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.
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.

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.
