What is called when two or more batteries are connected to provide more current capacity?

When two or more batteries are connected in such a way that their voltage remains the same while the current capacity increases, this configuration is referred to as a parallel connection. In a parallel setup, each battery combines its capacity with the others, allowing them to supply more total current to a load, while the voltage remains constant at the level of a single battery. This is particularly useful in applications where more power is needed for longer durations, as it enhances the overall performance without altering the supply voltage.

In contrast, other configurations, such as series connections, would increase the voltage rather than the current capacity. Grouped connection and linked connection are not standard terms used in battery configuration discussions and do not accurately describe the method of combining batteries to increase current capacity. Thus, understanding the characteristics and advantages of a parallel connection is essential for effectively managing battery-powered systems.
