The battery is one of the key factors that guarantees the normal takeoff of the drone. How can we increase its service life?. According to industry insiders, drone batteries and mobile phone batteries are lithium batteries.

It is the power source of the equipment, and the safety performance requirements are also high. However, there are differences in the two, and the drone battery has a significant feature than the mobile phone battery - discharge, the drone battery needs to be discharged to meet the requirements of the drone in different environments, such as aerial photography, If you encounter a strong wind, you need a battery to make a corresponding compensation to make a large current discharge, to ensure the location of the drone. Because the use requirements are different, the life of the drone battery is relatively short.

Industry insiders also give a few practical recommendations to lithium battery users: 1. The discharge curve of the discharge battery indicates that the voltage drop is faster when the discharge is started, but the discharge is between 3.9 ~ 3.

7V, the voltage drop is not fast. However, once it is reduced to 3.7V, the speed of the voltage will speed up, the control is not good, resulting in over-delivery, light damage, the battery, the voltage is too low, the oil.

Some models have been over, so they will be over, so that this battery is very short. The strategy is, try to fly less than one minute, life will fly a loop, buy two pieces of battery, do not fly the battery to exceed the capacity limit each time. To make full use of battery alarms, alarm should land as soon as possible.

Second, but charge 1, use a dedicated charger. This charger can be a lithium ion or lithium polymer charger, both very close. Partial mobile phone charger can be used to charge lithium polymer battery.

This will not damage the battery. 2, accurately set the number of battery cells in the battery pack. In a few minutes, you must carefully observe the display of the charger, and the number of batteries in the battery pack will be displayed.

If you don't know, you should not charge or use the charger you are familiar with. 3, first charge a new lithium battery group, check the voltage of each battery cell of the battery pack, and then every 10 charge and discharge should also do the same work. This is absolutely necessary, and a voltage imbalanced battery pack will still burst when the number of batteries is selected correctly.

If the battery cell voltage is more than 0.1 volts within the battery pack, you should charge the voltage of each battery to 4.2 volts, respectively.

If the voltage difference of the battery cells exceeds 0.1 volts after each discharge, it means that your battery has failed and should be replaced. 4, no one looks not to charge 5, place the charging battery and charger using safe position.

6, generally no special explanation of the manufacturer, charging current should not exceed 1C. Now supports large current discharge cells also support more than 1C current charging. But it will greatly shorten the life of the battery, buy 3 batteries alternately charged than buy a battery, more cost-effective.

Third, less than the electric storage battery, can not be filled for more than 3 days, if more than a week is not let it, some batteries can take the bag, but some batteries may not be drums, but after a few times, after storage, the battery May be scrapped directly. Therefore, the correct way is that after receiving the flight task, it is recharged, and if there is no flight task within 3 days, please save the single-chip voltage to 3.80 ~ 3.

90V. If there is a mixed electricity, it is not flying because of the various reasons, and it is necessary to discharge the battery to 3.80 ~ 3.

90V within 3 days. If the battery is not used within three months, continue to save the battery charges, so that the battery life can be extended. Battery storage should be placed in a cool environment.

When the battery is stored for a long time, it is best to be placed in a sealed bag or sealed in the release box, it is recommended to have a ambient temperature of 10 to 25 ¡ã C, dry, non-corrosive gas. Fourth, the outer packaging that does not damage the packaging battery is an important structure that prevents the battery explosion and leakage. The aluminum-plastic film of the lithium poly battery will directly lead to the battery to get fire or explosion.

The battery should be lightly put, when the battery is fixed on the plane, the strap should be tight. Because it is possible to do a big dynamic flight or cutting machine, the battery will take out because it is tipped, which is easy to cause battery skin damage. 5.

This situation is not shorted often occurs during maintenance and transportation of battery welding lines. Short-circuit will directly lead to fire or fire explosions. When the battery is disconnected after a period of time, the battery is required to refine the wire, especially paying attention to the electric iron not to contact the positive and negative electrode of the battery.

In addition, during the process of transporting batteries, the best way is that each battery is separately set onto the bag and placed in the explosion-proof box, preventing the positive and negative poles of a piece of battery due to bumps and collisions during transportation. Substance. Sixth, not low temperature this principle, many flying friends will ignore.

There is often low temperature weather in the north or high altitude area. At this time, if the battery is placed outside, its discharge performance will be greatly reduced, and if it is necessary to fly in the flight time during normal temperature, then the problem will be issued. At this point, the alarm voltage should be raised (such as a single-chip alarm voltage to 3.

8V), because the pressure drop in the low temperature environment will be very fast, the alarm will immediately land immediately. There is another way to keep the battery. Before the takeoff, the battery is saved in a warm environment, such as the house, in the car, insulation box, etc.

Quickly install the battery when you take off, and perform a flight task. Try to shorten the time to half of the normal temperature status while flying at low temperature to ensure safe flight. The industry also added that everyone should not blindly choose when buying the drone battery.

Consider the factors such as brand, market heat, evaluation performance, and integrate all aspects of factors to consider the battery that suits you drone. The drone industry is a Chaoyang industry, and the drone battery industry is also a chain Yang industry. It has a broad development prospect.

Lithium batteries will be more and more suitable for all-round use, safer, more intelligent, more popular in future development. In the future, Shenzhen Gripper Battery Co., Ltd.

will continue to develop, combined with electron and battery technology, and vigorously develop products with Tattu brand, meet the needs of different types of drones to ordinary batteries and smart batteries.
