A battery bank needs to store at least 2300 Wh of energy at 56 V outside where the ambient air temperature is 0° C. You have access to lead acid batteries that have a nominal capacity of 18 Ah at 10 V at 25° C. What is the minimum number of batteries required to meet this charging requirement? Draw a schematic of the battery configuration.
