Methods and apparatuses are described for use in self-reconfigurable multi-cell batteries. The methods include during charging of a multi-cell battery that includes a plurality of battery cores and a plurality of switches, controlling the plurality of switches to connect the plurality of battery cores in a series configuration or in a parallel configuration based at least on one or more of a current capability of a battery charger and a voltage capability of the battery charger. The methods also include during discharging of the multi-cell battery, controlling the plurality of switches to connect the plurality of battery cores in the series configuration or in the parallel configuration based at least on one or more of a current requirement of a load and a voltage requirement of the load.
