How to choose drone battery?

Nowaday, drones are very popular and develop very fast, and now they have been used in almost every field of life. From safety to entertainment, drones have become an integral part of our lives. Just like anything else, it also needs power to move on, which is the heart of the device’s beating: the drone battery.

They are responsible for providing the power needed for the execution of the drone.

However, one thing you need to remember is that, like humans, every drone is different. This is why we need to check some parameters to select these batteries. And for the drone, it always use the lipo batteries for its light weight, high discharge rate and high-magnification.

Choose drone battery

*Battery capacity

The battery specification you need to pay attention to is the battery capacity. Many things depend on this capability, including the total flight time of the drone. So, what should be the right battery capacity?

We think it is best to choose the battery with the largest battery capacity. However, one thing you need to keep in mind is that even if you choose the battery with the largest capacity, you must still ensure that its weight combined with the weight of the quadcopter does not exceed the maximum takeoff weight. In addition, it is recommended that you carefully check the specifications of the drone, especially the motor thrust, in order to select the appropriate product.

Always remember that the discharge rate of the battery depends on the capacity, because it represents the life of the battery.


Before  being used to your drone, the battery needs to meet many conditions, and the one on the list is the size. Now, when we talk about the size of the battery, you need to understand that it is not only the physical size of the battery, but also the capacity.

Now, let’s focus on weight and size. Indeed, when we strive for longer flight times for drones, we usually choose the battery with the largest capacity. However, here you also need to check whether the battery is compatible and will not cause any problems during takeoff. As far as the maximum takeoff weight of the drone is concerned, the weight of the battery is the determining factor.

In addition, the battery of your choice must fit easily into the drone. Here, you need to carefully check the length and width of the drone battery compartment in order to accurately obtain the size. Finally, to ensure that you get the correct drone battery, it is best to carefully check the maximum weight of different drones to understand which drones to choose for your product.

*Cell count

One of the most important aspects to cover when choosing a battery is its battery level or battery voltage. The special function in the battery cannot be ignored because of the simple fact that the voltage is proportional to the power generated by the motor. Therefore, you will find that a battery with a higher or higher voltage can help the motor provide more power. However, you should know that these batteries are usually heavier than usual.

If you are looking for a specific method to select a battery based on voltage output, then there is no choice. Although a prudent method of selecting the correct voltage required by the drone can be achieved by comparing the efficiency with the drone’s motor thrust meter.

What we can tell you for sure is that a battery with a better number of batteries will definitely provide a better voltage, but the negative effects that come with it are higher costs and increased battery weight.

Finally, the biggest question to answer when choosing battery voltage is the number of UAV motors. In addition, you need to emphasize the fact that the electronic equipment and electric motor of the drone used can support the voltage selected for it.

You must know that some UAV motors are very voltage-sensitive, and any changes will adversely affect them.


If you have ever tried to install a battery on a drone, then you must know that this is a pain. For this particular reason, you will see people trying to find a good battery connector and use it for drones. These connectors can provide you with a double advantage.

First, it not only helps you easily replace the battery, but also allows you to choose to use the same battery (if you plan to create a new drone in the future). There are pretty good connectors on the market, so choose wisely when deciding which connector to choose for your drone. But one thing you should keep in mind is to stick to your choice and do n’t change these connectors unless absolutely necessary.

* Discharge rate

Not many people know that the performance of a drone depends on the discharge C rating, which is why most people tend to ignore this particular function in the battery. Many experts will tell you to check to make sure you only buy a battery with the best discharge C rating.

For example, if you use a battery with a low discharge rate, the drone is likely to perform poorly because the electric motor will not be able to produce the best power for it. At the same time, you will find that this will damage the battery, which is something you want to avoid. To ensure that you know what you are doing, we recommend that you also read articles about the battery life of the drone and how to use the battery. To make the most of it.

On the other hand, if you install a battery with a higher discharge rate, the drone will bear additional weight when in the air, which will actually reduce the overall flight time of the drone.

Assessing the battery’s discharge rate is a tricky job, but some steps may help you find a solution. The first way to find a suitable discharge rate is to check the specifications of the motor and evaluate the maximum current consumption. A simple method for calculating consecutive draws is as follows:

Maximum continuous current consumption = battery capacity X discharge rate.

* How many batteries?

One of the questions you should think of when looking for batteries is how much battery your drone actually needs. This is a related question that you should answer wisely, because it has its own advantages and disadvantages.

For example, if you want to install some extra batteries, it basically provides extra protection for the drone in case one of your batteries fails during the flight.

Therefore, in this case, you will be able to land the drone with other batteries until you manage to find out the problem. In addition, it also provides the option to replace the old battery, which is an absolute advantage for you. It is a better idea to use two chargers here because you will be able to charge two batteries at the same time, which means you will save the total charge time of the battery.

Now let us look at the negative impact of this arrangement. The first problem you will face here is the complexity of the arrangement. The complexity we are talking about is the installation and wiring of the battery on the drone, you should check it carefully.

Secondly, there is no doubt that buying two batteries at the same time is definitely more expensive than choosing a single battery. Finally, it must be said that if you consider using two batteries, it is likely to cause the maximum takeoff weight of the drone, which is not good news for you.

Finally, we can tell you that the choice of the number of batteries will ultimately depend on the type of drone you are using or will use.

*Replacement battery

The reason why you should pay attention to the possibility of replacement is that if for some reason you cannot find commonly used batteries, make sure you know the next best option.

In addition, you will find that these alternative products are generally cheaper than branded alternative products, and can even provide excellent performance. However, please remember everything we have discussed so far, do not underestimate this matter


When we talk about the brand of batteries, it is wise to let you know that the brand of the battery and the brand of the drone are very important.

First let’s talk about batteries. If you ask any drone enthusiast, they will tell you the importance of the brand. There are many brands of batteries on the market known for their performance and quality.

This is definitely an amateur mistake, and I believe you do not want the drone to fall out of the sky due to a battery failure.

Now, let’s focus on the brand of drone you are using. After some research, you will find that some drones tend to use specific batteries specified by the manufacturer. These proprietary batteries mainly provide a more unique feeling for drones. The problem here is that as far as the battery is concerned, it may limit your choices, which may bring an unfavorable market to the drone.

Therefore, it is your responsibility to find out which battery the drone needs to fully utilize the battery.

Tips and tricks to extend battery life


A very clever way to save the battery is to charge it at the right time. If you are using rechargeable batteries, you should know that they tend to lose charge even when not in use, so you should charge them every other day to maintain their shape. One thing you should remember is that you should only charge the battery for a few hours before putting it into service.

* Appropriate conditions

It is a good idea to try to drive a drone under appropriate weather conditions. The reason we put pressure on these conditions is that if the drone is driven under adverse conditions such as cold or rainy weather, it may put pressure on the battery.

Drones will spend more energy on flying, which may seriously damage battery life. Driving a drone when the weather is clear is a wise choice because it allows you to enjoy the experience while flying longer.

* Leave the camera

It is true that the camera on the drone can help you record the flight situation and the surrounding area, but unless you absolutely need it, we recommend that you can abandon it. It not only reduces the weight of the drone, but also releases the pressure on the battery.

You must understand that the camera on the drone is battery powered. Therefore, by removing it, you will have more time to ride the drone. In addition, if you want to use the drone for entertainment rather than shooting, we recommend that you consider the FPV system, which is equipped with a lighter camera and can “take you into the pilot’s cockpit” during the flight.
