The DJI Drone Phantom 4 flight must not be lower than the minimum temperature

The recommended working environment temperature for consumer-grade aerial photography aircraft is 0 -40, and the working environment temperature for handheld devices is recommended to be 5 -40.

Affected by the characteristics of lithium batteries, the performance of the battery will be seriously degraded when used in a high or low temperature environment, so it is recommended not to use it in an excessively high temperature environment;

If you need to use a drone to shoot in a low temperature environment, you can refer to DJI.

Some tips for using the forum.

With the advent of winter and the drop in temperature, winter flights require special attention. Due to the recent experience of users in various winter flight problems, such as voltage sags, insufficient flight power, and even more serious aircraft crashes. That's why we've launched a safe winter flight guide to help you better capture the beauty of winter.

Working mechanism of lithium battery:

The aircraft is powered by lithium batteries, and the low temperature environment will seriously reduce the performance of lithium batteries. When the battery is exposed to an environment below 15°C, the chemical activity of the battery is significantly reduced, and its internal resistance increases, resulting in a decrease in discharge capacity, and an increase in voltage drop when the battery is discharged. Significant voltage drop (single cell.

Below 3V) there are two major risks: first, the aircraft power system.

The maximum thrust is not enough to sustain the flight; Second, when the voltage drop on the battery reaches a certain level, it may even lead to the danger of power failure of the aircraft. This characteristic is a common problem of lithium batteries, and there is still no perfect solution. Everyone uses mobile phones, tablets.

and other smart devices, which will also shut down in low temperature environments.

UAV lithium battery flight principle:

Aircraft with a larger dead weight inherently require a larger current to maintain power; If the aircraft continues to maneuver and fly, the battery will continue to discharge at high current when climbing at full throttle. Highland area.

Low air pressure due to the thinning of the air.

Aircraft require higher motor speeds to maintain power, and the battery output current will be further increased. The above situation, coupled with the low temperature in winter, further increases the voltage drop of the battery; In severe cases, it may even cause the battery to shut down due to insufficient voltage, causing the aircraft to lose power and crash.

Taking the Phantom3 battery as an example, the schematic diagram of the discharge voltage curve of the aircraft under different temperature conditions is shown in the figure. The lower the battery temperature, the lower the cell voltage after takeoff, and the voltage will slowly return to normal after the battery temperature rises.

If the battery takes off at a low level, the starting voltage of the battery is low, and the temperature of the battery body is low, the voltage will be rapidly lowered, which greatly increases the risk of insufficient voltage. That's why we've always emphasized flying on a full charge.

Battery Winter Use Recommendations:

1.Before flying, be sure to fully charge the battery to ensure that the battery is in a high voltage state.

2.Fully preheat the battery to more than 25 degrees Celsius to reduce the internal resistance of the battery.

It is recommended to use a battery preheater to preheat the battery.

3.After takeoff, keep the aircraft hovering for about 1 minute to allow the battery to use the internal heat.

Let itself fully preheat to reduce the internal resistance of the battery.

The official operating temperature is 0°C to 40°C

Low temperatures can affect the normal operation of machinery, especially the performance of batteries.

Of course, there are also people who fly below zero over the elf series drones, but there are tin foil that adds heat insulation to the outside of them.

There are two reasons why the DJI Drone Phantom 4 can only fly 120 meters high

1. If the drone takes off in the restricted flight area, the maximum altitude is only 120 meters, and it needs to leave the restricted flight area.

In the Novice mode, the Phantom 3 has a flight radius of 150 meters, and after reaching 150 meters, the aircraft will automatically hover, and the flight speed will be limited accordingly.

If the drone takes off in the restricted flight area, the maximum altitude is only 120 meters, and it needs to leave the restricted flight area.

Restricted Flight Zones can be found in DJI Official - Service & Support - Flight Safety Guide.

If it is not in the restricted flight area, there is also a situation where the maximum flight altitude is set to 120 meters, which can be changed to 500 in the advanced settings.

There is a height limit setting that you can adjust.

The common problem is the loss of signal, or hitting the wall or the tree, which is generally caused by the novice's unskill, especially when the opposite direction is not accurate, and the collision is in a hurry.

Advice for newbies:

2 Practice outdoors in an open and unoccupied area.

3 Novices, be sure to have GPS mode, have enough GPS signal before taking off4 Don't fly out of sight! Do not fly out of the range where you can discern the direction of the nose.

Through the flight controller, there is GPS positioning in the flight control to calculate the altitude

The Phantom 4 is pitched by ultrasonic, downward-looking perception and barometer modules.
