Influence to the RC Industry Caused by Cobalt Price Increase

Cobalt price has been dramatically raised since 2017. Due to the intense demand and supply relationship, Cobalt price still seems to increase in the next two years. As the most important raw material in RC batteries. How much cobalt price increase will have a straight?

Cobalt Price Raising Trend

Tight supplies continued to push cobalt prices higher in the week ended Friday January 26. Raises of cobalt begins from early 2017 and this rising trend has been carried onto 2018. As a major part of the Lipo battery material, the increase in Cobalt price is having strong effect on the Lipo battery pricing and related RC fields.

Cobalt increased 2,500 USD/MT or 3.24% to 80,000 on Tuesday January 30 from 80,000 in the previous trading session. Historically, cobalt reached an all time high of 80000 in January of 2018.

Cobalt prices are likely to rise significantly in the next two years as the industry struggles to meet rising demand from batteries used in electric vehicles, BMO Capital Markets said.
Being a major element in Lipo batteries production, cobalt is currently non replaceable. As the raise in cobalt price, final products Lipo battery are foresee to be raised accordingly.

Effects to the RC industry

RC batteries are consumables in day to day RC activities. The raise of cobalt directly affects the cost of RC hobby itself. In order to maintain our high standard of the use of raw materials, Gens ace have to reduce the profit, at the same time also go through only a small percentage of 10% price raise across the product line. There’s possibility of another adjustment to be made including Tattu batteries depending on the cobalt price in the future.

Actions took on some suppliers

Some suppliers choose stay with the current price or event discount on products in order to win the price war. However due to the huge change of the raw material it’s impossible to make a profit. Many will substitute lower quality raw materials for cobalt to cut down the cost. Choosing a reliable brand like Gens ace for your RC batteries is quite important at this moment.

Tips for RC fans

With many uncertain factors, weather or not the price raise of raw material price could bring in a large scale of manufacturer’s price increase, is still remains to be seen. From consumer point of view, timing to stock up your RC consumables can also be a very tricky question.

Totally 60% increase to Cobalt price after year of 2017 and another 30% increase took place in just the first month of 2018. To avoid another round of price increase in the near future, it seems to be a best solution now to plan your consumption and stock up what you need for the next racing season or rest of the year.

New material has been discovered by scientists to place the cobalt to resolve the shortage of raw material issue, such as grapheme, iron etc. Of course, the lab is a long way from the track. Massive production of batteries based on new materials still have long way to go.

For general RC funs, it could be wiser to wait until you actually need to restock despite the increase of battery. In addiction, it also saves you from batteries maintenance while storing in the shelf.

For heavy RC players. Since the amount of batteries consumed. There seems to be less point to wait until you actually need to restock. You don’t know when to expect the next price raise. Best solution will be plan your battery for the coming racing season or even rest of the year.

Conclusion:

Cobalt price will still seems to be in raising trend in the future. There is no sign to show when and where the tread will stop. What is you opinions on the cobalt price raise? Welcome to join in the discussion.

Tattu R-Line 1300mAh 100C HV LiPo Review: Extra Boost for your Racing Drone

When I review niche products like this Tattu R-Line 4s HV LiPo battery, it is very hard to find an exciting introduction. I already rewrote the first sentence three times and still didn’t find something satisfying…

In nutshell, LiHV batteries are like nitro for racing cars. While standard LiPo packs can be charged with up to 4.2V/cell, the Tattu R-Line HV LiPo allows you to charge it up to 4.35V per cell safely. Consequently a standard fully charged 4s LiPo has 16.8V and a HVLi has 17.4V. Furthermore, theoretically, LiHV can store more energy than LiPo per unit of weight.

In addition to the higher voltage, the Tattu 4S1P High Voltage Lipo Battery Pack comes with ultra high discharge rate of 100C.

Tattu R-line 100C, 4S, High Voltage Li-Po battery review

Disclosure: I received this HV LiPo pack as part of a product review collaboration with Gens Ace. Although the battery was offered for free, all opinions in this article remain my own and I was in no way influenced by the partner.

Tattu 1300mAh 100C HV lipo battery first look

As usual for Gens Ace, battery comes well packed with charging plug protector and safety instruction. At first look, no visual difference between the standard 95C and the HV 100C LiPo pack.

Tattu 1300mAh 100C HV lipo battery

Battery pack measures around 75 x 35.5 x 33 mm (L, W, H) and weights 163 grams. Size and weight is comparable to other LIPOs with same capacity.

Core features and technical specs

  • Designed for professional racing drones;
  • Higher max voltage than standard LiPo packs (4.35v/cell instead of 4.2/cell);
  • Better storage capacity than comparable size packs;
  • No memory effect;
  • Minimum of 1300 mAh storage capacity;
  • 4 cells of 3.8v. Total voltage of 15.2V;
  • Ultra high discharge rate of 100C;
  • Max Burst discharge Rate: 200C;
  • JST-XH charging plug;
  • XT60 discharge (drone) plug;
  • Net Weight: 163 grams (±20g);
  • Dimensions: 75 x 35.5 x 33 mm (L, W, H).

You might wonder to over-charge a normal LiPo to higher voltage like this Tattu 100C HV allows. My suggestion would be DON’T even try it! It would dramatically shorten your LiPo’s life or even cause fire.

Tattu 1300mAh 100C HV lipo battery review

If you are using mixed type of LIPOs (normal and HVLi), also keep in mind to always check the charger’s end voltage. It needs to be manually set according to your LIPO battery type. Chargers are unable to detect whether you have plugged in high voltage or regular LiPo.

Tattu High Voltage Li-Po battery review: Test

Prior to my test, I performed a Break-in procedure, which is recommended for new LIPOs. This?consists in 5 gentle charging/discharge cycles.

Recently, I received a QUAD PORT RC charger for review, which is not just compatible with HV LIPOs, but also can charge simultaneously 4 types of battery. I also ordered a thermal probe, which allowed me to monitor the LiHV battery’s temperature during charging/discharging.

Tattu 1300mAh 100C HV lipo battery review charging

As you can see in the comparison table bellow, the HV 100C finished the charging process with higher storing capacity. The end voltage was also higher with 0.6 volt compared to standard LiPo. Both batteries remained?cold (~21 °C) during the charge.

Tattu 1300mAh 100C HV lipo battery review data

For the real world test, I used my FuriBee GT 215 drone, which can be powered from 4s to 6s LIPOs. Due to the poor weather conditions I managed to have only two short test flight (one with each type of LiPo). Frankly, I found only a slight difference between regular and the LiHV. Performance increase was negligible, at least for me. If you really need higher speed, it is smarter to switch from 4s to 5s (of course if your drone accepts it).

Tattu 1300mAh 100C HV lipo battery review test

Those who need advantages of a high voltage LiPo battery, this one can be ordered with 15% off from here (delivery from both, US and EU, is available).

Tattu 1300mAh 100C HV lipo battery review verdict

Pros

  • Higher voltage than regular LiPo;
  • 100C, ultra high discharge rate;
  • More power on same weight.

Cons

  • Needs dedicated charger.

What is in car emergency kit

As anyone who has ever broken down on the interstate, or even worse, on a rural back-road. There are few situations remotely as helpless and frustrating. Virtually all vehicles come with a basic car jack and spare tire, however, there are countless situations where these necessities are exceedingly useless.

There are plenty of tried-and-true tools to have at your disposal when you break down, and even a few lesser-known gadgets and tricks. With these helpful utilities, you’ll be able to stay cool under pressure, even if you are a little overheated under the hood. Here are xxxx essentials to pack in your car’s emergency kit.

#1 Reflectors

One of the most dangerous aspects of being stuck on the side of the highway is the risk of collision with passing vehicles. Placing reflectors at successive distances behind your vehicle will help warn other drivers and create a buffer between your vehicle and oncoming traffic.

#2 First aid kit

If you’re involved in a minor collision, having a first aid kit at your disposal is crucial. Be it a car accident or a misstep on the trail-head, gauze, bandages, antiseptics, and pain relievers are all handy items to have around during an accident.

#3 Power bank with a flashlight

The power bank with a flashlight is one of the most important items in any emergency kit. Whether you’re changing a tire roadside or simply trying to flag down help, a little light can go a long way in an emergency. Power bank give your cellphone more juice power. Tattu 10400mAh power bank is good choice.

#4 Fire extinguisher

When dealing with combustibles such as gasoline, it’s probably a good idea to have a fire extinguisher handy. After a car crash, a small fire can escalate into a much bigger problem in no time.

#5 Ponchos

Breaking down is bad enough, but having to change a tire roadside in the rain is even more frustrating. While a basic poncho probably won’t save your life during an emergency, it will certainly make your life easier if you need to walk a small stretch in the rain to find help.

#6 Stinger USB Emergency Tool

The Stinger USB Emergency Tool is certainly something to have at your disposal when things go awry. After a major accident, car doors and seat belts may be jammed. The Stinger packs a powerful punch to shatter the dashboard or nearest window allowing you to quickly exit the vehicle. The backside of the device incorporates a blade to cut through a malfunctioning seat belt as well.

#7 A Car Jump Starter

When you car battery bad, you can use jump starter to starter your car. Also most of jump starter include jumper cables, that are so great if there are other car nearby to give you a friendly jolt. The Tattu Car Jump Starter is one of the most reliable options on the market.

What is difference between X-Frame and H-Frame?

FPV quadcopter racing becomes more and more popular, most of pilots like to diy FPV drones, but many beginners are hesitant what they choose the FPV frame: H frame or X frame? What is difference between X frame and H frame?

H-Frame

H-frames as the name suggest form extended arms from the body that form a shape of the letter H. The H-frame drones were the first drones and have continued to become popular to many over the years. They boast of very strong but heavy frames, they are capable of carrying maximum lots of FPV gear and running a LiPo battery. They have a relatively wider base guaranteeing them stable rolls.
I would confidently say they are good if you are a starting FPV race due to the capability and durability factors especially the batteries of H-frame drone tend to last longer since their positioning ensures they are not easily damaged.
It also makes a suitable best drone frame for racing as it offers plenty of room for easy build and modifications.

X-Frame

X-frames stand out as the big names in racing and freestyle. Configured in an X shape that characterizes its arms it guarantees stability from the centralized center of gravity.
They comfortably perform stunts, rolls and flips. They are also characterized by a symmetrical pitch and roll axis.
Their battery is however more vulnerable in case of a crush due to its location at the base of the done.
X-frames are the best FPV racing frames due to flexibility and predictability in their handling.
H-frames may stand out for beginners in FPV racing but X-frames are rated the best drone frame for racing.
Other popular frames include the v-tail, hybrid X and stretched X frames that are modified for different capabilities and performances. A disadvantage of the unpopular racing drones is that they require custom motors and some parts. That could be a real hustle when you require replacements and spares.

The different frame you need to choose the different battery. For H frame, you’d better to choose long size batteries, such as Tattu 450mAh 2S or 3S or 4S 75C lipo batteries, they all fit H frame perfectly. For X frame, I recommend Tattu 1300mAh or 1550mAh 4s 95c square lipo batteries.

Which battery for Mini FPV Drone: 2S or 3S?

Last week I received from Gens Ace two Li-Po batteries for review. The Tattu 2s 800 mAh and Tattu 3s 450 mAh. Firstly, I thought about making an individually test of each battery, but latter I found it more helpful to make a side by side comparison of them.

Both Li-Po batteries are suitable for micro class FPV drones like the Blade Torrent 110 and KingKong ET series. Weighing about the same (~42 grams), I’m curious to find out which one will perform better (top speed vs flight time).

For my tests I will use the KingKong ET125 drone, which weights about 120 grams and it is equipped with 4-in-1, 10 Amps ESC (2-3s rated) and?7500 KV brush-less motors. Roughly, the number before “KV”; represents RPM/Volt (under no load!), so higher battery voltage means more RPM, respectively higher speed.

2s-800mah-vs-3s-450mah

Which battery is best for micro racing drones, 2s or 3s one?

Disclosure: I received these two LIPOs as part of a product review collaboration with Gens Tattu. Although the batteries were offered for free, all opinions in this article remain my own and I was in no way influenced by the partner.

Both batteries came well packaged and, as I requested, with JST discharge plug. While both LIPOs weights about 42 grams, they have a bit different form factor. As usual for Tattu batteries, they came half charged, about 3.82 V/cell.

Tattu-2s-800mah-review

Tattu 2s 800 mAh LiPo specs

  • Number of cells: 2 (2s);
  • Voltage: 7.4 V (3.7/cell);
  • Capacity: 800 mAh;
  • Max Continuous Discharge: 45C (36A);
  • Discharge Plug (drone side): JST-SYP-2P;
  • Max Burst Discharge: 90C (72A);
  • Dimensions: 51.6 x 25.6 x 21 mm;
  • Weight: 42 grams.

Tattu-2s-800mah-review-vs-2s-GaonEng-550mah

As the stock battery of the KingKong ET125 has only 550mAh, I’m expecting at least 1 minute bonus of flight time for the extra 250mAh. Weight difference between 550mAh and 800mAh is about 7 grams only.

Tattu-2s-450mah-review

Tattu 3s 450 mAh LiPo specs

  • Number of cells: 3 (3s);
  • Voltage: 11.1 V (3.7/cell);
  • Capacity: 450 mAh;
  • Max Continuous Discharge: 45C (20.25A);
  • Discharge Plug (drone side): JST-SYP-2P;
  • Max Burst Discharge: 90C (40.5A);
  • Dimensions: 54 x 29 x 13 mm;
  • Weight: 41 grams.

Tattu 2s 800 mAh vs Tattu 3s 450 mAh

First off all, powering your drone with higher voltage batteries (like 3s instead of 2s) can produce permanent failure of electric parts. My suggestion is to check the “s” ratting of each individual component. For example, the motors and ESCs could be rated for 3s, but the VTX only for 2s.

2s-800mah-vs-3s-450mah-review-testing-tools

After five charging/discharging cycles, I fully charged the batteries at 1 Amp. As you can see in the comparison table bellow, both LIPOs ended well balanced.

2S vs 3S

Real world test

Next day, with confidence I went out to do some real world test. Firstly, I loaded the 2s LiPo into the KingKong ET125. As you can see in the video bellow, due the strong wind gusts, my flight was pretty erratic, so the results are not too relevant. I need to repeat it in more calm day.

Although, KingKong clearly says that is risky to use 3S LiPo batteries with the ET125, it worked very well. I noticed some improvements, but you need to be a damn good pilot to take advantage of the extra speed provided by the Tattu 3S 450 mAh. IMHO, 7500 KV motors are just fine with 2s batteries, especially with a light weight frame.

Tattu’s “Less is more” aka “Less weight, more flight time” slogan, proved to be pretty fair. While their 2s 800mAh LiPo has ~19.05 mAh/gram storing capacity, the 550 mAh Gaoneng LiPo has only ~15.71 mAh/gram. Compared to stock battery I got more than 1 minute extra flight time.

Tattu-2s-vs-3s-review-verdict

Final words

Whether you are looking for extra power for outdoor racing and freestyle or extended flight time for indoor practice Gens Ace Tattu has the proper battery for your micro FPV drone (Blade Torrent 110 / KingKong ET125). You can find the 2s 800 mAh for $9.99 and the 3s 450 mAh for $9.89. Free shipping to US is available for orders over $49.

How to choose the best portable jump starter

Although many people think buying a jump starter isn’t a big deal, the reality is quite different. There are some factors you need to pay attention to before buying a portable jump starter so that you can avoid any unpleasant surprises. Buying a portable battery isn’t the same as purchasing a bottle of milk; there are a ton of variables and important elements included in the equation. Here are some of the things you should pay attention to before opting for a particular model.

The power

The most important thing you need to look for is the sheer power of the unit. Manufacturers usually include “cranking” and “peak” power values.

Peak amps refer to the highest current value the starter can burst out. For example, a product with 1000 amps of peak power will deliver a thousand amps in the initial burst. However, the value drops significantly with each try. As the current decays with each attempt, it loses consistency and starts using what is known as the cranking power.

As you might assume, the cranking power refers to the stable current which can be delivered if extended cranking of the engine is required. Therefore, the cranking power is usually the more accurate representative of a particular model’s capabilities.

Safety Protection

As with any other product, the safety is one of the important factors to look for. However, because you’re dealing with electricity, make sure that you opt for the safest model. The things you should pay attention to are:

Short circuit protection
Over-current protection
Overload protection
Over-voltage protection
Overcharge protection

As you can see, every feature has an “over” prefix. It means that these units are easy to overuse if they lack protection. However, the products that have these preventive mechanisms can be left unattended without them being dangerous for the environment, and most importantly – your car’s battery.

Auxiliary features

Many units have some additional features such as an air compressor or a flashlight. If you want a 2-in-1 or even 3-in-1 unit, pay close attention to these additions. People who are often on the road usually need both illumination and an air compressor for deflated tires. You can’t expect a professional service out of these additional options, but they are still enough to act as a first aid. Also, if you’re looking for multiple charging ports for smart phones, tablets, and more, it’s a good idea to check whether the unit you’ve chosen can charge other devices.
