Exploring the Application of 18650 Batteries in E-Bikes

Yuyuan Zhu

With the continuous progress of technology, electric bicycles are becoming a popular means of transportation in modern cities. Among the core components of electric bicycles, the 18650 battery, as the power source, has become one of the popular choices in the field of e-bikes. This article will explore the characteristics and advantages of 18650 batteries, helping you gain a better understanding of the 18650 battery.

What is 18650 Battery

18650 battery is a lithium-ion battery with dimensions of 18mm in diameter and 65mm in length. 0 represents a cylindrical battery, hence it is called 18650. This type of battery is known for its high energy density, long lifespan, and stability, making it the preferred choice in many fields, the electric bicycle industry is no exception.


The 18650 battery has undergone quality control and testing, with high reliability and stability, and can operate normally under different environmental conditions. People can use 18650 batteries with confidence without worrying too much about safety issues.

Long Service Life

The 18650 battery has a long cycle life and can theoretically be recharged and discharged 1000 times, maintaining excellent performance and extending the battery's service life. This is particularly important for electric bicycles as they typically require frequent charging and discharging.

The 18650 battery also has the characteristic of no memory effect. The no memory effect of batteries refers to the use of battery capacity without the need for complete discharge or charging during normal use and charging processes.

Traditional nickel cadmium batteries have a memory effect, and frequent incomplete discharge and charging can lead to a gradual decrease in battery capacity. A battery without memory effect can better maintain battery capacity and performance, and extend the battery's service life. Users can flexibly charge as needed, thereby improving charging efficiency and usage time.

High Energy Density

Compared to traditional lead-acid batteries, the 18650 battery has a higher energy density and can store more electrical energy in a relatively small volume, providing longer range.

The 18650 battery provides a stable and reliable current output, which can meet the power needs of electric bicycles and drive their motors to meet daily travel needs.

How to Choose a Suitable 18650 Battery

  1. Capacity and Voltage

Based on the needs and usage of electric bicycles, choose the appropriate battery capacity and voltage to meet the required range and power output.

  1. Brand and Quality

Choose 18650 batteries from formal manufacturers to ensure product quality and after-sales service, and avoid safety hazards and usage issues caused by the use of low-quality batteries.

  1. Protection Function

Choose 18650 batteries with multiple protection functions, including overcharge protection, over discharge protection, over current protection, etc., to improve the safety and stability of the battery.

Maintenance and Safe Use

  1. Charge and Discharge

Follow the manufacturer's charging and discharging requirements, use suitable chargers and charging devices to avoid overcharging and discharging, extend battery life, and ensure safety.

  1. Temperature Control

Avoid prolonged exposure of the battery to extreme high or low temperatures, maintain a suitable operating temperature range, and avoid battery performance degradation or damage.

  1. Regular Inspection

Regularly inspect the appearance and connectors of the battery to ensure that there are no abnormalities, and promptly identify and solve potential problems.

  1. Safe Storage

If an electric bicycle is not used for a long time, the battery should be stored in a dry, ventilated, and cool place to avoid moisture or excessive discharge.


The 18650 battery has advantages such as high energy density and long lifespan, making it a reliable power source for e-bikes and playing an important role in the field of electric bicycles.
