Beschreibung
Zusammenfassung:	The disclosed technology relates to balanced battery packs having battery cells of different capacities with higher capacity battery cells having a reduced impedance compared to lower capacity battery cells in the battery pack. The battery pack includes at least a first and second battery cell connected in parallel, with the second battery cell having a higher capacity than a capacity of the first battery cell. Tabs extending from electrodes of the second battery cell are disposed near a center of the electrodes to reduce an impedance of the second battery cell.
