1. An energy supplying component (100) comprising:
(a) a plurality of power sources (161, 171, 181, 191), wherein each power source of the plurality of power sources is configured to output a defined energy level, the plurality of power sources comprising a first beta-voltaic power source (191) and at least one additional beta-voltaic power source (161, 171, 181);
(b) a plurality of switches (163, 165, 167, 173, 175, 177, 183, 185, 187, 193, 195, 197) configured to reversibly combine two or more power sources of the plurality of power sources for enabling the energy supplying component to supply energy at one or both of a needed voltage or a needed current, the plurality of switches comprising:
(i) a first switch (193),
(ii) a second switch (195), and
(iii) a third switch (197); and
(c) a plurality of ports (162, 164, 166, 168, 172, 174, 176, 178, 182, 184, 186, 188, 192, 194, 196, 198) the plurality of ports comprising:
(i) a first port (192), the second switch being interposed between the first power source and the first port,
(ii) a second port (194), the first switch being interposed between the first power source and the second port,
(iii) a third port (196), the third port being configured to couple the first power source with ground, and
(iv) a fourth port (198), the second and third switches being interposed between the first power source and the fourth port,
wherein the first switch, the second switch, and the third switch are operable to selectively complete a circuit between the first port to the second port, the circuit including one or both of the first power source or the additional power source of the plurality of power sources, and
the second switch being operable to selectively couple the first power source with the second power source in series, the first and third switches being operable to selectively couple the first power source with the additional power source in parallel.
