What Are the Key Specifications of the Hailong EBike Battery?

The Hailong battery series supports 36V and 48V configurations, with capacities ranging from 10Ah (360Wh) to 20Ah (960Wh). Built with high-density 18650 cells, it achieves a 1000+ charge cycle lifespan. The battery’s BMS (Battery Management System) ensures overcharge, over-discharge, and short-circuit protection, while its 30A continuous discharge rate sustains high-power Bafang motors.

Which Bafang Motors Are Compatible with the Hailong Battery?

This battery is optimized for Bafang mid-drive and hub motors, including the 500W, 750W, 1000W, and 1500W models. Its XT60 and Anderson connectors ensure universal compatibility. For example, the 48V 20Ah variant provides 1.5 hours of continuous runtime at 1500W output, ideal for aggressive mountain biking or cargo e-bike applications.

How Does Cell Quality Impact Battery Longevity?

The 18650 cells used in Hailong batteries are Grade A Panasonic/Samsung units with ≤1% self-discharge monthly. Each cell undergoes ultrasonic welding to minimize resistance, paired with nickel-plated steel casings to prevent corrosion. This construction enables 80% capacity retention after 800 cycles, outperforming generic Li-ion packs by 40% in lifespan tests.

What Safety Features Prevent Overheating?

A 3-layer safety architecture combines a 32-bit BMS chip, flame-retardant ABS casing, and dual-stage thermal fuses. The system monitors cell temperatures in real-time, throttling output if internal temps exceed 60°C (140°F). Stress tests show the battery sustains 55°C external heat for 2 hours without performance decay or swelling.

Can the Battery Be Used in Extreme Weather?

With an IP65 rating, the Hailong withstands heavy rain, snow, and dust ingress. Its low-temp charging circuit allows operation from -20°C to 60°C (-4°F to 140°F). In sub-zero conditions, the BMS automatically reduces discharge rates by 15% to prevent lithium plating, while summer heat triggers active cooling via aluminum heat sinks.

How Does Voltage Affect Motor Performance?

A 48V Hailong battery increases torque by 33% compared to 36V models when paired with a 1000W Bafang motor. For instance, 48V×20Ah = 960Wh provides 28Nm of torque at 90% efficiency, enabling 35° hill climbs. Voltage sag is limited to 3% under full load, ensuring consistent power delivery during acceleration.

Higher voltage systems reduce current draw for the same power output, minimizing heat buildup in motor windings. For example, a 48V battery running a 1000W motor pulls only 20.8A (versus 27.7A at 36V), reducing resistive losses by 25%. This efficiency gain translates to 5-8% longer range on mountainous trails. Riders tackling technical singletrack benefit from the instantaneous torque response of 48V configurations, which maintain RPM stability even during rapid throttle changes. However, users should ensure their motor controllers support higher voltages to avoid compatibility issues.

Peak Torque	21Nm	28Nm
Range (1500W)	22 miles	29 miles
Charge Time	5.5 hours	7 hours

What Maintenance Maximizes Battery Life?

Store batteries at 50% charge in 15-25°C (59-77°F) environments. Avoid draining below 20% or charging above 90% for daily use. Balance-charge monthly using a 42V/54.6V smart charger (for 36V/48V models). Cleaning terminals with isopropyl alcohol every 500 miles prevents voltage drops from oxidation.

Implementing a partial discharge strategy extends cycle life significantly. Instead of full 100% discharges, keeping usage between 30-80% charge reduces cell stress. For winter storage, maintain batteries at 40% charge and wrap them in thermal blankets if temperatures drop below -10°C. Monthly calibration cycles (full discharge/recharge) help the BMS accurately estimate remaining capacity. Avoid fast charging unless necessary—chargers above 3A accelerate electrode degradation by 15-20% over 500 cycles. Using dielectric grease on connectors every 6 months prevents corrosion in humid environments.

Terminal Cleaning	Every 500 miles	Isopropyl alcohol, brush

BMS Reset	Annually	Factory tool (optional)

Expert Views

“The Hailong’s use of automotive-grade BMS chips sets it apart—most e-bike batteries still rely on cheaper, consumer-grade components. Its ability to handle 2C discharge rates (40A for 20Ah models) makes it a favorite for high-performance trail riding. However, users should prioritize firmware updates for the BMS, as voltage calibration drift can occur after 300 cycles.”

Conclusion

The New Hailong EBike Battery redefines off-road e-biking with its fusion of high-density 18650 cells, ruggedized design, and smart BMS technology. By balancing capacity, voltage, and thermal resilience, it addresses the core demands of Bafang motor enthusiasts while introducing pro-level safety protocols previously unseen in mid-tier battery systems.

FAQs

Q: How long does a full charge take?

A: 36V models charge in 4-5 hours with a 2A charger; 48V 20Ah batteries require 6-7 hours using a 3A charger.

Q: Is the battery airline-approved?

A: No—its 960Wh capacity exceeds the 100Wh limit for cabin luggage. Ground shipping is mandatory.

Q: Can I swap cells myself?

A: Not recommended—tampering voids the warranty and risks BMS incompatibility. Authorized service centers use pre-tested cell batches.
