When considering the transition to electric cycling, one of the most critical components of any conversion kit is the battery. The 36V 13AH Rear Rack Ebike Battery stands out as a robust option for riders seeking to upgrade their traditional bicycles to electric power. Designed for compatibility with motors ranging from 250W to 750W, this lithium-ion battery offers a blend of performance, safety, and practicality, making it a compelling choice for both casual commuters and enthusiasts tackling longer journeys.
Technical Specifications and Compatibility
At its core, the battery’s 36V 13AH configuration delivers ample power for a wide range of cycling applications. Constructed with top-tier A-grade cells, it boasts a maximum constant discharge current of 20A, ensuring stable energy delivery even under demanding conditions. The inclusion of a 42V 2A charger allows for a full recharge in approximately 6–7 hours, with a claimed range of 30–40km per charge. However, real-world mileage will naturally vary depending on factors such as rider weight, terrain gradient, and motor efficiency.
The battery’s dimensions (440 x 155 x 63mm) and lightweight aluminium casing make it suitable for 24” to 28” wheel conversion kits. Its compatibility with popular discharge connectors, including Anderson and XT60 (both male and female variants), ensures seamless integration with most motor systems. Riders have noted its adaptability, with one user highlighting the convenience of fitting a controller within the rear casing, albeit with a caveat: “Just needed to make cables shorter as it’s limited space there.” This feedback underscores the importance of careful planning during installation, particularly for those incorporating additional components.
Design and Practical Features
A standout feature of this battery is its integrated taillight, which enhances visibility during low-light conditions. This thoughtful addition addresses a common oversight in aftermarket e-bike components, where safety features are often secondary to core functionality. The built-in battery indicator is another practical touch, enabling riders to monitor charge levels and plan recharging cycles effectively.
The aluminium shell not only contributes to durability but also simplifies transportation. Its sleek, modern design ensures unobtrusive integration with most bicycle frames, while the absence of an included rack (as clarified in the product description) allows users to select mounting solutions tailored to their specific setup. For cyclists prioritising ease of assembly, the straightforward installation process has been praised, with users describing it as “very easy to assemble” despite the need for minor cable management adjustments.
Performance and Longevity
With a claimed lifespan of up to five years and over 1,000 charge cycles while retaining ≥80% capacity, this battery positions itself as a long-term investment. The integration of a 20A Battery Management System (BMS) provides critical safeguards against over-charging, over-discharging, and short circuits. Such protections are essential for maintaining cell integrity, particularly in variable weather conditions common to UK cycling environments.
Riders appreciate the balance between energy density and weight, with the 13AH capacity offering sufficient endurance for daily commutes without introducing excessive bulk. The 2A charger, while not the fastest on the market, prioritises cell longevity over rapid charging—a trade-off that aligns with the product’s emphasis on durability.
Safety and Certification
Compliance with CE, ROHS, and MSDS certifications underscores the manufacturer’s commitment to safety and environmental responsibility. These standards ensure the battery meets rigorous EU regulations concerning hazardous substances and occupational health protocols. For UK-based cyclists, the inclusion of a 12-month warranty and lifetime technical support provides additional peace of mind, particularly when navigating the complexities of aftermarket e-bike conversions.
User Experience and Feedback
Feedback from riders emphasises the product’s value proposition, with multiple references to its affordability relative to performance. One user summarised their experience: “Great battery for affordable price!”—a sentiment reflecting the balance between cost and capability that defines this product. The availability of UK warehouse distribution eliminates import delays and potential customs complications, a crucial consideration for time-sensitive projects.
While space constraints within the casing have been noted, this appears to be a minor consideration rather than a fundamental flaw. The requirement for cable shortening, as mentioned in user reviews, suggests a need for basic DIY skills but falls well within the capabilities of most cycling enthusiasts undertaking conversion projects.
Environmental and Practical Considerations
The shift toward e-bike conversions aligns with broader sustainability trends in urban mobility. By enabling the repurposing of existing bicycles, this battery contributes to reducing electronic waste compared to purchasing complete new e-bike systems. The lithium-ion chemistry offers a favourable energy-to-weight ratio compared to older battery technologies, while the recyclable aluminium casing further supports eco-conscious cycling practices.
For commuters navigating hilly routes or carrying cargo, the 20A discharge rate ensures consistent power delivery even under load. The battery’s thermal management properties, inherent in its aluminium housing, help dissipate heat during extended use—a critical factor in maintaining performance during summer months or prolonged climbs.
Conclusion
The 36V 13AH Rear Rack Ebike Battery emerges as a versatile solution for cyclists seeking to embrace electric assistance without compromising on reliability or safety. Its combination of certified protections, user-friendly design, and adaptable compatibility makes it particularly suited to the UK market, where varied terrain and weather conditions demand robust performance. While requiring some mechanical aptitude for optimal installation, the product rewards users with dependable power delivery and longevity.
For those undertaking conversion projects on 26”–28” wheel bicycles, this battery provides a balanced foundation upon which to build a tailored e-bike system. The integration of safety features like the BMS and taillight demonstrates a manufacturer’s understanding of real-world cycling needs, bridging the gap between technical specifications and practical usability.
