As eBikes continue to grow in popularity, the quality and performance of their batteries play a critical role in their overall performance. eBike batteries come in a variety of types, each with its own advantages and disadvantages.
In this article, we’ll explore the primary eBike battery metrics, specifically voltage (V) and ampere-hours (Ah). We also delve into five of the main types of electric bike batteries and the performance that each offers.
First, what are Voltage (V) and Ampere-hours (Ah)?
Voltage (V) refers to the amount of electrical pressure that the battery can provide to the motor. The higher the voltage, the more powerful the motor can be. Most eBike batteries operate on a range of 24 to 52 volts, with the most common being 36V and 48V.
Ampere-hours (Ah) refers to the capacity of electrical charge the battery can hold. The higher the Ah rating, the longer the battery will last on a single charge.
When choosing an eBike battery, it’s important to consider both voltage and Ah to ensure that you have the right combination of power and endurance for your needs. For instance, electric mountain bikes will have much higher voltage than beach cruisers. Similarly, high-performance eRoad bikes will have a much greater Ah than recreational eBikes.
Most Common eBike Batteries to Consider
Each battery size has its own unique advantages and disadvantages, so it’s important to choose the right size based on the type of eBike you ride.
36V 10Ah Battery
The 36V 10Ah battery is one of the most popular eBike battery sizes on the market. It offers a good balance of power and range, making it suitable for most riders. With a voltage of 36V, this battery can provide a decent amount of power to the motor, while the 10Ah capacity ensures that it can last for several hours on a single charge. This battery size is a great choice for commuting and recreational riding, as it provides a good balance of power and range without being too heavy or bulky.
48V 14Ah Battery
The 48V 14Ah battery is a step up from the 36V 10Ah battery in terms of power and range. With a voltage of 48V, this battery can provide more power to the motor, making it ideal for riders who need to tackle steep hills or ride at higher speeds. The 14Ah capacity ensures that the battery can last for several hours on a single charge, making it suitable for longer rides. This battery size is a good choice for riders who need more power and range than the 36V 10Ah battery can offer.
52V 17.5Ah Battery
The 52V 17.5Ah battery is one of the most powerful eBike battery sizes available. With a voltage of 52V, this battery can provide a significant amount of power to the motor, making it ideal for riders who need to tackle extremely steep hills or ride at very high speeds. The 17.5Ah capacity ensures that the battery can last for several hours on a single charge, making it suitable for long-distance rides. However, this battery size is heavier and bulkier than the 36V and 48V options, so it may not be suitable for all riders.
24V 10Ah Battery
The 24V 10Ah battery is a lower-powered option that is suitable for casual riders or those on a budget. With a voltage of 24V, this battery provides less power to the motor than the 36V and 48V options, but it can still provide a decent amount of assistance. The 10Ah capacity ensures that the battery can last for several hours on a single charge, making it suitable for shorter rides. This battery size is a good choice for riders who want an eBike but don’t need a lot of power or range.
72V 20Ah Battery
The 72V 20Ah battery is a high-powered option that is suitable for advanced riders who need maximum power and range. With a voltage of 72V, this battery can provide a significant amount of power to the motor, making it suitable for extreme terrain or high-speed riding. The 20Ah capacity ensures that the battery can last for several hours on a single charge, making it suitable for long-distance rides. However, this battery size is the heaviest and bulkiest option, so it may not be suitable for all riders.
Choosing the right eBike battery size is an important decision that should be based on your individual needs and preferences. The 36V 10Ah and 48V 14Ah batteries are the most popular options, providing a good balance of power and range. The 52V 17.5Ah battery is a more powerful option that is suitable for advanced riders.
