A Thorough Guide to Electric Bicycle Battery Systems

DEC 29, 2023


Batteries are an important part of electric vehicles, including electric cars, bikes, and electric bicycles. Having a healthy and good battery for these types of vehicles is important as it's the only source of power for them.

Understanding the electric bicycle battery systems will help the user in having a smooth ride over a long span. When it comes to the convenience of an electric bicycle it is much easier than riding a traditional bicycle. However, you can't go too far without a good working electric bike. For this, you need a healthy battery system.

Electric bicycles equipped with high-quality batteries not only make pedaling easier but also enable riders to cover longer distances without the fear of running out of power. These bikes equipped with efficient batteries excel in muddy areas, uphill climbs, and challenging areas. Where a normal bicycle rider would face a problem, electric bicycles come into play and have a significant advantage.

The battery's role in ensuring uninterrupted power is important for riders relying on electric bicycles for their daily transportation needs. We need to discuss the batteries to understand the system.

Knowing the Type of Batteries: 

But batteries for electric bicycles aren't all the same.

1.Lithium-ion (Li-ion)

This is the most typical style of battery for electric cycles. The main reason is that it's a primary choice battery for an electric bicycle. Also, it is the lightest type of battery used in such devices. This weight factor counts above all else for you, right?

In addition, it is said to last longer than other sorts of electric bicycle batteries. It can last from 50 to 100 times, say some. It also comes in various shapes and sizes, which will be very helpful as this can help produce more leisure-oriented e-bicycles.

NAKTO bikes, for instance, are electric bicycles that use lithium-ion batteries and have a reliable battery.

Although lithium-ion batteries are more expensive than ordinary ones with similar capacities, they generally have good capacity and therefore it is best to keep one. For trips away from home you should have a good source of power.

      2. Nickel-Metal Hydride (NiMH)

In older electric bicycles, Nickel Metal Hydride is used, but in modern electric bicycles, it's not that common. This is mainly because of Lithium-ion taking over. 


Lead-acid batteries are not that often found in electric bicycles due to them being heavy as compared to Lithium-ion.

Other emerging batteries might be a better version of lithium, which might take over, but currently, companies like NAKTO Ebike use the latest battery technologies.

Batteries Details: 

It can’t be the right guide for electric bicycle batteries without its details. Every moving car and bike uses batteries, so there are details for them as well. The most important details are voltage and the capacity.


Voltage calculates the electric difference between two points in a loop. For e-bicycle batteries, it shows how strong the electrical power is for the bike's motor. Electric bicycle batteries most often come in voltages from 24 to 72 volts.

Batteries with big voltage usually make the motor more powerful, giving better performance and speed. However, it's important to match the battery voltage with the electric bicycle’s motor and controller to ensure they work together correctly.

This means that if an e-bike battery has more voltage, it can give more power to the motor, letting the bicycle go faster.


With voltage, there is capacity as well. Battery capacity means how much energy a battery can hold and give to the electric motor. It is usually measured in ampere-hours (Ah) or watt-hours (Wh). The capacity of an electric bicycle battery directly acts on how far it can go on a single charge. A higher-capacity battery can hold more energy, allowing your electric bicycle to travel cover distances.

This is mainly important for people who use their electric bicycles for long or comfortable rides. The tie between capacity and range is guided by details like the motor's well, and the land.

When picking an electric bike battery, think about voltage and capacity. Your choice hangs on how fast you want to go, how far you want to ride, and if it works well with your electric bicycle’s motor and controller.


The weight of electric bicycle batteries is an important reason to think about. It works on the overall weight and balance of the electric bicycle, which in turn changes how the bike handles and the riding feels.

Different types of batteries have different weights. Because they are light and high-energy, lithium-ion batteries have gained a reputation. Since lead-acid batteries are rather large, they have been largely replaced by modern e-bikes.

After all, the weight of batteries affects an electric bike's whole balance. This, in turn, changes the feel of riding a bike. Different batteries have different weights.

Here is a link to a YouTube video for a better understanding of how this all works

Mounting and the Integrated Batteries:

Modern electric bicycles all come with built-in batteries. The batteries are mounted in the frame of the bike, which not only looks good but is stylish like regular bicycles. This not only adds to the traditional appearance of the bike but also makes for a smooth face overall.

This also helps protect from the weather and increases the life of the battery. Because it is inside the body of the electric bicycles, this helps the battery be intact in the body of electric bicycles and has less chance of being damaged.

Some electric bikes have batteries outside, sometimes on the downtube or rear rack. This is done for comfort, making switching or upgrading the battery easy. Some e-bikes, especially those made for flexibility and easy care, might put the battery on the outside.

It's suitable for those batteries that are large and have a larger capacity—making it easy to remove the battery.

Charging Time:

Different types of bikes require different lengths of time to charge. The time required to recharge batteries is vital and helps determine just how convenient an electric bicycle can be. That is, it refers to the time required for a fully discharged battery to be completely reloaded. Charging time varies according to the battery's capacity and the power output of the charger.

Many factors determine how long lithium-ion batteries for e-bikes take to charge. The reasons are varied--from the battery's energy capacity (expressed in watt-hours) to its state of charge, from the charger's power output and condition, and so on.

However, the higher-capacity battery requires more time to charge because it has more energy to replace. Smaller capacity batteries can be recharged more rapidly. In addition, being partly used up means that it is often quicker to recharge.

Maintaining a Battery: 

It all depends on how you maintain your battery. No matter how expensive your battery is. A lot of things determine the maintenance of electric bicycle batteries. From how a person charges and for how long. Every reason changes electric bicycle batteries' overall performance.

This also refers to the condition and damages of your electric bicycle. Or because maybe the tires of electric bikes are low or without air. In other words, the power needed to propel one's bicycle forward would fall on this weight. But this not only uses energy, it shortens the battery life.

The other reason is overcharging. Any overcharged battery poses dangerous situations for the motor, the individual, and others in its vicinity. But overcharging is also dangerous because batteries contain chemicals that are harmful to our bodies.

But overcharging accelerates this damage by generating more heat while charging. Charging faster this way, however, is damaging to the battery's long-term health. In addition, overcharging the battery can shorten its life and eventually change performance.

Tip: Taking Care Of Your Bicycle Batteries: 

Fortunately, there are methods you can take to keep your battery servant so that it will accompany you on the long road of joy-riding electric bicycles. Here are the steps.

Always respond to a hot battery in the same way as you do it to food: allow it to cool down before using or charging it again. Avoid charging or using the electric bicycle's battery when it is hot. Batteries can become hot due to various factors. High outside temperatures can lead to battery overheating. Additionally, climbing steep slopes can cause the motor and battery to heat up.

Always store a battery in a cool place—at room temperature. A very high or low temperature can damage a battery's life. Make sure to keep it away from the sun's light or near where there is sun heats. This also includes when parking your electric bicycles. Don't park it where there is sun's rays.

Even in cars, people park their vehicles where there is a shade or a shadow—the same with electric bicycles. Due to its detachability, the battery can accompany the rider home so it doesn't get exposed to the sun and explodet. Furthermore, as long as there is an average temperature inside and normal air circulation slowing down will do nothing at all.

Due to its detachability, the battery can accompany the rider home so it doesn't get exposed or ruined. Furthermore, as long as there is an average temperature inside and normal air circulation slowing down will do nothing at all.

In other words, BMS has four starring roles for batteries.

1.The lithium-ion batteries used in electric bicycles are formed of a combination of series and parallel circuits. However, some variation in the cells 'voltage may occur due to manufacturing or usage factors. The BMS continually monitors the voltage of each cell and transfers energy between them to balance things out. This allows none of the cells to become overcharged or under-discharged, keeping all in good working order.

2.Defects caused by overcharging include such things as heating, slow performance, and safe applications. However continual discharge can damage the integrity of a cell and shorten battery life. The BMS acts to counter these situations by closely monitoring the system's voltage levels. But if it comes near dangerous levels, BMS intervenes to prevent overcharging or discharging, maintaining the well-being of its cells.

3.The BMS monitors the battery's temperature and takes appropriate action, such as waiting for it to cool or halting power delivery until temperatures normalize. Can temperature changes act on the performance and safety of lithium-ion batteries? This temperature control is one of the things that makes the battery safer and more trustworthy.

4.The State of Charge determines how much energy is currently in the battery, and is determined by the BMS. A correct SOC also allows riders to accurately determine the distance their bicycles can travel. The BMS tests the battery's voltage, current, and temperature to obtain accurate data on residual capacity.
