为您的电动自行车业务提供动力：正确选择电池指南

In the electric bicycle industry, the battery is the core power source of the entire vehicle. Its performance, lifespan, and safety directly affect user experience and brand reputation. Whether you are a brand owner, distributor, or custom vehicle manufacturer, choosing the right battery is crucial for success.

This article provides a comprehensive guide to help businesses efficiently select the right battery solution and provide reliable power for business development.

Part 1.The Importance of Battery Selection

Electric bicycle batteries not only determine the vehicle’s range and power performance but also affect safety, overall vehicle lifespan, and after-sales service costs. Choosing the wrong battery can lead to:

Insufficient power or inability to climb hills

Shortened battery life or low cycle count

Frequent BMS protection triggering

Potential safety hazards (over-discharge, overcharge, short circuit)

Therefore, when purchasing or customizing batteries, businesses must consider factors such as voltage, capacity, cell quality, BMS intelligent protection, and brand certification.

Part 2.Analysis of Core Battery Parameters

电压

Voltage determines the motor output power and speed matching:

36V system: Suitable for short to medium-distance commuting and light-load users

48V system: Suitable for long-range, hill climbing, or high-load models

60V system: Suitable for high-performance, high-speed, or high-power transport models

容量（Ah）

Capacity determines the riding range:

Higher capacity means longer riding distance per charge

Insufficient capacity leads to short range and poor customer experience

Needs to be matched with motor power and voltage to avoid over-discharge

(Illustration suggestion: Insert a “Capacity vs. Riding Range Comparison Chart,” showing the range differences of different capacity batteries on different models.)

电池类型

Cylindrical Cells (18650/21700): High energy density, suitable for long lifespan and high power requirements

Prismatic Cells: Easy to assemble, high safety

Pouch Cells (LiPo): Lightweight design, suitable for lightweight vehicles

BMS Intelligent Protection System

BMS (Battery Management System) is a crucial system for ensuring battery safety and extending lifespan. Its main functions include:

过充电/过放电保护

短路保护

Temperature monitoring and thermal management

Battery balancing

Data logging and communication

Part 3.Key Factors in Choosing a Battery Supplier

Company qualifications and industry experience

ISO9001/14001 certification

EN50604, UL, CE and other international certifications

More than 10 years of experience in lithium battery R&D and manufacturing

Customization capabilities (OEM/ODM)

Voltage, capacity, and appearance customization

Private label and packaging

Technical consulting and complete vehicle matching solutions

质量控制系统

Cell screening, PACK assembly, factory testing

Cycle life testing, aging testing

Intelligent BMS debugging

Supply chain stability

Large-scale production capacity

Delivery time and logistics management

After-sales service and technical support

Part 4.Suggested Enterprise Procurement Process

Clarify complete vehicle design requirements: voltage, capacity, range, appearance

Sample testing: Verify performance, range, and BMS functions

Sign contracts and warranty terms: Clarify MOQ, price, payment methods, and warranty period

Production and quality monitoring: Random inspection, third-party factory inspection

Logistics and transportation: Lithium batteries are dangerous goods and require UN38.3, MSDS documents and labels

Part 5.Case Comparison: The Impact of Different Battery Choices on Business

Conclusion: Matching capacity and voltage to the vehicle design is key to improving customer experience and brand competitiveness.

FAQ (Frequently Asked Questions)

Q1: Can batteries from different brands be mixed?

Answer: Even if the specifications are the same, batteries from different brands may have different cells, BMS, and safety standards. Mixing them is not recommended.

Q2: How to determine battery life and cycle times?

Answer: Refer to the cell manufacturer’s specifications and the cycle life test report provided by the manufacturer. Yizhan Electronics batteries have a cycle life of over 1000 cycles and stable performance.

Q3: What services are included in OEM/ODM customization?

Answer: Voltage, capacity, cell type, casing design, brand labeling, packaging, and vehicle integration technical support.

Q4: Can low-voltage batteries improve overall vehicle performance?

Answer: Low-voltage batteries cannot improve overall vehicle performance; on the contrary, they may reduce power output and range, and even trigger BMS protection.

Q5: How to ensure the safety and reliability of purchased batteries?

Answer: Choose qualified suppliers, confirm BMS intelligent protection and international certifications, request samples for testing, and sign warranty terms.

Choosing the right electric bicycle battery is a core element in improving overall vehicle performance, customer experience, and brand competitiveness. When purchasing, companies must consider voltage, capacity, cell type, BMS functions, and supplier qualifications.
