At http://www.genstattu.com They are confirming that they are Top Pilot packs, and They are confirming that they are Graphene packs, Which Mean It can Handle More Than 500 cycles(when properly use with care.) so I know we’re already in for a treat with their performance.

I like 12Awg grade wire for some serious amp draws. The Lenght Of Cable is not too short and not too Long. It can be easily useable On 200-240 class quads. It also Comes With Balance connector (protector) which is good to use to save balance lead from props and easily asseable When charging Them. Weight is About 182 (for 1550mah) I honestly use this lipo For race Weight to power ratio is like 180grms of lipo on beast setup.

TESTING

I don’t have ant Testing Equipment But i have other lipos like bonka, turnigy etc To Compare With I Gernally Fly them on a course and checking for battery sag, Internal Resistance,Build Quality.

Build Quality- As the Tattu is Known For good quality lipos they Directly reflects when You feel then In hand.

Checkig Sag & Overall Performance-I Fly Them around 13-15 cycles each last week. during heat i droped cells to 2.9-3.0v.After 1hr when i Reached Home I Charged Them I was Surprised To see no puff . They are True 1550MAh.This means that the 1550mAh genuinely gives you around 1550mAh if you leave around 20% in the pack as you should.They are Cold when They Land.

Internal Resistance-Comparing Them to Other Lipos They Are Very Minimal IR. I got 2-3ohms in Each cell in R-LINE & Got 3-6ohms per cell In Bonka. The Same Charger Was Used to ensure the results were kept fair.

OVERALL THOUGHTS

They are a little heavy Compared to 1500mah Lipos (of course Coz its 1550mah), but provide solid and constant power throughout the pack but the fact the power is still there after 30 seconds Of Serious PunchOuts Thats Why it doesn’t matter. Because of the extra capacity I was expecting them to perform not so good, but I am amazed to say I think they performed better. I had pulled on them in my 2:30 to 3 minute flights.From My First Cycle To Last Cycle They performed same which is incredible.. Now i know the Hype. I Will Definatly Use them In Race..

HAPPY FLYING

How can we lack lipo car battery for carnival in the tracks

It is lucky for most of RC car fans to see various modified vehicles and shows performed by masters of drifting with roaring motors and drifting smoke. Many people think that RC cars are toys, which is absolutely not. RC is the abbreviation of remote control, and RC cars follow the strict restrictions regardless of body size or control effect and have high degree of simulation, which is far from what RC toys can do.

Carnivals in the tracks due to the best RC battery

There are several conventional ratios between RC cars and physical cars, such as 1:10, 1:8 and 1:5. RC cars can be classified into drift cars, racing cars, rally cars, off-road vehicles, desert trucks and monsters etc. They have the dynamical system and suspension system the same with cars, which can complete the acceleration from 0 to 100KM and reach 140KM easily.

Of course, whether drifting or acceleration, instantaneous burst moment must be awesome, or cool view can’t be shown. When it comes to this, we have to mention the power source of the RC cars – lipo carbattery. On the market, high capacity, high rate, powerful battery will be more favored by RC fans, which is because speed is the focus of the competition, so an awesome battery is needed for carnival in the tracks.

Let’s take a better lipo car battery for you:

How to experience the fun of flying FPV for beginners

The FPV just like the F1 racing car in the drone, which uses the first person view to control. In the process of flight, through the specified arches, high-speed turns sideways, all-around flips to control the flight. Then, when beginners to play FPV, how to fly it and what to attention?

1. Flight Security

The FPV hitting obstacles is inevitable with a high-speed flight in the air. So most of FPV have a anti-fall. But we should to pay more attention to the flight safety, avoiding to hurts somebody.

2. Choose Open Place

For the FPV racing, it just like the F1 racing car, there is a corresponding runway. For beginners, the FPV is suitable for flying in an open environment. Indoor or small-scale place is dangerous. And don’ choose place that have many trees,people or other obstacles.
You can search for open site on the website to practice. When your skill have high level, you can set arch to practice operations, and also to plan the special flight routes to increase the difficulty..

3. FPV Battery

The battery is also the key to experience the fun of flying FPV. At present, most of FPV battery flight time is about 10 to 20 minutes. So in order to flight more long time you can prepare more FPV batteries or choose the best lipo battery brand .


For the battery, I recommend the Tattu FPV batteries, they have a strong burst, high capacity and long flight time. At present, a lot of FPV drone pilots are using their batteries,such as 1300mAh lipo,1050mah lipo and 1800mah lipo battery, and they made outstanding achievements. So, the Tattu battery is worth to recommend and trust.

4. FPV image transmission

For beginners, it is very necessary to have a FPV image transmission display device. It is very helpful to determine the flight path, especially the direction control. Visual flight is a kind of training method for masters. So, the video display device is necessary, and the best choice to have high definition VR glasses.

5. An assembly or a set

In the FPV drone, the aircraft wheel base is usually used to distinguish the FPV. In addition to the difference in size, the flexibility, speed control, battery capacity and other aspects are different. When the size of wheelbase is large, the load bearing can also be increased, and the battery ,the beginners, the balanced 250 series which has the stable GPS is more suitable, and it is easier to control, so as not to burst.

FPV is a very interesting type of aerial UAV. With goggle glasses, Have a fun of flying FPV.

About RC car lipo battery

Remote control vehicles popularly known as R/C cars are the types of cars or trucks which are powered by a battery and can be manipulated from a distance using a dedicated transmitter or remote. Readers should take note that the term R/C can also be used to refer to radio controlled vehicles. Several sources of power such as electricity and gas can be used to power remote controlled cars. Due to its numerous advantages, RC car lipo battery is strongly recommended to be used in powering remote controlled vehicles. Gens ace 5000mah lipo battery is a perfect type of power source for the remote controlled cars.

Typical RC car batteries usually get old and become frail within a short span of time. Some batteries which come with the remote controlled cars cannot be depended on upon to power effectively the vehicles bearing in mind the fact that remote controlled cars usually require a decent and lasting source of energy to ensure ultimate performance. Most of the high-end remote-controlled cars are available in the market without batteries. Users of such remote controlled cars should not worry about what type of battery to use in powering their remote-controlled automobiles since Genstattu has all the solutions to their problems.

Lipo batteries are commonly used in remote controlled appliances because of their huge advantages. Also known as lipoly battery, the lipo batteries usually dissipate large amounts of energy needed to power high-end remote control cars. Another advantage of the lipo batteries is that they are charged considerably faster than their NiMh relatives. The weight of the lipo batteries is also much less as compared to the weight of their NiMh counterparts an adaptation which facilitates swiftness of the remote controlled cars. The Gens Ace batteries are available in a variety of voltages and capacities to suit different requirements of different models of remote controlled vehicles.

One of the most common types of lipo battery utilised in powering remote controlled auto motors is the 11.1v 5000mAh lipo. This kind of lipo battery available at Gens Ace is engineered in such a way that it is capable of providing the needed power which facilitates remote controlled cars to attain the top speeds they were designed to achieve. Several other batteries of different capacities, cell counts as well as C rating are available in our online shop. Users of the lipo batteries should take note not to drain a three cell Li-Poly battery past 9.0v. To accomplish a long service life for their sets, clients should consider choosing a higher cut-off voltage lipo battery.

Remote control cars are very pleasant auto motors and can be great fun to the users. However, your experience with the remote controlled cars can be very disappointing if one does not use the correct type of battery to power them. Most of the remote controlled cars are designed to operate at a very high speed and consequently, their batteries should be very robust and up to the task. Gens ace 5000mah lipo batteries are the most suitable type of cells to be used in powering remote controlled cars. Interested clients should visit our online shop Genstattu to get to know the varieties of lipo batteries provided and their relative importance in powering different types of remote controlled cars

How to extend battery life and why use frequently can keep the battery best performance?

If the traditional Ni battery is charged for too long, the liquid inside would crystallize. In the way, to maximize the performance, the full charge and discharge are required. However, for the 2 cell Lipo battery, we can charge it whenever we are convenient.
It is a false about the lifespan of lipo battery that we should replace the lipo battery after charged for 300-500 times.
Instead, the factor influenced the lifespan is the charging cycle, and the times of charging will not directly influence the lifespan.
A charging cycle refers to the period from full power to the completely empty power and then fully charged. That does not mean charging for one time, as the following picture shows.

According to the picture, the battery is charged for 20% after the first time 40%. Then, after consumed some power, it is charged by 30% and 20% separately. In the half of this 20% (at the time of 10%), a charging cycle has been finished. And then, the next cycle begins.
For example, the first day, we charge the battery after consumed half of the power, and the second day, we repeat that process. This is just one charging cycle rather than two. Therefore, a cycle may be finished by several times of charging. Every single charging cycle will reduce the power slightly. However, a superior battery can maintain 80% power after many charging cycles. That is why some lipo battery can use normally after two or three years. Certainly, it is also needed that we replace the lipo battery if the lifespan has ended.

The lifespan of lipo battery is commonly 300-500 charging cycle. We set the Q as the power provided by one-time fully discharging. Ignoring the reduction of every charging cycle, the lipo battery can power 300Q-500Q through its lifespan. Accordingly, if we charge the battery after consuming ? power, the battery could be charged for 600-1000 times. (if we charge the battery after consuming 1/3 power, the battery could be charged for 900-1500 times.) we cannot tell the exact number of charging times if we charge randomly. In a word, the total power 300Q-500Q is constant. Therefore, the lifespan is related to the total charging power rather than the charging times. Besides, the difference between the influence of deep charging and discharging and the influence of light charging and discharging to lipo’s lifespan is similar.
In fact, light charging and light discharging benefit more to the RC lipo battery. Only when the lipo battery is calibrated by the product has the need to charge and discharge battery deeply. Therefore, we can use the lipo battery for convenience and do not have to concern about the lifespan.

If the lipo battery is used above the regulated temperature (over 35 degree centigrade), the power will continuously decrease, which means the flight time would not be so long. If charged under the high temperature, the battery would be further damaged. It is unavoidable that storing under the high temperature will hurt the battery’s quality.

If using below the 4 degree centigrade, you would also find the flight time of the battery has been reduced, and even some original lipo batteries of mobile phones cannot be charged. But, this situation is just temporary. Differ from using in the high temperature, once the temperature gets higher and the molecules inside the battery are heated, the battery would recover to the normal energy.

To maximize the performance of lipo battery, we should use it more often and make the electron flow. If we cannot use the lipo battery frequently, please remember to make a charging cycle and calibrate it (charge and discharge deeply) every month.

The lipo battery characteristics and applications

Due to the good characteristics, the lipo battery is widely applied in mobile phones, cameras, laptops, cordless telephone, remote control, electronic toys and other electronic devices.

Li battery, nickel-cadmium battery and NI-MH battery

The cathode material of Lithium-ion battery is graphite crystal, and the anode material is Lithium superoxide (LiO2). In the charging process, Li-ion moves from anode to cathode and embeds in the graphite layer. In the discharging process, Li-ion separates from the cathode of graphite crystal and moves to anode. Apparently, Lithium is always appeared as Li-ion rather than Lithium metal in both charging and discharging process. Consequently, this kind of battery is called Li-ion battery, Lipo battery in short.
The advantages of Lipo batteries are small volume, huge capacity, light weight, non-pollution, high voltage of single cell, low self-discharging rate, more cycle times, but its price is comparatively high. Nickel – cadmium battery is gradually being replaced because of the low capacity, serious self-discharging and the pollution to the environment. NI-MH battery (nickel-metal hydride battery) is cost-efficient and eco-friendly, but since its single cell voltage is only 1.2V, it has some restrictions in the application.

tattu toppilot
The lipo battery characteristics

1. higher weight-energy rate, volume-energy rate.

2. high voltage. The single cell voltage is 3.6V, which equals to 3 nickel-cadmium battery or NI-MH battery put in series.

3.Keep for long because of the low self-discharging rate. (This is the most obvious advantage)
4. no memory effect. Lipo battery does not have the so-called memory effect as Lithium-cadmium battery, so there is no need to discharge it before charging.

5. Long lifespan. In the common working condition, the cycle times of charging and discharging is more than 500.

6.charging quickly. 0.5 to 1 time of current can be applied to the charging process, and the charging time can be shortened to 1-2 hours.

7. can be used in parallel

8. It is the most advanced “green” battery of the world, because it does not threaten the environment and does not have the heavy metal element like cadmium, lead or mercury.

9. high cost. Compared with other kinds of batteries, the Lipo battery is more expensive.

The internal structure of Lipo battery.

Lipo battery is often divided into cylinder and rectangular.
The internal structure is spiral, which puts a very precise and highly permeable polyethylene film between cathode and anode as a partition. The anode consists of the Li-ion collector made in Lithium and CoO2 and the current collector made in aluminum film. The cathode consists of Li-ion collector made in Carbon sheet materials and current collector made in bronze film. The battery is filled with organic electrolyte solution. Besides, there are safety valve and PTC component protecting the battery in the abnormality or short out.
The voltage of single cell is 3.6V, which is not the infinite capacity. Therefore, it is common to put the single li battery in series or in parallel to meet any demands.

The charging and discharging requirements of Lipo battery

1. The charging of Li battery: according to the structural characteristics, the maximum charging voltage of li battery is 4.2V. Over charging is prohibited as the battery would be damaged if the Li-ion from anode is taken too much. The charging and discharging process are demanding, so we can use the professional constant current, constant voltage charger. When the battery’s voltage reaches 4.2V in the constant current charging mode, the battery would be charged in the constant voltage mode. And when the current lowers the 100 mA, it should be stop charging.
Charging current=0.1-1.5 times of the battery capacity. (e.g. The charging current could be 105-1575Ma for the 1050mAh battery.)
2.The discharging of Lipo battery: due to the internal structure, the li-ion cannot move to anode completely in the discharging process. A part of Li- ion should be kept in cathode to guarantee the Li-ion can embed in the channel freely, or the lifespan would be shortened. To ensure that there is some Li-ion in the graphite layer after discharging, the minimum ultimate discharging voltage should be restricted. In other words, Lipo battery cannot over discharge. The common ultimate discharging voltage is 3.0V/cell, cannot lower than 2.5V/cell. The time of discharging depends on the battery capacity and discharging current. Discharging time(hours)=battery capacity/discharging current. Discharging current of Lipo battery(mA) cannot exceed three times of battery capacity. (e.g.10000mAH battery should charged in the current of 30A, or it will damage.)

There are protecting plates in the internal Lipo battery group, so just control the external charging and discharging current.

The protective circuit of Lipo battery

The protective circuit of two cells consists of the two field-effect tube and dedicated protective manifold block; overcharging control valve and over discharging control valve are in the circuit in series, which is supervised and controlled by the protective IC. When voltage reaches up to 4.2V, the overcharging protective tube stops and charging ends. To avoid mistakes, delayed capacitance is added to external circuit. In the discharging process, when the voltage becomes 2.55V, over discharging control valve stops charging the load. Over-current protection is that stops discharging the load when large current flows across the load, which aims at protecting battery and field-effect tube. Over-current test is to use the on resistance of field-effect tube as the test resistance and supervise the voltage drop, stopping charging when exceed the set value. There is delayed circuit in the circuit to differ the surge current and short-circuit current. That circuit has complete function, reliable performance. It is professional and the manifold block cannot be purchased easily, so the amateurs are hard to fabricate.

Best uav battery packs for multirotor fly Long flight time

Are you looking for UAV battery packs for your multirotor X8 or X4 etc., but still confusing about which brand is the best one and most suitable for multirotor? For fly long time pls read ahead and you will find out the answer.

How to choose UAV battery packs

Yes, let us come back to this topic now. How to choose the best uav battery? Before that, tell me what do you really command. Here are some questions just need to clarify a few things. How long flight time do you need? How much current is flowing in a ciruit and at what voltage for your multirotor? How much carrying capacity do you plan to? After you choose one battery, you can use this calculator formula to calculate your flight time, flight times =(Battery Capacity * Battery Discharge /Average Amp Draw) * 60

For instance, you choose a UAV battery packs 6s 16000mAh, and calculate the average amp to be around 60 amps, make an assumption that 80% of battery capacity will be used, then the flight time is 12.8 minutes (Results vary from brands).

About smart UAV battery packs

What is smart battery? Smart battery management system (BMS) will smartly manage your battery. As every one knows, lithium polymer is delicate accessories and need the user take maintenance. Which brand is recommended? The Tattu smart 6S 22.2V 12000mAh battery packis a great choice for large-sized aerial photography vehicles such as the DJI S800, S1000, Gryphon X8, OnyxStar. This battery packs a ton of power in compact, giving you the flight time needed on your heavy-lift aerial photography rigs.

Drone agriculture:Fixed Wing or Multi-Copter

How to choose a drone agriculture? Fixed Wing or Multi-Copter? Let’s do some simple comparisons fist.

Fixed Wing drone:Ag Eagle

Fixed wing drones like the AgEagle RAPID, and SenseFly eBee Ag are often preferred by farmers because they can spend more time in the air than a multi-rotor platforms like the DJI’s Matrice 100.That said, they are best suited for large, open-field scanning.And also Fixed wing drones often carry more payload than a multi-rotor which means more sensors and so more information can be captured in a single flight.

1
But Fixed wing drones are more expensive too, usually they cost $5,000 to $25,000 or more after being fitted with sensors.(compare with multicopter)

Pros

Endurance : fly as much as 10x longer and cover more geography in a single flight
Payload capacity: can carry more weight
Applications: larger selection of sensors

Cons

Cost: usually more expensive
Ease of Use: not as easy as a multirotor
Size: requires more space for storage and transport

Multi-Copter:DJI Agras MG-1:

Multi-rotor ag drones like DJI’s Matrice 100 are better-suited to precision imaging of small/constrained areas and 3D scanning of fields and objects, due to their maneuverability.
Flight times for quads and other multi-rotors are about 1/2 that of a fixed wing drone.

2
Payloads on many multi-rotors are less than fixed wings, so most only carry one or two sensors. As a result, covering an entire field can take twice as long as with a fixed wing.
Multi-rotor drones are generally cheaper than fixed wings, starting at around $1,500-$3,500 for a professional-grade camera drone with software for agriculture image processing.

The Best of Both Worlds

Rather than opting for one type of drone, some farmers and operators purchase less expensive versions of both.
A fixed wing drone is used for large open spaces where long, unobstructed straight-line passes are possible; and, a small inexpensive multi-rotor is used for spot-checking trouble areas more closely, for quick scouting missions and for handling area a plane cannot fly over.
Lots of farmers today start by buying a ready-to-fly quadcopter like DJI’s new Phantom 4.
After testing the ROI of drone surveying, they may upgrade to more expensive and less time-consuming solutions.
Pros and Cons(Compare to fixed wing):
There are many things that multi-rotor drones can do better, for example, when get into confined spaces,like cross a pedestrian path.they can hover over a specific area, what’s more, they need little space to take off and land.

Pros

Cost: Usually more cheaper.
Applications: really good at aerial photography and hi resolution video.
Easy to use.
Can hover,more agile.

Cons

Endurance: less flight time
Payload capacity: usually less weight
Customer service: little support if you are buying a consumer drone
Occasional bugs, is “fly away”
