This paper presents the algorithms. hardware overview and testing results for controlling discharge currents from mixed battery modules placed in a parallel configuration. Battery modules with different open-circuit voltage (OCV). internal impedance or even state of charge (SOC) between modules are usually used to form a battery pack. https://www.roneverhart.com/1915-Old-Taylor-Bourbon-Bottled-1933-Prohibition-Bottling-Quart-low-fill/
