The DJI Mavic Mini 2 was released in November 2020, one of the best drones of the year, and the Mini 2 has become DJI's best-selling drone. One of the most impressive features of the DJI Mavic Mini 2 is the battery life; it has a flight time of 31 minutes, which is longer than most high-end drones. We will look at the intelligent flight battery of the Mini 2.
The DJI Mavic Mini 2 battery is 3.85 inches long, 2.36 inches wide, 1.65 inches high, and weighs 3 ounces. The capacity of the Mini 2 battery is 2250 mAh; it is a 2S LiPo battery with 7.7 volts rated voltage and 8.8 volts charging voltage limit. The maximum charging power is 29 watts.
One of the factors that determine the weight of a drone is the battery, and the DJI Mini 2 has a light battery pack, which makes the drone weigh less than 250 grams. This means you do not have to register the drone with the FAA before operating it.
What Battery Does The DJI Mini 2 Use?
The DJI Mini 2 comes with DJI's best drone battery, an intelligent flight battery, a LiPo 2S 2250 mAh battery pack. All drone operators know that LiPo batteries are the best; they contain polymer electrolytes instead of liquid electrolytes. There is a conductive semi-liquid gel in the electrolytes that makes the battery charger faster.
The LiPo 2S, 2250 mAh battery in the DJI Mavic Mini 2, is also lightweight, a prominent feature of LiPo batteries. You will notice that the battery is 2s, which means that there are two cells in a series in the battery. Each cell has a nominal voltage of 3.7 volts, so the series has a total voltage of 7.4 volts.
The LiPo 2S 2250 mAh battery has a rating voltage of 7.7 volts, as we mentioned earlier, and a charging voltage limit of 8.8 volts. The milliamp-hour of the DJI Mavic Mini 2 battery is 2250, and an average LiPo battery uses 100 milliamps per hour, so the Mini 2 battery can work for about 22.5 hours.
The battery also features an in-built battery management system (BMS), which makes the battery charge and discharge properly with any of the cells getting damaged. The BMS also makes the battery go into hibernation mode when stored for a long time.
The intelligent battery management system makes the battery function well and safely with the drone. It also monitors the battery status and sends reports to the IMU, stabilizing the dispatched energy and calculating the remaining battery time for the drone to remain in the air.
How To Charge The DJI Mavic Mini 2 Battery
One of the most important things to know about the DJI Mini 2 battery is properly charging it. There are two ways to charge a DJI Mavic Mini 2 battery, by using the 2-way battery charger or a drone. The 2-way battery charger is also referred to as the charging hub.
Charging DJI Mavic Mini 2 Battery Via Drone
This is an easy option for those without a charging hub and extra batteries; it is also a quick way to charge the battery safely. All you have to do is place the battery in the drone compartment and connect the drone to a charging brick using a USB Type-C cable. You can use the USB Type-C with the drone or any other type C cable.
Charging DJI Mavic Mini 2 Battery Via Charging Hub
This is the best, safest, and fastest way to get the battery of your DJI Mavic Mini 2 drone charged. The 2-way battery charger is designed so that your batteries are charged sequentially. With a charging hub, you can charge all three batteries of your drone overnight, and by morning, they will all be fully charged.
The 2-way battery charger charges sequentially; the battery with the highest charge level charges first, the battery with the mid charge level is next, and then the battery with the lowest charge level. You might be wondering why it is called a 2-way charger; this is because it can also charge other USB-powered devices.
To charge a DJI Mavic Mini 2 battery with a charging hub, you need to do the following;
- Place all the batteries in the charging ports; the battery is properly and securely docked in when you hear a click sound.
- Next, use a USB Type-C cable to connect the charging hub to an 18-watts adaptor; you can also use the charging brick of any android or iPhone phone.
- After connecting the charging hub to an adapter, leave it overnight for a full charging cycle to be complete on all batteries sequentially.
- There are LED lights on the charging hub; they indicate that all three batteries are fully charged; check it.
How Long Does The DJI Mini 2 Intelligent Battery Take To Charge?
It takes time for a DJI Mavic Mini 2 intelligent battery to be fully charged; this is why it is best to always use an 18-watt charger for the battery. It takes approximately 60 minutes for the battery to be fully charged when using an 18-watt charger. This time is also affected by the humidity and temperature.
As long as humidity and temperature are in ideal conditions, it will take an hour for a Mini 2 battery to be fully charged. It will take longer if these are not in ideal condition. The temperature required for the battery to charge is 5 to 40 degrees Celsius (41 to 104 degrees Fahrenheit).
Using a charging hub will take about 240 minutes for all three batteries to be fully charged as long as you use an 18-watts charger. This means it will take about 80 minutes for each battery to be fully charged. If you use a charger with less than 18-watt output, it will take longer for the batteries to be fully charged.
The major reason DJI Mavic Mini 2 battery charges faster is the intelligent battery management system. The BMS supports fast charge, and in this mode, the LED lights will flash rapidly. If you are charging in normal mode, the LED lights flash slowly.

How Long Does The Battery Last On The DJI Mini 2?
After waiting 4 hours for your Mini 2 intelligent batteries to be fully charged, you want to know how long each battery will last when you use it with the DJI Mavic Mini 2. The DJI Mini 2 intelligent battery can last for about 31 minutes, according to the information on DJI's website.
Of all drones in the market, the DJI Mavic Mini 2 has the longest flight time; other drones like the Autel Robotics EVO and the Sim Too Pro have a total flight time of about 30 minutes.
Features of the DJI Mavic Mini 2 Intelligent Battery
The intelligent battery management system in the DJI Mavic Mini 2 battery makes the battery unique and the best in the drone industry. The BMS protects the battery from risks that can reduce the battery life. Some of the smart features are;
Hibernation Mode
This puts the battery in hibernation or sleep mode to prevent it from over-discharging when stored for a long time.
Overcharge Protection
This prevents the battery from damaging when it is charging overnight. Due to this feature, the battery stops charging once it is fully charged. Other features are auto-discharge, balanced charging, and temperature management.
