To measure the open circuit voltage of an individual cell in the parallel combination, connect the DMM directly across the cell as shown in Figure 2. Figure 2: Measuring OCV of a single cell connected in a parallel configuration. The considerations for this measurement are similar to that of just a single cell.

This is especially useful for judging the cell balancing routines during charging and discharging that prevent cell stress and validating monitoring in the battery management systems.
This testing can be a bottleneck in the manufacturing process, so test solutions that reduce time or increase test density are highly desirable. One of the most useful measurements for a battery cell or pack is the open circuit voltage (OCV), but the considerations that must be made at the module or pack level differ from the cell level.
