1. A method comprising:
sensing condition of power cells in a configured multiple power cell pack via a pack management unit;
based in part on the sensing, identifying a number of the power cells as a number of target cells via the pack management unit;
disabling sensing condition of the number of target cells via the pack management unit; and
reconfiguring the multiple power cell pack via the pack management unit to provide a reconfigured multiple power cell pack that provides power without the number of target cells.
 
19. A pack management unit comprising:
a processor;
memory accessible to the processor;
processor-executable instructions stored in the memory and executable to instruct the pack management unit to:
sense condition of power cells in a configured multiple power cell pack;
based in part on the sensed condition of the power cells, identify a number of the power cells as a number of target cells;
disable the sense condition of the number of target cells; and
reconfigure the multiple power cell pack to provide a reconfigured multiple power cell pack that provides power without the number of target cells.
 
20. One or more computer-readable storage media comprising processor-executable instructions executable to instruct a pack management unit to:
sense condition of power cells in a configured multiple power cell pack;
based in part on the sensed condition of the power cells, identify a number of the power cells as a number of target cells;
disable the sense condition of the number of target cells; and
reconfigure the multiple power cell pack to provide a reconfigured multiple power cell pack that provides power without the number of target cells.
