The battery can be said to be the most important component of an electric bicycle. As a new or prospective electric bicycle user, we believe you have already realized the importance of an electric bicycle battery. However, most electric bicycle users have a common question: How do you choose the right battery for your electric bicycle? How do you know which one is the best among all available battery types? What type of battery should I buy for my electric bicycle?



In this guide, we will answer all the questions that trouble you. The article also contains information about different types of electric bicycle batteries available for you to use. Additionally, we will enlighten you about the factors to consider before choosing an electric bicycle battery. Keep reading to learn how to select the best battery for your electric bicycle.


Basic Electric Bicycle Battery Terminology:


Before choosing the best battery for your electric bicycle, you must be able to understand the terminology used to describe electric bicycle batteries. We will define some terms that will help you have a better understanding of batteries.




Here is a list of commonly used terms when discussing electric bicycle batteries:



Ampere (Amp)

Ampere-Hour (Ah)

Voltage (Volt)

Watt (W)

Watt-Hour (Wh)



Ampere (Amp):
This is the unit of electric current. It is an internationally recognized standard unit. You can compare amperes to the size or diameter of a pipe through which water flows. This means that more amperes indicate a larger pipe with more water flowing per second.



Ampere-Hour (Ah):
This is the unit of charge, and it represents the relationship between electric current and time. It is a measure of battery capacity. A battery with approximately 15Ah can discharge continuously at 1.5A for ten (10) hours or at 15A for one hour.



Voltage (Volt):
This is commonly referred to as volts. It is the static electric potential difference between two (2) conductors, the live conductor and the neutral conductor. The optimal voltage reading for an electric bicycle battery is 400 volts.



Watt (W):
This is the standard unit of power. The higher the wattage, the higher the power output of the electric bicycle. Additionally, one (1) watt is equal to one (1) volt multiplied by one (1) ampere.



Watt-Hour (Wh):
This is the unit of power for a given period of time. It measures the total power output over a given time. It does not regulate the power output at a particular moment like watts. Think of it as speed and distance. For example, if your car's speed is measured in watts, then the distance from one place to another is measured in watt-hours. So, if your electric bicycle's battery discharges at a power of 100W for two (2) hours, it has consumed 200Wh.



Nominal voltage is sometimes used to refer to voltage measurements in electric bicycle batteries. This is because each battery cell in a battery can withstand a certain range of voltages.



Now that you have an understanding of the basic terms, we will explain different types of electric bicycle batteries. From the very beginning, the battery has been a determining factor in your enjoyment and value of an electric bicycle. Here is a list of the most common types of electric bicycle batteries in the market.



Battery Types


Lead Acid

Nickel Cadmium

Nickel Metal Hydride

Lithium-ion



Lead Acid Batteries:
Lead acid batteries are known for being very inexpensive. However, they have lower power output and are quite heavy. Compared to other battery types of the same weight and size, they have smaller capacity. Lead acid batteries have three main uses.



They can be used as backup power sources for stationary applications. They also contribute to deep cycle applications such as golf carts, scissor lifts, etc. Finally, they are used as starter batteries for automotive motor systems. They can also be used for electric bicycles. However, their weight and power output mean that we do not recommend their use.



Lead acid batteries are the heaviest among all types of electric bicycle batteries. They are three times heavier than lithium batteries and twice as heavy as nickel batteries. Additionally, lead acid batteries have smaller battery capacity compared to nickel and lithium batteries. The maximum capacity of lead acid batteries is half that of lithium and nickel batteries.



Nickel Cadmium Batteries:
These types of batteries are very durable and can last a long time if properly maintained. Additionally, they offer higher battery capacity compared to lead acid batteries but much less than lithium batteries.



Moreover, nickel cadmium batteries have excellent load performance. They can withstand a great deal of pressure from the throttle.



However, they also have some drawbacks. Their self-discharge rate is quite significant. When fully charged and not in use, the battery level can drop to as low as 70% within 24 hours. Their power density is low as well.



Furthermore, nickel cadmium batteries are expensive, and their main component, cadmium, is a hazardous pollutant. Due to environmental safety and recycling concerns, nickel cadmium batteries are often phased out of the market. These types of batteries are not the right choice for electric bicycles.



Nickel Metal Hydride Batteries:
Nickel metal hydride batteries are an improvement over the previous two battery types—lead acid and nickel cadmium. Even in self-discharge situations, nickel metal hydride batteries can hold 45% more charge than nickel cadmium batteries. However, they lack proper durability. Their maintenance is unstable, and charging can be a complex task.



Even with limited use, nickel metal hydride batteries generate heat quickly. This leads to high self-discharge. While the discharge rate is not as high as nickel cadmium batteries, they are not recommended for electric bicycles.



In terms of range improvement, nickel metal hydride batteries have almost no advantage over nickel cadmium batteries; they are more expensive. Despite this, they are more efficient and productive compared to lead acid and nickel cadmium batteries.



In terms of market share, nickel metal hydride batteries are rapidly losing value due to the presence of lithium-ion batteries. They are considered too expensive and have limited power output. Therefore, they are not the ideal choice for electric bicycles.



Lithium-ion Batteries:
Lithium-ion batteries automatically become the default battery for every electric bicycle in today's market. They power around 90% of electric bicycles on the market. Lithium-ion batteries generate more power output compared to other battery types for their weight. Most importantly, they are more durable and have a longer lifespan.



Furthermore, lithium-ion batteries are primarily divided into three types. These types have some differences, but they have one common aspect: they last longer.



On the other hand, they are compact and require functional electronic components to prevent them from catching fire or self-destructing. However, these are not concerns you should worry about. Manufacturers always have safety mechanisms in place to prevent accidents. However, it is still crucial to understand how to handle and maintain them properly.



Despite the expensive price tag, we recommend purchasing lithium-ion batteries for your electric bicycle. They are the ideal battery type for every electric bicycle in terms of range, weight, lifespan, etc. Here are the three types of lithium-ion batteries.



Lithium Manganese Battery (LiMg204):
This is the newest type of lithium-ion battery. They have good durability and range. Additionally, manufacturers claim that they have a longer lifespan compared to other lithium batteries. You might be interested to know that this battery type is currently used in some hybrid cars.



Lithium Cobalt Battery (LCo):
This is another type of lithium-ion battery. It has been on the market for a longer time compared to lithium manganese batteries. It is believed to have higher energy density compared to other lithium batteries. Additionally, it provides you with the highest power output, is lightweight, and reliable.



Lithium-ion Polymer Batteries (Li-pol)
This type of lithium battery is no different than other lithium-ion batteries in terms of weight, price, and range. Nevertheless, as a polymer, lithium polymers can undergo different moulding processes to bring out fantastic shapes.



They do not contain any liquids and requires less protective battery casing compared to other lithium batteries. This liquid-free feature means they are less vulnerable and provide more stability. Hence, they are ideal for use in low power applications – like electric bikes.



For a pleasant riding experience with your electric bike, we recommend a Lithium-ion battery for you.

Things to look out for before choosing a Lithium-ion Battery
In choosing a lithium battery for your electric bike, you need to consider the voltage and ampere ratings. This is important as it determines the range, durability, and power input of your battery.



Volts and amperes ratings are the two major talking points when choosing the right battery for your electric bike. You should know that selecting the wrong voltage/ampere rating can damage your e-bike or cause a fire outburst.



Voltage
Every electric bike has a unique input volt range. This means you can only power your electric bike with the exact voltage required to power it. You should not power your electric bike with a battery with a voltage that is more or less than the recommended range. This is necessary to avoid complications.



Using a battery with lesser voltage means you will not have enough power to significantly run your bike’s motor system. However, using a higher voltage can damage the sensitive electrical parts of the motor system. Most electric bikes accept nominal voltages – 36 volts or 48 volts. Generally, electric bikes come outfitted with a 18650 cell.



Lithium cobalt battery cells can hold up to 4.3v with a full charge and about 3.1v after discharging.



For example; if your bike has a lithium manganese cell, with a rating of 49volts and 13 cell clusters. Each cluster has an average voltage of 3.8v.



Here is how to calculate the average voltage of your battery;



3.8volts x 13 cells = 49.4volts or 49V average.However, after a full charge; this “49v” average battery will hold 4.3v * 13 cells = 55.9volts. As you discharge the battery, it will reduce every cell to 3.1v from 4.3v – minimum volts of 3.1v * 13 = 40.3v.



This average voltage range will help you determine if this battery is compatible with your bike. Voltages are converted to speed on your electric bike. If you choose a battery with higher voltage ratings within the motor limit, all things being equal, you’ll reach new top speeds.



Amperes

Amperes are virtually the measure of the flow of current at a specific voltage. In reality, the amperes are a measure of your bike’s torque. With more available amperes for your electric bike’s motor system, one thing is sure, more torque.



So, with your 49v 13Ah battery, your electric bike can peak at 68A with a continuous draw of 45A.



However, most motor systems can only pull as much current as they need. Therefore, choosing a battery with a high current output will not damage your electric bike’s motor.



This means if volts are the “speed” in your e-bike, amperes are how fast your electric bike’s battery can deliver this speed. More volts naturally gives more speed. Also, a higher amperage rating means more speed per second or hour. This means the power you get from your electric bike battery will determine your torque.







To sum it all
Choosing the best type of Lithium-ion battery for your electric bike can be complicated. However, lithium cobalt is outstanding, and it offers higher energy density than others. This doesn’t mean other types of Li-ion batteries are bad for your electric bike.



Lithium manganese batteries are more ecologically friendly and safer. Lithium manganese also offers a higher cell voltage than lithium cobalt batteries. However, the energy density of lithium manganese is 20% less than that of lithium cobalt batteries.



Finally, lithium manganese also has extra advantages in terms of lithium-ion chemistry – including higher temperature performance and lower cost. Also, your budget is a big determinant of the kind of Li-ion battery you will buy.



Choosing the best type of battery for your bike is essential. It’s the only way that you will be able to enjoy using your bike without any hiccups. We are available to answer any questions that you may have about electric bike batteries. Contact us today.

The electric bike battery is one of the most important parts of an electric bike and without it the electric bike will turn into a regular bike.With this importance, everyone is trying to get the best performance from the battery in order to increase his enjoyment of the electric bike.



One of the most frequently asked questions: Why is my ebike battery draining so fast? In fact, this question is an important but somewhat confusing question.The reason for this is that the word FAST cannot be measured, meaning the battery drained fast, i.e. some 15 minutes of riding your ebike.





Or drained fast, meaning if you used to use the ebike for 20 miles per one charge, and now you go 15 miles per one charge? That is why in this post we will answer the question Why is my ebike battery draining so fast? from both sides.We will explain the reasons that lead to abnormal battery consumption and also the reasons that reduce the range of a single charge.



So that you have all the information you need to determine the causes of the battery problem and how to repair it.


Why is my ebike battery draining so fast? (the extreme condition reasons)


As a general rule, the battery drains fast as a result of damage to the internal cells of the battery or a problem with the BMS.



1-Damage Cell or Group of Cells.



The first and main reason why the electric bike battery drains fast is that there is damage to a cell or group of cells inside the battery, and the reason for this is that when there is a damaged battery cell the voltage becomes lower than normal, so the BMS “battery management system” completely shuts down the battery to save the internal cells of the battery.



To understand this point better, let’s take a quick look at how the BMS works.



How the BMS works:



Inside the battery of your electric bike are cells grouped together and each group is connected in series and connected to the BMS.

Through this connection, the BMS measures the voltage coming out of each group.



BMS is programmed to a minimum voltage & when the battery cells reach it, the BMS turns off the full battery completely.



Based on this, if you have only one cell or a group of cells damaged, you will find that the battery drains very fast.

In order to solve this problem, the damaged cell must be identified by measuring the voltage for each group of cells using a voltmeter






2-BMS Problem.



The second reason that may lead to the battery draining quickly is that there is a problem with the BMS unit itself.

The reason for this is that the BMS, as we mentioned, is the controller of the battery, so if there is a problem with the BMS and it is unable to read the battery cell voltage correctly, It will cause the battery to shut down quickly and you will notice that the battery is drained abnormally.



To solve this problem, you can reset the BMS or replace the BMS. You can see this post to learn the correct ways to do REST for BMS

Why is my ebike battery draining so fast? (The reasons for the low mileage)



In this part of the post, we will explain the most important reasons that reduce the miles you travel with your electric bike on a single charge.



1-Using Super Fast Charger.



One of the reasons that reduce the performance of the battery in general and reduce the long term is the use of a very fast charger because this will strain the battery cells and reduce their lifespan.



Based on my personal experience, I have noticed that the number of miles I travel when charging my bike battery with the original charger is more than the miles I travel when I use the fast charger.



Of course, you will need to use a fast charger in some situations, such as you need to charge on the go in case you are away from home,but do not make the fast charger your first option.



You can check out this post to learn how to choose a fast charger that is suitable for your bike battery.



2-Wrong storage habit.



When storing your electric bike battery, you should follow the rules that help maintain the life span of the internal cells and or these rules are to keep the charge rate around 75%.



We wrote this post that explains the best steps that you can take to maintain your bike battery during storage.



3-Using throttle only.



When you rely only on the throttle while riding your ebike, this will lead to the battery draining fast because you are making the bike do all the work.

This will lead to the fact that the motor will need to consume a lot of watts, which will reduce the range of a single charge.



4-Going uphills too much



When you use an electric bike up a steep hill, it takes a lot of the bike motor to give you the right torque to go up the hill.

This will also increase the battery drain and reduce the range of a single charge.

5- Riding in hot weather.



When you ride your electric bike in very hot weather, this will affect the movement of ions inside cells, which makes the chemical processes that occur inside the cell difficult.



This will greatly reduce the duration of a single charge and generally, most high-quality BMS will shut down the battery if the internal temperature of the battery reaches a certain degree.



6-Loading a Lot of staff.



Another reason for the battery depleting quickly is loading many things on the bike or towing a trailer.

This will lead to an increase in pressure on the motor to produce the highest torque, which will increase the battery consumption and thus reduce the battery range.



Conclusion


The reason for fast battery draining (30 minutes or less) are often due to damage to some battery cells or a malfunction in the battery management system BMS



On the other hand, there are several reasons that lead to the battery draining faster than normal, including the frequent use of a fast charger that is not commensurate with the capacity of the battery, improper storage of the battery, loading heavy things on the bike, and riding the bike in very hot weather.

Also, the continuous use of throttle only while riding and riding uphills a lot.

The electric bike battery is one of the most important components as it transforms an ordinary bicycle into an electric one. On the other hand, it is also considered one of the most expensive parts of an electric bike, with prices ranging from $500 to $1000 for certain models.

Now, the question arises: Can electric bike batteries be repaired? Considering the cost of the battery and its significance to electric bike riders, it is a logical question to ask.




Can electric bike batteries be repaired?


Generally speaking, electric bike batteries can be repaired since their main components, such as the battery cells, BMS board, and wiring, can be easily replaced. Based on this, the battery can be repaired by changing these components.



Now let's discuss the most significant issues that can occur with electric bike batteries, their symptoms, and the possible solutions.



1.BMS Board Issues


The Battery Management System (BMS) is responsible for protecting the battery by regulating the flow of current into and out of the battery.

To understand how it works in practice, the BMS board is connected to all the cells in the battery and measures their individual capacities. When one cell discharges, the BMS completely shuts down the battery to prevent any potential damage.

From the functioning of the BMS, it becomes evident that charging or discharging is controlled by the BMS.



Therefore, if you find that the battery has some remaining charge but is unable to charge or discharge, it indicates a problem with the BMS.



How to solve the BMS Problems


To resolve BMS issues, there are generally two methods: resetting and replacing (I personally prefer replacement since BMS prices are not expensive either).



To reset the BMS, you can follow these steps:


1. Remove the outer cover of the battery.

2. Disconnect the cables connected to the BMS of the battery.

3. Connect the battery to the charger and start charging.

4. During charging, reconnect the BMS cables.

By performing the above steps, the BMS will be reset to its default settings.


Replacing the BMS Board.


BMS Main Cables

There are three main cables connected to the BMS:



(P-) cable is responsible for negative discharge to the connector.



(C-) cable is responsible for negative charging to the connector.



(B-) cable is responsible for the battery's negative terminal connection.



Tools Required:

Screwdriver

Soldering iron





Steps for replacing the BMS board:


1. Remove the outer cover of the battery.

2. Desolder the three main cables of the BMS.

3. Disconnect the connector connected to the battery.

4. Install the new BMS in the same position.

5. Resolder the main cables.

6. Connect the connector back to the battery.

7. Test the battery's charging.

If everything goes smoothly, reassemble the battery cover.



Important Note: In most cases, BMS damage is caused by faulty battery cells inside the battery. Therefore, it is advisable to measure the voltage of all the cells before reassembling the battery cover to ensure that all the cells are functioning properly.



2. Damage to One or More Cells


The second most common cause of electric bike battery failure is damage to one or more cells inside the battery.



In this case, you will be unable to operate the battery at all.



You can identify the damaged cells by individually measuring the voltage of each cell. You will find that most cells have a consistent reading (e.g., 4.1 or 3.8 volts). When you notice a significantly lower reading in a particular cell, that cell is the problem.



There can also be visible signs of battery damage that you can observe with the naked eye, such as the presence of black substances or cuts on the battery casing.



Note: Replacing battery cells requires specialized equipment to ensure the proper functioning of the battery, so it is best to have it done by a professional.



Don't worry, the cost will be minimal since you have already done all the work and identified the defect. All you need is to connect a new battery cell. You won't have to spend too much!



3. Wire Disconnection


The final major cause of battery failure is the presence of cut or disconnected wires inside the battery, whether it's in the main wiring of the battery or in the wires connected to the battery. This will result in the battery ceasing to function.



Usually, this issue occurs due to the battery being dropped or impacted on the ground. If you take good care of your electric bike's battery, you'll be safe from this.



To address this problem, simply remove the outer cover of the battery, locate the cut wires, and reconnect them.



Then, using a voltmeter, measure the voltage of the battery. If you find that the voltage reading is equal to the capacity of the same number of cells, you can determine the battery capacity using this formula (number of cells * 4.2 volts).



Connect the battery to a power source to ensure proper charging, and then close the battery cover.



4. Loose Battery Connection


When the battery is connected to the electric bike, it can cause damage or breakage to the battery pins, resulting in the battery ceasing to function.



You can visually inspect the pins to determine if the issue lies there, and in most cases, the battery will not be properly installed on the bike.



To address this issue, you can try modifying the pins using a screwdriver, but make sure to turn off the battery first.



Alternatively, you can replace the damaged parts within the battery entirely.






5. Charger Malfunction


The reason you are unable to use the battery may be due to a faulty charger rather than a problem with the battery itself. To determine if the issue is with the battery, try charging it with another charger or test the charger itself.



You can refer to this article, which provides detailed explanations on how to test an electric bike battery charger.



Conclusion


In general, electric bike batteries can be repaired by replacing internal cells, the BMS board, or fixing internal wiring.



One of the most significant issues that can occur with electric bike batteries is BMS damage, internal cell damage, or internal wire disconnection. Lastly, the battery pins may be damaged due to improper removal of the battery.
