Lithium iron phosphate (LiFePO4) battery packs can be connected in both parallel and series configurations to achieve desired voltage and capacity.Connecting in Series: This configuration increases the overall voltage while maintaining the same capacity. For example, connecting two 3.2V batteries in series results in a total voltage of 6.4V2.Connecting in Parallel: This configuration increases the overall capacity while keeping the voltage constant. For instance, connecting two 3.2V batteries in parallel maintains the voltage at 3.2V but doubles the capacity3.Combining Both: You can first connect multiple battery packs in parallel to increase capacity and then connect these parallel groups in series to achieve a higher voltage5.This method allows for flexibility in designing battery systems for various applications.
