Electric bicycles are changing how we move in cities, enjoy leisure rides, and handle last-mile transport. Battery performance is now a key factor in product quality, safety, and user satisfaction. Among all voltage options, 36V eBike 배터리 are one of the most popular choices worldwide. They offer a good balance of efficiency, safety, compatibility, and cost.
However, selecting the right 36V battery is not as simple as choosing a voltage and capacity. Battery chemistry, BMS design, structural engineering, certifications, and manufacturing capability all play decisive roles in the long-term success of an eBike product.
Dongguan Yizhan Electronics Co., Ltd. is a professional lithium battery pack manufacturer. We share this 36V eBike battery buying guide. It helps international buyers, OEM brands, and system integrators make smart and future-proof choices.
1. 36V eBike 배터리란 무엇인가요?
A 36V eBike battery typically consists of 10 lithium-ion cells connected in series (10S configuration). The nominal voltage is 36V, while the fully charged voltage reaches approximately 42V.
This voltage platform has become an industry standard for:
- City commuter eBikes
- Folding electric bicycles
- Lightweight pedal-assist bicycles
- Shared mobility and rental fleets
Its widespread adoption ensures high compatibility with motors, controllers, and chargers available worldwide.
2. Why Choose a 36V Battery System?
From Yizhan Electronics’ project experience, the popularity of 36V systems is driven by several key advantages:
- High safety margin compared to higher voltage platforms
- Mature supply chain with stable components and accessories
- Easier compliance with international regulations
- Balanced performance for daily riding needs
- Lower system cost for entry-level and mid-range eBikes
For many brands, a well-designed 36V battery offers the best balance between user experience and manufacturing efficiency.
3. Typical Applications of 36V eBike Batteries
3.1 Urban Commuter eBikes
Designed for daily travel, these bikes prioritize reliability, moderate range, and long service life. A 36V battery easily meets these requirements.
3.2 Folding eBikes
Compact size and weight reduction are essential. A 36V battery enables lightweight designs without sacrificing usability.
3.3 Shared and Rental eBikes
Standardized voltage systems reduce maintenance complexity and simplify fleet management.
3.4 Entry-Level and Mid-Range Product Lines
36V batteries allow brands to control costs while delivering consistent performance.
4. Understanding Capacity: Ah vs. Wh
Battery capacity is commonly expressed in ampere-hours (Ah) 또는 watt-hours (Wh). Wh provides a more accurate comparison because it accounts for voltage.
Common 36V Configurations:
- 36V 7Ah–10Ah (250–360Wh): short commutes, lightweight bikes
- 36V 12Ah–14Ah (430–500Wh): mainstream city riding
- 36V 15Ah–20Ah (540–720Wh): long-distance commuting
Key Considerations When Selecting Capacity:
- Motor power rating
- Rider weight and load
- Riding terrain
- Assist level usage
- Long-term capacity degradation
At Dongguan Yizhan Electronics, we recommend selecting capacity based on real-world usage scenarios rather than theoretical range claims.
5. Battery Cell Chemistry Options
5.1 Lithium-ion (NCM / NCA)
Advantages:
- 높은 에너지 밀도
- 가볍고 컴팩트한 디자인
- Ideal for modern eBike designs
Typical Use Cases:
- Consumer eBikes
- Folding and urban models
- Brands focusing on design and portability
5.2 Lithium Iron Phosphate (LiFePO₄)
Advantages:
- 뛰어난 열 안정성
- 더 길어진 주기 수명
- Enhanced safety characteristics
Considerations:
- Larger size for the same capacity
- Lower energy density
Yizhan Electronics supports multiple cell chemistries and performs strict cell grading, matching, and aging tests before pack assembly.
6. The Importance of a Reliable BMS
The Battery Management System (BMS) is the intelligence center of a 36V eBike battery. A well-designed BMS protects both the battery and the end user.
Core BMS Functions Include:
- 과충전 방지
- 과방전 방지
- Overcurrent and short-circuit protection
- 온도 모니터링
- 셀 밸런싱
For advanced projects, Yizhan Electronics provides custom BMS solutions. These include communication protocols like UART or CAN for smart eBike systems and fleet management.
7. Battery Pack Structure and Mechanical Design
Performance is not defined by cells alone. Mechanical design plays a crucial role in durability and safety.
Key Structural Elements:
- Housing material (aluminum or flame-retardant plastic)
- Internal shock-absorbing structures
- Waterproof sealing design
- Thermal management layout
Before mass production, Yizhan Electronics conducts:
- 진동 테스트
- 낙하 테스트
- 방수 테스트
- High- and low-temperature cycling
These procedures ensure stable performance under real riding conditions.
8. Waterproofing and Environmental Protection
Ebike batteries are exposed to rain, dust, and temperature variations. A well-designed 36V battery typically achieves IPX4 to IPX6 protection depending on application needs.
Proper sealing, connector selection, and venting design help extend battery lifespan and reduce failure rates in outdoor environments.
9. Certifications and Compliance for International Markets
Compliance is essential for global distribution. Common requirements include:
- UN38.3 for transportation
- IEC 62133
- EN 50604 for European eBikes
- CE marking
- UL standards for North America
Dongguan Yizhan Electronics provides certification support from prototype testing to mass production, helping customers reduce time-to-market risks.
10. How to Choose the Right 36V eBike Battery Manufacturer
A reliable supplier should demonstrate:
- In-house R&D and engineering capability
- Stable and traceable cell sourcing
- Standardized quality control procedures
- Scalable mass-production capacity
- Long-term technical and after-sales support
While pricing is important, battery quality directly affects brand reputation, warranty cost, and user safety.
