Is It Better To Have a Removable Battery On an eBike?

E-bikes come with the possibility of having a removable or integrated battery. However, I’ve found that many need clarification about which is better. Both batteries have pros and cons to consider before making your decision. 

A removable battery on an eBike is safer, more portability, convenience for carrying and charging, security, and hassle-free replacement when a new battery is needed. It’s much easier to store a battery indoors as compared to a entire bike. 

This article covers all you need to know about eBike removable batteries.

What is meant by a removable eBike battery?

A removable e-bike battery is a type of battery that you can detach from the e-bike for charging or replacement purposes. Removable batteries are typically housed in a compartment or holder on the bike frame and secured with a lock or a latch. 

Some e-bikes have a battery that can be easily removed and inserted into a charging port. In contrast, others require a more involved process to remove the battery.

The design of a removable e-bike battery can vary depending on the manufacturer. Still, generally, they are designed to be compact, lightweight, and durable. They are also designed to meet the electrical requirements of the e-bike, such as voltage and current, and to be compatible with the e-bike’s control system.

The size, weight, and capacity of removable e-bike batteries can vary, depending on the make and model of the bike and the intended use. For example, some e-bikes have relatively small batteries that provide a limited range. In contrast, others have larger batteries that offer an extended range.

What are the advantages of a removable eBike Battery?

The benefits and drawbacks of having a removable battery on an eBike depend on several factors, including the type of eBike, the bike’s intended use, and the rider’s personal preferences. 

But in general, here are some of the main advantages of removable batteries:

1. Convenience

A removable battery can easily be removed and brought inside to charge or replaced with a fully charged battery if needed. You can charge removable batteries at a convenient location, such as your home or office, instead of bringing the entire bike inside for charging.

Charging the removable battery inside with a steady ambient temperature is generally better. In addition, charging a battery in a controlled environment can extend its lifespan and ensure optimal performance.

Extreme temperatures, whether hot or cold, can negatively impact a battery’s performance and lifespan. In addition, high temperatures can cause the battery to degrade faster and be a safety hazard. 

Low temperatures can reduce the charging efficiency and increase the charging time.

By charging the battery inside with a steady ambient temperature, you can avoid these issues and ensure that the battery charges safely and efficiently. A controlled environment can also help protect the battery from physical damage and reduce the theft risk.

2. Easy maintenance

Removable batteries are easier to replace or repair if they stop working without needing a professional (thus cheaper). You can do it by yourself. When you want to clean them, you can do it in a few minutes, which can help to extend their lifespan.

3. Easy to store inside

You can store removable batteries in a safe and secure location, which reduces the risk of theft or damage. In addition, if you store the battery inside, out of the cold, you can extend its lifespan. 

Cold temperatures can harm the performance and lifespan of a battery, and storing the battery in a cold environment can make it difficult to charge and use.

A cold environment can cause the battery to degrade faster, reduce its charging efficiency, and increase the charging time.

4. Possibility to reduce weight and bike normally

You could remove the battery to reduce weight and bike normally—some riders like the idea of using the eBike as a typical bicycle once in a while. 

It is possible with eBike models with a removable battery. Removing the battery can reduce the bike’s weight, improving handling and making it easier to maneuver, especially on challenging terrain.

Removing the battery can make it easier to transport the bike, as it can be more compact and lighter without the battery.

5. Easy to transport

Weight transporting can become vital if you have to move by plane. If you need to transport your ebike, a removable battery makes it easier to disassemble and fit it into a car trunk or other transportation mode.

It can be beneficial for people who need to transport their e-bike by car, train, or plane, as it reduces the overall size and weight of the bike.

6. Security 

Suppose you need to park your eBike outside for extended periods. In that case, you can remove the battery and bring it with you for added security. Removable batteries in e-bikes can be vulnerable to theft, as thieves can easily remove and take them away. 

Although you could use a lock or keep the battery hidden, it is way better to bring it indoors. Storing the battery indoors, such as in a garage, basement, or closet, can reduce the risk of theft and keep the battery safe and secure.

7. Flexibility

Using an eBike model with a removable battery allows you to bring a spare battery on longer rides and extend your range without stopping for recharging. 

Are there some disadvantages to using removable eBike batteries?

Removable batteries are typically more expensive than integrated batteries; they require additional components, such as a locking mechanism or a charging port, to function correctly.

In addition, they are often heavier than integrated batteries, which can affect the handling and balance of the bike.

They have a lower capacity or range than integrated batteries, especially if they are removed and reinserted multiple times.

E-Bike’s removable batteries can be more vulnerable to damage, as they are exposed and are more easily bumped or knocked around. In addition, protecting the battery from elements like rain, snow, and dust is more complicated.

A removable battery might be the right choice if you value convenience and portability. However, an integrated battery might be better if you prioritize range and simplicity.

Tips for keeping your battery healthy

It’s generally a good idea to keep your e-bike battery healthy. By taking care of the battery and following best practices, you can prolong its lifespan and maintain its performance, which can help to ensure that you get the most value from your e-bike.

A healthy battery is essential for a smooth and reliable e-bike experience. It provides the power needed to assist the rider and can make a big difference in range and performance. 

RIDE eMTB Tip: I learned this the hard way. Buy a good battery with branded cells like LG or Panasonic. Then take care of it, no extreme temperatures and never discharge until it dies. Try not to charge it if it’s hot and use the charger that came with the battery. The battery is one of the most expensive parts of an eBike. It has something called a BMS which controls the battery (it can shut the battery down)

Taking care of the battery can reduce the risk of unexpected failures, prevent the need for costly repairs, and extend the overall lifespan of the bike.

1. Store the battery in a proper environment

Extreme heat or cold can affect the battery’s performance and lifespan, so it’s best to store it in a place with a steady ambient temperature.

Regularly charging the battery helps keep it healthy and maintain its performance. However, avoid letting the battery completely discharge, as this can reduce its lifespan.

3. Avoid overcharging

Overcharging the battery can reduce its lifespan, so it’s important to avoid charging it for too long or to a higher voltage than recommended by the manufacturer. Typically, it is challenging to overcharge an eBike battery by letting it on the charger for too long. Still, with damaged equipment or charger, accidents can happen. 

4. Avoid exposing the battery to moisture

Moisture can damage the battery and reduce its performance, so it’s essential to avoid exposing it to rain or other sources of moisture.

5. Keep the battery clean

Regularly cleaning the battery and the charging port can help to prevent damage and reduce the risk of corrosion.

6. Use the correct charging equipment

Using the correct charging equipment can help prevent battery damage and prolong lifespan. Use only the charger provided by the manufacturer or a compatible replacement.

7. Avoid extreme temperatures

Avoid exposing the battery to extreme temperatures, such as leaving it in a hot car or exposed to direct sunlight, as this can affect its performance and reduce its lifespan.

8. Check for signs of damages

In addition to the tips I mentioned earlier, it’s also essential to regularly inspect the battery for signs of damage or wear, such as cracks, corrosion, or loose connections, and to address any issues promptly. 

Internal battery vs. external: Which one should I choose?

Now that the benefits of removable batteries are clear, how do they compare with internal or integrated batteries?

Integrated batteries have different benefits to take into account. For example:

1. Aesthetics: Internal batteries are often integrated into the frame of the e-bike, giving the bike a streamlined look. It can be vital for those who value the appearance of their bike and want to maintain a minimalist look.
2. Protection: Because internal batteries reside inside the bike’s frame, they are, by design, protected from theft and the elements. It can provide peace of mind and help to ensure that your battery lasts longer and performs better. They are protected from the elements and do not need removal for charging or storage. 
3. Better handling: By integrating the battery into the frame, the overall weight distribution of the bike can be improved, resulting in better handling and a more stable ride.
4. Simplified charging: With an internal battery, you don’t have to worry about removing the battery for charging or about finding a place to store the battery when it’s not in use. 

The choice between an internal and an external battery for your e-bike depends on your personal preferences, the riding you plan to do, and the specific requirements of your e-bike.

Internal batteries are built into the frame of the e-bike and are typically more compact and discreet. This type of battery is a good choice for those who prefer a sleek, minimalist look for their e-bike or for those who plan to do shorter rides. 

They are also convenient because they are, by nature, protected from theft and the elements.

External batteries, on the other hand, are often larger and bulkier, but they offer several advantages. 

One advantage is that they can be easily removed and taken with you to charge, making it more convenient for those who plan to do longer rides or want to charge the battery at home or work. 

External batteries can also provide a more extended range. You can swap them for a fresh battery, which is especially useful for those who plan to do extended rides or want a backup battery.
