[Guide] Ebike Battery Types – UPDATED 2022


If you’re shopping for an electric bike, one of the most critical components to check for is the battery. The battery controls how far an electric bike can travel, how long it can be used before it needs to be recharged, and how heavy the bike is overall.

Because the battery is one of the most expensive components, it is an important consideration to consider when purchasing an e-bike.

An electric bicycle that does not have a battery is simply a conventional bike with no special features. The answers to all of your queries will be provided in this essay. There is also a lot of information regarding electric bike batteries.

Continue reading to find out how to choose the greatest e-bike battery for your needs.

What Is an ebike?

E-bikes are bikes that have an electric engine incorporated into the frame of the bicycle. This motor, in some way, assists the rider in moving ahead. This assistance is often defined as the provision of pedal-assist or throttle assist.

PEDELECS (pedal-assist electric bicycles) are a popular alternative because they give power assistance through calibrated acceleration as the user pedals. In contrast to the throttle-assist e-bike, which looks more like a motorcycle than an e-bike, you get the option of either pedaling or utilizing the engine to go around.

Ebike Battery Types

What Is the Power Source for an ebike?

Power for the electric drive motor comes from the battery system, which also serves to determine how far the automobile can travel.

Lithium-ion battery packs are used in the majority of electric bikes. The size of the battery pack is determined by the kind of bicycle and the price of the bicycle. It is possible to use up to three battery packs on some ebikes for touring and commuting.

Recharging rechargeable batteries by plugging them into a conventional electrical socket is the quickest and most convenient approach to restoring their full power. System performance and quality affect the length of time it takes to recharge.

How to Choose an ebike Battery?

When it came to building electric bicycles in the beginning, the batteries were the most difficult to work with since they were so large and heavy in comparison to modern batteries. Lithium-ion polymer batteries are frequently seen in e-bikes that are brand new or recently purchased. Multiple methods can be used to make older e-bikes function properly.

Batteries made of nickel-cadmium and nickel-metal hydride were used in the early days of e-bikes to replace lead-acid batteries. They were small and light, and they were capable of sustaining a significant amount of power over short trips.

It is necessary to first comprehend the language that is used to explain e-bike batteries before you could even make an informed purchase. These can help you gain a better knowledge of your battery’s performance.

Voltage (V)

Amperes (Amps)

Watts (W)

Watt-hours (Wh)

Amp-hour (Ah)

Capacity

Voltage (V)

Volts is a name that is commonly used to refer to this system of measurement. An electric bike battery voltage of 400 volts or more is recommended for an electric bike.

The Amperes (Amp)

This is a way to measure the flow of electricity. It is a universally accepted unit of measurement. Amperes may be connected to the size or diameter of a conduit in the same manner that water flows through a pipe or conduit. According to this hypothesis, greater amperes would imply a larger pipe with a higher water flow rate per second than a smaller pipe.

Amp Hours (Ah)

When the batteries in a battery pack begin to degrade as a product of use, the voltage of the rechargeable battery will gradually decline until it reaches zero. The capacity in amp-hours of a battery is approximately equal to the battery’s durability (Ah).

Battery packs with a capacity of one Ampere hour can produce one amp for an hour of continuous use. In most cases, the battery capacity of an ebike is less than ten amp-hours. In the case of a bike that draws 15 amps on average and has a ten Ampere hour battery, a simple mental calculation indicates that the bike’s battery life is forty minutes.

As the amp-hour capacity of a cell increases, so does its size and price.

Capacity (C)

Generally, the cost and complexity of a battery cell are proportional to the number of amp-hours it can store in its capacity.

A battery’s ability to maintain a fixed amount of amps for one hour is measured by this figure out the capacity rate. For a half-hour, use two times the amps. Or, for two hours, reduce the amps by half, etc.

The energy of a battery decreases in direct correlation with the number of discharge-charge cycles it experiences. Recharging and discharging a battery to 10% of its capacity is called one cycle.

The number of cycles and the battery’s operational parameters influences the actual battery life. The battery’s cycle life decreases when it is depleted over an extended period.

Watt-Hours (Wh)

When determining how far a battery pack can go, the watt-hour capacity of the battery pack is more important than the amp-hour capacity.

Those unfamiliar with the kilowatt-hour unit of measurement should know that one watt-hour is one-hundredth of that.

The watt-hour capacity of a battery pack may be estimated by multiplying the pack’s actual amp-hour capacity by the voltage of the battery pack in question.

Watts (W)

Once it comes to energy production, the device is standard fare for its class. If you boost the wattage of your electric bike, you may be able to create more power. Similarly, watts are likewise similar to one voltage doubled by one ampere, which is equivalent to one volt doubled by one ampere and so on.

What Are the Types of Batteries?

Electric bicycle battery packs typically use one of four types of e bike batteries.

Lead Acid batteries.

Nickel-metal Hydride.

Lithium-ion.

Nickel-cadmium.

The Lithium-ion batteries are now standard equipment on all new and newly announced electric motorcycles, as well as on older models. It is possible to find older second hand e-bikes with a variety of chemistries, such as those with huge lead-acid batteries.

Back then, nickel-cadmium and nickel-metal hydride batteries were introduced, both of which were lighter and could still be purchased with a respectable amount of energy for shorter trips, making them perfect for anybody looking to save money on an e-bike by “hacking” it together from parts.

Even though nickel and lithium batteries are more expensive and difficult to use, many people prefer them because they are more reliable, robust, and powerful than other battery kinds.

Battery types using lithium-ion technology have been hailed for their benefits in terms of cobalt, manganese, and other materials.

Types of Batteries Explained

Lead Acid Batteries

The Lead-acid batteries are both affordable and easy to dispose of, giving them a suitable option for rechargeable batteries. It is the first time in human history that recycling generates more amounts of lead than mining.

They do, however, require frequent maintenance and have a limited lifespan. Avoid using this route if you wish to ride your bicycle to work. It is not safe. Several reasons contribute to the cheap cost of lead-acid batteries, including:

  • Basic, affordable materials.
  • In comparison to Nickel Metal hybrid batteries, they are twice as hefty and 3 times as weighty as lithium-ion batteries.
  • They have significantly less useful power as compared to Nickel-metal hybrid and lithium batteries. Batteries composed of nickel or lithium last approximately half as long.

However, lithium iron phosphate batteries are gradually replacing lead-acid batteries as the preferred battery technology. In tandem with the decline in battery prices, the average cost of lithium iron phosphate batteries as well as the battery’s average life has both decreased.

Nickel Metal Hydride Batteries

The ebike’s Nickel Metal Hybrid batteries are more costly as compared to Nickel Cadmium batteries, although they are more energy-efficient.  According to the vast majority of individuals, the advantage of the Nickel Metal Hybrid over Nickel Cadmium in terms of range is negligible.

They both are more durable and easier to dispose of than other options.

Despite this, nickel-metal-hydride batteries are not known for their long-term reliability. It may be difficult to keep them operating and charge them consistently.

The heat generated by nickel-metal hydride batteries is significant even when the batteries are not in operation.

Self-discharge occurs in a short period. Even though this battery drains at a slower pace than nickel-cadmium batteries, it is not deemed to be safe for use in electric bicycle applications.

Lithium-Ion Batteries

The most prevalent battery for e bikes in the market is Lithium-ion batteries, and as a result, they will be found in all new electric bicycles.

When it comes to distance and living standards, lithium-ion batteries are the most efficient when it comes to weight and energy consumption.

Lithium-ion batteries may also be formed into various shapes or areas, making them ideal for programs that demand both a large quantity of power and a minuscule portion of power at the same time.

Considering the chemistry of lithium-ion batteries, there is no consensus among experts about whether lithium cobalt batteries or lithium manganese batteries are preferred to one in comparison to each other.

Purchase a bicycle with a reliable electric motor system and well-constructed components to prevent the battery from overheating and extending its life.

Nickel Cadmium Batteries

You may be able to get a very long life out of these batteries if you treat them with care. In comparison to lithium batteries, they have less energy per unit volume, but they have more energy in the form of lead-acid batteries.

Furthermore, nickel-cadmium batteries are more capable of withstanding heavy volumes than other types of batteries. They are capable of withstanding significant pressure.

Unfortunately, they have several significant drawbacks. There is an extremely high percentage of self-discharge in them. A full charge that is left inactive for 24hrs could mean a loss of capacity of up to 70 percent. They have poor electrical conductivity compared to other materials.

For starters, the principal component of nickel-cadmium batteries, cadmium, is a very dangerous contaminant that should be avoided. Nickel-cadmium batteries have become outdated as a result of environmental worries and regeneration initiatives.

These cells are not the best option for your electric bike’s battery pack because they have a low capacity.

Does My Car's Battery Have Enough Energy to Power an Electric Bike?

Does My Car’s Battery Have Enough Energy to Power an Electric Bike?

To complete your e-bike project, you should not utilize a vehicle battery. A vehicle battery might technically be used on an e-bike, however, lithium batteries offer a greater range and more power than lead-acid car batteries while being significantly lighter.

Furthermore, because automobile batteries are large and cumbersome, they will not fit comfortably in the body of your bicycle.

Do Electric Bicycles Have the Capacity for a Huge Battery?

You can usually convert a standard bike into an e-bike or upgrade your e-battery bike’s capacity by purchasing a larger battery.

When it comes to replacing an e-bike battery, there are several variables involved. Which includes the additional cost and complexity, which may make it very difficult to ride the bike and reduce its e-mobility, among other things. 

For those who normally keep their electric bikes indoors or have to move them up and down many flights of stairs, this final advice is critical.

The general guideline is to size your battery according to the predicted average distance traveled, rather than overpaying on a larger battery that you will not utilize to its maximum capacity.

In the situation that your old battery is nearing the end of its functional life, you may indeed be able to earn costs on the newly bought one.

Think about the fact that your commute route is thirty kilometers round-trip. You can continue if the battery has a little more energy left in it. Recharging at work, on the other hand, can extend the range even farther.

How to Charge E Bike Batteries for the Very First Time?

When you are using your e-bike for the first time, it may take twelve hours for the battery to power up. Recharge the batteries till the charge light on the battery no longer blinks.  A prolonged initial voltage ensures that every one of the cells in the battery functions properly by allowing the battery usage to become used to being recharged.

How Can You Save Battery From Destroying?

First and foremost, consider the battery’s on/off switch. The term “sleep mode” is frequently used by well-known battery manufacturers. To activate the e-battery on the bike, either press a button on the handlebars or use the controlled display.

So when the electric bicycle is switched off or the battery is allowed to “sleep” for some time, the Battery Management System begins to lose power and malfunctions.

While you’re riding, press the button one more to switch the battery back on.

What Are the Benefits of Using Lead-Acid Batteries?

Lead-acid batteries are the least costly type of battery available. Lead-acid batteries are available from a plethora of local and online merchants. The cost of Sealed Lead Acid batteries can be decreased by purchasing them in person rather than online, which reduces delivery fees. They will very certainly be accessible at hardware and electrical stores.

In addition, lead-acid batteries can generate a significant amount of power. Lithium batteries, in general, do not enjoy being subjected to high currents. Sealed Lead Acid batteries, on the other hand, have the capability of delivering extremely huge currents. A Sealed Lead Acid battery may be used in the construction of a strong electric bike.

How to Maintain My E Bike Batteries?

It’s important to take a few basic steps to ensure that your battery’s health is maintained:

Choose Right Charger

The first thing you need to make sure of is that you are using the right charger for your battery.

Do Not Over Charge

It makes no difference whether you use the batteries or not; it will ultimately run out of power. If you intend to keep a lithium battery for longer than a few months, please follow the company’s guidelines for battery issues.

Companies may specify that their products need to have between thirty and sixty percent of their battery recharged when they are taken out of storage, for example. This indicates that they are quite likely to be put into effect in the future.

Avoid Mishandling

You need to avoid providing battery shocks and jerks by treating it harshly or without being careful, as this might shorten the battery’s life span.

Don’t Leave It Plugged After Charged

When charging a lithium battery, do not keep it plugged in after it has reached full capacity.

Parting Shot

Choose a Lithium-ion battery for your electric bicycle from among a large number of possibilities, and you may find yourself bewildered by the choices. When compared to other products, lithium cobalt distinguishes out since it has a higher energy density per unit weight than the other elements. However, this does not rule out the possibility of using multiple kinds of Li-ion batteries in an electric bicycle.

It is better for the environment and safer to use lithium manganese batteries. A greater cell voltage can be seen in lithium manganese batteries compared to lithium cobalt batteries. Lithium manganese batteries, on the other hand, have a 20 percent lower energy density than lithium cobalt batteries.

The lithium-ion chemical of lithium manganese provides even additional advantages, such as rendering the metal more resistant to high temperatures and more affordable. Furthermore, the type of Li-ion battery you select will be heavily influenced by the number of funds you have to invest.

You must purchase the proper battery for your motorcycle. In the absence of this, you will not be able to maneuver your bike without taking any breaks.
