The 4 best mini FPV quadcopters

1. Eachine QX90

The QX90 is a bind and fly quadcopter, is uses a F3 based flight controller, and has an all in one FPV camera and transmitter. Included with the QX90 is one of 3 receivers, compatible with either FRsky, Spektrum, and FlySky (frsky receiver is only compatible with international firmware and not the EU LBT firmware). Driving this quad are some 8.5x20mm motors which produce impressive power making this quad powerful enough to fly outdoors in the wind! The kit also includes two batteries which is great to get more flying done per session. The frame itself is made from a single piece of carbon fiber so the frame itself is very strong, however the main weakness is the FPV antenna which takes most of the abuse when you crash upside down. However there is an optional FPV antenna protector for it that you can buy. At around £60 / $69.99 the QX90 offers alot of fun for indoor and even outdoor FPV flying. This is currently my favorite goto micro FPV quadcopter.

1 x 5.8G Receiver (Optoinal, need to be purchased separately)

3. Fire 104

If you are looking for something a little bigger and only use spektrum R/C gear, then the fire 104 is a great option. Because the frame is abit bigger it means that the FPV gear is better protected (and it looks abit cooler). Also you can upgrade the motors to use bigger props if you need more power. However despite the bigger size, the weight of the Fire 104 is still very low at just 37g (without battery). Powering this quad is the Micro Scisky 32bits Brushed Flight Control, while old is still fully capable. It uses an older F1 chip (which is pleanty good enough for micro quadcopters), and the best thing is that it has a built in Spektrum DSM2 receiver, which is why the fire 104 is so light. The only downside is that the FPV transmitter is only 16CH and it only uses a linear antenna which is not quite as good as the circular polarized antennas on the QX90 and QX70. But the camera does have a higher TVL resolution, but with a cheap antenna this will not be very noticeable, especially when you start to fly further away so that is something you will want to upgrade, although it will require some soldering.

At present, lipo battery becomes the mainstream of model airplane batteries. In everyday usage, we probably need to use three steps (recharge, discharge and maintaining). Today, I will tell everybody the right way of using the RC lipo battery from three aspects.

Recharge

When you have a lipo battery, you are in no hurry to recharge, but read the battery specification carefully first. Recharge current, voltage and temperature can not be greater than the standard of the specification. What could happen if they are higher than the standard.
1.Using batteries higher than recommended current may cause problems of the battery discharge performance, mechanical property and the safety performance, and may cause heating and leakage, can greatly reduce the battery life.
2. Recharge voltage higher than recommended voltage may cause cell overcharged, usually caused by using in wrong charge way. (Like direct current charge)
3.The recharge temperature here is not the temperature caused by recharging but the environment temperature during the process of recharging. When you find the surface temperature anomalies, you should immediately end the charging.

Discharge

1.Discharge current

Discharge current should not exceed the maximum discharge current specified by the battery. (Formula is "the number of milliampere divided by a thousand and then times the number C" equals the maximum discharge current).

2.Discharge temperature

The battery must be discharged at the range of temperature specified by specification. When the surface temperature exceeds 60 degrees, should stop using, until the battery cool down to the room temperature.

3.Over discharge

Over discharge can cause fatal effect on the battery, so it is best not to make monomer battery voltage lower than 3.7 volts.

Battery storage

Battery should be stored in a cool environment. When you store battery for a long time (more than three months), suggest you put battery in the temperature of 10 to 25 degrees and low temperature, non-corrosive gas. The process of long-term storage, charging and discharging once every three months to keep the battery active, and ensure voltage in the range of 3.8 volts.
Finally, if you don't mean to use a battery in the short term, be sure to remember that do not charge it fully before you keep it. This is to prevent the battery bulge in the process of preservation. The best maintaining method is storage. The voltage is monomer 3.8 volts

Scary disconnect experiece of players when they are playing their drones

Scariest experience to data, thought I had lost the bird.  Had it about 3000' away and coming back my way when everything suddenly disconnects.  Cannot use any features of the DJI app on my iPad air that has never given me problems.(I used a DJI drone with 2200mAh lipo battery)  I've had some tense moments in the past, so I know enought not to panic and to think things through.  I press and hold RTH button on the remote.  Nothing.  No blinking white light.   I'm afraid to close the app.  Should be noted that I'm not on wifi and there is no cached map.  I do see the birds heading in the lower right corner of the screen.  It seems to be moving.  After the initial disconnect I made sure not to move the bird.  I think I should be still pointed towards home.  I can hear nothing, I'm all alone on a hillside overlooking a medium sized lake.  No noise.  I push the stick forward to hopefully move the bird in my direction.  I hear a very, very faint buzzing.  Its getting louder! Yes!  I finally spot it and bring it to me for an immediete manual landing.  App never reconnected.  I was happy to have it backed and not in the mood to troubleshoot at this locale.  I know I need to update firmware but thats been pending for months with no issues.  WTH.  
I thought for sure the bird was gone.  Was shocked to get it back.  Have no idea what went wrong!  That's the hardest part.

I had a similar experience, I had my drone out over 2 miles when my app crashed. I flipped the S2 switch a couple of times, I heard the beeping sound, and then it quit. I flipped it again, and it started beeping again. I eventually got the Litchi app going again, and saw that my bird was on its way back. I test my RTH every once in a while by just shutting everything off, waiting a few secs and she just starts to fly back. I wonder if you had just shut your TX off if it would have just come back? Are all of your settings right? Is it set to hover instead of RTH? After viewing the footage, when the app crashed, I see myself stopping the forward motion and activating the RTH. Why the beeping stopped I have no idea, it just kept coming home. 

How to choose RC lipo battery?

With the development of participation in playing aeromodelling, hobbyist has paid more and more attention on the selection of the RC lipo battery. For the selection of the RC lipo battery, it carries on the explanation mainly from two aspects of battery's voltage and capacity:

1. Voltage of battery

Its voltage should be the same or a bit higher than the voltage of electric motor.

2. Capacity of battery

Unit of the battery capacity is AH, and there is the larger capacity and the larger size under the same voltage. For example, the electric motor has the working current of 10A and the voltage of 12V, which is 10A*12V= 120W. If equipped with the 12V/10AH batteries, the electric motor can work for an hour. If the rated working current of the 120W/12V DC motor is about 10A, its battery capacity is 40Wh when it works as the maximum power of 120W for 20 minutes, and the capacity required for the battery pack is about 12V4Ah, and the equipped lithium battery is power-type battery.

Structure of lithium battery

Usually, lithium batteries have two common types of shape, including cylinder shape and square shape. It is used the helical coiling structure as the internal of battery, and made intervals between the positive and negative electrodes by a kind of polyethylene film isolation material with high intricacy and strong permeability. The positive electrode is the current collector composed of lithium cobalt oxide and aluminum foil, and the negative electrode is the current collector composed of graphitized carbon material and copper foil. Battery is filled with organic electrolyte solution, and installed with safety valve and PTC components, in order to protect the battery from damage in abnormal conditions and when the output is short-circuited.

Why is lithium battery so popular?

1. High voltage and light weight features of lithium battery

The average voltage of a single battery can reach 3.7V or 3.2V. If customer requires the battery with the qualified voltage, lithium battery is the best choice as it can be composed of a lithium battery pack easily and provide convenient and efficient access to improve the voltage of lithium battery.

2. Compared with other battery, lithium battery has higher capacity and density

Lipo battery has high energy storage density, at present, density of the common used battery can reach 450-620Wh/kg, which is 5-7 times higher than the lead-acid battery. In addition, pollution is one of the most important problems considered when people prefer to use lithium battery.

3. Large capacity and long life

The weight of a single lithium battery is about 5-6 times of the lead-acid battery. Although there are less differences in weight between the lithium battery and polymer lithium battery, people prefer to choose the lithium battery as its capacity and life.

The service life of a single lithium battery can be above 6 years and even 9 years if nothing goes wrong. The normal quantity of use is more than 1000 times, if there are no accidents, it can be used beyond 1500 times.

4. Low self-discharge and no memory effect

Lithium battery is equipped with protection plate during the production, which can make the lithium battery have an effect of over-charge and discharge. As lithium batteries have high power tolerance, lithium batteries used for electric vehicle can produce high-performance charge and discharge of 15-30C for the high-strength acceleration performance in starting of the electric vehicle.

Accounding this list, both of them are simliar in general, but DJI Phantom 4’s Max descent speed and mas service ceiling above sea leavel are batter than Xiaomi 4K,  From another way, we can see DJI Phantom 4 used 5350mah 4s lipo battery, and Xiaomi is 5000mah 3s lipo battery,too.

Maybe DJI Phantom 4 is batter than Xiaomi 4K, but on another way, xiaomi 4K’s price is lower than DJI Phantom 4, and Xiaomi is a newbie in Drones, it has a lot of loyal customers and  Xiaomi will have a great development. Xiaomi’s main markert is in China, but DJI is in the world. So I believe Xiaomi drones will get a huge market in China.

The best mini quad lipo batteries:Tattu 4s lipo battery

For most people,you may don't know who is Tattu, but if you had heard Gens Ace, you will know who is  Tattu. Tattu is the sister company of Gens Ace, produce high quality lipos for not only for our application of mini quads but also for large hover ships used for Aerial Photography.

Now I will tell you the Tattu 4s lipo battery, many mini quad lovers called it the best mini quad lipo battery. Gens Tattu is a Professional Battery manufacturers, and their batteries are for drones, cars and quads. Tattu 4s lipo batteries have many types, capacity are 450mah-22000mah, high Discharge rate. For most quad lovers, they like Tattu 1300mah 4s 75c lipo battery. These batteries are available in a wider range of capacities than most brands and cell counts, from 3s to 6s (for those of you who are crazy), and 1000 to 2200mAh. Most people think that these batteries perform well, especially the 75C rated packs. 

Tattu 1800mAh 75C 4S RC lipo battery Testing

I was sent one of the new Tattu 1800mah 75C 4S batteries to do a bit of testing. I've been flying it for a week or so and I have spent some time gathering data. Here is what I've found so far.
To give a bit of background, I am a multirotor pilot, and am primarily interested in miniquads. That being said the testing I've done applies universally. These high C rated batteries are useful beyond the bounds of multirotors into the world of 3D flying, and high performance aircraft.

Physical Characteristics

As with the Gens ace 2200mah I reviewed last month, my first impressions of this RC lipo battery are very positive. Gens ace/Tattu seem to use the same build techniques in both their lower discharge and higher discharge batteries. It has the same aluminum support that covers the battery and adds additional protection to the top and bottom of the battery. After a bit more research I have found that this actually provides compression during high discharge and according to research can significantly extend the life of the battery. Again, where the high current lines enter the battery casing they are re-enforced with additional heat shrink. The balance leads also come out the opposite side of the casing rather than the same side as the high current lines. In addition this battery has a plastic cover that extends over the balance lead cables, preventing stress on the cables when plugging and unplugging the balance cable. I will point out that on some chargers this can prevent the balance leads from fitting properly. Unlike the 2200mah, this battery came with XT60 connectors, which means no soldering for me. Battery dimensions actually exactly the same as the 2200mah 2S battery, and are accurate to the product description on the sellers website. The wight is just over 200g and the physical size is 105mm x 35mm x 25.4mm. Because of the aluminum plates the size is very consistent.

Balancer Connector Type: JST-XHR

Features:

1. Stable automatic stacking technology enables single cell capacities of 1800mAh.
2. The most strict single cell capacity, voltage, resistance, discharge curve matching process.
3. Superior Japan and Korea Lithium Polymer raw materials.
Tattu batteries provide high quality, reliable power for LRC Freestyle V1(270-296), CX Pro Quadcopter(228), ortex, Super Mini H Quad Power Train, drone and FPV etc.

Conclusions

My initial impressions of these batteries both in build quality and performance are very positive. Because of the very high C rating, it is hard to get an accurate picture of whether or not this battery can full fill a 75C (135A) current load, but given very few people have a setup that can draw that type of constant load, that's not something we can easily gauge. Since I haven't found a reliable method for testing internal resistance It's hard to get an objective measurement of true C rating. I will post an update as soon as I can test these on a more reliable tester. I can say up to 65A loads this battery performs excellently. I was also very impressed with how well it recovered from first time abuse.
The battery provides both solid performance and the extras in the build such as the reinforced cables and aluminum compression plates add up to a very nice battery. For those interested, the battery is available here:

Knowing the lithium battery safety knowledge can save your life at a critical time

Jonathan Strobel, a resident of Palm Beach County, Florida, alleges in the suit that his Note7 was in his right pocket on Sept. 9 when it exploded, causing "severe burns" to his leg, leaving him "in shock and extreme pain due to his injuries". Nearly a million Note7 smartphones were sold in the United States. The recall applies only to Samsung Galaxy Note7 phones sold before Sept. 15, 2016. Samsung has received 92 reports of the batteries overheating in the U.S, including 26 reports of burns and 55 reports of property damage, including fires in cars and a garage. Three Australian airlines have banned passengers from using or charging Samsung Electronics' Galaxy Note 7 smartphones during flights due to concerns over the phone's fire-prone batteries.

 Samsung Note7 mobile phone batteries like most cell phone batteries are lithium batteries, lithium batteries are more and more widely used in our daily-life, such as our unmanned aerial vehicle batteries are lithium batteries, so learning how to use and maintenance the unmanned lithium batteries is very important.

Why did the lithium battery explosion?

Lithium battery are better than lead-acid batteries, nickel-cadmium batteries, nickel hydride batteries in performance, and it is better than fuel cells in discharge times. But the safety of lithium batteries still needs to be improved. The biggest hazard of lithium batteries are lithium cobalt oxide lithium batteries in case of overcharge lithium anode formed in Dendrite and pierces the diaphragm, forming internal short circuit. External short circuits, internal short circuit will yield hundreds of amperes of current, resulting in a battery explosion is overheated.

How to use lithium batteries?

1.The charge voltage should not exceed specified limited voltage (each battery chip is 4.2 volts), 4.25 volts is the highest limitation of each charge voltage. Charge current should not be too large (like the TATTU brand charger of 1500mAh 3s battery should be set at 1.5 amperes to 2.5 amperes to charge)
2.Connect battery positive and negative electrodes correctly. If the anode and cathode of battery swap the cell's poles over will not accept a charge. Reverse charge will make battery damage, cause heating, explosion, leaking and burn.
3.Over discharge will make battery damage. When the battery discharges, monomer battery voltage should not be less than 3.6 volts (When single cell is 3.8 volts, the plane should almost begin to descend.)
4.The battery should be kept in a cool environment. When storing the battery for a long time (over 3 weeks), suggested to put in the environment that temperature keeps at 10 to 25 degree Celsius, low temperature and non-corrosive gas. Battery needs to charge and discharge once three months to keep battery activity, and ensure every chip voltage in the range of 3.7 to 3.9 volts.
5.A good battery should have a good charger. Don't use no-name charger.

6.FPV must choose the branded batteries, don't use unknow batteries. Single cell voltage has big difference.

The safety of lithium batteries is not a peripheral issue, it is based on the material nature of technology issues. Battery factory safety testing must also be stricter. The source of Samsung Note 7 battery issue hould be battery manufacturing issues. For most drone lovers, how to Choose a drone battery? You should choose a trusted brand, such as Tattu drone battery, Tattu battery is more focused on Drones/Multirotors/UAV battery pack and designed with high energy density and high discharge rate cells. It has highly reputation in the market with its stable performance. Tattu is committed to supply the safe, stable as well as long cycle life battery for UAV. With each team member takes advantage of individual superiority and take part in the more discussion, we can always keep continuous progress. Except for the universal products, we also devoted ourselves to customize as per your need. Now more and more drone lovers choose Tattu for their FPV batteries, UAV batteries and RC car batteries, because tattu batteries are very useful, safe.
