When a battery bank is attached positive to positive and negative to negative, what kind of circuit does it make?

Series
Parallel
Open
Closed

The correct answer is: Parallel

When a battery bank is connected with positive terminals to positive and negative terminals to negative, it creates a parallel circuit. In a parallel configuration, each battery serves as a separate branch, allowing each battery to maintain its own voltage while increasing the overall capacity (amp-hour rating) of the system. This means that the voltage of the bank remains the same as that of an individual battery, while the total capacity increases, which is essential for applications requiring higher power or longer run times. In a parallel connection, if one battery fails, the others can still operate independently, which enhances reliability. This configuration is commonly used in RV applications where maintaining voltage stability while providing sufficient power for various devices is crucial. Parallel circuits are characterized by multiple paths for current flow, which can both improve resilience and enhance the system's overall energy capacity.
