Battery/Cell Arrangement

Cell arrangement (also battery arrangement or battery configuration) refers to how the cells are grouped to provide power with sufficient current and voltage output for the application.

• Series arrangements raise pack voltage
• Parallel arrangements increase pack current capacity, as well as balance cells if they are cross-connected.
