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:

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.
