— Battery Series/Parallel Configuration

Pack voltage and capacity for cells arranged Ns in series by Np in parallel: pack voltage = Ns·Vcell (capacity unchanged by series stacking), pack capacity = Np·Ahcell (voltage unchanged by parallel stacking). Assumes matched, healthy cells.

Ns in series (voltage adds) Np in parallel (capacity adds)
Series strings raise voltage; parallel strings raise capacity.
