Each configuration has its advantages and considerations. In series, the voltage increases while capacity remains constant; in parallel, capacity adds up while voltage stays the same. Charging batteries in series can be more complex as each battery needs to reach the same level of charge for optimal performance.
Wiring batteries in both series and parallel configurations is possible and is so beneficial that be used in many power systems.

When it comes to comparing the safety of batteries connected in parallel versus series, there are important factors to consider. In a parallel connection, each battery maintains its voltage while increasing the overall capacity. This setup can be safer because if one battery fails, the others will continue working.
Capacity: Parallel connections of LiFePO4 batteries enhance the total capacity of the battery pack. For instance, connecting four 100Ah batteries in parallel results in a total capacity of 400Ah. Conversely, series connections do not increase the overall capacity; they only increase the voltage output.

Differences between the connections are given below: A series connection of panels means batching of panels in a line in order of positive to negative. So, the solar array voltage increases but amperage remains the same. Below are the steps for this connection:
Keep in mind that there are positives and negatives to each system. While it may be easier to wire your solar panels in series, a disruption to one of the elements will disrupt the entire circuit, so it is less reliable. On the other hand, panels connected in parallel need larger, more expensive wire (and more of it).
For connecting panels in either series or parallel, we need to start with wiring. Any PV panel will have male and female MC4 connectors, i.e. positive and negative terminals. Differences between the connections are given below: A series connection of panels means batching of panels in a line in order of positive to negative.

Lithium batteries are connected in series when the goal is to increase the nominal voltage rating of one individual lithium battery - by connecting it in series strings with at least one more of the same type and specification - to meet the nominal operating voltage of the system the batteries are being installed to support.
In a parallel connection, the batteries are linked side-by-side. This configuration keeps the voltage the same but increases the capacity. For instance, connecting two 3.7V 100mAh lithium cells in parallel will result in a total capacity of 200mAh while maintaining the voltage at 3.7V.
Batteries in series are connected end-to-end in such a way that the high potential terminal of one battery connects to the lower potential terminal of the given battery.
