The SEASON Hailong Ebike Battery represents a versatile and robust power solution for electric bicycle enthusiasts seeking enhanced range and reliability. Designed to accommodate a broad spectrum of motor configurations, this down-tube-mounted battery system combines practical engineering with user-centric features, making it a compelling choice for both casual riders and commuters. Below, we delve into its technical specifications, real-world performance, and the experiences shared by users who have integrated it into their cycling setups.
Technical Specifications and Compatibility
At its core, the SEASON Hailong Ebike Battery is available in multiple configurations to suit varying power requirements. The 36V models offer capacities of 13Ah, 15.6Ah, and 17.4Ah, while the 48V variant provides 12.5Ah, ensuring compatibility with motors ranging from 100W to 1000W. This flexibility is a significant advantage for riders upgrading older systems or customising newer builds. The inclusion of a 35A Battery Management System (BMS) ensures stable operation, safeguarding against overcharge, over-discharge, and short circuits.
Constructed using DMEGC-29E 2900mAh cells, the battery emphasises longevity, with a claimed lifespan exceeding 1,000 charge cycles. Users have noted its ability to maintain consistent voltage output even under load, a critical factor for maintaining motor efficiency during climbs or prolonged use. The USB port adds convenience for charging devices on the go, a feature appreciated by commuters and touring cyclists.
Real-World Performance and User Feedback
One of the standout attributes highlighted by riders is the battery’s extended range. A user transitioning from a four-year-old 9Ah battery reported a dramatic improvement, noting that even after 15 miles of mixed terrain, the battery still indicated a full charge. This aligns with SEASON’s claim of a “maximum range” design, facilitated by its 644Wh capacity (for the 36V 17.4Ah model). The extended range is particularly beneficial for those tackling longer commutes or recreational rides where access to charging points may be limited.
Charging times, while not the fastest on the market, are consistent with expectations for high-capacity lithium-ion systems. The six-hour full charge cycle has been described as a reasonable trade-off for the battery’s endurance. Riders emphasised the importance of initiating a full charge upon delivery to optimise cell performance—a step reinforced by the manufacturer’s guidelines.
Installation experiences vary slightly depending on the bicycle’s existing setup. Some users encountered challenges with wire length during cradle attachment, particularly when retrofitting older frames. However, improvisation and careful routing resolved these issues, and once secured, the battery’s down-tube placement received praise for its stability and low centre of gravity. The weight—approximately 4kg for the 15.6Ah model—was acknowledged as a consideration but deemed acceptable given the performance gains.
Durability and Support
Certifications such as CE, ROHS, and UN38.3 underscore the battery’s compliance with safety and environmental standards. Users highlighted the robust construction, with one noting its resilience to daily commuting demands, including vibration and minor impacts. The 18-month warranty on the battery (12 months for the charger) provides additional reassurance, while SEASON’s UK-based warehouse ensures prompt delivery and access to local repair services—a critical factor for minimising downtime.
Practical Applications
The SEASON Hailong Ebike Battery excels in scenarios requiring dependable power over extended periods. For urban commuters, the combination of range and USB functionality supports uninterrupted journeys. Leisure riders appreciate the confidence to explore without range anxiety, while those upgrading older e-bikes benefit from its compatibility with common motor kits. A user replacing an obsolete frame-integrated battery praised the Hailong’s adaptability, stating it “gives you a good range and comes with all you need to fit it.”
Conclusion
Balancing capacity, compatibility, and user-friendly design, the SEASON Hailong Ebike Battery stands out as a pragmatic upgrade for electric bicycle owners. Its emphasis on longevity and safety, coupled with tangible improvements in range, makes it a worthwhile investment for enhancing ride quality. While minor installation adjustments may be necessary for certain frames, the consensus among users is clear: this battery delivers on its promises, revitalising older systems and empowering new adventures.
