1. A switched multi-cell battery system for an electronic device, the switched multi-cell battery system comprising:
an input voltage node;
an output voltage node;
a ground node;
a plurality of rechargeable battery cells comprising at least a first rechargeable battery cell with a positive terminal and a negative terminal and a second rechargeable battery cell with a positive terminal and a negative terminal; and
a plurality of power control switches comprising at least:
a first power control switch having a gate terminal, a first channel terminal coupled to the input voltage node, and a second channel terminal coupled to the positive terminal of the first rechargeable battery cell;
a second power control switch having a gate terminal, a first channel terminal coupled to the second channel terminal of the first power control switch, and a second channel terminal coupled to the output voltage node;
a third power control switch having a gate terminal, a first channel terminal coupled to the second channel terminal of the second power control switch, and a second channel terminal;
a fourth power control switch having a gate terminal, a first channel terminal coupled to the second channel terminal of the third power control switch, and a second channel terminal coupled to the ground node;
a fifth power control switch having a gate terminal, a first channel terminal coupled to the input voltage node, and a second channel terminal coupled to the positive terminal of the second rechargeable battery cell;
a sixth power control switch having a gate terminal, a first channel terminal coupled to the second channel terminal of the fifth power control switch, and a second channel terminal coupled to the output voltage node;
a seventh power control switch having a gate terminal, a first channel terminal coupled to the second channel terminal of the sixth power control switch, and a second channel terminal; and
an eighth power control switch having a gate terminal, a first channel terminal coupled to the second channel terminal of the seventh power control switch, and a second channel terminal coupled to the ground node.
