What are parallel and Series circuits in LiFePO4 batteries?

Before addressing the necessary precautions, it's essential to understand the basics of parallel and series circuits, including their definitions and unique characteristics. Series connection of LiFePO4 batteries involves linking multiple cells in a sequence to boost the total voltage output.

How does connecting LiFePO4 batteries in parallel affect capacity?

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. For instance, if four 12V batteries are connected in series, the output voltage of the battery pack will be 48V.

How does a series connection of LiFePO4 batteries affect voltage?

In a series connection, the voltage output of the battery pack increases. Both series and parallel connections of LiFePO4 batteries can increase the overall performance of the battery pack.
