Why Such a Short Time of RC Lipo Battery

The RC lipo battery has a limited life, like as human, cars. Under normal circumstances, RC lipo battery after about 200 times the charge and discharge of storage capacity to the discharge will be significantly decreased, use time is also lower. How to use the 200 times charge-discharge? Or how to extend the battery lifespan? Let's to listen the battery expert's recommend.

At first, charge the highest voltage of 4.20v

It's known to all, 4.20v is always the highest voltage of lipo battery, but with the development of technology and improvement. At present, most of manufacturers of lipo battery can be safe to reach 4.25v, even more of the top technology manufacturers can achieve 4.30v, so 4.30v is the highest voltage at current technology.

Model airplane with lipo battery charger are basic set voltage 4.20v, so use charger of voltage 4.20v to charge the lipo battery is OK, but if you raise the highest voltage to charge (such as 4.35v), they will irreversible damage the lipo battery.

At second, discharge the lowest voltage of 2.75v

Maybe many hobbyists have some questions, why? After research, every RC lipo battery has stage of voltage test from 4.20v to 2.75v. No matter from the battery internal structure theory of data, or from the battery discharge measurement, the lowest voltage is 2.75v.
Remind the important thing to hobbyists,at first tell you the roughly of the battery voltage contrast parameters:

2.75V approximately equal to 0%; 3.56V approximately equal to 5%; 3.70V approximately equal to 10%; 3.75V approximately equal to 20%; 3.85V approximately equal to 50%.
If not do scientific research and the battery with high resolution, the above data can be treated as a standard data. If there couldn't find the same leaves in the world, and also couldn't find two pieces of the same parameters of batteries, only the parameters of similar. So more than the contrast of voltage and power relations we only use symbols to represent "approximately equal to".

From the above battery voltage compare relations you can know, when the battery voltage to 3.56v is only 5% of the electricity, the 5% of the electricity control isn't good, it's easy to reach 0% of the limit value, more than the limit, the battery bilge gas immediately.

At third, within 1c charge current to the RC Lipo battery without injure. 5c charging isn't recommend

Battery charging is a process of converts electrical energy into chemical energy, is a chemical reaction. The chemical reaction has considerable relationship with temperature and pressure. The earliest lithium battery only lithium and manganese substances, the reaction procedure for Li+MnO2=LiMnO2 is REDOX reaction.

Why the cheap RC battery pack has the using lifespan?

According to the experimental data and theoretical prove, within 1c charge current to the battery without injure. More than 2c current will cause the capacity declined slight, and then up to the 5c current, the capacity obvious reduction.
The mainly reason of capacity reduction is the battery internal material generated crystal lead to chemicals. So we use the 1c current to charge is benefits the RC lipo battery.

The application of drone in ecological protection

Due to the unique bird's-eye view, the drone can observe a wider range. The drone can offer you help no matter you are an agency selling real estate or you are a forest patrol.
In fact, drones, a cutting-edge technology, have been applied in ecological preservation areas, which would make the protection works easier. Let us see how it works.

In forest degeneration areas, the traditional plating method needs a large quantity of manual labors, which is time-wasting. In 2015, a new British company designed a drone, which can sow a special seed capsule into the soil. In practice, just like a bullet, the seed capsule would be shot and fixed into the soil. At the same time, the seed will rupture and can be exposed in the sunshine, then it will grow.

That drone can successfully sow ten seeds per minute, and it is estimated that a group of drone can sow 36,000 seeds for maximum every day.

However, the drone can be used before seeding. Scientists can take advantage of drones to make aerial photography towards the forest degeneration areas for the ground mapping. Moreover, the drone is able to supervise the illegal plant-cutting in the forest degeneration areas.

Supervise the habitats

The drones, with light weight and good performance, can shoot the detailed aerial photography, even converted into 3D model. Scientists can quickly identify the change of habitats when they use the drone to shoot systematically such as the periodic shooting for a certain area. The change of habitats can attribute to the the change of density of crown, erosion of river bed, quality and quantity of water, etc.

Drones can make aerial shooting for a large area in very short time. The scientists can analyze the change of the human activity, such as plantation destroy and expansion of the market around the particular habitats through image scaling.

fight against poacher

Drones can use with various tools, and one of them is thermal imaging camera. In some situations, this camera can transfer the video real-time to the researchers. Those two factors make the drones become the effective weapon to attack the poaching. Thermal imaging camera can shoot the human's appearance and shape through the trees and can track the campfire set by the poachers. Tracking poachers by drones is comparatively safe since the poachers often hold the weapons. Knowing the position of poachers contributes to the arrest, and stops the poachers from hiding.

tracking animals

The biologists in ecological preservation areas are using radio to track the displacement distance of animals and their habitat scales and judge whether the animals have entered the prohibited areas (non-preservation areas or human activity areas).

But the radio is regarded as an out-of-date method and time-consuming, because scientists have to go to the regular activity areas of animals in person, track the radio signal on foot and make record. In contrast, the drone can fly following the radio signal and collect the data and image more quickly, so that the scientists can track more animals and acquire more data.

Be against the forest fire

Thermal imaging cameras can also be used in investigating forest fires, avoiding the expansion of fires to cause the serious result. With the help of drones, people can make the quick reaction and control the fire easily.

But the drones can make more contributions to the forest fires. Till now, the firemen have always taken the planes or helicopters to observe the fires. Unfortunately, the firing areas are full of danger, such as the collision of several aircraft in a limited space. The drones can renew the the observation measure and guaranteed the safety of pilots and firemen.

Of course, if the drones are not the only equipment, the drones should cooperate with the aircraft very carefully and precisely.

Drones protect future

Undoubtedly, the drone has changed lots of fields, from estate selling to military activities. Recently, the drone has made contributions to ecological preservation areas and biological field. Now that the ecological protection has not made so much progress, the drone tech would definitely become a popular auxiliary.And also the UAVs flight time is a very popular industry, Gens ace &Tattu lipo battery has a few of reputation in the UAV field, if you interested, you can pay more attention to Gens ace 2s lipo battery and Tattu smart battery.

Battery Life Regarded as a Factor to Influence the Wind Direction of UAV

In recent years, with the rapid development of the UAV industry, A number of well-known enterprises such as Dji and Corbett Aviation emerged on the market and causes continued focus from capital and industry giants. However, the short flight time (general consumer drones only 20 minutes or so) still limit the application and development of the UAV. How to solve the problem of battery with short flight time? What role can IC products play in this area?

Flight time is less than 45 minutes but Charging over 1 hour

With the development of science and technology in recent years the application of UAV has expand from military to civilian areas, and it becomes more and more popular. According to the forecasts from research firm BI Intelligence, the next 10 years UAV will account for the UAV market share of 12%, valued at $ 98 billion. The current market size is 30 billion RMB in the UAV market. with the improvement of our airspace and UAV open regulatory policy, the next 10 years China's civilian UAV growth is expected to exceed 30%.
However, at the same time in the fast start of UAV market , the limited flight time and other constraints have gradually become prominent. Flight time has been a limit in the development of UAV technology. Currently, the UAV battery on market ofthen use lithium battery as the main driving force, and endurance is typically between 20-30 minutes. This is a major short board of the development of UAV, greatly limiting the overall potential of the UAV industry.
According to the reporter's investigation, the UAV on market including Dji and multi-rotor mostly use lithium batteries as an energy source currently. Because lithium batteries with mature technology are easy to purchase. But individual differences, incomplete balanced charge and discharge, and long charging time for high power battery make it more cumbersome to use. The biggest problem is flight time. Lithium battery with the weight of 300 grams theoretically allow UAV with 500 grams weight to flight 17 minutes, even taking into account the technical differences, as well as the body weight and other factors, the flight time of vast majority of UAVs are all within 45 minutes. But the charging time is more than one hour.
Therefore, it is a challenge for all UAV manufacturers must face: how to enhance UAV endurance and allowed them to meet consumer or even industrial market demand.

Power management chip technology plays a important role of UAVs on market

The biggest problem we are facing is the lithium battery of UAVs with short flight time. It is no breakthrough in the material of lithium battery.In that case, there are two ways to solve the problem: some manufacturers began to try new replacement materials for lithium battery ; Adopting technology of power management chip to achieve effective energy management. Prolong flight time of battery to the utmost extent and charge battery fast.

HUS company in Singapore developed the first multiaxial UAV HYCOPTER using hydrogen fuel cell in May 2015. It can fly continuously for four hours with no load, even under full load of 1 kg can still support 150 minutes. Currently, Dji, Corbett aviation and other manufacturers are also making use of hydrogen fuel cells attempt.
However, as the most common materials, lithium battery with solid power, mature technology, and the use of safety are still the most preferred electricity choice for consumer drones. For example, in September 2015, a leader in the field of electric vehicles, Tesla publicly announced a specific application of aerial UAV prototype. With its strength in battery and power management technology, a UAV from Tesla equipped 10000mAh battery. It can fly 60 minutes a single charge, and the charging time is only about 20 minutes.

In this case, the superior power management chip technology has become one of the key factors to affect the success or failure of the UAV market.

The key point is to find a balance charge

So how the current power management chip technology develop in the UAV market? According to reports, battery management chip is a kind of chip to perform condition monitoring, security management and charge management of battery of electronic device. It can control the voltage of charge current , promise the security of battery, and predict accurately on remaining capacity of battery. IC performance of battery management has a great impact on the operation and use of electronic security equipment

Power management chip has very broad applications, and it is widely used in smart phones, laptops, charging treasure, tablet PCs, smart wearable devices and other products. At the same time, as the quantity of electronic products increases using the power management chip to achieve fast charging has been in the leading place on market.

UAV is the most promising market to achieve fast charging. According to reports, from power management chip, there are similar solutions between smart phones and UAVs. However, charging the phone is subjected to the restriction of USB interface and battery. USB interface typically supplies at 5V . Currently, the highest voltage of mobile phone battery is generally 4.2V, and the high voltage of fast charge eventually drop itself to a voltage the phone battery can withstand and then increase the current to achieve fast charge. The Principle of UAV fast charge, although the same with mobile phone, need to increase their voltage or current, but the difference is, the battery may be made up of several lithium cells (such as three cells 3 * 4 = 12V, that is, to charge the battery at 12V). Because the realization of the tandem cell, we need to consider the balance charging problem to prevent the accidents caused by charge imbalance.

As for the future technological development, on one hand, fast charge technology of the mobile phone is trying to find a high voltage (such as 12V) for mobile phone into a high current. On the other, attention need to be paid to the phone adapter and communication protocols to prevent high voltage burning the phone . There are no restrictions in UAVs, and it is the fastest as long as each cell can withstand the maximum voltage and current. Therefore, there is great room for the development of the technology of UAV fast charge in the future.

You had better to know about the RC battery

More and more RC aircraft enthusiasts, but so many enthusiasts do not comprehend the rc car batteries lipo,which then they use the lipo battery is wrong,and even violation operation. That lead to battery swell,even fire. It is sound so terrible. Now I want to tell you some ways to use the battery. Of course,if you think this ways is wrong, welcome to criticism.

1.At the first time use the lipo battery, you should to charge first, and then use when fully charged. Do not use the partially charge,because it effect the battery life.
2. Charge to choose balance charger. Batteries charging with a few pieces, avoid monolithic battery voltage also other difference is too large, affect the service life of the whole.
3. Avoid the battery over discharge, it is recommended that the battery with low pressure alarm device, reasonable control the time of flight, for the plane leave enough spare capacity, To avoid no electricity caused the RC airplane bombed.A is the first killer of battery life!
4. Battery storage method, 3s 1300mah lipo to store the most appropriate voltage of 3.8 V or so, Do not be filled with storage, full of storage is the direct cause of the battery swells,Because the battery has the power, so the deposit after a period of time to conduct a charge and discharge process, voltage back to the store after store, doesn't charge for a long time. Self-discharge will cause low voltage, battery scrap directly.
5. After bombed, to check the battery have any injury or damage and monolithic voltage is stable or not, if the voltage is stable, normal skin without damage, you can use. But be careful, when charging had better pay more attention to observation, avoid the short circuit heating, even smoke explosion!After the bombing of the battery is not use.
6. Do not disassemble battery by yourself, Welding battery easy to cause overheating, don't match batteries welded together, it is easy to cause monolithic voltage use too fast, effect the battery life.
For the bulge of battery has already happened, Do not to frozen, pressure etc to let its recovery, batteries have taken place in the internal chemical reaction, not by external force can recover, more don't prick the battery with a needle, deflated after the battery is completely had zero voltage slowly in place. That is to say, the battery scrap completely.

Some Tips For LiPo Battery Safety

LiPo batteries are generally safer and more environmentally friendly than NiCd and NiMH. LiPo batteries are becoming the most popular high performance RC battery and are used in RC cars, boats, planes, helis, multirotors and more. However, if charged, discharged, stored, maintained, or handled improperly, they can become extremely dangerous. This is a simple guide for safe LiPo battery ownership and use. This guide applies to all RC LiPo batteries including all DJI Smart Batteries used in the Phantom 2 series and Inspire 1. Here we can recommend you Gens Tattu and Ace lipo batteries for you, Gens provides a whole set of battery system for customers in areas of electric cars, electric tools, RC planes, RC race cars, military equipment, solar and wind energy storage, and National Grid. Gens aiming goal is “serve the society with high quality products”.

 Storing and Transporting your battery

If your LiPo batteries are going to sit on the shelf for a while, they are happiest if the cells are at about 3.7 to 3.8 volts each. If you've just finished flying then chances are your batteries will be close to this but if you've charged your packs and then didn't use them, it's vital to have a method handy that will allow you to discharge your packs to this storage level. Some balance chargers have a discharge function but if you're running high capacity (mah) packs they can be slow to complete a discharge cycle. If you rig an alternate method just be sure that it won't discharge the packs too quickly as that can damage your packs making them very unhappy and a true LiPo Ninja can't have unhappy packs.

It's preferable to store your packs in a cool area where they can enjoy a relaxing chilled period of inactivity. Storing batteries in cars, trailers, sheds, etc can expose them to high heat which can degrade the materials in the battery making them not last as long and not hold as much of a charge.

Before putting batteries away after flying be sure to check them for damage as even minor looking dings and dents can cause internal shorting which can lead to a fire. If after putting your stuff away after a day of flying it would be a surprise to find out one of your packs is burning in the basement, no? LiPo fires are hot and intense as well as being difficult to put out. Avoid fires at all costs by understanding your batteries and by maintaining good habits for use, charging, and storage.

LiPo Battery Handling & Storage 

• Keep LiPo battery packs WELL out of reach of children.
• Do not put battery packs in pockets or bags where they can short circuit.
• Do not store or transport batteries where they can come into contact with sharp or metallic objects.
• Do not store your LiPo pack in extreme temperatures below 0C or above 50C.
• Always store your LiPo pack in a safe and non flammable container away from flammable objects. A LiPo Sack or metal / ceramic storage container is best.
• Always store your LiPo?ˉs partially charged. They will maintain their performance levels over time and there's no need to cycle them unless stored for periods longer than 3-6 months. 
• Do not immerse the battery in water or allow the battery to get wet.
• Do not dispose of in fire or heat.

When mailing or shipping LiPo batteries, always ship them at a 30% charged state for safety reasons.When storing batteries for extended periods, store at a half charged state. To dispose of a LiPo battery, discharge it fully then place it in a bucket of salt water for one week. To dispose of, follow your municipal battery disposal guidelines.

Lipo Charging

Charging Lithium Polymer or LiPo batteries have very specific charging requirements and MUST only be changed by specific chargers designed to charge lithium polymer batteries. We recommend only balance charging your lipo batteries. All good quality Lipo battery packs come with 2 leads. The main charge / discharge lead and connector and a balance lead and connector. Using a computerised balance charger to charge your Lipo batteries will ensure that all the cells in the battery pack have the same voltages. The voltage value is critical to the condition (during use) and safety of each cell, which we will cover more in this article.

• Never charge Battery's unattended
• Always use chargers designed specifically for charging LiPo battery's
• Never charge LiPo batteries with chargers meant for NiMh, or NiCd battery's
• Do not charge battery's on or near any flammable materials, this will help ensure that if there is a malfunction it can be contained with the least amount of damage and injury possible.
• Always charge your battery in a fire proof container or LiPo safe sack. Do not charge your battery in your RC vehicle. 
• Always visually inspect your battery before charging and after charging.
• Always allow your battery to cool to its safe ambient temperature before charging after its previous discharge cycle.
• Monitor the resting voltage of your battery before charging, Do not charge any battery that has lower voltage than 3.0Volts in any cell.
• Always select the correct cell count on your charger, please reference the chargers settings to the battery's label.
• Never charge the battery exceeding 2C, C=the thousand value capacity of the battery (5000Mah = 10amp max charge).
• Monitor the battery's voltage after charging to ensure that your charger has not exceeded 4.2V per cell.
• Always double check to ensure that your charge leads from your charger and to your battery are of the correct polarity.

LiPo Balancing

For your multi-celled (2S and higher) LiPo to run at its best and last its longest, the individual cells need to be charged equally. The term for that is balancing.

A charger can't supply the same charge to all three cells. For example, if you have a 3S where the three cells are discharged to 3.1V, 3.3V and 3.7V and you plugged them into a non-balancing charger, the 3.7V cell would hit the maximum 4.2 volts well before the other two. And then it would exceed the maximum as the other cells continued to charge "C" destroying the cell and possibly resulting in a fire.

That's why every LiPo with one or more cells will have a balance plug (sometimes referred to as a balance tap). The charger uses the balance plug to monitor the individual cells while charging.

Conclusion

It is my hope that all RC hobbyists are responsible lipo users. This includes both using and maintaining lipos, as well as disposing of them properly when the time comes. All it takes is fully discharging a lipo to render it inert and safe, and then can be simply tossed in the trash. Being responsible for your lipos is not hard, it just takes some basic knowledge and a little bit of effort. So keep that in mind next time you have a lipo that needs retired.
