What is the 7.2 Volt RC Battery ?

7.2 Volt RC Battery, we also call it 7.2V RC Battery. Here we mainly describe in detail the batteries for remote control toys, models, remote control tanks, remote control boats, remote control naval vehicles, remote control motorcycles, DIY models, Airsoft, etc. Such batteries with 7.2V voltage are generally divided into 3 types of materials. Each material has its own advantages. Let's introduce it in detail below.

What is the 7.2v NiMH RC Battery pack?

7.2V NiMH is an abbreviation for nickel-metal hydride. 7.2V NiMH is a nickel-metal hydride battery, which means that its voltage is 7.2V and the material is NiMH. Its positive electrode is Nio and the negative electrode is metal hydride because it is cheap and very strong and popular. It is widely used in toys such as remote control car toys, remote control tanks, remote control boats, remote control robots, remote control models, low-use electrical machines, etc. on.

Ni-MH batteries are our most common rechargeable batteries in consumer electronics. Due to its superior chemical properties, Ni-MH batteries have replaced Ni-Cd battery applications. Since NiMH does not use cadmium (the use of toxic chemicals in battery applications) and also does not have the same memory problems that plague NiCD, NiMH batteries are a better choice. At the same time, portable high-power solutions are one of the most popular solutions in battery applications. Today, let’s learn about the techniques of using Ni-MH batteries!

What are the classifications of Ni-MH batteries?

We usually see nickel-metal hydride battery packs composed of multiple single cells connected in series. Compared with lithium-polymer batteries (LiPO), NiMH batteries are safer to use. The rated voltage of each individual battery is 1.2V, which means that we see that the rated voltage of the Ni-MH battery pack is a multiple of 1.2V. In particular, we provide 1.2 Volt, 2.4 Volt, 3.6 Volt, 4.8 Volt, 6.0Volt, 7.2 Volt, and 8.4 Volt battery packs.

Regardless of the physical size of the battery, the rated voltage of each Ni-MH battery is 1.2V. The physical size of the battery indicates the capacity of the battery. Generally, the larger the battery, the greater the mAh of the battery.

Classification and characteristics of Ni-MH batteries:

Ni-MH batteries are divided into high-voltage nickel-hydrogen batteries and low-voltage nickel-hydrogen batteries. 7.2V NiMH batteries are high-voltage lithium batteries.

7.2 Volt high voltage Ni-MH battery has the following characteristics: (1) High reliability. It has better over-discharge and over-charge protection can withstand higher charge-discharge rates and has no dendrite formation. Has good specific characteristics. Its mass-specific capacity is 60A·h/kg, which is 5 times that of cadmium-nickel batteries.
(2) Long cycle life, up to thousands of times.
(3) Compared with nickel-cadmium batteries, it is fully sealed and less maintenance.
(4) Excellent low-temperature performance, the capacity does not change significantly at -10°C.

Low-voltage Ni-MH batteries have the following characteristics:
(1) The battery voltage is 1.2~1.3V, which is equivalent to nickel-cadmium batteries;
(2) High energy density, more than 1.5 times that of cadmium-nickel batteries;
(3) Quick charge and discharge, good low-temperature performance;
(4) It can be sealed and has strong resistance to overcharge and discharge;
(5) No dendrites are formed, which can prevent short circuits in the battery;
(6) Safe and reliable, no pollution to the environment, no memory effect, etc.

Maintenance during use

Pay attention to maintenance when using Ni-MH batteries.

(1) Avoid overcharging during use. During the cycle life, avoid overcharging during use. This is because overcharging can easily cause the positive and negative electrodes to swell, causing the active material to fall off, the diaphragm is damaged, the conductive network is damaged, and the ohmic polarization of the battery becomes larger.

(2) Prevent the deterioration of electrolyte. During the cycle life of Ni-MH batteries, hydrogen evolution should be suppressed.

(3) Storage of Ni-MH batteries. The storage of Ni-MH batteries should be fully charged. If the battery is stored for a long time without storing electric energy in the battery, the function of the battery's negative hydrogen storage alloy will be weakened and the battery life will be shortened.

Advantages and disadvantages of NiMH battery

1. Advantages: Its advantages are price and hardness. Generally, NiMH batteries are very cheap, much cheaper than lithium batteries, have high hardness, and are relatively strong and not easy to deform. Compared with nickel-cadmium batteries, it has many advantages, such as lighter weight and longer life.

2. Disadvantages: average performance, memory effect, and pollution. However, the performance of NiMH batteries is very general compared to lithium batteries, which can be described as poor. And its lifespan is not very long, each time it needs to be discharged and then recharged, so the mobile phone that wakes up early needs to be fully discharged and then recharged after being bought, while the current lithium battery does not need to be discharged and recharged.

NiMH battery charging method

First of all, we need to prepare a special charger for the NiMH battery, because using other chargers will affect its life. Then first discharge the NiMH battery, and then charge it. Each charge takes about 10-20 hours. It cannot be charged for a long time. Overcharge can easily damage the NiMH battery. Normally, the number of recharges for NiMH is 2000 times, after which it will decay.

Which is better, NiMH or NiCD?

NiMH is better in theory, but the two have their own characteristics. NiMH is called nickel-metal hydride battery, and NiCD is called nickel-cadmium battery. In terms of weight, NiMH is lighter; in terms of life span, NiMH is longer; in terms of performance, NiMH is also stronger; but in terms of price, NiMH is more expensive than NiCD, so you need to consider cost performance when choosing. If it is cheaper, choose the NiCD it is also fine.

What is the 7.2v NiCD RC battery pack?

Introduction:

Nickel-Cadmium Batteries (Ni-Cd, Nickel-Cadmium Batteries, Ni-Cd Rechargeable Battery) are the earliest types of batteries used in mobile phones, Supertech, RC toys car, and other devices. They have good high-current discharge characteristics, strong overcharge, and discharge resistance, and maintenance Simple, generally use the following reaction discharge:
Cd+2NiO(OH)+2=2+
The reaction is opposite when charging.
Nickel-cadmium batteries
The most fatal disadvantage of nickel-cadmium batteries is that if they are improperly handled during charging and discharging, serious "memory effects" will occur, which greatly shortens the service life. The so-called "memory effect" means that the battery's power is not completely discharged before the battery is charged, which will cause the battery capacity to decrease over time. During the battery charging and discharging process (discharge is more obvious), a little bit will be generated on the battery plate. The accumulation of these bubbles reduces the area of ​​the battery plate and indirectly affects the battery capacity. Of course, we can reduce the "memory effect" by mastering reasonable charging and discharging methods. In addition, cadmium is toxic, so nickel-cadmium batteries are not conducive to the protection of the ecological environment. Numerous shortcomings make nickel-cadmium batteries have basically been eliminated from the scope of application of digital equipment batteries.

Detailed description

Cadmium batteries can be charged and discharged more than 500 times, economical and durable. Its internal resistance is small, not only the internal resistance is small, it can be quickly charged, but also can provide a large current for the load, and the voltage change is small during discharge, which is a very ideal DC power supply battery. Compared with other types of batteries, nickel-cadmium batteries can withstand overcharge or over-discharge. The discharge voltage of nickel-cadmium batteries varies according to their discharge devices

Basic features

What is the 7.2v Lithium Battery Pack?

Lithium battery refers to a battery containing lithium (including metallic lithium du, lithium alloy, lithium-ion, and lithium polymer) in the chemical system of electricity. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium-ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable.

(Lithium-ion battery) Li-ion battery is a kind of rechargeable battery, which mainly relies on the movement of lithium ions between the positive and negative electrodes to work.

During charging and discharging, Li+ ions intercalate and desorb back and forth between the two electrodes.

When recharging the battery, Li+ ions are separated from the positive electrode and inserted into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state;
The opposite is true when discharging. Generally, batteries containing lithium elements are used as electrodes.
In the market, we can often see LIPO Battery, Lithium-ion battery( Li-ion battery), they all belong to the Lithium battery.

The advantages of lithium-ion battery

1. Small size, light weight, and high specific energy. The volume of lithium-ion batteries is 30% smaller than that of nickel-metal hydride batteries, the weight is less than 50%, and the specific energy is twice higher than that of nickel-cadmium batteries.

2. High voltage and long life. The voltage of the lithium-ion battery is 3.6V, and the service life can reach more than 1000 times, far exceeding other batteries.

3. No memory effect, low self-discharge, and long use time.

4. Good safety performance, fast charging, wide operating temperature range.

Before the application of mobile phone batteries, the performance test is indispensable. The shrapnel micro-needle module can be used as the battery test module, which can transmit large current, adapt to small pitch, has good over-current capability, and can ensure the test of mobile phone battery stability.

.

Do LiPo batteries make RC cars faster?

Generally speaking, the LIPO battery or NiMH battery used for the model remote control car has a discharge rate of 15C. When the battery with the same voltage is used, the speed is the same. The only difference is that with the same discharge rate, the same capacity, and the same voltage, the lithium battery will run longer. Because it is lighter.

Can I use a 7.4 V battery instead of 7.2 V?

If used for remote control cars, remote control models, etc., it is generally possible. Because the voltage is not much different, the damage to the toy is generally not too great.
If it is used on more expensive items, it is recommended not to use it.
The last thing to pay attention to. NiMH battery does not have 7.4V. Generally, 7.4V batteries are lithium batteries, such as 18650 batteries. When they are charging, they need a special charger for lithium batteries to be used. The NiMH charger can only charge the NiMH battery. Remember.

How to choose the Right 7.2v Battery Pack for RC Cars?

There are 4 types of batteries on the market for remote control car models. They are 7.2V NiMH, 7.2V NiCD, and 7.2V lithium (include the lipo or li-ion battery), LiFe.

The Classification of RC 7.2v battery pack

NiCD, nickel-cadmium battery.

This type of battery is an old type with low cost, low capacity, and memory effect. Now it can only be found on some cheap toy cars, it is strongly not recommended.

NiMH, nickel-hydrogen battery.

Among AA and AAA batteries, NiMH batteries are definitely the mainstream. However, the batteries of remote control models have slowly withdrawn from the stage of history, but they still occupy a large proportion in the market.

lithium Battery

LiPo, lithium polymer battery, LIpo battery, or li-ion battery are the mainstream types in the current model. Widely used, with various models, various discharge rates, and very large types. There are also many styles to choose from.

LiFe Battery

LiFe, lithium iron battery, is not too mainstream. It is generally used for remote control, or for petrol cars to receive electricity, but it is rarely used as power for trams.

Currently, there are mainly two types of secondary batteries in use on the market: Ni-MH and Li-ion. Lithium-ion batteries have been mass-produced liquid lithium-ion batteries (LiB) and polymer lithium-ion batteries (LiP). Therefore, in many cases, the battery marked with Li-ion must be a lithium-ion battery. But it is not necessarily a liquid lithium-ion battery, it may also be a polymer lithium-ion battery.

The lithium-ion battery is an improved product of lithium batteries. Lithium batteries have existed a long time ago, but lithium is a highly active metal (remember its position in the periodic table?). It is not safe to use and often burns and bursts during charging. The situation, later, there was an improved lithium-ion battery, adding ingredients that can inhibit the active lithium element (such as cobalt, manganese, etc.) so that the lithium battery is truly safe, efficient, and convenient, and the old lithium battery will follow. Basically eliminated. As for how to distinguish between them, it can be identified from the battery logo, lithium batteries are Li, and lithium-ion batteries are Li-ion.

4 Details to choose the Right 7.2v rc car battery.

    Usually the RC battery was used in all kinds of toys, such as RC Cars, remote control aircraft, RC tanks,RC Drone,RC Quadco[pter,RC Hexacopter,RC Robots, etc.

rc battery example 1

1. Choose the right voltage. The battery pack's voltage is the same.

That means, the V number is the same, the volt is the same. Look the picture above, you can see the voltage is 4.8V or 4.8 Volt

2. Choose the right Size.

The shape and size of the battery pack are the same. or you can put the battery inside the toys is ok. ( See The left picture show: the shape is "1 Row with 4X Small AA battery", the battery size is:56X50mm, so your battery must match your battery, then can be put into your toys .)

3. Choose the right connector. The battery pack Connector is the same.

(See The left picture show: it has many Connector, such as Standard Tamiya Connector, small Tamiya connector, SM Connector, JST Connector, Air-to-Air Connector, 2P HuanQi Connector,etc. )

4. Choose the right Discharge coefficient.

For the "NiMH battery, NiCD Battery, lipo battery", it has a Discharge coefficient(It short for "C"), just 15c, 20c, 25C, etc. This Discharge coefficient represents the Battery discharge speed. the larger the C value, the faster the discharge speed.
    So if the Capacity is the same ,the more C value,the more speed or more power for your toys . Meanwhile, the running time will become shorter .

Therefore, for the RC Helicopter, RC Drone, Upgraded brushless RC cars, which requires the fast speed or stronger power. You can purchase a discharge coefficient of at least 15C. Also choose 15C, 20C,25C is ok.

Usually, For the RC Helicopter and Drone, the discharge coefficient is at least 15C.

For the Other RC Toys Car, You don't need to care about it. For the Upgrade brushless Car And RC Boat, the discharge coefficient is at least 15C.

For the ordinary toys, RC TOYS CAR, RC toy boat, RC ROBOTS, RC TANK, and remote control robots, you do not need to consider these issues.

If you buy the battery for the Radios, household appliances, we suggest you choose the low Discharge coefficient.like 5C. Or it maybe burns the product.

Generally, If matching the above four conditions, this battery pack can be fit for your toys.

For Example:The left picture show:NiMH AA 3500MAH 4.8V ,So the Volt is 4.8V(Also called 4.8 Volt);the capacity is 3500mah,the Battery material:MINH(Also called NI-MH.);The Battery size is 56X50mm;The Battery shape is :1 Row with 4x AA small Battery.You must have the Same Volt, Same size, same shape. Then you can use this battery.

 

Need to pay attention

1. Battery Capacity(MAH): the "mah" represents the capacity of the battery, it does not affect the use. the larger the mAh, the longer the using time
2. Battery Weight: If the battery's weight is different, usually it does not affect the use of your toys. Because usually the heavier the battery, the bigger the capacity. So usually you do not need to consider these issues. But for the RC Drone, You'd better choose the LIPO Battery, because it has a Lighter weight than NiMH And NiCD Battery.
3. Battery shape and size:Different voltage battery packs have different sizes and shapes. So please check carefully for the shape and size, if they are the same or your toys' battery space is big enough, you can buy the same size battery or bigger size battery.

What voltage should I charge a 7.2 V battery?

When you buy a charger, please check its label carefully. If the label indicates that the output voltage is 7.2V, it is fine. Don't try other chargers.

Can I charge a 7.2 V battery with a 12v charger?

The output voltage of the 12V charger is too high and it will break down the battery. If it is not allowed, only the output voltage of 7.2V can be used.

How to choose the 7.2 Volt battery charger fo the RC Cars

1. Choose a professionally certified charger.

First of all, it must be clear that the charger is a high-loss product, and you must buy the kind of high-quality charger that has passed industry certification, otherwise, it is easy to damage. All chargers in our shop are authentic products that have passed industry safety certification. For all 7.2V NiMH battery chargers, you can buy from our website. This link.

In the choice of charger brands, use those old brands as much as possible. For example, Grignard’s IMAXB6 multifunctional lithium battery intelligent balance charger, IMAXB6 balance charge is suitable for LI-ION (lithium-ion battery), LI-POLY (lithium polymer battery), LI-FE (lithium iron battery), NiCD (nickel-cadmium) Batteries) NiMH (nickel-metal hydride battery) and PB (lead-acid battery), covering mainstream models. Rechargeable battery types include car models, RC Boat model, and aircraft model batteries.

2. It must be clear what material your battery is made of.

You must clearly know whether your battery is a NiMH battery, a NiCD battery, or a lipo battery. For batteries of different materials, different chargers must be selected, otherwise, they cannot be charged.
Especially the NiMH battery charger can only charge the NiMH battery, not other NiCD and lipo batteries. The lithium battery charger can only charge the lithium battery. Please, Remember these.

3. A charger with the same output voltage must be selected.

Such as a 7.2V NiMH charger. Then you will see the output 7.2V at its label. If the voltage is constant, then look at the output current.

4. The charger plug must match your battery all the time, otherwise, it cannot be connected together.

5. Two types of chargers can be selected

A. USB interface charger. Generally, the USB charger can be charged using the charging head of the mobile phone, the USB port of the computer, and the power bank. Convenient for charging when playing outside. Generally, we recommend buying a charger with automatic power-off protection. When the battery is fully charged, the USB charger will automatically power off.
At the same time, for the automatic power-off charger, it has IC charging protection. It can prevent overcharge and overvoltage. When charging, the indicator light will flash. When the battery is fully charged, the indicator light will go out.

B. Socket Charger. This socket charger can directly charge on the socket. The color of the light is red when charging, the light will not go off when it is full, and the color will be slightly darker!

6. Charger charging time

Some people will ask how long the battery pack can be fully charged normally? In fact, the output parameters of the charger are different, the charging time is different, the charger is full of lights will change, the normal charging time is generally about 2-4 hours.

How long do you charge a 7.2 V RC battery ?

Generally speaking, battery capacity divided by charger output current = charging time

1. It takes 6 hours to charge the 7.2V1800mAh battery with a 300mA output current charger (1800mAh except du300mAh);

2. It takes about 13 hours to charge a 7.2V3800mAh battery with a 300mA output current charger (3800mAh except 300mAh);

7.2V open circuit voltage charger, after charging, the voltage is about 8.5-9.0V.
The open circuit voltage of a single rechargeable battery is 1.2V, and the upper limit of charging is within 1.48V-1.50V. And 7.2V is exactly 6 batteries in parallel, so the open circuit voltage of 7.2V battery is 1.2V*6=7.2V.
The upper limit of charging is within 8.88V to 9V. (The calculation method is as follows: 1.48V*6=8.88V, -1.50V*6=9V)

A. How long does a 5000mah RC battery last?

First, let’s check the output current on the charger label. At present, the output current of the 7.2V Minh charger is generally 250MAH. The theoretical charging time is: battery capacity 5000MA ÷ charging current 250MA*1.2=24 hours.
So the normal charging time is about 24 hours. This is obviously slow,
So we need to buy a Ni-MH fast charger similar to A3, which can be charged in 6 hours. The calculation formula is as follows: The output current is about 2A, 5000mah/2000mah*1.2=6 hours.

How long does it take to charge a 7.2 V 2000mah NI MH battery?

First, select the NiMH charger with an output voltage of 7.2V Secondly, the plug of the charger should be matched, and the positive and negative poles should be the same. Otherwise, it will short circuit and burn out the charger. Finally, try to choose a higher input current, such as 2A output current, so that it can be charged in 2.4 hours.

6 Tips You must know before using the 7.2V RC Car Battery

Battery maintenance has always been a problem that everyone is more concerned about. Here we will introduce it in detail.

Battery life refers to the number of charging and discharging before the capacity of charging and discharging drops to 80% of the nominal capacity after a period of use. It does not mean that the battery cannot be charged or discharged or is completely failed. /

the self-discharge rate refers to the battery after it is fully charged The phenomenon of slow self-discharge when left unused for a long time. The low self-discharge rate indicates that the capacity drops less after long-term storage.

For outings to shoot programs or news interviews, portable video recording equipment is generally used. The batteries used with portable video recording equipment are a vital part of ensuring efficient and high-quality continuous long-term work to ensure the smooth progress of filming work. The normal function of the battery is closely related to the correct use and careful maintenance of our TV and audio-visual workers in their daily work, so the use and maintenance issues should arouse our attention.

1. In daily work, you should be familiar with the type of battery you use, its basic characteristics, and performance. This is of great significance to guide us in the correct use and maintenance, and it is also extremely important to extend the service life of the battery.

2. When charging, the room temperature should be controlled between 10°C and 30°C. If the temperature is higher than 30°C, it is better to take cooling measures to avoid deformation due to overheating inside the battery; when the room temperature is lower than 5°C, insufficient charging will occur. Affect battery life.

3. After the battery has been used for some time, due to different discharge levels and aging, there are more or less insufficient charging and performance degradation. Generally, nickel-cadmium batteries can be used after about 10 charge and discharge cycles. Recharge. The method is to extend the charging time by about twice the normal charging time. A specific example is as follows: Use SONY's BC-1WA(B) charger to charge the NP-1 battery. When the green light flashes, it is fast charging. When the green light stops flashing and stays on, the fast charging ends. The drip charging starts. When the drip charging time is extended, The drip charge time is the overcharge time, and the overcharge time is preferably 3-4 hours.

4. Battery charging and discharging should be operated in strict accordance with the requirements, and avoid long-term overcharge, over-discharge, or frequent undercharge. Incomplete discharge, long-term low-current deep discharge, or short-circuit during battery use are all important factors that cause the decrease of battery capacity and shortened life. In the long run, illegal use and operation will not only affect the use of the battery but will inevitably affect the capacity and life of the battery.

5. In the commonly used BC-1WA(B) charger, the battery charging process should be completed at one time. Do not cut off the power halfway or after the fast charging is over, the battery is in a high-temperature state, and the power is turned on again so that the charger can quickly charge the battery again Charging will result in overcharging. When the battery warning indicator flashes during use, the battery should be replaced in time to avoid excessive battery discharge.

6. Nickel-cadmium batteries( Ni-Cd ) do not need to be charged and stored when they are not used for a long time. When we are ready to save, we need to discharge the battery to the termination voltage (the camera battery warning light flashes) before it can be packaged and stored in the original packaging carton. It can also be packed in cloth or paper and stored in a dry and ventilated place.

How do you make a 7.2 Volt battery pack?

First find a bunch of 3.2V 18650 batteries. Use thick copper enameled wire as the connecting wire, first paint and tin, and then solder on the battery electrodes. Next, polish the electrode smoothly. Then connect two 3.2V battery packs in series to form a 7.2V battery. This is a successful production.

For example, here we want to make a 7.2V 2000MAH battery, using two 3.6V2000mAh 18650 single cells, through two series combination to form a 7.2V2000mAh.

Finally, it should be noted that if it is a lithium battery pack, a supporting protection board is required, and it is recommended to choose 2 strings of lithium battery protection boards.

7.2V RC Battery FAQ

What battery do I need for my RC car?

Generally speaking, remote control cars use NiMH batteries or lithium batteries. So you only need to open the original battery. Generally, there will be a label on the original battery. The label will indicate that the material of the battery is Li-ION, LiPo, NiMH, or NiCD At the same time, the voltage and capacity of the battery will be indicated on the label. For example, there is a 6V 800MAH NIMH Battery. It means that the battery voltage is 6V, the capacity is 800mah, and the material is Nimh battery.
When you know these parameters clearly, you can purchase the corresponding battery in our store. If you still have unclear questions, you can also contact us by email, rchobbies@qq.com. We will contact you as soon as we receive the question.

What is the best charge rate for NiMH batteries?

If you want to add the efficiency rate of the charger, then you cannot answer. The conversion efficiency rate of each type of charger is different. If you calculate the charging efficiency of a certain battery, you generally ignore the charger and only calculate the charge. Charge the battery power during the process.
And the charging efficiency of the battery is related to the charging method of the charger, and it mainly includes: constant current type, constant voltage type and pulse.
I don’t know the charging efficiency of Ni-MH, I only know that the lithium battery is charged by pulse mode to over 90%

Does LiPo Battery last longer than NiMH Battery?

Compared with Ni-MH batteries, Lithium batteries still have a longer lifespan. However, Ni-MH batteries have two disadvantages. One disadvantage is that the charging time is particularly long, and the other is that Ni-MH batteries are both It has memory, and it can be recharged after the power in the battery is discharged. Unlike lithium batteries, which can be charged at any time, this is the most troublesome problem.

Can you overcharge a RC car battery?

It can be sealed and has a strong resistance to overcharge and discharge. At the same time, current chargers generally have automatic protection functions. When it is full, it will no longer be charged. But please note that the time for a single charge should not exceed 24 hours. Otherwise, it is easily damaged.

Can I put a higher voltage battery in my RC car?

Under normal circumstances, it is not allowed, because the battery voltage is too high to burn the circuit board. But sometimes, for example, 7.2V nimh battery uses 7.4V lithium battery. A 3.7V lithium battery for the 4V remote control car battery is also possible. The power will be stronger.

Can I charge a 7.2 V battery with a 9.6 V charger?

This is not allowed. Because the charging voltage is too high. A continuous charging current will burn out the battery. A charger with an output voltage of 7.2V should be selected. Generally, there will be a label on the inside of the charger indicating its output voltage and output current. You can know it at a glance.

Should you fully discharge NiMH batteries?
