Whenever possible, using a single string of lithium cells is usually the preferred configuration for a lithium ion battery pack as it is the lowest cost and simplest. However, sometimes it may be necessary to use multiple strings of cells. Here are a few reasons that parallel strings may be necessary:
If there are only two batteries in the series string (Figure 1), we would then take a cable from the open POS. (+) terminal of the first battery and a cable from the open NEG. (-) of the second (last) battery in the string to the load and charger/power source.
If there are only two batteries in the parallel string, we would then take a cable from the POS. (+) terminal of Battery 1 to the charger. We would use the POS. (+) terminal of Battery 2 for connection to the loads.
Since lithium cells must be managed on a cell level, parallel lithium strings dramatically increase the complexity and cost of the battery management and introduce many additional points of failure and failure modes not found with a single string.

A 24V LiFePO4 battery is commonly configured using eight cells&32;connected in series (8S). This configuration allows the battery to achieve a nominal voltage of 25.6 volts (8 cells x 3.2 volts per cell).
The maximum is at around 3 (or 4) paralleled strings. The reason for this is that with a large battery bank like thi,it becomes tricky to create a balanced battery bank. In a large series/parallel battery bank,an
