![]() Therefore, thinner wires can connect the batteries because there is a lower current draw and the voltage drop across the system is lesser than in a parallel connection. A thorough study of the pros and cons of wiring batteries in parallel vs series will guide you in choosing the most suitable one for yourself.Įlectric car battery pack image 2.1 Pros and Cons of Batteries Connected in SeriesĪs discussed earlier, voltages are summed up while the amp-hour remains the same when you connect batteries in series. ParallelĮach of these methods of connection has its peculiar pros and cons. Pros and Cons: Batteries Connected in Series vs. In the next section, we will discuss the pros and cons of connecting batteries in series vs parallel. The old ones will affect the new ones and drag them down. Also, avoid mixing and matching new and old batteries together when connecting your batteries in parallel. Connecting batteries with different capacity ratings in parallel is dangerous and may eventually damage your batteries. Just like the series connection, checking the capacity rating of your batteries before you connect them is essential. For instance, two 12V 200Ah lithium batteries connected in series will provide 12V and 400Ah. ![]() Connecting batteries in parallel increase the amp-hour while the voltage remains the same. Parallel batteries are used when you need to improve the amp-hour while maintaining the same voltage level. This is very important because mixing and matching batteries with different capacity ratings is dangerous and may eventually damage the batteries. Also, wiring your batteries in series is easy to build and repair.īefore wiring your batteries in series, one critical thing to do is carefully check each battery’s voltage and ampere ratings. This connection method is proper when there is a need to increase the voltage to support applications requiring higher voltage. For instance, two 12V 200Ah lithium batteries connected in series will provide 24V and 200Ah. A good lithium light EV battery passes the strict reliability test of important components, ensuring the stability of the whoBatteries are connected in series to increase the voltage while the amp-hour remains the same. Hence, the need to know the difference between wiring batteries in parallel vs series. ![]() Both series and parallel connections help to increase the overall available energy (i.e., watt-hours), but they achieve this in different ways. ParallelĪ multiple-battery system can be connected in series or parallel, but it is crucial to understand the difference between the two before you proceed with the process. Classification of Battery Connection Modes: Batteries in Series vs. Let’s begin with the classification of battery connection modes. In this article, we will discuss wiring batteries in series vs parallel and which is suitable.
