SERIES-COUPLED CELLS

"Individual electrochemical cells can be combined in assemblies by series or parallel coupling (or a combination of the two). In case of ""series"" coupling, the positive electrode of one cell is connected to the negative electrode of the next cell, and so on. The assembly has only two external terminals. The overall voltage of the assembly is the sum of the individual cell voltages, while the current passing through every cell (and the assembly) is the same. Series coupling can be used in a number of assemblies, such as battery, cell line, and stack. Contrast with parallel coupling. "
