a voltage threshold detecting circuit with an input channel;
a first network that selectively couples the first battery cell to the input channel;
a second network that selectively couples the second battery cell to the input channel; and
a voltage applied to the input channel when the first network and second network are coupled to the input channel being greater than a voltage applied to the input channel when the first network is coupled to the input channel.
