  1. The use of agricultural drones in agriculture has become more and more mature. Demand for agricultural drones is increasing around the world.For electric agricultural drones, the use of lipo batteryas a power source has become mainstream.The quality of the drone battery is important. However, any of the best batteries can not avoid the following problems. 1. Battery is prone to man-made damage When they hear that, many battery buyers will say, “Isn’t that nonsense?”. No, that’s not useless. The difference between an agricultural drone battery and other drone batteries is its large capacity. Even if it’s higher than specific energy, its real size ranks first in drone batteries. In the same high-capacity battery, Tattu 22000mah drone battery is 235*172*116mm in volume. Its ratio of specific energy is already very high in the same industry battery solutions. The larger the battery, the less portable it is. It is not easy to remove and put back. Because it is used directly on top of an agricultural drone, it has a “long nose”. That’s the battery’s wire. The wire is secured by welding. However, in the battery use of direct pull and release wires, easy to damage the welding area. The battery is most afraid of bumps and frictions. A bump during transport may cause a short circuit in the outer equilibrium line of the battery. A short circuit can directly cause the battery to burst into flames or explode. At the same time, avoid short circuits of conductive materials that come into contact with both the positive and negative poles of the battery. During transport, the best way is to put the battery in a separate self-sealing bag and placed in an explosion-proof box. So please use it gently. Take care to prevent battery damage! 2. Potions can corrode batteries Agricultural drones in the work, flying will be affected by the residual amount of potions, resulting in uneven phenomenon. The potion in operation is corrosive to the battery. Inadequate external protection can also cause corrosion to the battery. Incorrect use may also corrode the plug of the battery. Therefore, the user must avoid drug corrosion of the battery after charging and actually working. The battery must be placed away from the drug after the job is finished. First, some pesticides are volatile, the battery will encounter moisture, condensate moisture failure. Second, pesticides contain copper, sulfur, phosphorus, nitrogen, chlorine and other chemicals. It is easy for the compounds in the battery to react, causing the battery to corrode bad conditions. Third, some pesticide additives are flammable additives, with the battery placed together to be prone to risk. 3. Risk of fast charging There are many types of drone battery chargers on the market. They have different charging power and charging current. For example, the parameters of a Grepow smart balance charger: Charging current: 0.1-5.0A Charging power: 50W Charging current: The charger can set the charge current value. The lower the value, the smaller the current will be when charging. The higher the value, the greater the charger will charge it at a higher current. A smaller charge is slower, and a larger current is faster. Charging power: The charging power is how much power the charger can use to charge. For example, this model is 50W. If your drone battery charges the current is 3A, but you adjust the charger charge current is 5A. Then, your battery will not only heat up, but also burn. In this case, there are two solutions. First, buy a charger that fits the charging current with the drone’s battery. For example, the lithium voltage single section is 3.7V nominal voltage, 6 single core is 22.2V nominal voltage, then the charger supports 3.7V to 22.2V lithium battery pack. Second, select the balanced battery charger that can be set. The set-up balance charger is worth the extra price because it allows you to perform more battery management system tasks. For example, check that the battery is charged and discharged as designed and completely discharged before storing it. It allows you to charge the voltage needed on the battery, which greatly improves the life and safety of the drone battery and recharges it. There is also a bug charging condition. In reality, there are also some flier to save time, the battery to charge quickly. Agricultural drone battery have just been used, and the battery temperature is relatively high. At this time, if the battery body is charged at high temperature, easy to damage the internal performance, resulting in life decay too fast. 4. Risks of using with different sizes or old and new batteries The battery should be used together to choose the same model, the same batch, the same cycle life of the battery. The battery needs to be charged or discharged before use. The initial single core voltage needs to be exactly the same. There are differences in characteristics between the batteries. The cores of the same type of electric core in different batches have differences in initial voltage, internal resistance, capacity and so on. The battery’s condition will be basically different after use. If two batteries are charged, first on both batteries, this current is very high and may damage the connector head. As the charging time occurs, the current decreases. When the voltage difference between the two batteries is zero, the battery stops charging the other battery. The entire duration of charging will vary depending on the battery’s capacity difference and pressure difference. However, there is a problem with excessive current charging during this time. Long-term damage to the battery, resulting in battery failure, and even fire and other problems. In the same case, even if the new and old batteries are in the same batch, the same model. They also reduce battery life, even when flying because of different power currents, burning conditions, drone crashes. Mixing of old and new battery packs can also cause the battery to decay too quickly. This will not give full play to the maximum discharge power of the battery. 5. Easy to exist full electricity and high-voltage storage phenomenon Fully charged batteries cannot be fully stored for more than 3 days. If you don’t let the electricity go out for more than a week, some batteries will swell directly. Although, some batteries may not swell for the time being. However, after several full-charge saves, the battery may be immediately scrapped. Therefore, the correct way is to charge after receiving the mission. If there is no mission within 3 days after battery use, charge the single-chip voltage to 3.80 to 3.90V. If there is a good charge after a variety of reasons are not used, but also in the full yin within 3 days to discharge the battery to 3.80 to 3.90V to save. If the battery is not used within three months, charge and discharge the battery once and continue to save. This extends battery life. Battery storage should be stored in a cool environment, long-term storage of batteries, it is best to place in a sealed bag or sealed deflator. The recommended ambient temperature is 10 to 25 degrees Celsius, and dry, non-corrosive gas. 6. Regular lying and maintaining battery For now, these bad problems with agricultural drone battery can be solved. Users should regularly check the main body of the battery, handle, wire, power plug. Observe if the appearance is damaged, deformed, corroded, discolored, skin-breaking, and the plug-to-aircraft is too loose. At the end of each job, wipe the battery surface and power plug with a dry cloth to ensure that there is no pesticide residue to avoid corrosion of the battery. The battery temperature is high after the flight and needs to be recharged by the flight battery temperaturebelow 40 degrees Celsius (the flight battery charge sits at an optimal temperature range of 5 to 40 degrees Celsius). At the end of the job, it is recommended to slow charge the battery. Summer temperatures are relatively high, batteries are best not to bask in the sun. After winter discharge, the battery takes effective insulation measures (e.g. with a incubator) to ensure that the temperature of the battery is maintained above 5 degrees Celsius.

    Manned Drone

    Did you ever dream of flying freely in the air when you were a child? Now, someone has successfully realized his dream of flying. He is Zhao Deli, who succeeded in inventing a drone capable of carrying people. This new type of motorcycle/drone, which looks very much like the airship in the movie, can be lifted vertically by driving these motorcycles while flying, and its speed is amazing. And the Manned drone with Four axis and eight rotor design, and adopts Grepow exclusive Customized battery that with high capacity, high C rate, longer flight time, strong power, safe and stable. Tattu 22000mah 14S 25C battery as the key electric drive to ensure the safety of aircraft in the flight. 100 kg and can reach a speed of 70 MPH. It works the same way as a helicopter, with the ability to rise or fall in place and hover in air, and also has GPS and gyroscope factions. The idea of manned drone is innovative, it meets the needs of many people that avoids the traffic jam at work. And the manned drone/motorcycle is more convenient and faster. Off course, it needs to improvement of technology, such as carrying capacity, safety and other aspects of performance. It will become the future of people’s life needs of the vehicle. Do you like this Manned drone?

  4. We have been using Tattu 16000mAh 4s batteries for two seasons now in the Antarctic. Flying the Alta 6 from a small inflatable boat in the extreme cold and 200mile offshore. These have been super dependable with a relatively linear discharge rate and flight times are amazing and have been very consistent!! Tattu are by far the best batteries we have used so far. ---From Julian Dale's Experience review.

  7. As we know, Xiaomi drone 1080P released on 25th May 2016, and 3rd March 2017 Xiaomi finally announced its 4K version drone. So what’s the difference between Xiaomi Drone 4K version and 1080P version? First of all, let's see comparison chart. For appearance to distinguish them is the golden LOGO and aureate ventilation holes.The 1080P version of Mi Drone uses a color palette of white and orange.The 4K version of Mi Drone has a color palette of white and gold. 1080P version 4K version Quick release props and motors from 4K drone. CPU from 4K, below is 1080P. And the 4K CPU looks much more thick and solid. The Xiaomi drone 4k version is one of the options that I would recommend to just about anyone. You can buy xiaomi 4K drone on
  8. As Drone become more and more popular in rc field, it has been more and more for us to pay attention to. The most important thing is to check the drone physically and know the basics before fly your drone. Drone parts are expensive, so it is necessary to check out all the parts before you head out for a flight. Here are some basics you need to check off before taking off your drone. 1: Weather Conditions Drones is critical to the operating temperatures so that their gears do not freeze and their batteries remain undamaged. Be sure to refer to your owner’s manual for your device’s operating temperature range. Almost all consumer drones should not be flown during the winter due to below zero temperatures. 2: Your Drone Status Checking Also it is important to check your drone for any loose parts or areas of damage. Begin by checking that the unit’s blades are firmly attached and would not fall off the craft during a flight. Also inspect each blade for nicks or cracks. If one is found, it is important to ground your flight and obtain replacement parts. 3: Battery’s Capacity Checking Checking your drone’s battery is fully charged and ready to fly. If you suspect your battery may have an issue, immediately contact your aircraft manufacturer’s support department. Now get a proper battery is good for us, many drone battery now can automatically check the battery capacity, battery status, such as Phantom battery, Tattu Plus smart battery, etc. Before fly, you can know the battery status by the indicator. 4: A Clear Area There are many different shapes and sizes of drone, so you need to ensure the fly room before take-off. Large vast fields are recommended, but that doesn’t mean you can’t take-off from your backyard, permitted it has enough space. 5: Return Home Location Setting Before flying, please ensure that you have a strong GPS signal and note whether your drone has a lock on its current take-off position. This can be set up within the mobile application.From personal drone flight experience, I also recommend programming your drone first to ascend to its maximum altitude before returning home.

  15. Most of the quadcopters are powered by lipo batteries, a low temperature environment will greatly decrease the performance of a lipo battery. When exposed to a temperature below 15°C, the chemically reactive substance in the battery obviously decreases as well as the discharging ability influenced by the increase of its internal resistance, and the voltage drop accelerated when the battery's discharging. There are two risks if the cell drops below 3.0V. 1. The power system for the aircraft cannot provide enough thrust to maintain its flight. 2. The battery will automatically shutdown to avoid over-discharging. These risks are very common to see, however there is still no a perfect way to solve the problem. Intelligent devices like smart phones or tablet computers will also auto shun down when staying in a low temperature. Then we have to talk about the flight theory of the lipo-based quadcopters. For the heavier quadcopter, they need stronger current to provide enough thrust. Battery will draw a continuous high current to boost the quadcopter to a maneuvering flight when flying in a full throttle. In a plateau region, the quadcopter calls for higher motor speed and a higher current of the battery to maintain a regular flight in the thin air and low air pressure. For all the situations mentioned, the battery voltage drop gets even worse because of a low temperature in winter. More seriously, the battery even auto shuts down result in a quadcopter crash because of a low battery voltage. Therefore, Gens ace & Tattu suggested to take these steps for battery usage precaution in winter. 1.Make sure the battery is fully-charged and staying in a high voltage status before you fly with your quadcopter. 2. Preheat your battery over 25°C, which will decrease the internal resistance of the battery. A battery preheater is strongly recommended for preheating your battery. 3. Hovering the quadcopter for about 1 minute after taking off, this will also help the battery to get preheated and decrease the internal resistance. We must pay more attention to a safety flight in winter for a higher risks of quadcopter crash. Getting your quadcopter crash will not only spend you a lot of money for a repair but even it may hurt the people.
