Choosing between series and parallel battery connections is crucial for optimizing your power system’s performance. Connecting batteries in series increases voltage, while connecting them in parallel increases capacity. Understanding these differences will help you determine the best configuration for your specific application.
What Are the Basics of Series and Parallel Connections?
In battery configurations:
Series Connection: Batteries are connected end-to-end, resulting in increased total voltage while maintaining the same capacity. For example, connecting two 12V batteries gives you 24V.
Vtotal=V1+V2
Parallel Connection: Batteries are connected with positive terminals together and negative terminals together, increasing total capacity while keeping voltage constant.
Ctotal=C1+C2

How Do Series Connections Affect Voltage and Capacity?
The choice between series or parallel configurations affects how your power system operates:
Voltage: In series, voltages add up, making it suitable for applications requiring higher voltage.
Capacity: In parallel, capacities add up, ideal for applications needing longer runtimes.
Can You Connect Batteries in Series and Parallel at the Same Time?
Yes, you can connect batteries both in series and parallel to achieve desired voltage and capacity levels. This is often seen in larger battery banks where:
Multiple groups of batteries are wired in series to increase voltage.
These groups are then connected in parallel to boost overall capacity.

What Are the Risks of Mixing Battery Types in Series-Parallel Configurations?
Mixing different types or capacities of batteries can lead to several risks:
Imbalance: Different charge/discharge rates can cause one battery to over-discharge or overcharge.
Reduced Efficiency: The overall system may perform poorly if one battery type dominates.
Safety Hazards: Mismatched batteries can lead to overheating or failure.
