Weight vs Performance: How Much Does an Ebike Battery Weigh?

The battery is the most crucial and expensive component on your ebike. Did you know that next to the motor, it is among the heaviest too?

The thought has crossed your mind often. “How much does an ebike battery weigh?” “Does that weight affect how fast I go?”

These are good questions, the right ones. 

Sit back as we unravel ebike batteries, their weight, cost, composition, and how they all fit into the grand scheme of your ebike.

Here is all you need to know about your ebike battery summed up into a read-only Ted Talk.

Let’s dive in.

Electric Bikes Batteries: Weight vs. Performance

Many ebike enthusiasts wonder, “How much does an ebike battery weigh?” The other thought includes if the weight indicates its authenticity and whether it’s connected to performance.

In the real sense, quality, size, performance, and price go hand in hand for top brands such as Samsung and Panasonic.

Ebike batteries for ebikes and mobility scooters weigh between five to ten pounds ( 2-4 kg). A standard 48 V, 15 A battery (most common among ebikes) weighs around 10 pounds.

Your Electric bike battery capacity is directly proportional to the weight, meaning the higher the power production capacity, the more the battery weighs.

That’s a plus.

The downside to this relation is that the weight of a battery doesn’t qualify it as the best. 

Some smaller batteries outlive or outperform larger batteries because of other factors like their chemical composition.

Before we get into the juice, here are some of the best battery selections on the shelf to examine the average ebike battery cost.

The prices of quality ebike batteries are slightly high but justified. Now let’s get to the fun part - why are ebike batteries so expensive?

History of Electric Bike Batteries 

Electric batteries date as far back as 1800 AD, consisting of a copper wire, zinc wire, and electrolyte separated by a cloth.

The early models provided less power and got depleted fast. Thankfully, early innovators like Alessandro Volta kept trying until we made breakthroughs in the 20th century.

With time, technological advancements produce effective batteries because the top brands try to outdo each other by making smaller and more powerful batteries. 

This is so the battery occupies less space on ebikes with removable and hidden batteries and produces power for hours.

Below are the main types of electric bike batteries that you’ll find on the most common electric bikes.

Types of Electric Bike Batteries

Thanks to the diversification of technology, different electric bike battery manufacturers make more convenient batteries than their ancestors.

The types of ebike batteries are determined and named by their chemical composition. This, in turn, determines the weight, performance, and cost of the ebike battery.

The most common types of electric batteries are:

  1. Lithium-ion battery
  2. Lead acid battery
  3. Nickel-cadmium battery
  4. Nickel metal hydride battery

Let's dig deeper to understand how they work and which type fits into your ebike motor like a glove.

Lithium-ion (Li-ion)

Lithium-ion batteries are the most common electric bike batteries. This type of ebike battery uses lithium ions as the major chemical component/electrolyte to produce charges.

Li-ion batteries weigh less compared to the other types of ebike batteries (around 2kg/5 lbs). They also take a shorter time to charge and can cover up to 100 miles(160km) on a full charge.

Lithium-ion batteries also have a low discharge rate, retaining power even in standby mode. They are mainly used for removable ebike batteries.

Lead Acid Battery (SLA)

Lead acid batteries are the safer ebike batteries since they are pre-sealed on purchase, aka Sealed Lead Acid batteries (SLA).

SLAs have a relatively higher power output than Lithium-ion batteries because Lead acid batteries are heavier than Li-ion.

The only downside is that lead acid batteries leak toxic chemicals when exposed to wet conditions and then left lying on the side.

On the bright side, SLAs are also the cheapest ebike batteries.


Nickel-Cadmium batteries are pricey compared to their competitors but for a good reason. This type of ebike battery is effective in the long run, as they are the most potent type of ebike battery.

These batteries give you longer running times, but they are getting wiped out from the market because of their toxicity and difficulty in recycling.

Nickel Metal Hydride

A nickel metal hydride battery is a rechargeable battery that balances a Li-ion battery’s long life span and SLA’s short one.

This type of battery has a very high density necessary for long trips but gets depleted quickly.

Key Features of Electric Bike Batteries

The standard features of electric bike batteries are the main checklists for buying a new battery or replacing your old one.

These basics help you know which battery is compatible with your ebike so you always get the right one. 

Here is what to look for as you shop for your ebike battery.

  1. Capacity
  2. Voltage 
  3. Watts

Let's check them out in detail.

  • Capacity 

Battery capacity is the total amount of power generated by a battery as a result of the chemical reaction in the battery. It is usually expressed in ampere per hour (ah).

The most useful electric bike batteries have a capacity of around 10 ah.

  • Voltage

Voltage is the pressure your electric battery produces to push the electric current. An ebike battery with a high voltage produces more power on the road.

An ideal ebike battery voltage ranges between 36V-48V.

  • Watts 

Battery watt is the combined unit of power when the voltage of a battery acts on its capacity. This is the amount of power your battery produces regularly.

Most ebikes have batteries ranging between 300 to 500 watts, but 700W ebike batteries are becoming more common to provide more power on your rides.

Factors to Consider Before Purchasing Electric Bike Battery 

Before spending money to buy any electric bike battery, always consider the following factors:

Cost of the Battery vs. Performance.

The price of the ebike battery matches the battery’s chemical ability. Lead acid batteries are cheaper than Li-ion batteries and produce more power, but the Li-ion battery lasts longer.

In relation, the cost of your battery is repaid with a long-lasting quality performance.

The Ebike Battery Brand.

Electric bike batteries from reputable brands render the best service. The best battery cells from reputable manufacturers will serve you for over three years.

They also have effective features like low discharge rates and monitoring systems. The major brands of ebike battery brands to look out for are: 

  1. Samsung 
  2. Yamaha 
  3. LG
  4. Bosch 
  5. Panasonic 

Final Thoughts

Your ebike battery weight determines its power, so a heavy battery isn’t necessarily bad.

After going through this detailed guide on ebike batteries, you can comfortably say that you understand your ebike and its functionality a little more.
