Claim 6:
7. A method, comprising:
selectively varying, by controller of a battery device, output polarity from a multi-cell battery cluster, wherein the controller is connected to the multi-cell battery cluster and comprises at least two direct current (DC) output poles, at least two alternating current (AC) output poles, and a plurality of switches configurable to control respective voltage outputs of battery cells of the multi-cell battery cluster;
controlling, by the controller, using the plurality of switches, respective battery cells of the multi-cell battery cluster to selectively separately provide negative output voltage, positive output voltage, and no output voltage; and
concurrently providing at least one DC voltage output by the at least two direct current (DC) output poles, and at least one AC voltage output by the at least two alternating current (AC) output poles based on the controlling.
