Battery Configuration Calculator
Definition: This calculator determines the total voltage, capacity, and energy of a battery pack based on individual cell specifications and series/parallel configuration.
For instance, if four 12V batteries are connected in series, the output voltage of the battery pack will be 48V. In contrast, parallel connection of LiFePO4 batteries increases the overall capacity of the battery pack, but the voltage output remains the same as that of an individual cell or battery.
The nominal voltage of the final set of cells is the number of cells in series times the nominal voltage of a single cell. If we look at the battery packs out there we can see that they cover the range of nominal voltages from 3.2V to 820V in the graph (plotted from the Battery Pack Database).
For instance, LiTime allows for a maximum of four 12V lithium batteries to be connected in series, resulting in a 48-volt system. It's always important to consult the battery manufacturer to ensure that you stay within their recommended limits for series connections.
More efficient energy storage: In a series-connected battery pack, each cell shares the load equally, ensuring that each cell is charged and discharged at the same rate. As a result, the overall energy storage is more efficient. Series connection is ideal for applications that require high voltage, such as RV and solar power systems.
