The battery is one of the key factors that guarantee the normal takeoff of the drone. How to add its life is worthy of every drone owner. The drone battery has a significant feature discharge than the mobile phone battery.

The drone battery is to be discharged to meet the use requirements of the drone in different environments. For example, when the aerial photography, if you encounter a strong wind, then you want to battery Can 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.

Be sure to pay attention to the following points in the use of drone batteries, the correct way to use is the best way to extend battery life. First, 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-ion battery pack, check the voltage of the battery pack for each battery unit, and the same work should be made every 10 charge and discharge. 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 with a safe location. 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 battery, can not be filled for more than 3 days, if more than one week is not let it, some batteries can not drums, but some batteries may not be drums, but several times are preserved, 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 25c, 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 it is found that the battery is broken when the battery is used for a while, it is necessary to pay attention to the electric soldering iron, do not 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, the battery is placed outside, and its discharge performance will be greatly reduced. If you still have to fly during the normal temperature, then you will have problems. 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. .
