If you have ever had any kind of experience with batteries then you might have heard about the term’s series and parallel connection. But the majority of people wonder about what it means.?Your battery performance depends on the all these aspects and your knowledge about the basics.

So, lets know more about how to run batteries in series-connection, rules, and methods.

Is it better to connect batteries in series or parallel?

A lot of people wonder what is better between the two options. Either connecting batteries in a series or a parallel way. Generally, the method you will opt for depends on the requirements of the applications you need to operate.

Hence, let’s have a look at the pros or cons of the series and a parallel connection for the batteries.

Connecting batteries in a series connection: is it beneficial?

Connecting batteries in a series connection are generally considered to be a good option for those applications which are quite large. Or for the ones that require a high voltage. A high voltage means up to or more than 3000 watts.

The need for a higher voltage means that the system for current is lower. That is why in such cases you can use thinner wiring. The loss of voltage will be also lower. Meanwhile, there might be a lot of advantages to the series connection.

But there are some cons as well. They are quite minor but it is important for the users should know about them. Like, when you do this all the working applications have to work at a higher voltage. Hence, if a working requires a very high voltage, then you will not be able to operate them without using a converter.

Connecting batteries in a parallel connection: is it beneficial?

Well, have you ever wondered about a wiring system and its working principle of it? If you have not then you should know that the voltage that is offered then stays the same. But with it, you can also operate your applications for a long time since the capacity of the appliances has been increased.

As far as the cons are considered then placing the batteries in a parallel connection can allow them to make them work for a longer time. Moreover, the voltage that is lowered means that the current is higher, and the drop of the voltage occurs more. However, it might be difficult to offer the powering of large applications. Also, you will need much thicker forms of cable.

Batteries in parallel Vs series: what is more convenient?

In the end, not any of the options are ideal. Selecting to wire the batteries in the series Vs parallel usually depends on what is ideal for you.

However, there is another option if we talk about convenience. That one is known as, a series and a parallel connection. This does not mean that you should wire your batteries in either of the series and parallel. That will also shorten your system. This connection of series and the parallel connection is established by the wiring of various batteries in a series connection.

Afterward, you also have to make a connection of parallel batteries. A connection of parallel and a series connection is established and by performing this you can easily increase the voltage and capacity of it.

How do you hook up 12-volt batteries in a series connection?

After knowing about the factors of whether the connection of a series is better than parallel the next thing people want to know is how do you set up a 12-volt battery in a series connection.

Well, it is not something rocket science. You can easily learn it by the means of the internet or technical books. Hence, some of the points that can be able to let you set up a 12-volt battery in a series connection are mentioned below.

Whenever you want to join the batteries in the series connection then you need to make a power source of 12 volts.

Then you have to join them in a series connection way. Hence, for joining the batteries you need to identify the terminals.

Once you recognize the terminals as the positive and negative ends then connect the positive end to the negative end of either battery.

Increasing Power While Joining the Batteries in a Series Connection

Indeed, the connection of 12-volt batteries in a series connection increases the voltage. However, it does not offer any guarantee for increasing the overall capacity of the amp-hour.

Usually, all the batteries in a series connection should have a similar amp-hour. However, the connection in a parallel system increases the current capacity of the overall look. Hence, these are the factors that need to be known.

What is the rule for connecting batteries in series?

There are several things that you need to take care of while connecting the batteries in series. Meanwhile, some of those tips and rules are mentioned below.

Recognize the Terminal Ends

You need to take a look over the ends of the terminal. Without this, the risk of a short circuit gets much higher. Therefore, always make sure to know the ends of your terminal.

Learn About the Positive and Negative Ends

The other factor that should be looked upon or must be followed is to identify the positive and negative ends. If the ends are not properly connected then the energy of both ends can cancel out each other. Hence, the rule is to always connect the positive end of the battery to the negative end. And the negative end of the battery to the positive end.

These rules should be followed for inserting your Batteries in a series connection. If you do not follow them the chances of your circuit not generating power are much higher.


There are two types of connection that are, either series or parallel. These two can be combined to form a series and a parallel connection. It depends on your working appliances that which connection might suit them best.?
