Dual-Battery eBike Solution | EN50604-Certified

The global eBike industry has experienced explosive growth in recent years, driven by the increasing demand for eco-friendly mobility, rising fuel costs, and advances in lithium battery technology. As consumers demand longer ranges, higher performance, and safer battery systems, manufacturers are challenged to design innovative solutions that meet these expectations.

Dongguan Yizhan Electronics Technology Co., Ltd. a leading lithium battery pack manufacturer in China, has recently launched its dual-battery eBike design solution. This breakthrough enables riders to double their available capacity while ensuring safety and reliability through EN50604-certified lithium battery packs, a certification standard specifically for light electric vehicle (LEV) batteries in Europe.

The Rising Demand for Long-Range eBikes

As electric bicycles continue to transition from urban commuting vehicles to versatile transportation solutions for travel, logistics, and adventure riding, battery capacity and endurance have become critical factors for consumers. Riders no longer view eBikes as short-distance alternatives; instead, they demand:

– Extended range of 100 km or more per charge.
– Faster charging to minimize downtime.
– Reliable safety standards, especially in high-power applications.
– Scalable power options, such as modular or dual-battery systems.

Many traditional single-battery eBike designs face challenges in balancing compact size with high capacity. Yizhan Electronics’ dual-battery solution addresses this issue directly, offering riders the flexibility to carry two fully functional batteries within one eBike system.

– This modular approach supports diverse eBike applications such as delivery services, touring, and off-road riding.

5. Durable Design
– Yizhan integrates reinforced casing, waterproof sealing (IPX5–IPX7 options), and shock resistance to adapt to real-world road conditions.

Yizhan launches a dual battery solution, combining internal tube battery and external battery to make electric bicycles last longer.

EN50604 Certification: Guaranteeing Safety and Reliability

One of the most important aspects of Yizhan’s dual-battery solution is that all packs have successfully passed the EN50604 certification test.

What is EN50604?
EN50604 is a European safety standard designed specifically for rechargeable battery systems used in light electric vehicles such as eBikes, eScooters, and other small EVs. It covers:
– Thermal stability and performance under extreme conditions.
– Electrical safety, including overcharging and short-circuit prevention.
– Mechanical durability under vibration, impact, and drop conditions.
– Environmental resistance, such as waterproof and dustproof performance.

By meeting this certification, Yizhan ensures that its batteries are not only compliant with European Union regulations but also trusted by global eBike brands seeking entry into the European market.

For global eBike brands and OEM (Original Equipment Manufacturers), partnering with Dongguan Yizhan Electronics Technology Co., Ltd offers multiple advantages:

1. Market Entry Compliance
– EN50604 certification ensures smooth access to European markets, reducing regulatory hurdles.

2. Customization Options
– Yizhan provides tailored solutions for voltage (36V, 48V, 52V, 60V), capacity, and form factor.
– Design can be adapted for down-tube batteries, inner-tube batteries, or rear-rack packs.

3. Faster Time-to-Market
– Ready-to-implement dual-battery designs allow eBike brands to quickly integrate advanced features into their product lines.

4. Enhanced Brand Value
– Offering dual-battery options helps manufacturers position themselves as premium, long-range eBike providers.

5. After-Sales Reliability
– EN50604-tested batteries reduce warranty risks, giving OEMs peace of mind and lowering after-sales service costs.

Applications of the Dual-Battery System

The versatility of Yizhan’s solution makes it suitable for different eBike categories:
