Series & Parallel packs explained
SeriesConnecting cells in series affects the total voltage (V) delivered by the battery pack. Each Lithium-ion cell provides 3.7V, and for safety purposes, the maximum voltage allowed for QwikBuild™ battery packs using Lithium-ion cells is 14.8V - a maximum of four (4) cells in series. Contact Totex directly for custom packs providing more than 14.8V output.
Parallel
Connecting cells in parallel affects the total capacity (mAh) of a battery pack.
Simply divide the total capacity needed for the application by the nominal capacity
of the cell selected in Step 1 to determine the quantity of cells required for
each battery pack. For the QwikBuild™ program the maximum number of lithium-ion
cells that may be connected in parallel is four (4).Contact Totex directly for
custom packs using more than four cells in parallel.
Series/Parallel
This configuration
illustrates how cells are grouped in packs to provide various voltage outputs
and capacities. Up to four cells are clustered together in parallel to provide
a desired capacity - the multiple of a selected cell's nominal capacity measured
in mAh. These parallel clusters are then connected in series to increase voltage
output in increments of 3.7V (1 cluster = 3.7V; 4 clusters = 14.8). As parallel
clusters are added in series, only the voltage increases; overall battery pack
capacity is the same as the capacity of a single parallel cluster, regardless
of the number of clusters in the pack. Four clusters of four cells each are
the maximum from our QwikBuild™ program. Please call Totex directly for
other custom configurations.
