5 advantages of graphene Lipo batteries

Graphene Lipo battery becomes more and more popular. There are many well-known brands on the market, such as Hobbyking, Dinogy, Lumenier and so on. This shows the popularity of graphene Lipo batteries. Our company also launched graphene Lipo battery as early as 2016 when we launched the DOGCOM brand.

Our graphene Lipo battery offers the following advantages over normal Lipo battery:

(1)Higher Cycle Life Retention rate.In the cycle life test of 1C charging and 1C discharging, the capacity retention rate is more than 96% after 200 weeks.

(2)Higher discharge rate performance.Under the condition of high discharge rate, the discharge platform is still kept high. In the 65C power discharge test, the capacity retention rate can reach 90% of the 1C discharge capacity, and the discharge platform is higher than 3.45v.

(3)With the ability to charge quickly. In the 10C charging cycle test, the capacity retention rate was still over90% after 100 cycles.

(4)The lower the temperature at which the current is discharged.Because of its high thermal conductivity, graphene batteries have a lower surface temperature when tested at high rates of discharge. In 10C, 20C, 30C, 40C, 50C, 60C, 70C room temperature (25 C) discharge test, the highest temperature does not exceed 65 C.

(5)Good safety performance. Graphene batteries can pass vibration, free fall, heat abuse,

"Tranquiity base; the Eagle has landed."

"One giant leap for mankind".

July 16th 1969, I was just approaching 15 years old. A group of young lads from school went around to a friend's house who was only one with a colour TV to watch the launch of the mighty Saturn V.

I begged my father to be allowed to watch the moon landing live on our TV on July 20th. The program was scheduled for 03:00 in the morning in the UK and needing to get up for work a few hours later he refused, telling me I could watch it on the news later that day. I was obsessed with the moon race and never forgave him for denying me the chance to watch it live, even ribbing him about it to this day!

Here in commemoration of that historic event 50 years ago is the Eagle.

Landing gear is retractable, radio dishes and antenna respond to the controls.

Derived from a SketchUp model by Fort Opus.

A microcontroller is a single-chip microcomputer that integrates the main part of a microcomputer on a single chip. Microcontrollers were born in the mid-1970s. After more than 20 years of development, their cost is getting lower and lower, and their performance is getting stronger and stronger, which makes their applications ubiquitous in all fields. Examples include motor control, bar code readers/scanners, consumer electronics, gaming equipment, telephones, HVAC, building security and access control, industrial control and automation, and white goods (washing machines, microwave ovens).

The role of the microcontroller
In industrial applications, the role of the microcontroller is to control and coordinate the actions of the entire device, usually requiring a program counter (PC), an instruction register (IR), an instruction decoder (ID), timing and control circuitry, and a pulse source. Interrupts, etc. are completed together.

According to the role played by the controller in the work, the main types of microcontrollers are as follows:

1, command controller

The instruction controller is a very important part of the controller. It needs to complete operations such as fetching instructions and analyzing instructions, and then handing it over to the execution unit (ALU or FPU) for execution, and also to form the address of the next instruction.

2, timing controller

The purpose of the timing controller is to provide control signals for each instruction in...Continue Reading

I was timing for a pilot during a recent Altidude Limiting Endurance contest (ALES). Most pilots were using the Radian motorglider and having trouble landing within the landing circle. Most were landing outside and getting zero landing points. The Radian has no flaps or spoilers so approach planning and touchdown is non standard. A random circling approach or a low fast approach is about all you can do. When you want to come to a stop you nose her in to the grass and hope that the spinner, prop, and motor are not damaged. Of course if you use motor you save your Radian but get a zero for the flight.

The stock Radian comes with a white plastic skeg that is about 1/4 high and protects the white foam from getting scratched. If the plastic supported a music wire skeg I think it would improve the concept of protecting the prop and also improve spot landings in grass and other runway surfaces.

The following pic and diagram shows the concept of the music wire skeg mod. I will be testing a main wheel and rudder wheel for maneuvering on the grass and hard runway with my Night Radian. Other ideas are encouraged and welcomed.
