Lithium battery packs can be used in series to increase voltage while keeping the capacity the same. Here are some key points:Voltage Addition: When lithium batteries are connected in series, their voltages add up. For example, two 3.7V cells in series will provide 7.4V2.Capacity: The overall capacity (Ah) remains the same as that of a single cell in the series1.Balancing: It is crucial to balance the batteries in series by charging them individually to the same voltage to prevent issues3.Internal Resistance: Connecting batteries in series increases the internal resistance, which can affect performance1.Configuration: A common notation for battery packs is XsYp, where X is the number of cells in series and Y is the number of cells in parallel4.
