First Claim
1. A configurable battery comprising:
- a plurality of battery cells;
means for switchably connecting said plurality of battery cells in series according to one switching condition and in parallel according to another switching condition;
a microprocessor powered by at least one of said battery cells, responsive to electrical signals for causing said one switching condition and for causing said another switching condition;
a unitary housing inside of which said battery cells, said means for switchably connecting, and said control means are all disposed; and
means for communicating electrical signals representing a desired voltage from an exterior of said housing to said microprocessor.

Abstract
A battery and circuitry for monitoring state of charge of the battery are housed in a single housing. A display may be provided for displaying an indication of the state of charge, and a communication circuit may be provided for communicating electrical signals representing the state of charge to the exterior of the housing. Preferably, the battery module additionally includes a switch device for connecting the battery to terminals external to the housing and control circuitry responsive to the monitoring circuitry for causing the battery to be connected to and disconnected from the terminals. The control circuitry operates in accordance with thresholds to prevent deep discharge and overcharge.
