Abstract:
1. A battery pack comprising: a rechargeable battery; an input member for connecting the battery pack to an external power source; an output member for connecting the battery pack to an external device for power supply to the external device; a micro-controller for sensing at least one characteristic of an electrical signal supplied from the external power source connected to the input member, and for controlling an output signal at the output member based on the sensed characteristics of the electrical signal supplied from the external power source connected to the input member; and wherein: in a programming mode, the micro-controller is capable of setting characteristics of the output signal to be substantially the same as the sensed characteristics of the electrical signal supplied from the external power source: and the characteristics of the output signal and the sensed characteristics of the electrical signal supplied from the external power source each comprise at least one of a voltage limit and a current limit.
