Industry Factors in Series Strings
These repeating patterns are important whether the pack is a modular or cell to pack design. As we connect the cells together in parallel and then in series the break points are in the series connections. If we want a 350V battery pack and have 3.6V cells the closest is 97 cells. 97 is a prime and hence only divisible by itself and 1.

6 Frequently Asked Questions about “Change the battery pack from 20 strings to 24 strings”
Can a lithium ion battery pack have multiple strings?
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:
Should a battery pack be paralleled?
Paralleling strings together greatly increases the complexity of managing the battery pack and should be avoided unless there is a specific reason to use this configuration. In this setup, each string must essentially be treated as its own battery pack for a variety of reasons. In a below example, 2 strings of 8 cells each are placed in parallel.
How many strings should a lithium battery have?
Therefore, the lithium battery must also be about 58v, so it must be 14 strings to 58.8v, 14 times 4.2, and the iron-lithium full charge is about 3.4v, it must be four strings of 12v, 48v must be 16 strings, and so on, 60v There must be 20 strings in parallel with the same model and the same capacity.
How do Battery strings work in a parallel set?
Note: Energy from the battery is always sourced from the system of the lowest impedance. This is why the strongest battery string provides the power first and when it becomes depleted less than another string, that one then takes over. In a parallel set, they work in unison to balance each other out.
How many cells are in a single string?
In the above example, 8 cells are configured in a single string. This is an “8S1P” configuration. The “8S” indicates that there are 8 cells in series and the “1P” indicates that there are no paralleled cells. If each cell is 10 amp hours and 3.3 volts, the battery pack above would be 10 amp hours and 26.4 volts (3.3 volts x 8 cells).
How many volts are in a battery pack?
If each cell is 10 amp hours and 3.3 volts, the battery pack above would be 10 amp hours and 26.4 volts (3.3 volts x 8 cells). For this setup, a BMS capable of monitoring 8 cells in series is necessary. Lithium cells can almost always be paralleled directly together to essentially create a larger cell.
