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).
Why are parallel lithium strings important?
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.
