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.

Based on type and capacity, the weight of electric bicycle batteries can range from 5 pounds to 40 pounds or even heavier. Typical lithium-ion electric bicycle batteries can weigh as light as 5 pounds and go up to 20 pounds. On the other hand, lead-acid electric bicycle batteries are larger in size and heavier, starting from 30 pounds.



The weight of electric bicycle batteries is not randomly determined; factors such as voltage, ampere-hour capacity, anode and cathode materials, and other metal components contribute to the weight.




In simple terms, batteries with higher voltage and larger capacity tend to be heavier, while batteries with lower voltage and smaller capacity are lighter.



Most riders prefer lightweight and maneuverable bicycles. Since it's not possible to reduce the weight of the electric bicycle frame or the weight of the motor and other key components, the only reasonable way to make the bicycle lighter is by adjusting the weight of the battery.



Whether it's an internally integrated frame battery or a simple removable external battery, understanding the weight of the electric bicycle battery and, if possible, replacing it with a lighter battery can help make your electric bicycle lighter.



Comparison of Different Bicycle Weights

Here is a side-by-side comparison of the best lightweight electric bicycles. Hopefully, it will help you find your ideal bicycle.





Types and Weight of Electric Bicycle Batteries


There are various types of electric bicycle batteries, and each type has a different weight value.



We can certainly discuss the weight of internally integrated or externally removable or fixed batteries. However, it would be easier to understand if we categorize the batteries based on their chemistry and material composition.



Lithium-ion Batteries:

Well-made removable internal and external lithium-ion batteries typically weigh around 8 pounds to 17 pounds.



Lead-acid Batteries:

Lead-acid batteries are cheaper but heavier compared to lithium-ion batteries. You would typically find lead-acid batteries weighing between 30 pounds to 40 pounds.



What factors affect the weight of electric bicycle batteries?



Voltage and Capacity:

Electric bicycle batteries are a combination of interconnected batteries. The more batteries there are, the higher the ampere-hour capacity and voltage flow. These batteries have a metallic body along with metal anodes and cathodes, so their weight is definitely noticeable.



Material Composition:

Graphite, nickel, copper, lead or lithium-ion, metal oxides, and zinc—all these battery types have composition components, most of which are metals, making them a significant factor behind the heavyweight batteries.



Are there weight limits for electric bicycles?


Yes, electric bicycles have weight limits. The weight of leisure bicycles typically ranges from 200 pounds to 300 pounds, while cargo/load-carrying bicycles weigh around 450 pounds to 550 pounds.



Please note that weight limits refer to the bike's ability to withstand a certain weight. Therefore, a weight limit of 200 pounds means that your electric bicycle weighing 50 pounds or 60 pounds will be able to comfortably carry around 200 pounds without affecting performance.



Is the weight of your electric bicycle important?



The weight of a bicycle is indeed crucial. A heavy electric bicycle may be reliable and comfortable to ride, but storing or carrying it can be a hassle. If you have to transport a bike weighing around 70 pounds to 80 pounds (including the weight of the battery) to your office or home, it can be quite inconvenient.



If you are a racer or seeking additional speed with an electric bicycle, a heavy bike will not provide satisfactory performance. Yes, the motor can certainly provide enough power to reach a certain speed, but the weight of the bike will be the biggest drawback in terms of speed.



If you are a racer or enthusiast looking to enjoy decent speed on an electric bicycle, you can certainly opt for a carbon fiber frame and rims, remove suspension systems, and add tubeless tires to shed a few pounds. However, in doing so, you may have to compromise on comfort.



Does the weight of the electric bicycle battery affect speed?


The weight of the electric bicycle battery certainly affects speed.



Let's consider a real scenario where you participate in a race, and you've done everything to make your bike lighter—using tubeless tires, carbon fiber rims and frame, and even removing suspension systems; you are satisfied with the weight of the bike.



But when you add a 20-pound battery to the bicycle, firstly, the weight distribution becomes uneven. The motor can provide enough torque to increase speed, but the weight of the battery makes it challenging to maneuver the electric bicycle.



Despite having a lightweight bike, the weight distribution, maneuverability, and ultimately the speed of your electric bicycle will be affected; all the blame falls on the battery.



How much does a lithium-ion battery weigh?


A decent lithium-ion battery weighs around 17 pounds. You may also find batteries weighing around 8 pounds, but their performance may not meet the standards.



Generally, lithium-ion batteries containing lithium, graphite, nickel, and metal oxides may have relatively higher weights compared to regular batteries. However, efforts are constantly being made to make them lighter while maintaining the standards of electric bicycles.



Why are electric bicycle batteries so heavy?


Electric bicycle batteries are heavy due to their construction materials and configuration. If you want the battery to have a larger capacity and voltage, you need to incorporate a sufficient number of individual batteries inside the battery pack.



These batteries have anode and cathode structures made of metals, along with copper, graphite, metal oxides, and other essential components. The weight of the plastic casing around the battery is negligible; it is primarily the inherent weight of these materials that adds to the overall weight of the battery.



It's a simple trade-off: if you want higher capacity in your electric bicycle battery, you will have to accept the burden of its weight.



Conclusion


For riders who value speed, having a lightweight electric bicycle is essential. The best way to reduce the overall weight of an electric bicycle is by using lightweight batteries.



The weight of the bicycle frame and motor is fixed and cannot be changed, but using a carbon fiber frame can help. Tubeless tires and carbon fiber rims can also significantly reduce weight.



Lead-acid batteries may be cheaper, but they are heavy to carry. For leisure use, an 8-pound lithium-ion battery would be the best choice.

All electric bicycles are powered by batteries, allowing riders to easily commute. Some electric bicycles have batteries that can be easily removed with a simple key. However, there are electric bicycles with non-removable batteries, which means that if the battery fails, you won't be able to ride in electric-assist mode. I will show you some tips and tools to make it easier for you to remove the battery.

Furthermore, by taking out the battery and keeping it indoors at home or in your workplace, it reduces the risk of theft.



Does using an electric bicycle without a battery affect its functionality?


Whether by choice or due to a depleted battery, an electric bicycle functions the same as a regular bicycle when the motor is not in use.



Regardless of the reason for riding without a battery, you can rest assured that it will not damage the motor or the bicycle. The only difference is that your muscles will bear the sole burden of propulsion.



The weight of an electric bicycle depends on the pedal-assist components and the inherent resistance of all the power system components. These factors will affect your riding experience without the battery.





Why are Rad Power Bike batteries challenging to remove?


Rad Power Bike batteries are difficult to remove because the battery terminals take up some space at the bottom, making it challenging to slide or pull the battery out by the terminals.



Therefore, you have to be careful to only push or pull the battery itself, not the terminals. Otherwise, your efforts will be in vain. Due to the battery and terminals being made of the same material and almost seamless, it's easy to forget this distinction.



Instead, look for any fractures. You must regularly lubricate the battery attachments to prevent them from becoming nearly hard to remove. You should lubricate the bike’s battery as well as the area where it attaches to the bike



Should I keep the battery on or off when it's on the bike?


When not using the bike, it is always advisable to remove the battery from the electric bicycle. There are a couple of reasons for this. Firstly, it is for safety considerations.

The cost of the battery is approximately one-third of the bike's cost, and electric bikes are more likely to be targeted by thieves. If an expensive bike is stolen, separating the expensive battery can mitigate the loss.



Is removing the battery enough for theft prevention?


It is not foolproof since people can still ride the bike without the battery, so it doesn't completely deter theft. Most bike thefts are crimes of opportunity. If someone with questionable morals sees an unlocked bike while out and about, they might think it's easier to ride away with it. So they hop on the bike, ride to their destination, and ultimately, it disappears.



Why is my e-bike battery not working as it used to?


For instance, your e-bike now only charges up to 48V when it used to reach 54V. Additionally, it has become weak and sluggish, with a sharp drop in battery level when accelerating.



1. End of battery life:

Your battery may have reached the end of its life. However, it could also have internal damage due to various factors such as age, number of charge/discharge cycles, and more.
