Everyone is buzzing about the most recent drone that the industry leader has released, with its vertical camera and innovative design.
However, only a few mention the DJI Mini 3 Pro battery. How much voltage is it? How is it charged? What are its main features?
We will give you all that information and more in this article.
The DJI Mini 3 Pro battery can be charged in one of two ways: by connecting the USB cable directly to the drone, or by using the new two-way charging hub to charge up to three batteries sequentially.
The fact that this drone can be used with two batteries, even if the Plus version is only accessible in a few regions, has struck many as a big surprise.
Maximum flying time with the basic version is 34 minutes, while with the Plus version is 47 minutes.
If you are looking for information about your new Mini 3 drone battery, you are in luck, as we will cover everything you need to know in this guide.
What battery does the DJI Mini 3 Pro use?
The Mini 3 Pro uses the most recent DJI Intelligent Flight Battery, as is the case with every other DJI drone.
But this time, the new best-selling product from the Chinese manufacturer may also use a different battery, the Intelligent Flight Battery Plus, which provides longer flight times.
However, these new batteries also come with a couple of downsides:
- They are only available for purchase in certain territories.
- Using them makes the aircraft weigh more than 250 g.
On paper, this is how long each DJI Mini 3 Pro battery lasts:
|Intelligent Flight Battery
|Intelligent Flight Battery Plus
The Mini 3 Pro’s standard battery has two cells with a voltage of 7.38 V and a capacity of 2453 mAh. The Intelligent Flight Battery Plus has two cells as well and produces 7.38 V.
However, it has a higher amperage of up to 3850 mAh. Because of this, it provides a flight time that is up to 10 minutes longer than the standard version.
Mini 3 Pro Intelligent Flight Battery Features
We have seen the main difference between the standard battery and the Plus version.
Now, let us take a look at the main features offered by these new intelligent flight batteries.
- Balanced Charging: When the battery is charging, the cells are automatically balanced for equal filling.
- Auto-Discharging: When the battery has been inactive for more than a day, it automatically drains itself to prevent swelling, bringing the charge down to 96%. After nine days of inactivity, this will be reduced to 60%.
- Overcharge Protection: When the battery is fully charged, it will stop charging further.
- Temperature Detection: The battery will only charge when it is between 41° and 104° F (5° and 40°) to prevent damage. If the battery reaches 131° F (55° C), the charging process will end automatically.
- Overcurrent Protection: The battery will immediately stop charging if an excess current is detected.
- Over-Discharge Protection: When the battery is not in use, the discharge automatically pauses to prevent excessive discharge.
- Short Circuit Protection: If a short circuit is detected, the power supply is immediately turned off.
- Battery cell damage protection: When a battery cell gets damaged, a warning will be displayed on DJI Fly.
- Hibernation mode: The battery enters Hibernation mode to prevent over-discharge of the battery cell voltage to less than 3.0 V or the battery level to less than 10%. You must charge the battery to start it up.
- Communication: Intelligent flight batteries transmit information on voltage, capacity, and current to the aircraft. These data can be seen in the DJI Fly app.
How to Charge the DJI Mini 3 Pro Battery?
DJI recommends that you fully charge the batteries every time you use them. To do that, only official cables and chargers should be used.
Always remember that charging LiPo batteries can be dangerous. Nothing should happen, but it is recommended that you always keep an eye on them when they are charging.
Note: Do not leave your LiPo batteries unattended.
If the batteries catch fire, do not use water to extinguish the flames, since this is a Class D fire (combustible metals).
The use of a dry powder extinguisher is the correct method for putting out this kind of fire. The fire and any oxygen it has will be smothered by this extinguisher.
There are two ways that you can charge your DJI Mini 3 Pro battery:
1. Charging the DJI Mini 3 Pro Battery through the New Two-Way Charging Hub
The new Mini 3 Pro two-way charging hub is included in the Fly More Combo, but can also be purchased separately for $49.
This accessory can charge up to three intelligent flight batteries sequentially, which means one after the other. They are charged from high to low power levels.
When connected to AC power through a USB charger, a new interesting feature of the two-way charging hub is that you can now also charge the remote controller through it.
First, it will charge the batteries, then the remote.
A step-by-step guide to charging your batteries through the Two-Way charging hub:
- Remove the DJI Mini 3 Pro battery from the drone.
- Carefully insert the batteries into the charging hub until you hear a click.
- Connect the two-way charging hub to a power outlet using the official DJI cable and charger, such as the DJI 30W UBS-C charger.
- The charging process will start in the battery with the highest power level.
- The other batteries will follow.
- The remote controller will be charged if it is connected to the two-way charging hub after the batteries have finished charging.
Charging the DJI Mini 3 Pro Battery through the Drone
You may charge a single battery while in the drone if you only have one.
Follow the steps to do it:
- Ensure that the battery is properly fitted in the drone’s battery compartment.
- Connect the DJI 30W portable charger or the USB Type C cord to the back of the drone.
- Connect the DJI 30W portable charger to a power outlet or connect the USB Type C cord to a power bank. Verify that the input voltage ranges from 100 to 240 V.
- Wait until the battery finishes charging. The LED lights included can be used to determine the state.
How long do DJI Mini 3 Pro batteries take to charge?
With the new Intelligent Flight Flight batteries included with the DJI Mini 3 Pro, DJI has slightly improved not only the flight times of the aircraft but also the time required to fully charge them.
Charging the standard battery with the DJI 30W USB-C charger should take around 1 hour and 4 minutes. This is 18 minutes shorter than what it takes to charge the battery of the Mini 2.
If you own the Fly More Combo package, it will take you 3 hours and 12 minutes to fully charge all batteries.
Due to its larger capacity of 3850 mAh (compared to the standard battery’s 2453 mAh), the Plus battery takes a little longer to fully charge.
As a result, it will take 1 hour and 41 minutes to fully charge one Plus battery.
If you have 3 Plus batteries, it will take you 5 hours and 3 minutes to fully charge them.
Are you a Professional?
If you work with drones professionally, you know that three batteries are frequently insufficient.
So, if you want to use additional batteries, here is a table that will help you determine how long they will need to charge:
|Number of Batteries
|Charging Time Standard
|Charging Time Plus
|1 hour 04 minutes
|1 hour 41 minutes
|3 hours 12 minutes
|5 hours 03 minutes
|6 hours 24 minutes
|10 hours 06 minutes
|10 hours 40 minutes
|16 hours 50 minutes
|25 hours 15 minutes
How do you know when the battery is charged?
At this point, you should be charging your batteries, either through the two-way charging hub or by plugging the USB cable directly into the drone.
So, how will you know when they are fully charged?
Fortunately, intelligent flight batteries, unlike the LiPo batteries of FPV drones, come with LEDs that display the battery level. Take a look at the following graph:
|2 LEDs Blinking
|0% to 50%
|3 LEDs Blinking
|50% to 75%
|4 LEDs Blinking
|75% to 100%
|4 LEDs On
How to insert and remove a DJI Mini 3 Pro battery
You wouldn’t believe how frequently people fail to correctly insert or remove the battery from their drones.
If that has not happened to you yet, you are either a novice pilot or a superbly cautious one.
As you may expect, improper battery insertion in a drone can have disastrous results. As a consequence, while performing this work, you should always be careful and pay close attention.
Inserting the battery is a bit easier than removing it. To properly insert it, simply let it slide inside its compartment until you hear a clicking sound. This will indicate that the battery has been securely fastened.
If you did not hear the clicking sound, pull it out a bit and insert it again until you hear it.
You need to be a little extra cautious while removing the battery because if you pull too hard, you can lose your grasp and the battery will fall.
Press the textured part of the battery buckles that are placed on the battery’s sides, then pull the battery out to remove it.
Note: (1) Do not insert or remove the battery while the aircraft is powered on. (2) Make sure the battery is securely attached before operating the aircraft.
How long will a DJI Mini 3 Pro battery last in reality?
We have already seen how long the DJI Mini 3 Pro batteries should last, but only according to DJI. As you know, the flight times given by the manufacturer are always determined by specific flying conditions.
In reality, a typical battery should provide us with about 20 minutes of flight time, with a maximum of 34 minutes when conditions are the same as in DJI tests.
Have a look at the video below for some reference.
Precautions to take when using Mini 3 Pro batteries
This guide to the DJI Mini 3 Pro battery would not be complete without this important section.
LiPo batteries can be dangerous, the same as operating your drone recklessly, so some precautions must be taken when using them.
- Flying in severely cold weather, 14° F to 41° F (-10° to 5° C), drastically reduces battery capacity. Before starting your drone’s operation, hover still for a bit to heat the batteries and prepare it for whatever task you have in mind.
- Temperatures below 14° F (-10°) are too low for Intelligent Flight Batteries to work.
- Batteries must be above 68° F (20° C) to ensure proper functioning.
- Low-temperature settings lead to a decreased battery capacity, which lowers speed resistance performance.
- Fly carefully at high sea levels.
- The temperature of the environment has an impact on how quickly batteries charge. They need to be charged at a temperature of 77° F (25° C), if possible.
- The DJI Mini 3 Pro two-way charging hub is compatible only with standard and Plus batteries. Do not try to charge other batteries with it.
- When charging batteries with the two-way charging hub, do not touch the metal terminals.
- Intelligent Flight Batteries cannot be charged if the aircraft is powered on.
- An intelligent flight battery shouldn’t be charged right away after usage. Hold off till it cools.
- Fully charge the batteries at least once every 3 months to maintain their health.
- When traveling with batteries, keep their power level low. It is recommended to discharge them to 30%.
That is all for today, pilot! We hope that you have a better understanding of how to properly use your DJI Mini 3 Pro batteries.
