How Does the Hailong Battery Support High-Power Motors?

The Hailong battery’s 36V and 48V configurations deliver stable voltage output, essential for 500W–1000W motors. Its 20Ah capacity provides sustained energy flow, preventing voltage sag during peak loads. With a 30A continuous discharge rate, it meets the demands of steep inclines and high-speed cycling, ensuring seamless compatibility with Bosch, Bafang, and other popular motor systems.

Modern e-bike motors require not just raw power but consistent energy delivery. The Hailong battery achieves this through precision-engineered cell grouping, which maintains voltage stability even under maximum load. For example, when paired with a 1000W motor climbing a 15% gradient, the battery’s discharge curve shows less than 5% voltage drop, compared to 10–15% in generic packs. This stability translates to smoother acceleration and reduced strain on motor components. Additionally, the battery’s peak discharge capability of 45A for short bursts accommodates sudden power demands, such as overtaking vehicles or navigating rocky terrain. Riders using torque sensors will appreciate the instantaneous response, as the battery’s low internal resistance (≤30mΩ) minimizes latency between pedal input and motor engagement.

Motor Power	Recommended Voltage	Max Range*
500W	36V	55–75 miles
750W	48V	45–65 miles
1000W	48V	35–50 miles

What Are the Advantages of 18650 Lithium-Ion Cells?

18650 cells offer high energy density (250–300Wh/kg), compact size, and proven durability. These cells feature low self-discharge (1–2% monthly) and 500–1,000 charge cycles. The Hailong pack uses grade-A Panasonic/Samsung cells, coupled with a Battery Management System (BMS) for balanced charging, overcurrent protection, and temperature control, enhancing safety and lifespan.

The cylindrical design of 18650 cells allows efficient heat dissipation, a critical factor in high-drain applications. Unlike prismatic cells, which can develop hot spots, 18650s distribute thermal load evenly across their surface. This design, combined with nickel-plated steel casings, enables stable operation at temperatures up to 60°C. For longevity, the Hailong pack employs a hybrid cathode material (NMC with LiFePO4 coating), which reduces oxidative stress during deep discharges. Users can expect 80% capacity retention after 800 cycles when operated within the recommended 20–80% charge window. Furthermore, the cells’ standardized size simplifies recycling processes, aligning with eco-friendly disposal practices. In stress tests, these cells withstand 200% overcharge scenarios without venting, thanks to their integrated CID (Current Interrupt Device) safety valves.

How Far Can You Travel on a Single Charge?

A 48V 20Ah Hailong battery provides 960Wh, enabling 50–70 miles per charge on a 750W motor, depending on terrain, rider weight, and assist level. Eco mode extends range by 20%, while throttle-only usage reduces it. Factors like tire pressure, wind resistance, and ambient temperature (optimal: 15°C–25°C) further influence real-world performance.

Why Choose a Hailong-Style Battery Pack?

The Hailong design features a streamlined, lock-and-key casing that integrates neatly with bike frames. Its IP65 rating protects against dust and water splashes, while the ergonomic shape simplifies installation. The pack’s modular design allows easy cell replacement, reducing long-term costs. Pre-soldered XT60 connectors ensure compatibility with most e-bike systems without requiring adapters.

What Safety Features Are Integrated into the Battery?

Beyond the BMS, the battery includes short-circuit prevention, flame-retardant casing (UL94 V-0 certified), and multi-layered cell insulation. Charging safeguards halt power input at 90% capacity to avoid overcharging, while low-temperature cutoffs (-10°C) prevent cold-weather damage. Each unit undergoes UL, CE, and RoHS testing for compliance with international safety standards.

How Does Fast Shipping Enhance the Purchase Experience?

“The Hailong battery’s blend of 18650 cells and smart BMS addresses the core challenges of e-bike energy storage: weight, range, and safety. Its modularity allows users to replace individual cells, extending the pack’s life beyond typical 3–5-year spans. For high-torque applications, the 48V 20Ah variant is unmatched in balancing power and portability.” — E-Bike Industry Engineer

Conclusion

The Hailong Li-ion EBike Battery stands out for its adaptability to high-wattage motors, robust 18650 cell architecture, and thoughtful safety engineering. Whether for daily commutes or adventurous trails, its combination of range, durability, and rapid delivery makes it a top contender in the e-bike battery market.

FAQ

Q: How long does the battery take to charge fully?

A: A 48V 20Ah battery charges in 5–7 hours with a standard 2A charger. Fast chargers (4A) reduce this to 3–4 hours.

Q: Is the battery compatible with regenerative braking systems?

A: No, the Hailong pack lacks regenerative charging capabilities due to its BMS configuration.

Q: What warranty is provided?

A: Most sellers offer a 12-month warranty covering manufacturing defects and capacity drops below 80% within 500 cycles.
