A method for power management of a multi-cell battery includes identifying a desired power value and voltage value, determining a battery voltage value and a battery current value for a battery, determining a number of battery banks from a plurality of battery banks to use for the battery, where each battery bank includes one or more battery cells (or battery modules), checking availability of each of the one or more battery cells (or battery modules), selecting one or more battery banks from the plurality of battery banks, where the selection of a battery bank is based on the availability of the battery cells (or battery modules) included in the battery pack, and a quantity of the selected battery banks is equal to the determined number of battery banks, and connecting the available battery cells (or battery modules) in the selected one or more battery banks to form the battery.
