What to Look For When Choosing a Battery for Your Electric Bike

Are you in the market for a new battery for your electric bike? There are plenty of choices on the market, and knowing what to look for is essential. 


We will give you the necessary information on power, capacity, price, and reliability factors. Our guide will help you choose the perfect battery for all your cycling needs!


What You Need to Know About Electric Bike Batteries


Electric bikes are a great way to get around while reducing your carbon footprint at the same time. Evolving technology has helped spur the growth of the electric bike industry, with an estimated value of $86 billion by 2028.


One of the main reasons for this growth is the evolution of the electric bike battery.


You may be surprised to learn that one of the first electric bikes was patented in 1895 and required a 10-volt battery. Throughout the ensuing years, design changes were made, along with the introduction of newer and better batteries.


The oldest type of rechargeable battery is the lead-acid battery, which was invented in 1859. While it may be inexpensive, it's much heavier than other options and only lasts for a short time. They also aren't environmentally friendly.


Forty years after the introduction of the lead-acid battery, nickel-cadmium batteries came along. They were more expensive than lead-acid batteries but lighter and lasted longer. However, they suffered from memory effects, reducing their capacity over subsequent recharges. 


It would be almost 90 years before the introduction of Nickel-Metal Hydride Batteries (NiMH) in 1986. While they were more energy-dense and environmentally friendlier, they had a shorter lifespan.


Shortly after 1991, the first Lithium-Ion (Li-on) batteries came onto the market. They are light, energy-dense, and compact. Furthermore, they don't suffer from the "memory effect" of their predecessors. 


However, it would take over 15 years before manufacturers used these batteries on an electric bike. But, once that happened, Li-on batteries were the catalyst in the expansive growth of the electric bike market.

Lithium-Ion batteries are still widely used in electric bikes worldwide, but other battery options on the horizon will further revolutionize the electric bike industry, such as:

  • Lithium Iron Phosphate (LiFePo4)
  • Lithium Cobalt
  • Nickel Manganese Cobalt (NMC)

Placement of Electric Bike Batteries

There are three main types of electric bike battery placement:

Integrated

This type places the battery inside the bike frame, usually in the down tube. It provides a more streamlined look and gives the ebike the appearance of being a traditional bicycle.

Seat Tube

This style involves placing the battery on the seat tube of the bike. While the external placement allows for easier access, it doesn't have the same aesthetics as an integrated battery.

Rear Rack

As the name implies, the battery is placed in the rear rack. Even though the battery isn't integrated into the electric bike's design, it can easily be hidden or disguised with a bicycle bag or panniers.


Each style has pros and cons, and the best one largely depends on personal preferences and the type of riding you plan to do. When the battery is located in the bike's center, such as the integrated and seat tube placements, it helps maintain a balanced weight distribution, improving handling and stability. A rear rack placement allows for easier battery removal and larger batteries with more capacity.


What to Consider When Choosing an Electric Bike Battery

Whether you're purchasing a new electric bike or choosing a battery for an electric bike you already own, there are some factors to remember to ensure you get the correct battery for your needs.

Voltage and Capacity

Electric bike batteries with higher voltages and capacity typically mean more power and longer distances. Consider your typical riding patterns to determine if you will need the extra power for steep climbs or if you expect to spend several hours riding a bike.

Compatibility

Check your manufacturer's guidelines to ensure the battery you choose is compatible with your electric bike brand and model. Different bikes may have specific battery shapes, connectors, and mounting designs.

Charging Time

Check to see how long it takes to charge the ebike battery fully. You might want one that charges quickly, especially if you have limited time.

Weight and Size

The battery's weight and size will affect your bike's overall weight and balance. A battery that is too heavy may make your ebike more difficult to handle.

Brand and Quality

Buy a battery that comes from a reputable manufacturer. A cheaper, off-brand battery may be inferior quality and damage your bike.

Warranty

A longer warranty indicates that the company knows it has a quality product and has confidence in the battery's durability and performance.

Safety 

Some ebike batteries have certain safety features, such as overcharge protection, temperature regulation, and short-circuit protection.

Budget

Considering your budget is essential, so comparing prices across different brands is essential. However, don't base your decision solely on a low price. A less expensive ebike battery may not last as long, requiring replacement more often.

Battery Management System (BMS)

A battery management system helps you monitor your battery's health. It helps with the charging and discharging process, prevents overcharging and deep discharging, and ensures balanced cell usage.


Vonax USA Cafe 02 Fat Tire Electric Bike

The Vonax USA Cafe 02 Fat Tire Electric Bike is a statement piece. Its vintage motorcycle design will capture everyone's attention. It has a powerful 750-watt engine and fat tire that transitions easily from city streets to grassy fields. The saddle is large enough for two people to ride comfortably, along with provided footrests for the passenger. 


The external removable 48V/15.6Ah battery is hidden under the seat to blend with the ebike's design and has an impressive 50-mile range with pedal assist. 


The battery placement on the Vonax USA Cafe 02 Fat Tire Electric Bike is challenging to categorize. While the battery is towards the bike's rear, it's not part of the rear rack. And while it is externally mounted, it is done so cleverly that it seems like a part of the saddle.


Micargi Cyclone Chopper Style Fat Tire Cruiser/Deluxe Electric Bike

Here is another electric bike battery placement done well. Micargi's Cyclone Chopper Style Fat Tire Cruiser/Deluxe Electric Bike places its battery next to the chain. The 500 Watt motor is great for commuting or weekend rides. The 4" fat tires roll easily over bumps and potholes in the road. A fully charged 48V/11.6Ah battery can give you a max speed of 28 mph and a range of up to 30 miles.
