Zusammenfassung:	A rechargeable battery pack system includes a charging base and rechargeable battery packs. The charging base includes an electrical connector for receiving electrical power and a set of electrical contacts. The rechargeable battery packs each include a rechargeable battery, electrical circuitry, and an inductive coil for wirelessly transmitting power to an electronic device. The rechargeable battery packs each include a first set of electrical contacts to electrically contact the charging base for receiving electrical power from the charging base when the battery pack is stacked on top. The rechargeable battery packs further include a second set of electrical contacts for providing electrical power to another rechargeable battery pack when the other rechargeable battery pack is stacked on top. The second set of electrical contacts is activated for providing the electrical power to the other rechargeable battery pack only after receiving a proper identity code from the other rechargeable battery.
