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.

Source: TradingView

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.


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


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


  • Needs dedicated charger.
