PARALLEL-COUPLED CELLS

"Individual electrochemical cells can be combined in assemblies by parallel or series coupling (or a combination of the two). In case of ""parallel"" coupling, the positive electrode of every cell is connected together and the negative electrode of every cell is connected together, resulting in two external terminals. The voltage of every cell must be identical in parallel coupled assemblies. The overall current passing through the assembly is the sum of the individual cell currents, while the assembly voltage is identical to the individual cell voltage. Parallel coupling is often used in batteries. Cell lines and stacks can also be parallel coupled. Contrast with series coupling. "
