Series Strings
Cells combined in series strings will achieve higher operating voltages by connecting the positive terminal of
one cell to the negative terminal of the next cell. Connect strings of series AMP20 cells using their current
collection tabs in a manner similar to that illustrated in Figure 5.
Figure 5 – Example of AMP20 cells connected in series
Two cells in series: 2 x 3.3V = 6.6V (nominal)
Four cells in series: 4 x 3.3V = 13.2V (nominal)
Connect strings of series cylindrical cells using their current
collection tabs in a manner similar to that illustrated in the
figure to the right.
A single cell’s normal operating range is between 2V and 3.6V
(See Appendix A for complete specifications). A pack with n multiple cells in series would then have an operating
voltage range of n x 2.0 to n x 3.6 (where n is the number of cells in series). For example, a two series cell
combination would have a voltage range between 4 and 7.2V, with a nominal voltage of 6.6V.
