Tattu 18000mAh Agriculture UAV Intelligent Lipo Battery

Now the UAVs used in many a variety of fields,  the most popular is aerial photography, such  as DJI Phantom, Yuneec, Gopro, Xiaomi... and UAVs have many other usage, such agriculture spraying, farming drone, industry survey...UAVs get more and more useful for us, but they have some disadvantages, I think the most serious is their flight time, because most UAVs are using lipo batteries, also a high quality, high capacity and light weight lipo battery will make your UAV flight longer. And there is a good Lipo battery very good!

Compared the polymer battery with the liquid Lithium-ion battery

Compared with the liquid Lithium-ion battery, Lipo battery adopts the thinner aluminum film and the different production method. The thinner the polymer, the easier the manufacturers produce. The battery whose thickness is less than 0.5mm can be produced in theory. Opposite, the thicker the liquid Lithium battery, the easier the manufacturers produce. It is quite hard to make the battery whose thickness is less than 4mm, which has weakness in the capacity. Therefore, the thinner the batteries, the less cost the polymer production has and the more cost the liquid production has.

For the thick specification, the liquid Lithium battery has complete supply chain and technology, high production efficiency, high rate of finished products and cost advantage of manufacture. From the market, though the battery of 5,6mm in thickness has more capacity than the battery of 3,4mm, the 5,6mm battery has lower price. In theory of polymer, the material cost of 5,6mm battery is similar to that of liquid battery. However, nowadays, the process cost is much more than the liquid one. Therefore, there is some gap to form competition between polymer battery and liquid battery from the specification.
Among the recent polymer Li-ion battery, polymer materials are mainly applied in anode and electrolyte. The anode materials include macromolecule polymer or inorganic compound adopted by normal lithium battery, and the electrolyte can use the solid, colloidal macromolecule electrolyte or the organic electrolyte. The cathode always uses the Lithium metal or Lithium-carbon interlamination compound.
The liquid or colloidal electrolyte puts much weight and cost on the Lipo battery and restricts the flexibility of size. However, there is no extra electrolyte in the Lithium polymer technology, so it is more stable. That is to say., there is unlikely to cause danger if the battery is overcharged, punctured, collided, overused and destroyed in other ways.

The new 5000mah Lipo battery has stronger flexibility to meet the products' demand, since it can become thin in shape (0.8mm for the thinnest one), area normalization and shape normalization. To make battery of any shape and capacity provide the manufacturers with the flexible design and adaptability to optimize the performance. At the same time, the unit energy of lipo battery increases by 50%, and other aspects have improvement like capacity, characteristics of charging and discharging, safety, the range of working temperature, cycle times (more than 500 times) and environmental performance. Gens ace 2s lipo battery has a long lifespan,it is better than others.

Lipo Battery strengths:

1.Ultra-thin
2.Flexible: manufacturers can adjust the volume economically rather than the fixed shape.
3.Light: Polymer electrolyte battery does not use the metal cover as the external package.
4.Safety: the electrolyte is unlikely to leak, so it is more stable.Like as the Tattu lipo battery.

Shortage:

1.Compared with Li-ion battery, the Lipo battery has weakness in energy density and cycle times.
2.High cost

Some Points of Agriculture UAV

Agriculture UAV ,Just as its name implies,is drone used for agriculture.this type of unmanned aircraft consist of flight platform (fixed-wing, single rotor, multi-rotor) composition, GPS flight control, spray unit,etc .The drone can be used for spraying pesticides, seeds, powder ,and etc through the ground remote control unit or GPS flight control unit,
Generally speaking, Agricultrue UAV is a small remote control agricultural spraying aircraft, can load about 10 kg of pesticides, spraying pesticides at low altitude,Its efficiency is several times the conventional artificial.

The Downdraft generate by the rotor will help increase penetration effect of mist flow to corps, while remote control operation greatly improving the safety of pesticide spraying.
But also it can real-time monitor agricultural pests by carrying video devices.
Small drones have the advantages of low operating height, less drift, can hover in the air , no need of special landing airport, downdraft generated by rotor helps to increase penetration of mist flow to corps , long-distance remote control operation, improvement of the safety of spraying operations, and etc.

In addition, electric unmanned drones can save at least 50% of pesticide used, 90% of water by using Spray spray technique, which will largely reduce resource costs.

Compared with the oil engine machines, the electric powered unmanned aerial have the advantags of small size, light weight, lower depreciation rate, Lower operating costs per unit and easy maintenance,and also Gens ace 2s lipo battery is light,long life,it's more converient to use.

Features:

1. Powered with high-efficiency brushless motor ,can be equipped with precision instruments, make spraying more accurate;
2. Requires few on terrain ,can operate without the limit of altitude .
3. Short takeoff time, high efficiency, high attendance;
4. Environmental, no emissions, in line with national requirements of energy saving and green organic agriculture development;
5. Easy to maintain, use low maintenance costs;
6. Small size, light weight, easy to carry;
8. Featured real time image transmission, real-time monitoring functions.
9. The spray device features a self-stabilizing function , ensure that spraying is always perpendicular to the ground.
10. Semi-autonomous takeoff and landing, when switch to attitude mode or GPS attitude mode, you only need to manipulate the throttle stick you can easily operate helicopter to land or take off smoothly.
11. Failsafe, when the helicopter lost remote control signal ,it can hover , wait for the signal to recover.
12.GPS gesture mode (Standard Edition with no such function, can be get through Upgrade) can make accurate positioning and height locking, even in windy weather, hovering accuracy will not be affected.
13. The high-speed centrifugal nozzle design, makes it not only can control the speed of the liquid spray, but also can control the size of droplets, control range vary from 10 to 150 microns.

Safety Precautions:

1. Stay away from the crowds! Safety must be always in the first place!
2. Before operating the aircraft, make sure that the 22.2v lipo battery have enough power.
3. Fly in the rain is strictly prohibited! Water and moisture may enter the transmitter through the antenna, joystick and other gaps and may lead to loss of control.
4. Fly in lightning weather is strictly prohibited. This is very very dangerous!
5. Keep the aircraft in sight.
6. Keep the RC model and electronic equipment away from children!
7. Stay away from the high-voltage wire!
