UAV aerial photography battery maintenance skills

UAV aerial photography popularization of large-scale programs is an ingenious way to maintain UAV aerial photography batteries. Looking at the development history of UAVs in recent years, we can find that UAV aerial photography has gradually become popular in large-scale projects. Its convenient operation, simple structure and unique shooting perspective have captured the hearts of many image creation agencies. When it comes to battery usage, there are six that are not mandatory. Proper use is the best way to extend battery life. 1. However, some of the chargers that require charging, the full power function after the charger is not perfect, causing the 4.2V single battery to not stop charging, in addition, after some chargers are used for a period of time, because the components are aging, it is easy to stop. Therefore, someone must take care of the lithium polymer battery. When it is found that the charging time is too long, check whether the charger has failed. If the battery is not removed as soon as possible, otherwise the lithium polymer battery will be overcharged, which will affect the battery life and light weight. , There was a direct fire. In addition, when charging, be sure to charge the battery according to the C number or lower C number, and not exceed the specified charging current. 2. The discharge curve of the battery shows that the voltage drops rapidly at the beginning of discharge, but the voltage drops slowly between 3.9V and 3.7V. But once the voltage drops to 3.7v, the speed of the voltage drop will increase. If the control is not good, it will lead to over-discharge, lightly it will damage the battery, and low voltage will cause explosion. Some aeromodelling friends will use it every time they fly because they have few batteries. This kind of battery has a very short lifespan. Their strategy is that as long as one minute of flight, the life span will be extended by one cycle. It is better to buy two batteries than to exceed the limit each time. In order to make full use of the battery alarm, the alarm should be lowered as soon as possible. 3. There is not enough power to save. If the battery is fully charged, it cannot be stored within 3 days after being fully charged. If it is not discharged for more than a week, some batteries will be directly charged. Therefore, the correct way is to charge the battery after receiving the flight mission. If there is no flight mission within 3 days after the battery is used, please charge the single voltage to 3.80~3.90v and save it. After charging, the battery cannot fly due to various reasons. The battery is discharged to 3.80~3.90V within 3 days after charging. If the battery is not used within three months, the battery will continue to be stored after charging and discharging to extend the battery life. The battery should be stored in a cool environment. Regarding long-term storage of batteries, it is best to put them in a sealed bag or a sealed explosion box. The recommended ambient temperature is 10~25℃. 4. No skin damage. The battery shell is an important structure to prevent battery explosion and leakage fire. The battery should be handled with care. When fixing the battery on the airplane, please fasten your seat belt. Because it is possible to make a large dynamic flight or damage the machine, the battery will be thrown out because the tie is not tight, so it is easy to cause damage to the battery skin. 5. There is no short circuit. This situation often occurs during the maintenance and transportation of the battery welding line. A short circuit can cause the battery to catch fire or explode. When it is found that after a period of use, the battery has broken wires, re-weld the wires. Pay special attention to the electric soldering iron not to touch the positive and negative electrodes of the battery at the same time. In addition, during the transportation of the battery, the best way is to cover each battery with a self-sealing bag and place it in an explosion-proof box to prevent short-circuit or broken skin collisions and collisions. The positive and negative electrodes of the battery are in contact with other conductive materials at the same time. The material is in transit. 6. Don't catch a cold. This is a principle that many pilots ignore. There are often low temperatures in the north or high altitude areas. At this time, if the battery is placed outdoors for a long time, its discharge performance will be greatly reduced. If the flight time is flying at room temperature, there is a problem. At this time, the alarm voltage should be adjusted higher (for example, the single alarm voltage is adjusted to 3.8v), because in a low temperature environment, the voltage drops very quickly, and when the alarm sounds, it will drop immediately. In addition, the battery should be insulated. The battery should be placed in a warm environment before takeoff, such as indoors and outdoors.
