Wiring batteries in both series and parallel configurations is possible and is so beneficial that be used in many power systems. To wire batteries in a series-parallel setup, first connect pairs of batteries in series by linking the positive terminal of one battery to the negative terminal of the next.
Let’s explore all about Batteries in Series vs Parallel configurations: When batteries are connected in series, the positive terminal of one battery is connected to the negative terminal of another battery. The voltage adds up while the capacity (ampere-hours) remains the same. Here’s a summary of the characteristics of batteries in series:
However, it is important to note that if one battery fails or becomes discharged faster than the others, it can affect the entire series. On the other hand, charging batteries in parallel offers increased capacity and longer runtime. This method allows for better balance between individual cells since they all share the load equally.
There's no limitation for connecting batteries in series or in parallel. However, remember to note that you can't exceed the limitation of the whole system. For example, you should not wire too many batteries in series so that the voltage exceeds the battery management system can control.
If uninterrupted operation is critical, connecting batteries in parallel provides redundancy and ensures continuous power supply even if one battery fails. To better understand the practical applications of series and parallel battery connections, let’s explore a few examples.
For instance, linking three 1.5-volt batteries in series produces a total output of 4.5 volts. Parallel Connection: Parallel batteries maintain the same voltage as an individual battery. If three 1.5-volt batteries are connected in parallel, the output remains at 1.5 volts. Capacity：
