Electric Bike (Ebike) Range Calculator (2023 Updated). 72 volt bike battery

Introduction: Electric Bike (Ebike) Range Calculator

One of the most common questions we get is how to calculate the geographic range of an electric bike. Basically,

• How far will my ebike go before it runs out of battery power?
• What is the range of my ebike?
• How far can I go per charge?

There are many factors that affect an electric bike’s range, including the type of bike you’re riding, as well as the battery capacity, terrain, and the level of pedaling effort you as the rider put in.

If you have a Bosch motor system, then you should probably use the Bosch ebike distance calculator. But for all other ebikes, our Range Calculator is the most sophisticated online today.

The truth is that most ebikes come with a Bafang motor system or its equivalent, since they are the largest ebike motor manufacturer in the world, and have an exceptional reputation. Our ebike range calculator has been designed based on the performance of the Bafang electric bike system.

For a more precise estimate of electric bike range, we have developed a detailed ebike range calculator which has 16 Separate Inputs and Over 100 Variants. Try it now, and start keeping track of your actual range to help us refine the system. If you want to learn all the details about how far electric bikes can go, and how to get the most range from your ebike battery, skip the calculator and continue reading the rest of this article.

Ebike Battery Myth Busting

First, a little electric bike battery myth busting is in order. Every ebike manufacturer should provide detailed specifications for the battery and every other component on the models they bring to market. Many will also provide estimated ranges, but rarely indicate how these range estimates were derived. That is why we built this calculator, so that you could get a fairly precise range based on your ebike specifications and riding conditions.

Estimated ranges provided by ebike brands aren’t based on rigorous testing

Next, let’s dismiss another obvious falsehood. All ebikes can be ridden like conventional bikes, simply by pedaling and using the standard gears. If the electric vehicle you’re looking at does not have operable pedals, it’s not an electric bike.

If you ride your ebike with the electronics turned off, there is no loss of battery charge. And if you ride your ebike without turning on electronics, there is no drag or resistance from the turned-off ebike motor.

There is no drag or resistance from the turned-off motor

That being said, ebikes do tend to be heavier than standard bikes, due to the added weight of the motor, battery and controller. But there are also lightweight ebikes that fold up and are highly portable.

The lithium-ion battery is the fuel tank for your ebike, not unlike the batteries that power your cell phone and laptop computer. In the olden days a few years ago, some legacy ebike brands would use sealed lead acid (SLA) batteries on their ebikes.

You can still find these types of batteries in cars and on mobility scooters. But with improvements in battery technology, the denser and more energy efficient lithium-ion battery has been adopted as the standard for all ebikes. These batteries will vary in their chemistry, as well as their operating voltage and capacity. Do not get a bike that does not have a lithium battery pack. Find out more about electric bike batteries at our Ebike Battery FAQ.

Like the lithium batteries powering your personal electronic devices, ebike batteries will not last forever. After about 1,000 charge cycles, you will notice that the battery is not holding a full charge. For the average rider, it takes about 2-4 years to charge and discharge an ebike battery 1,000 times. These timeframes could be greatly reduced if you expose your electric bike battery to extremes in heat or cold. So it’s best not to leave your battery in the trunk of a hot car, or in a garage that might reach freezing temperatures overnight.

When you finally need to get a new battery for your ebike, have no fear. Usually replacement or spare batteries are available from the original manufacturer, but even if they are not, there are reputable 3rd party battery companies that can provide a high-quality replacement. Our go-to favorite company for this is the Ebike Marketplace in Las Vegas.

Non-Electrical Factors that Affect Electric Bike Range

There are many variables that affect ebike range, including the bike design of bike, rider weight and riding style, terrain, weather, surface moisture, tire inflation.

Bike Design Maintenance. Electric bikes, like conventional bikes, come in many flavors. You have fat tire mountain ebikes, small folding ebikes, and laid back cruiser style ebikes. There are several key factors in bike design that affect range.

First, the weight of the bike is a major factor, but also the width of the tires. Fat tires, for example, have more surface area in contact with the ground, and more traction (friction) compared to a road bike with narrower tires. This adds resistance which can deplete energy reserves more quickly.

Second, it’s important to note that a poorly tuned or maintained ebike will have a shorter range than a properly maintained vehicle. Low tire inflation, poorly aligned gears and brakes, and high wind resistance due to a lack of aerodynamic design will all contribute to reducing the range of an ebike.

Payload. The weight of the passenger and any cargo will also have a dramatic effect on ebike range. All things being equal, a 225-pound rider with a fully-loaded trailer will place a much higher demand on the battery than a 125-pound teenager with a fanny pack. The distribution of the payload on the bike will also affect range, especially if a bike is unbalanced due to heavy loads placed on the rear rack.

Weather Terrain. Headwinds and wet roads each will reduce the potential range of an ebike. Likewise, how hilly your ride is, and if you go off-road on gravelly trails will impact how far you can travel on a single charge.

Electrical Factors that Affect Ebike Range

All electric bikes have 3 essential components that set them apart from conventional bikes. These are the motor, the controller and the battery. Each of these electrical components plays a critical role in the performance of an electrical bike, and if any of them are not working properly, it can adversely affect your ebike performance range.

If you struggle with the concept of electrons running through wires to power a motor, you’re not alone. Check out the Water Pipe Analogy graphic below.

We use watt-hours to measure the energy capacity of a battery pack, and this will help you figure out how long you can ride your ebike before fully discharging the battery. But before we get into watt-hours (symbolized Wh), let’s first review what a watt itself is.

A watt (W) is a unit of power, and power is the rate at which energy is produced or consumed. Think of watts as a measure of electrical flow. Does an electrical device need a big flow or a small flow to work? For example, a 100W light bulb uses energy at a higher rate than a 60W bulb; this means that the 100W light bulb needs a bigger “flow” to work. Likewise, the rate at which your solar energy system “flows” power into your home is measured in watts.

A watt-hour (Wh) is a unit of energy equivalent to one watt (1W) of power expended for one hour (1h) of time. A watt-hour is a way to measure the amount of work performed or generated. Household appliances and other electrical devices perform “work” and that requires energy in the form of electricity. Utilities typically charge you for electrical energy by the kilowatt-hour (kWh), which is equal to 1,000 watt-hours.

An ebike battery is measured by its voltage (V) and amp-hour (Ah) rating. To calculate the Wh of an ebike battery pack, we simply multiply its V and Ah to get the Wh.

• A battery rated at 36 V and 10.4 Ah will have a 417.6 Wh capacity (36 x 10.4 = 374.4), like on the Eunorau UHVO All-Terrain Ebike
• A battery rated at 48 V and 21 Ah will have a 1,008 Wh capacity (48 x 21 = 1,008), like on the Bakcou Mule.

How Long Does it Take to Charge a 72V E-Bike Battery?

72-volt batteries are mostly used in higher-wattage electric bikes such as 2000w or 3000w ebikes as they are very powerful and easily supply the demand for power to the motor while riding on rugged and long terrain effortlessly.

But the problem is how long to charge a 72v ebike battery in order to get the best performance and prolong the battery life. Don’t worry!

I have come up with a detailed article on the charging time for a 72V ebike battery, how the time differs from one battery model to another (36-volt or 48-volt), and how the battery technology is growing overall.

For attaining more clarity, we have also answered the top 3 FAQs about e-bike battery charging.

If you have a 52-volt battery in your ebike, learn how long to charge your 52v electric bike battery in order to maintain its health.

Charging Methods for a 72V E-Bike Battery

How long it takes to charge a 72V ebike battery is influenced by various factors but the charging method is one of the primary ones. Whether you are using an AC, DC, or solar charger does signify the amount of time it will require to fully charge your battery.

However, it is important to take into consideration that the charging time depends as much on the condition of the battery, the temperature, and the charging profile of the charger.

Nevertheless, let’s see how the use of different charging methods can lead to different charging times for your 72V electric bike battery and also draw a comparison to see which method saves you the most time.

AC ChargerDC ChargerSolar Chargers

It is a common charging method that can be simply plugged a standard wall outlet for powering the battery which makes it easy to find outlets on long rides.	DC chargers are not that preferred since they require a dedicated power source which can be expensive.	Solar chargers use photovoltaic panels to convert sunlight into electricity to charge the battery.
The charging time for a 72V 20Ah battery is usually 6 to 8 hours.	It is expensive, but they do charge way faster than AC chargers. It takes only 1 to 2 hours to fully charge a 72V 20Ah e-bike battery.	Solar chargers naturally take way longer than both AC or DC chargers to fully charge a 72V e-bike battery, depending on the amount of sunlight available.
The bright side is that AC chargers usually come along with the battery and can be carried along on your riders.	It is not always possible to carry DC chargers and is usually not easy to find everywhere.	Having said that solar chargers are the best option for charging your e-bike in remote areas on your long rides.

How Long to Charge a 72V Ebike Battery?

Keeping all the factors in mind, a 72v 30Ah lithium-ion battery takes a minimum of 5 hours if it is charged with a 6 amp charger. Because the charger output power and battery capacity play a very important role in charging time.

Let’s know how I calculated the charging time for a 72V ebike battery,

Charging Time = / Charger Amps

Generally, a charger for a 72v ebike battery is of 5 amp to 8 amps. If you charge your 72v 30Ah battery with a higher-amp charger, charging duration will reduce and vise-versa.

One more important point to consider while charging an ebike battery is that the last 10% charge level takes more time compared to the initial charging time.

There are different types of batteries that influence charging time so let’s learn in detail how a battery type influences charging time.

Note: If you have a 60-volt battery in your ebike, learn how long to charge your 60v e-bike battery in order to extend its lifespan.

Charging Time of Different 72V E-Bikes Batteries

The charging time of a 72V e-bike battery varies from one factor to another for example the battery capacity and the charger capacity. Similarly, one such factor is the battery model of your e-bike.

The battery model is important because it determines the battery’s performance characteristics, including its voltage, capacity, and energy density. It also determines the size and shape of the battery, which can affect its compatibility with different devices and applications.

It’s important to choose the right battery model for a particular device to ensure that it operates safely and efficiently. Hence, let’s look at the best-suited battery models for your 72V e-bike battery and their respective charging times.

Charging time for 72v Lithium-ion batteries

Lithium-ion batteries are a popular choice for electric bikes due to their high energy density, long cycle life, and low self-discharge rate. They are also relatively lightweight and compact compared to other battery types.

Some popular Li-ion battery models for 72V e-bikes include Samsung INR18650-20S, LG MJ1, and Panasonic NCR18650GA, these take somewhere around 6 to 8 hours to fully charge a 72V 20Ah battery. Charging time increases if with the increase of AH.

Charging time for 72v LiFePO4 batteries

It is a 72V e-bike battery that uses LiFePO4 (Lithium Iron Phosphate) cells, which are known for their safety and long cycle life.

This battery is designed for e-bikes that require a high level of safety and reliability since it has a built Battery Management System (BMS). And the charging time taken is between 2 to 4 hours.

Charging duration for 72v Lishen batteries

This is another type of 72V e-bike battery that uses Lishen cells, which are known for their high energy density and long cycle life after lithium. This battery is designed for high-performance e-bikes that require a lot of power and takes around 6 to 7 hours to fully charge.

Common Charging Issues with 72V Electric Bike Battery

There could be several common charging issues with 72V e-bike batteries. If you face any of the below-mentioned charging issues with your 72V e-bike battery, then it is important that you immediately stop using both the battery and charger and seek help from a professional.

Here are a few possible ebike charging issues and their potential causes:

The battery not charging at all

It could be an issue with the charger, the charging cable, or the battery itself. You can check in order to make sure you are not operating a damaged cell or a dead battery in your ebike.

Battery charging slowly

The reason for this could be a low-powered charger or a problem with the charging cable. What you can do to solve this issue is to make sure you are using the recommended charger and that the charging cable is not damaged or frayed.

Battery not holding charge

When there’s an issue with the BMS or one or more of the battery cells, your battery might struggle to hold the charge. This issue often is a result of overcharging or deep discharging of the battery, damaging the battery cells over time.

Charger getting hot

Often when you are using a faulty charger, the battery tends to heat up more essentially damaging both the charger and its battery.

We highly recommend taking advice from the manufacturer to diagnose the faced issues and provide appropriate solutions to get your e-bike battery charging and performing correctly again otherwise it may catch fire or even explode. Read our guide on why ebike batteries catch fire.

Future of Ebike Batteries Charging Technology

The future of e-bike batteries and charging technology looks quite promising as advances in technology continue to make e-bikes more efficient, powerful, and accessible.

Let’s see what are the potential trends and developments in e-bike batteries and charging technology.

Increased energy density

E-Bike batteries with higher energy density will be able to provide more power and range, advances in battery chemistry and manufacturing techniques make the idea of higher density a reality.

One of the biggest drawbacks of e-bikes has been the relatively long charging times required to fully recharge the battery. However, new fast-charging technologies are being developed that will allow riders to recharge the e-bikes much more conveniently and faster.

Wireless charging

This technology is already being used in some consumer electronics, and it is expected to become more common in e-bike batteries as well.

Integration with Smart homes and grids

As more homes and communities are becoming more and more “Smart”, E-bike batteries could be integrated with these systems to provide more efficient and sustainable energy use.

For example, an e-bike battery could be charged using solar panels or wind turbines to power homes during peak energy demand times.

If you have a 48v battery in your electric bike, you must know an ideal charging time for a 48-volt ebike battery to maximize the battery life

Conclusion on The Charging Time for a 72V Ebike Battery

There is rarely anyone present who would refuse to switch to a higher voltage battery, especially for e-bikes since all riders look for that extra energy push during those uphill trails.

However, they want to use high-voltage e-bike batteries that come with maintenance, cost a lot of dollars, and comparatively more charging time.

But we have seen amongst riders that when used accurately with the right appliances like charging cables and methods, a 72V e-bike battery is highly effective in terms of charging time.

Hope our summarization on how long to charge a 72v ebike battery helps you, Keep riding!

Frequently Asked Questions

What is the voltage of a fully charged 72-volt battery?

Each type of battery has more actual voltage than the nominal voltage when it is fully charged. For e.g, a fully charged 72-volt lithium-ion battery has a voltage of around 83 volts. Whereas a fully charged 72v lead-acid battery has around 81 volts.

What voltage charger to use to charge a 72v ebike battery?

Most brands recommend charging a 72v battery with at least a 5 amp charger as it neither charges the battery fast nor slow. If you increase the charger amp, will save you time but may affect the battery’s life.

What wattage ebike is 72v battery perfect for?

There are two aspects of a battery to consider while selecting the motor wattage i.e., Voltage and Amp-hours. Basically, a 72-volt battery is very powerful, mostly used in ebikes having a minimum rating of the motor is 2000-watts.

What is the range of a 72v 20AH lithium-ion battery?

The range of a battery depends on the motor’s output power (how many watts does an ebike consume to cover one mile). Generally, a 72v 20 Ah battery has a range of around 80-100 miles. It may vary on the basis of bike speed, load, road conditions, etc.

Long-Range e-Bikes. How Far Can I Go on a Single Charge?

No matter what you choose to call it or how you write it. E bike. Electric bicycle. eBike. Electric bike. E-bike. One thing is certain. The eBike is disrupting the transportation sector in a big way. and more people are buying and commuting on an electric bike than ever before. One of the biggest considerations when buying an e bike is range. How far can the eBike I’m interested in actually go?

The longest range e bike currently on the market is from Delfast bikes. It holds the Guinness World Record for longest range eBike on a single charge. 228 miles. With upgraded software on the newest model, the Top 3.0i just achieved an unheard of 232 miles. But how many miles can an electric bike go in real world conditions? Can you get an idea of how many miles an electric bike can go based on the volts and amp hours a company lists on their website?

The battery, controller, motor, and various components all contribute to the range you can achieve. Together they determine your speed, the amount of pedal assist to apply, and can even give you an estimated range based on those factors. With that said, the number one factor for that question of how many miles can an electric bike go comes down to the battery capacity. Volts, Watts, and Amp Hours.

The Voltage of the Battery

The first characteristic to pay attention to is the voltage of the battery. This parameter is commonly expressed in Volts (V). Most electric bike companies utilize a 36V or 48V battery. In most cases, these mass-produced batteries have a relatively low cost. However, as with many other technological products, you get what you pay for. A lower voltage battery will not provide the range many riders are chasing.

An electric bike equipped with a 36V/48V battery delivers modest power to assist the cyclists pedaling. In uphill terrain the rider may notice a lack of power. Speed is also modest with this type of battery. If you want an electric bike that is powerful and fast, it’s best to aim at models equipped with higher voltage batteries.

Electric bikes with 52V batteries are significantly more powerful, faster, and more efficient. Efficiency is important in achieving a longer range. However, as we will discuss later, other parameters determine the range of an e-bike. 52V batteries are also expensive, but the higher the voltage the more enjoyable your ride will be thanks to the power and speed available.

It is wise to invest upfront in an electric bike with an electric system based on a high-voltage battery. Delfast utilizes a 72V Lithium-ion battery on our high-end TOP 3.0i electric bike. The use of a 72V battery makes the Delfast e-bike the fastest in the world. The size of the battery allows for more power with the use of a 3,000W motor. Of course, it is also the longest-range e-bike.

The Amp-Hours Value of a Battery

If the voltage of the battery defines the speed and power of an electric bicycle, what is the definitive aspect of the range? Here, we have to use a different parameter often referred to as Amp-Hours (Ah).

When the motor is functioning, it draws an electric current from the battery. It is measured in Amperes (Amps or A) and refers to the flux of electrons in the motor coils. The higher the Amp value, the more intense the flux of electrons is. Both voltage and current define the power of the motor since power in Watts (W) is equal to voltage times amperes.

The Amp-Hours value refers to the fixed number of Amperes that the battery can sustain during an hour. Typical values go from 10Ah to 20Ah. So, this is also a measure of the battery capacity. A battery with a 10Ah capacity can sustain 20A in half an hour or 5A in 2 hours. The larger the capacity, the longer the electric bike will be able to ride on a single charge.

Batteries for Long-Range e-Bikes

As seen, a long-range electric bike must use a battery with a high capacity. This is easier said than done. High-capacity batteries are larger and significantly heavier. Typical Lithium-ion batteries weighing 6-8lbs deliver a range of approximately 20 miles. That’s not exactly a long-range electric bike. If your electric bike is equipped with a throttle only mode, riding without pedaling will further shorten the range.

A long-range e-bike is usually equipped with a battery of at least 20Ah and 52V, which allows for a range of approximately 100 miles with a motor of 1,000W. New eBike riders should select the battery with the highest voltage and capacity possible within their price range. There are three important factors to consider:

• Size. High-capacity e-bike batteries are larger and more cumbersome. Be sure your frame and bike of choice can accommodate it.
• Weight. High-capacity batteries are heavier. If you need to carry your e-bike upstairs this is an important consideration.
• Price. High-capacity batteries are more expensive. Depending on the intended use of your electric bike, a high-capacity battery may not be a must. If your planned use is only for commuting, you can estimate the distance of a daily round trip. If it’s a modest commute, you can use a conventional battery with a capacity between 10Ah and 20Ah.
