About RC car lipo battery

Remote control vehicles popularly known as R/C cars are the types of cars or trucks which are powered by a battery and can be manipulated from a distance using a dedicated transmitter or remote. Readers should take note that the term R/C can also be used to refer to radio controlled vehicles. Several sources of power such as electricity and gas can be used to power remote controlled cars. Due to its numerous advantages, RC car lipo battery is strongly recommended to be used in powering remote controlled vehicles. Gens ace 5000mah lipo battery is a perfect type of power source for the remote controlled cars.

Typical RC car batteries usually get old and become frail within a short span of time. Some batteries which come with the remote controlled cars cannot be depended on upon to power effectively the vehicles bearing in mind the fact that remote controlled cars usually require a decent and lasting source of energy to ensure ultimate performance. Most of the high-end remote-controlled cars are available in the market without batteries. Users of such remote controlled cars should not worry about what type of battery to use in powering their remote-controlled automobiles since Genstattu has all the solutions to their problems.

Lipo batteries are commonly used in remote controlled appliances because of their huge advantages. Also known as lipoly battery, the lipo batteries usually dissipate large amounts of energy needed to power high-end remote control cars. Another advantage of the lipo batteries is that they are charged considerably faster than their NiMh relatives. The weight of the lipo batteries is also much less as compared to the weight of their NiMh counterparts an adaptation which facilitates swiftness of the remote controlled cars. The Gens Ace batteries are available in a variety of voltages and capacities to suit different requirements of different models of remote controlled vehicles.
One of the most common types of lipo battery utilised in powering remote controlled auto motors is the 11.1v 5000mAh lipo. This kind of lipo battery available at Gens Ace is engineered in such a way that it is capable of providing the needed power which facilitates remote controlled cars to attain the top speeds they were designed to achieve. Several other batteries of different capacities, cell counts as well as C rating are available in our online shop. Users of the lipo batteries should take note not to drain a three cell Li-Poly battery past 9.0v. To accomplish a long service life for their sets, clients should consider choosing a higher cut-off voltage lipo battery.
Remote control cars are very pleasant auto motors and can be great fun to the users. However, your experience with the remote controlled cars can be very disappointing if one does not use the correct type of battery to power them. Most of the remote controlled cars are designed to operate at a very high speed and consequently, their batteries should be very robust and up to the task. Gens ace 5000mah lipo batteries are the most suitable type of cells to be used in powering remote controlled cars. Interested clients should visit our online shop Genstattu to get to know the varieties of lipo batteries provided and their relative importance in powering different types of remote controlled cars

Which RC car lipo battery can make your RC car faster

Like the airplane model is loved by RC enthusiasts, the remote control car (RC car) is also loved by many drivers. Playing with the RC car can train up your brain, as it is a passionate sport. Here are some suggestions on how to choose RC car lipo battery or other interesting things that make your RC car faster.

At first, to choose the brushless motor

There are two types of the motor, brushed and brushless. Basically brushless motors make more power and it has parts that will hardly wear out. But if they do, you just need to change the internal parts. Whereas brushed motors have parts that are more likely to wear out. If something internal was ruined you can't replace the parts. Generally brushed motors are cheaper than brushless, that is why most of RC cars come with brushed motors in the past. But nowadays almost all RC cars use the powerful brushless motor and they are geared to hit 90mph.

At second, to choose a better RC car lipo battery

Because of most the RC cars come without a battery, so you have to choose a battery so that your RC car can start running. Which RC car lipo battery is most important can make the RC car faster? We will recommend you the Gens ace&Tattu RC car lipo battery, they both have very high-capacity, high-discharge rate.

How to extend battery life and why use frequently can keep the battery best performance?

If the traditional Ni battery is charged for too long, the liquid inside would crystallize. In the way, to maximize the performance, the full charge and discharge are required. However, for the 2 cell Lipo battery, we can charge it whenever we are convenient.

It is a false about the lifespan of lipo battery that we should replace the lipo battery after charged for 300-500 times.

Instead, the factor influenced the lifespan is the charging cycle, and the times of charging will not directly influence the lifespan.

A charging cycle refers to the period from full power to the completely empty power and then fully charged. That does not mean charging for one time, as the following picture shows.

According to the picture, the battery is charged for 20% after the first time 40%. Then, after consumed some power, it is charged by 30% and 20% separately. In the half of this 20% (at the time of 10%), a charging cycle has been finished. And then, the next cycle begins.

For example, the first day, we charge the battery after consumed half of the power, and the second day, we repeat that process. This is just one charging cycle rather than two. Therefore, a cycle may be finished by several times of charging. Every single charging cycle will reduce the power slightly. However, a superior battery can maintain 80% power after many charging cycles. That is why some lipo battery can use normally after two or three years. Certainly, it is also needed that we replace the lipo battery if the lifespan has ended.
The lifespan of lipo battery is commonly 300-500 charging cycle. We set the Q as the power provided by one-time fully discharging. Ignoring the reduction of every charging cycle, the lipo battery can power 300Q-500Q through its lifespan. Accordingly, if we charge the battery after consuming ? power, the battery could be charged for 600-1000 times. (if we charge the battery after consuming 1/3 power, the battery could be charged for 900-1500 times.) we cannot tell the exact number of charging times if we charge randomly. In a word, the total power 300Q-500Q is constant. Therefore, the lifespan is related to the total charging power rather than the charging times. Besides, the difference between the influence of deep charging and discharging and the influence of light charging and discharging to lipo's lifespan is similar.

In fact, light charging and light discharging benefit more to the RC lipo battery. Only when the lipo battery is calibrated by the product has the need to charge and discharge battery deeply. Therefore, we can use the lipo battery for convenience and do not have to concern about the lifespan.

If the lipo battery is used above the regulated temperature (over 35 degree centigrade), the power will continuously decrease, which means the flight time would not be so long. If charged under the high temperature, the battery would be further damaged. It is unavoidable that storing under the high temperature will hurt the battery's quality.
If using below the 4 degree centigrade, you would also find the flight time of the battery has been reduced, and even some original lipo batteries of mobile phones cannot be charged. But, this situation is just temporary. Differ from using in the high temperature, once the temperature gets higher and the molecules inside the battery are heated, the battery would recover to the normal energy.
To maximize the performance of lipo battery, we should use it more often and make the electron flow. If we cannot use the lipo battery frequently, please remember to make a charging cycle and calibrate it (charge and discharge deeply) every month.

The lipo battery characteristics and applications

Due to the good characteristics, the lipo battery is widely applied in mobile phones, cameras, laptops, cordless telephone, remote control, electronic toys and other electronic devices.

Li battery, nickel-cadmium battery and NI-MH battery

The cathode material of Lithium-ion battery is graphite crystal, and the anode material is Lithium superoxide (LiO2). In the charging process, Li-ion moves from anode to cathode and embeds in the graphite layer. In the discharging process, Li-ion separates from the cathode of graphite crystal and moves to anode. Apparently, Lithium is always appeared as Li-ion rather than Lithium metal in both charging and discharging process. Consequently, this kind of battery is called Li-ion battery, Lipo battery in short.

The advantages of Lipo batteries are small volume, huge capacity, light weight, non-pollution, high voltage of single cell, low self-discharging rate, more cycle times, but its price is comparatively high. Nickel - cadmium battery is gradually being replaced because of the low capacity, serious self-discharging and the pollution to the environment. NI-MH battery (nickel-metal hydride battery) is cost-efficient and eco-friendly, but since its single cell voltage is only 1.2V, it has some restrictions in the application.

The lipo battery characteristics

1. higher weight-energy rate, volume-energy rate.
2. high voltage. The single cell voltage is 3.6V, which equals to 3 nickel-cadmium battery or NI-MH battery put in series.
3.Keep for long because of the low self-discharging rate. (This is the most obvious advantage)
4. no memory effect. Lipo battery does not have the so-called memory effect as Lithium-cadmium battery, so there is no need to discharge it before charging.
5. Long lifespan. In the common working condition, the cycle times of charging and discharging is more than 500.
6.charging quickly. 0.5 to 1 time of current can be applied to the charging process, and the charging time can be shortened to 1-2 hours.
7. can be used in parallel
8. It is the most advanced "green" battery of the world, because it does not threaten the environment and does not have the heavy metal element like cadmium, lead or mercury.
9. high cost. Compared with other kinds of batteries, the Lipo battery is more expensive.

The internal structure of Lipo battery.

Lipo battery is often divided into cylinder and rectangular.

The internal structure is spiral, which puts a very precise and highly permeable polyethylene film between cathode and anode as a partition. The anode consists of the Li-ion collector made in Lithium and CoO2 and the current collector made in aluminum film. The cathode consists of Li-ion collector made in Carbon sheet materials and current collector made in bronze film. The battery is filled with organic electrolyte solution. Besides, there are safety valve and PTC component protecting the battery in the abnormality or short out.

The voltage of single cell is 3.6V, which is not the infinite capacity. Therefore, it is common to put the single li battery in series or in parallel to meet any demands.

The charging and discharging requirements of Lipo battery

1. The charging of Li battery: according to the structural characteristics, the maximum charging voltage of li battery is 4.2V. Over charging is prohibited as the battery would be damaged if the Li-ion from anode is taken too much. The charging and discharging process are demanding, so we can use the professional constant current, constant voltage charger. When the battery's voltage reaches 4.2V in the constant current charging mode, the battery would be charged in the constant voltage mode. And when the current lowers the 100 mA, it should be stop charging.
Charging current=0.1-1.5 times of the battery capacity. (e.g. The charging current could be 105-1575Ma for the 1050mAh battery.)

2.The discharging of Lipo battery: due to the internal structure, the li-ion cannot move to anode completely in the discharging process. A part of Li- ion should be kept in cathode to guarantee the Li-ion can embed in the channel freely, or the lifespan would be shortened. To ensure that there is some Li-ion in the graphite layer after discharging, the minimum ultimate discharging voltage should be restricted. In other words, Lipo battery cannot over discharge. The common ultimate discharging voltage is 3.0V/cell, cannot lower than 2.5V/cell. The time of discharging depends on the battery capacity and discharging current. Discharging time(hours)=battery capacity/discharging current. Discharging current of Lipo battery(mA) cannot exceed three times of battery capacity. (e.g.10000mAH battery should charged in the current of 30A, or it will damage.)
There are protecting plates in the internal Lipo battery group, so just control the external charging and discharging current.

The protective circuit of Lipo battery

The protective circuit of two cells consists of the two field-effect tube and dedicated protective manifold block; overcharging control valve and over discharging control valve are in the circuit in series, which is supervised and controlled by the protective IC. When voltage reaches up to 4.2V, the overcharging protective tube stops and charging ends. To avoid mistakes, delayed capacitance is added to external circuit. In the discharging process, when the voltage becomes 2.55V, over discharging control valve stops charging the load. Over-current protection is that stops discharging the load when large current flows across the load, which aims at protecting battery and field-effect tube. Over-current test is to use the on resistance of field-effect tube as the test resistance and supervise the voltage drop, stopping charging when exceed the set value. There is delayed circuit in the circuit to differ the surge current and short-circuit current. That circuit has complete function, reliable performance. It is professional and the manifold block cannot be purchased easily, so the amateurs are hard to fabricate.

The difference between li-ion and li-polymer battery

Lipo batteries often refer to the polymer lithium batteries. According to the electrolyte materials, Li-ion battery is divided into liquid lithium ion battery and polymer lithium battery or plastic lithium battery. Do you know what are the difference between li-ion and li-polymer battery? Let us review these common senses with Gens Ace.

The difference between li-ion and li-polymer battery

Compare with li-ion battery,lipolymer battery has the following characterizations:
1. It would not leak the electrolyte, since it uses the colloidal solid rather than the liquid electrolyte.
2. It can be made into thin battery. For example, a 3.6V 400mAh 15C battery can have the thickness of 0.5mm.
3. It can be designed into multiple shapes.
4. The battery can distort and be flexible. The macromolecule battery can distort up to 900 around.
5. It can be made into single high voltage: the battery with liquid electrolyte can only acquire the high voltage and macromolecule battery by putting several batteries in series.
6. Because the battery itself does not have liquid, it is possible to obtain high voltage by making multi-layer combination inside the single battery.
7. The capacity is twice as that of the Li-ion battery.

The lifespan of lipo battery

The factor influenced the lifespan is the charging cycle, and the times of charging will not directly influence the lifespan.

For example, the first day, we charge the battery after consumed half of the power, and the second day, we repeat that process. This is just one charging cycle rather than two. Therefore, a cycle may be finished by several times of charging. Every single charging cycle will reduce the power slightly. However, a superior battery can maintain 80% power after many charging cycles. That is why some lipo battery can use normally after two or three years. Certainly, it is also needed that we replace the lipo battery if the lifespan has ended.

The lifespan of lipo battery is commonly 300-500 charging cycle. We set the Q as the power provided by one-time fully discharging. Ignoring the reduction of every charging cycle, the lipo battery can power 300Q-500Q through its lifespan. Accordingly, if we charge the battery after consuming power, the battery could be charged for 600-1000 times. (if we charge the battery after consuming 1/3 power, the battery could be charged for 900-1500 times.) we cannot tell the exact number of charging times if we charge randomly. In a word, the total power 300Q-500Q is constant. Therefore, the lifespan is related to the total charging power rather than the charging times. Besides, the difference between the influence of deep charging and discharging and the influence of light charging and discharging to lipo's lifespan is similar.

In fact, light charging and light discharging benefit more to the lipo battery. Only when the lipo battery is calibrated by the product has the need to charge and discharge battery deeply. Therefore, we can use the lipo battery for convenience and do not have to concern about the lifespan.

If the 2 cell lipo battery is used above the regulated temperature (over 35 degree centigrade), the power will continuously decrease, which means the flight time would not be so long. If charged under the high temperature, the battery would be further damaged. It is unavoidable that storing under the high temperature will hurt the battery's quality.

If using below the 4 degree centigrade, you would also find the flight time of the battery has been reduced, and even some original lipo batteries of mobile phones cannot be charged. But, this situation is just temporary. Differ from using in the high temperature, once the temperature gets higher and the molecules inside the battery are heated, the battery would recover to the normal energy.

To maximize the performance of lipo battery, we should use it more often and make the electron flow. If we cannot use the lipo battery frequently, please remember to make a charging cycle and calibrate it (charge and discharge deeply) every month.
