Claim 15:
16. The switched multi-cell battery system of claim 12, further comprising a battery management system comprising:
a first operational amplifier configured to reference the positive terminal of the second rechargeable battery cell to the ground node to produce a first voltage potential Va;
a second operational amplifier configured to reference the positive terminal of the first rechargeable battery cell to the ground node to produce a second voltage potential Vb;
a multiplexer configured to select between the first voltage potential Va produced by the first operating amplifier and the second voltage potential Vb produced by the second operational amplifier to produce a first multiplexer output and a second multiplexer output; and
a third operational amplifier configured to reference the first multiplexer output to the second multiplexer output to produce a third voltage potential Vc.
