Grepow High Discharge Battery for Hyperloop

The 2019 Hyperloop Super High Speed Rail Race officially began in April. For Super High Iron Powder, this is a passionate summer!

Super High Speed Rail The Hyperloop is a pipeline-based sub-supersonic transport system super-loop train, initiated by Tesla’s founder Elon Musk. The Hyperloop train is mainly used in a vacuum-like pipeline. The high-rate battery is used to project the train like a bullet, and then the battery is gradually accelerated to a fixed speed, which is estimated to reach 1120kg/h in the future. The battery configuration is also like Tesla, where many small battery packs are placed to form part of the power system (theoretically solar powered).

In the past year, the team from the Netherlands used the high-rate battery provided by GREPOW as the special battery for the competition, and achieved the second place. Now that Hyperloop is launching in the new season, the Dutch team also said that the new season will continue to cooperate fully with GREPOW. With the GREPOW high-powered battery, we still provide them with upgraded batteries, and look forward to this time.

Wearable Battery Is Used In Children’s Smart Shoes

In addition to traditional shoe enterprises, companies in the field of smart shoes, such as Nike, Adi, Li Ning. There are also startups and Internet giants such as Tencent, Baidu, and Xiaomi. It’s an eye-opening market for companies to compete in, and wearable battery will have a place in it.

Children's smart shoes, to build an all-round protection network that protects children's safety and health. Dynamically push the child’s real-time location to jointly monitor the child’s safety and health.

Baidu, 361 — children positioning shoes

In 2015, 361 and Baidu launched four smart children’s shoe products, with the main function of anti-loss. Intelligent children’s shoes introduced Baidu Hawkeye technology, with Baidu map LBS platform open service, with positioning monitoring function, Baidu Hawkeye’s WIFI positioning function fundamentally solves the problem that other children’s anti-lost products cannot be located indoors, sweeping away blind spots. When the child inadvertently leaves the scope of supervision, the first time will be reminded.

This wearable battery uses wireless charging technology. The wearable battery can be charged simply by placing the shoe on a specific charging pad.

In addition, 361 smart children’s shoes will also combine Baidu trajectory monitoring with Baidu’s big data, which can monitor the child's physical condition at any time, and upload the data to Baidu Health Cloud daily, according to the scientific plan of the Million Children's Health Database in Health Cloud. The child is tailored to the most professional health guidance.

Li Ning, Tencent – QQ IOT children's smart positioning shoes

In 2016, Li Ning teamed up with Tencent QQ IOT to launch a children's smart running shoe. The built-in Bluetooth and chip are sealed inside the sole and can be bound to the parent’s mobile QQ before use. By locating the location of the mobile phone QQ user and indirectly obtaining the approximate location of the lost child, the child is found lost and the child is retrieved.

The biggest highlight of this product is that its wearable battery does not need to be charged for half a year, and it can maintain the duration of more than half a year under the premise of achieving the positioning function.

Its built-in has a large number of QQ user bases, using low-power Bluetooth so that the shoes will broadcast a unique Bluetooth signal to the surrounding. In the mobile phone QQ, users who have opened the “Join the search for lost children project” and turned on the Bluetooth option have felt these signals when approaching these smart shoes.

Looking forward to the future

In view of the fact that the traditional footwear industry is already saturated, “transformation and upgradin” has become the keyword for the development of the industry. The market for the wearable battery is also evolving.

Other wearable battery requirements, including battery life, capacity, etc., can be met. The wearable battery produced by Grepow have been applied to smart shoes produced by Fortune 500 companies!

It is believed that with the continuous accumulation of market technology and the completion of the ecological layout, more smart products with innovative and technological charm will emerge in the near future, which will become the fuse of the next round of enterprise transformation.

Tattu FunFly LiPo review: Perfect for daily practice

GensTattu recently launched a new product line, called “FunFly”. Unlike the “R-Line”, it is available only in 4S version and with two capacities. Both, FunFly 1300mAh and FunFly 1550mAh are 100C rated. In the past, we already reviewed couple of Tattu LiPos, including the R-Line HV 1550mAh 100C and now it’s time to have a closer look on the new Fun Fly series.

GensAce claims that their new Tattu Funfly series was specifically designed for daily training and freestyle, which requires medium performance. In order to allow long service time (many charging cycles) it has standard LiPo cells (~3.7V) not high voltage ones (~3.85V) ones.

Tattu FunFly features and specs:

– Available in 1300mAh and 1550mAh versions;
– Designed for daily training and freestyle;
– 4 cells of 3.7v. Total voltage of 14.8V;
– 100C discharge rate;
– JST-XH charging plug;
– XT60 discharge (drone) plug.


Tattu FunFly batteries review:

Like usually, GensAce did a great job regarding packaging. In order to avoid any damages that can occur during shipping, the batteries came in a large box with lots of foam peanuts.

Both LIPOs (1300 and 1550mAh) come in the same type and sized box. Along the battery, a safety instruction is included as well. They arrived half charged (3.81v/cell – optimal voltage for long time storage).


While the FunFly 1300mAh 4s 100C measures around 73 x 35 x 28 mm (L, W, H) and weights 153 grams, the FunFly 1550mAh 4s 100C measures around 72 x 35 x 36 mm (L, W, H) and weights 178 grams. BTW, the price difference between them is only 1 dollar.

Tattu FunFly vs Tattu R-Line

Being a bit confused whats the sens of a new series, when the R-Line does such a great job, I contacted the manufacturer in order to find more insights about their Fun Fly LIPOs. Firstly, I got this feedback “Our Funfly Batteries are mainly for daily practice and for those who fly for fun. Different recipes with Tattu R-lines” Asking again for more details “Sorry, but I really could not explain more. The FunFly batteries comes out for the pilots who fly for fun. I mean the punch of FunFly may be less than R-lines in some points“.


Tattu R-Line VS Funfly

Tattu FunFly review: Test

Prior to any tests, I performed 3 circles of charging/discharging. As you can see in the comparison table bellow, both 1300 mAh and 1550 mAh LIPOs finished the charging process at 16.81V. The cells were almost perfectly balanced (4.20~4.21V). While the 1300 mAh LiPo ended with 1387mAh, the 1550mAH did it with 1597mAh. Both batteries remained cold during the charge (20~24 °C).

Test data


For the real world tests I used my Kopis 2SE drone, which is a powerful machine that can heavily stress any LIPO.

While the FunFly 1500mAh provided bout 1 minutes extra play time over the 1300mAh one, I felt like the extra weight made the drone less agile. Normal flight seemed the same, but flips/rolls seemed faster with the lighter pack. Both LIPOs have stable power to perform super fast punch-outs.


Last but not less important, at the end of my test fights, the battery packs remained well balanced in both cases.

Considering that these batteries are less than $20 and perform almost like R-Line packs, they seem like a good deal. Both versions can be ordered from here (you can opt for US and DE warehouse).


What I liked:

– Excellent build quality;
– Nicely priced;
– 100C, ultra high discharge rate;
– US/EU availability.

What I didn't liked:

– Available only in 4S configuration.
