Dongguan Yizhan Electronics Technology Co., Ltd. , a leading manufacturer of customized lithium battery solutions, proudly announces that its latest series of eBike batteries have successfully passed UL and EN50604 certifications. This achievement demonstrates Yizhan’s unwavering commitment to safety, performance, and compliance with both U.S. and European regulatory standards, ensuring global customers reliable battery solutions for electric bicycles.
The newly certified product lines include 36V and 48V batteries, available in down tube, inner tube, and rear rack configurations, offering flexible integration options for a wide range of eBike models.
As the eBike industry continues its rapid growth across the U.S. and Europe, certification has become a key market entry requirement.
UL Certification (United States): UL standards, especially UL 2271 and UL 2849, are among the most recognized benchmarks for lithium battery safety in the American market. Passing UL testing assures users of electrical safety, thermal stability, fire resistance, and robust BMS (Battery Management System) protections.
EN50604 Certification (European Union): EN50604 is the official EU standard for lithium-ion traction batteries, particularly for light electric vehicles such as eBikes. Compliance with EN50604 ensures that batteries are tested under stringent European safety and performance criteria, covering aspects such as overcharge, short circuit, vibration, mechanical shock, and waterproofing.
By achieving both certifications, Yizhan positions itself as a globally trusted supplier of high-quality eBike batteries that meet the strictest international standards.
Product Line Overview: Flexible Solutions for Modern eBikes
1. 36V and 48V Down Tube Batteries
Down tube batteries are the most common choice for mid-to-high-end eBikes. Mounted on the bicycle frame’s down tube, they provide a balanced weight distribution, enhancing both performance and riding comfort.
– Voltage Options: 36V for standard city and commuter bikes; 48V for high-performance and mountain eBikes.
– Smart BMS Integration: Real-time monitoring of voltage, current, temperature, and cycle life.
– Design Benefits: Sleek, aerodynamic casing with enhanced waterproofing (IP65+), suitable for outdoor use in diverse climates.
– Applications: City commuters, mountain bikes, hybrid eBikes.
2. 36V and 48V Inner Tube Batteries
Inner tube batteries are compact solutions that fit seamlessly inside the bicycle frame, making them nearly invisible to the rider.
– Hidden Design: Integrated inside the frame tube, creating a clean aesthetic and protecting the battery from external impact.
– Lightweight Build: Optimized for urban eBikes where weight reduction is critical.
– Safety Advantage: Shielded from dust, water, and mechanical damage, extending overall service life.
– Applications: Folding eBikes, city bikes, compact commuter eBikes.
3.36V and 48V Seat Tube batteries
have successfully passed EN50604 and UL certifications, ensuring compliance with both European and U.S. safety standards. Designed for seamless integration into the bicycle seat tube, these batteries combine compact structure, reliable performance, and enhanced waterproof protection, making them a safe and durable choice for modern eBikes in global markets.
Safety and Reliability: Built Into Every Battery
Beyond certifications, Yizhan has implemented a multi-layered safety framework in its battery designs:
1. Advanced Battery Management System (BMS):
– Overcharge/over-discharge protection
– Overcurrent and short-circuit protection
– Temperature control with thermal cutoff mechanisms
2. Enhanced Waterproofing & Dustproofing:
– Achieves IP65–IP67 protection levels, ensuring safe operation in rain, snow, and muddy terrains.
3. Reinforced Structural Design:
– Thicker casings and internal support pillars protect against mechanical shock and vibration.
4. Cycle Life & Performance Stability:
– Over 800–1000 charge cycles, maintaining high capacity retention and consistent performance.
Market Impact: Driving eBike Adoption in the U.S. and EU
With increasing green mobility policies in the U.S. and European Union, the demand for certified, safe, and reliable eBike batteries is at an all-time high.
– United States: Many states now require UL-certified batteries for eBike imports and sales. By meeting UL standards, Yizhan ensures its products are market-ready across the entire U.S. market.
