How Long does a LiPo Battery for RC Cars Last?

LiPo batteries come with a lot of advantages but it has a shorter lifespan if compared to the nickel batteries. A LiPo battery may last typically fr about 150-300 cycles that totally depends on how it is cared for. Just when you will start using your battery frequently, charging and discharging it, it will ultimately be losing its capacity. You take your battery of 1300 mAH out of the box, but it will drop upto 75%, menaing about 1000 mAH.

A 1000 mAH battery bearing a load of 500 mAH will last for about 2 hours. Similarly, if your load is 2000 mAH then it would only last for 30 minutes. A 5000 mAH battery is quoted to last for about 20-25 minutes depending on the driving speed and your driving habits.

However, there are several methods that you can do for making our battery last longer. It includes the usage of proper charge voltage and balanced charging. Do, all the things that are necessary for maintaining the LiPo batteries for RC cars and you will definitely be treated with good and satisfactory outcomes.

How do you Care for your LiPo Battery for RC Cars?

Generally, good care and maintenance are required for LiPo batteries as they are a little too sensitive demanding some extra attention and care. But you can just ignore them for the fact that they need care because they are giving you a bundle of pros as well, including the lighter weight, higher capacities, higher discharge rates, and much more.

Here are some of the tips that will lead you to a better performance of LiPo batteries of RC cars.

Compatible Charger

Not just for increasing the lifespan, compatible chargers for LiPo batteries are the first thing that should be taken care of. If you are using a non-compatible charger you are not fully charging your battery, increasing the safety risks, and also contributing to shortening the life of the battery.

Effective Charging

It is advised to not over-discharge your battery and store the battery fully charged. do not overcharge your battery past 4.2 V per cell. Using a compatible charger will also help you in keeping the voltage and current same until it reaches the peak. Make sure to charge it as per instructions. Don't charge them at below freezing point or near the flammable surfaces. Also, ensure that your battery is not damaged, broken, or swollen.

Discharging

Do not discharge your batteries more than amperage rates specified on the labels. Discharging the battery low than 3V can lead you to some consequences. Also, ensure that your battery doesn't exceed the temperature of 140F during the discharging process.

Storage

Extra Care and attention are needed even in the storage of LiPo batteries. If you are storing your battery fr more than 30 days or planning to leave it as it is for a month or so, do not leave your battery fully charged. Make sure that you are not storing loose batteries together. It’s also recommended that you should not store your battery at extreme temperatures, near the flammable surfaces or in the direct sunlight. Always disconnect the batteries that are not in use and store them in a non-conductive fireproof container as it is really necessary to prevent any unwanted consequences. Improper storage is the most common problem that occurs with LiPo batteries.

Disposal

It's really important to dispose of the LiPo battery properly as it can be a hazard. If you are having a bad day with LiPo batteries then dispose of them in the bins after completely discharging them, and checking the voltage of them. Place the LiPo in a saltwater bath and it will short out the battery, then check the voltage and then dispose them of.

General Care

Don't disassemble the cells, never dispose of them in fire or use them near flammable surfaces, avoiding the opening and deforming of cell, avoiding them to not get hit or bend or striking them with sharp edges are a part of some general care that should be don while handling the LiPo batteries for RC cars. You can also use a fire-resistant container to keep your batteries and yourself safe and sound.

Drone Delivery

Work cited: Grepow news — Drone Delivery

There have been some exciting announcements in the world of drone deliveries lately. The announcements come more from the FAA than from the tech companies, as there have finally been drone deliveries in the United States.

Is this the beginning of crowded skies delivering our food, drone parts and new socks, or is this just a fad? You and I know drone deliveries can be a sustainable technology, and obviously companies like Amazon, Google and USPS think the same.

The pros and cons of drone delivery are worth our attention.

What is Drone Delivery?

Delivery drones are unmanned aerial vehicles (UAVs) that can deliver lightweight packages. Drones generally use 4-8 propellers and rechargeable batteries to provide thrust and attach packages underneath the body of the drone.

Delivery drones are operated autonomously or remotely with operators potentially overseeing multiple drones at once. Delivery drones are used for medical goods, food, retail, or even deliveries that can be difficult to achieve through more traditional vehicle-based services.

Possible benefits of drone delivery

The purpose of a delivery drone is to provide services for delivering objects or commodities rapidly and in hard-to-reach or out-of-the-way locations. They can deliver products quickly to virtually any location.

Drone delivery companies can save money on shipping costs, which would in turn reduce costs for consumers.  Furthermore, a drone would not add to roadway congestion due to less vehicle miles traveled (VMT), and there would be improved safety for the driver of the vehicle.

Consumers would also receive their packages far more quickly and reliably, which would build consumer trust and encourage repeat purchasing.

Possible Limitations of drone delivery:

Drone Battery Life

One of the limiting factors for drone delivery has been battery life. High-quality drones usually can stay in the air for about 30 minutes, and the longer a drone has to recharge, the less packages a fleet can deliver.

Expenses

The cost of adding delivery drones to a company’s services requires a significant investment in the infrastructure of the organization. That’s why there are only a few large businesses that consider using this technology at present. The average price of a drone that can accurately make a delivery can be up to $500.

Privacy risk

Streaming videos to headquarters would allow supervisors to know if a delivery was successfully completed. This technology could help to lessen the risk of theft in the future as well, but there are privacy concerns as drones would likely use GPS and cameras to find homes and deliver packages.

Uncertainty

Irregular and/or unpredictable events, such as weather, wildlife, or vandalism/sabotage, could bring down a drone during a delivery, which could potentially become a safety hazard for those on the ground and/or adversely impact the reliability of drones.

Others

Limited payloads prevent heavier or larger items from being delivered via drone, and designated drop-off locations may become difficult to determine in dense, urban areas.

These are all factors that need to be considered when operating drones for delivery.

Conclusion

It’s just a matter of time until drones have the potential to eliminate the challenges people face every day. Drone delivery is inevitable: when regulations loosen up and the infrastructure is in place, we should expect to see drone deliveries for a variety of purposes. Drones could enable a step change in the availability of everyday items.

Using Spray Drones To Fight COVID-19

COVID-19, otherwise known as the Coronavirus or 2019-nCov, has rapidly expanded around the globe, and health officials and researchers are working hard to understand and prevent the pandemic from spreading further. In order to slow the spread of the infection, many countries have taken tough containment measures, such as instilling stay-at-home or shelter-in-place orders.

Some have even used UAVs to combat the pandemic: Spain, for instance, was the first European country to implement an agricultural drone to spray disinfectant in large, public areas.  More recently, French company Flying Eye also used a DJI drone to do the same especially in urban spaces.

In this article, we will cover what operating personnel should pay attention to when they disinfect public areas around them.

For Operating Personnel

WHO (World Health Organization) says that COVID-19 can spread from people who already have the virus, and it “spreads primarily from person to person through small droplets from the nose or mouth, which are expelled when a person with COVID-19 coughs, sneezes, or speaks.”  To minimize contact with others, personnel should keep at least 1 meter, or 3 feet, from each other.

While disinfecting, avoid smoking, eating, or drinking of any kind.

Personnel should protect themselves by wearing disposable clothing, such as caps and gloves.  Overalls, protective goggles, work shoes, rubber or waterproof boots are recommended as well.

Personnel should wear masks while on duty. WHO also says that wearing a mask “can limit the spread of certain respiratory viral diseases, including COVID-19.” If the mask is deformed, wet or dirty in any way, it should be replaced with another one.

The Flight Area

Permission from local governmental departments should be obtained in advance so as not to violate the regulations in place.

Since disinfectants have a certain corrosiveness, clear the space that will be disinfected and move all people and animals to avoid accidents.  Food and clothing that is not being worn should be put away in advance as well.

To minimize repeated spraying and leakage, plan out the flight area and path in advance.

During the flight, the pilot should always pay attention to any obstacles, keep the flight interval with obstacles at all times, and ensure the safety of flight equipment and property.

Maintenance

After spraying, it is necessary to clean the aircraft and the spraying system because the residual disinfectant can corrode the aircraft, metal structure, water pumps, sprinkler heads, and pipelines, which will affect the service life. Moreover, if the water pump or sprinkler head is blocked, the spray flow will not work quite as efficiently the next time it is used.

About the maintenance of drone batteries, ensure that the voltage difference is less than 0.2V, and charge the battery with a small current to balance the voltage difference. Do not discharge the battery if the voltage is abnormal. The battery should maintain about 3.85V when put into storage, and keep a regular charge-discharge maintenance every month or at least every three months.

Why Refer High Voltage Batteries?

Drones are being used more and more widely in all our lives, so the batteries that power these devices are increasingly advancing and being pushed to their limits. One of the biggest challenges to these batteries is endurance; more and more users need the power to last longer.

One such example is with an agricultural drone. Let’s say that the drone carries 10kg of pesticide with two ordinary Lithium Polymer (LiPo) batteries that have a capacity of 16000mAh in 6S (22.2V). This drone will only be able to last about ten minutes with these batteries, which farmers generally find to be too short. However, the use of high-voltage batteries with the same capacity and C rating can increase this flight time by 15-25%, which will increase the efficiency and operations.

We will explore why high-voltage batteries can improve flight duration and also look at the advantages of such batteries.

1. Weight

Without an increase in weight, high-voltage batteries provide better performance.  This is key for UAVs since each drone has a specific payload that it cannot go over.

2. Higher Voltage

If we compare ordinary LiPo batteries to that of those with high voltage, we see a subtle change in voltage. Through this little voltage increase, users are able to get increased performance in their products.

Ordinary LiPo Batteries

The nominal voltage for a single LiPo cell is 3.7V. A 6S battery pack has a nominal voltage of 22.2V, and a 12S has 44.4V.

A single LiPo cell that is fully charged has 4.2V while a 6S has 25.2V and a 12S 50.4V.

High-Voltage LiPo Batteries

The nominal voltage of a single high-voltage LiPo cell is 3.8V, a 6S pack has 22.8V, and a 12S has 45.6V.

A single LiPo cell that is fully charged has 4.35V while a 6S has 26.1V and a 12S 52.2V.

3. Better Cycle Life

In the chart above, we can follow the discharge rate of several batteries. The high-voltage 4.4V batteries (shown in green) demonstrate a higher discharge rate and discharge capacity.

The above chart shows that, under the same discharge currents and cycles, the 4.4V (in blue) has a longer cycle life than the other batteries at 4.35V or 4.2V.

4. Increased Efficiency

Similar to the example offered at the beginning, we put two drones together for a simple test.  Both drones carried 15kg of water with two batteries of 25C and 22000mAh in 6S.

The drone with the non-high-voltage batteries (22.2V) lasted 17 minutes and 50 seconds.

The drone with the high-voltage batteries (22.8V) lasted longer for 22 minutes and 10 seconds, lasting 4 minutes longer than the ordinary batteries.

Conclusion

According to the above data, the advantages of high-voltage UAV batteries are obvious.
