminal and the switching network comprises at least one of the positive terminals and the negative terminals of the sets of battery cells and a corresponding set of contacts to connect the at least one of the positive and negative terminals of the sets of battery cells. 10. A removable, secondary battery pack for providing electrical power to an electrical device, the battery pack comprising: a housing configured to mechanically mate with an electrical device;a plurality of sets of battery cells housed within the housing;a switching network housed within the housing and configured to electrically connect the sets of battery cells to each other and electrically disconnect the sets of battery cells from each other; anda mechanical converter for operating the switching network to electrically connect the sets of battery cells to each other. 11. A battery pack, as recited in claim 10, wherein the converter operates the switching networks. 12. A battery pack, as recited in claim 10, wherein the converter is a screw. 13. A battery pack, as recited in claim 10, wherein the converter is a pull tab. 14. A battery pack, as recited in claim 10, wherein the converter is a coupling device for electrically connecting the sets of battery cells to each other. 15. A battery pack, as recited in claim 10, wherein the sets of battery cells are electrically disconnected from each other within the housing in a default configuration. 16. A battery pack, comprising: a housing,a plurality of sets of battery cells housed within the housing, each set of battery cells having a positive terminal and a negative terminal,a set of battery pack terminals extending from the housing,whereina first terminal of the set of battery pack terminals extends from the housing for mating with an electrical device and is electrically coupled to the positive terminal of a first set of battery cells,a second terminal of the set of battery pack terminals extends from the housing for mating with the electrical device and is electrically coupled to the positive terminal of a second set of battery cells,a third terminal of the set of battery pack terminals extends from the housing for mating with the electrical device and is electrically coupled to the negative terminal of the first set of battery cells anda fourth terminal of the set of battery pack terminals extends from the housing for mating with the electrical device and is electrically coupled to the negative terminal of the second set of battery cells such that the first set of battery cells is electrically isolated from the second set of battery cells.
