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

Why my drone simple to crash?

As the drone more into people's lives, the crashing drone inevitably come to be to a scorching topic, since for being truthful, frying a machine is as well uncomplicated,while the worst knowledge a drone pilot can face is crashing or shedding your drone through flight. Plenty of new classmate don't have very good instruction, or lack of corresponding processing experience, they normally crashed of ignorance, the causes are various.the reason may be divided into two broad categories:

Prior to flight:

No calibration of GPS and also the compass;
No number of stars on GPS, weak star flight;
Didn't tighten the screw. Propeller should verify once again;
Didn't verify the electric amount of 22.2v Lipo battery. Many people will put together numerous batteries, at times,but they did not press the button to view if the energy enough once they very first fly;
Unfamiliar with the remote control , do not even know when they accidentally set to Japan's hand.

Throughout flight:

Bump a tree, developing, hit anything at all;

Lack of control skill bring about the disorder direction right after the drone fly over-the-horizon;

With the interference spot in the course of flight;

Ignored the sudden wind or windy weather;

From brake management bring about drone roll fell.
To assist you avoid this predicament, we're going to explain the biggest dangers to you and everything you can do to prevent them.

Know Your Drone Piloting Abilities

The biggest danger for your drone is oneself, in particular should you're a brand new pilot or doing work with unfamiliar products. The odds are if some thing goes incorrect throughout your flight, you triggered the issue!
Start out out lower and slow. We all know the best joys of flying a drone can come from soaring around higher up inside the sky, maybe even capturing some killer video, but you have to learn while flying 15-30 feet off the ground just before taking it any higher. For the duration of a worst-case scenario (heading to get a tree/building, operating from battery, losing handle, etc.) you have to get your drone back to the ground ASAP.
Treat New Equipment being a New Drone. If you include new equipment to your drone (like attaching a new camera on your Phantom), treat your flight as though it's a totally new drone you might want to master. Matters like dealing with and RC Lipo battery life might be impacted and could bring about some poor outcomes in case you treat it as though absolutely nothing has modified.

Steer clear of Obstacles

This goes along with flying inside of your limits, but one of the most typical causes of crashes are attributable to flying your drone into objects like trees and buildings. It's also one of the simplest methods to drop your drone acquiring it caught with the top of the 60 foot tree, or on leading of a building you don't have entry to (plus the owners may well not be so great).

Start off out by flying in an open field, away from any trees, buildings, bodies of water, or roadways. This is actually the safest method to make certain your drone comes dwelling with you.

Weather Can Kill Your Drone

An additional important threat for your drone is weather itself. Thankfully, it's very easy to prevent in case you just place within a little time researching climate reviews ahead of hand.
Check the climate report prior to you fly If there's a chance of rain, conserve your flying for a different day! Superior to get protected than have your drone come crashing to the earth resulting from technical malfunctions from having moist.
Know the wind gusts. Make sure you check out the current wind ailments on the weather app in advance of take-off. Most novice pilots can manage wind speeds of 5-10 MPH with out a lot problem. In case you see wind speeds at 15 MPH or over, you must reconsider flying near any obstacles or with a lot of altitude. You might uncover your drone caught in the wind gust that didn't exist at reduce altitudes, and it could carry your drone away or capsize it.

the different drone between UAV and RC aircraft or toy airplane

Nowadays no matter UAV , rc aircraft,toy airplane,are all called drone by the public , and this make the lines between them becoming more and more blur...... The UAV was first developed after the World War 1 , but it was generally used in military after the World War 2. Recent years , UAV has showed its possibility for commercial and civil use. While DJI becomes more and more popular in UAV area,

the technology of UAV for civil use turn to be more and more mature and common . UAV , rc aircaft and toy airplane can be found in every shopping center. But nowadays no matter UAV , model airplane or toy airplane are all called UAV by the public , and this make the lines between them becoming more and more blur , as a practitioner or a hobbyist can you come out with the different drone between UAV , RC airplane and toy airplane in accurate?

The differences between UAV and rc aircraft

First , let's talk about the differences between UAV and rc aircraft.
Let's start from definition , flight control system , Auto-Control , constituent , purpose and administration to organize the differences between UAV and model airplane , in order to fundamentally distinguish.

The differences of definition

Currently , the definition of rc aircraft is that the model airplane must be in your horizon. People's horizon should under 500 meters. It means that while people standing here and look at the model , this distance can not exceed 500 meters and the relative height can not exceed 120 meters. It is a kind of unmanned air craft that heavier than air , has limited in size and has or no power plant and should fly in horizon. That is what we call model airplane.

UAV is totally different , it is a kind of unmanned air craft that use radio remote control equipment or its own program to control. It can fly without remote , people can control it through computer , ground station or ground circuit. UAV can fly thousands of kilometers away and now it can stay in air for 48 hours that means 2 days , it can fly so far in that situation. UAV can fly for a long distance , that is also a notable feature of it , which model airplane can not do it.

The differences of flight control system

The only difference is that whether has navigation flight system and whether can autonomous flight. Popular to say , UAV use its complicated central flight control system to connect with ground control parameters , in order to control its stance and maneuvering achieve autonomous flight.

Though model airplane is also unmanned , but it need to fly in manipulator's horizon and let manipulator to control its maneuvering and regulate its stance.
That's means UAV flies with its "brain" , the "brain" maybe limited by A.I. , not as smart as human's brain. But model airplane's "brain" is always on the ground , in manipulator's hands.

The differences of Auto-Control

In Auto-Control , UAV can deal with many various situation intelligent , complete the mission as required , confirm the mission after data fusion with the ground station and take the next step as required. While most model airplane's Auto-Control only can achieve auto return after lose control.

The difference of constituent

UAV is more complicated than model airplane in constituent. Rc aircraft is composed by flying platform , power system and the rocker in horizon. It is mainly for ornamental of the public , pursuit of out looking or elegance of flying , do not need high technology.

UAV's system is composed by flying platform , power system , Flight control navigation system , link system , mission system and ground station. It is mainly for accomplish some special missions , pursued the ability to complete the task and high technology. Some upscale model airplanes and some low end UAVs do not have too many differences in flying platform , power system.

The differences of use

UAV is more used to carry out some missions that out of horizon , nowadays is mainly used in military and special civil , its biggest mission radius is thousands of kilometers. It can control itself through airborne navigation flight control system. Through link system upload control order and download task information.

Model airplane usually flies in horizon , its control radius is less than 800 meters , manipulator should staring at the plane , use the remote to control the model , there has none equipment on the airplane. Lots of UAV system have the same ability as model airplane , manipulator can control UAV in horizon.

The differences of Security Management

In our country , rc aircraft is managed by Air Sports Management Center , which belongs to National Sports Commission. Civil UAVs are managed by Civil Aviation Authority and military UAVs are managed by military.

The differences between rc aircraft and toy airplane

The differences of participatory

The differences between model airplane and toy airplane is that toys are "dead" , but models are "alive". The reason for toys are "dead" is that toys usually only use its original accessories and almost do not have any choices , if it is broken , people can only buy original accessories , it is also difficult to find.
But rc aircraft is totally different , for example if my television is broken , I can buy whatever size of TV as I want , because all of them are in common use , if I think the old one do not have enough power , I can change it into a bigger one in common use. After all , if you buy a toy , it will always look the same. If you buy a model , you can do whatever you want on it.

The differences of internal structure

From the internal structure , toy axis's ESC , receiver and flight control system are all combined together , all use coreless motor and also do not have the problem of radiating. The advantage for this integrated board is cheap and small in size , the disadvantage is that if one place is broken , then it should be changed into a new one. But because of the expensive cost of model airplane and the need of diy and radiating , so there do not have many integrated board model (except some miniature model craft) , are generally independent devices connected to each other , such as 2s 7.4v lipo battery, easy to use,and if don't have electricity,just replace a battery at any time.

The differences of environment

Model usually can fit outdoor fly and it can be controlled in bad weather. But toy can only fly with breeze or without wind such as indoor environment.

6 WAYS TO EXTEND DRONE BATTERY LIFE

TIP #1: KNOW EXACTLY HOW AND WHEN TO CHARGE YOUR BATTERY

Charging is the Key to extend the battery's lifespan. For getting the best flight time possible, charge your UAV battery right before you're about to use it. "Freshly" charged batteries usually perform better than ones charged several days beforehand. Besides, when you are not about to fly, charge it only 60% of the way and store it in a safe place instead of fully charge it. And, NEVER OVERCHARGE. If the batteries are charging overly, they may ignite or even explode. It is dangerous and also detrimental to the battery's lifespan.

TIP #2: DON'T ALLOW YOUR BATTERY TO COMPLETELY DRAIN ITSELF

Each time that you do this, you slowly wear down the lifespan of the battery. It is recommended that you fly your quad copter with no less than 3.5V. Once it dips to 3.5V, stop flying and give the battery a rest, then charge it for use next time.

TIP #3: AVOID THE STRONG WIND

When you fly your quadcopter in strong wind, your motors have to produce more thrust to maintain the flight, which requires more power conducted by batteries. Therefore, it is highly recommended to fly in a good weather or low wind.

TIP #4: CHOOSE A CONSERVATIVE FLIGHT MODE

Nearly all RC drones come with various "Flight Modes" that you can switch by simply putting a button. The aggressive mode increases transmitter sensitivity and consume more electricity. Conversely, flying more conservatively consumes the power more slowly with a lower sensitivity. Try to fly conservatively when you are not racing!

TIP #5: LIGHTENING YOUR EQUIPMENT

Since the battery discharges faster while recording and shooting, you can turn on the camera and even remove the camera (if it is detachable) to slow down the pace of discharging. This may be helpful of prolong the battery's lifespan.

TIP #6: BUY EXTRA BATTERIES!

The flyers are now purchasing more batteries, for use or for backup, to maintain a long flight time for their drone. Generally, spare batteries can be accessible easily and can be purchased on sites like:
genstattu.com
These tips can make sense in extending the battery's lifetime, but it is unrealistic to double the flight time. SO, taking good care of the gens ace 2s lipo battery and using it properly.
