The New Hailong EBike Battery optimizes performance for Bafang motors (500W-1500W) through its 36V/48V voltage options, 18650 lithium cells, and smart BMS. With capacities up to 20Ah, it delivers extended range, thermal stability, and compatibility across mountain/road e-bikes. Its modular design allows easy integration with Bafang mid-drive/hub systems while meeting UL/CE safety standards.
What Is a DC to DC Lithium Battery Charger and How Does It Work
What Safety Features Protect the Hailong Battery During High-Power Use?
Triple-layer protection includes:
1) Grade A Panasonic/Sanyo cells with explosion-proof vents
2) IP67 waterproof casing resistant to vibration/shock
3) 16-bit BMS monitoring temperature, short circuits, and overcharge (cutoff at 4.25±0.05V/cell). Thermal runaway prevention activates at 149°F (65°C), with cell-level fuses isolating faults within 0.1 seconds.
| Safety Component | Specification | Response Time |
|---|---|---|
| Overcharge Protection | 4.25V ±0.05V cutoff | <50ms |
| Thermal Sensors | 3 per cell group | Continuous monitoring |
| Short Circuit Protection | 300A interrupt capacity | <100μs |
The battery’s aluminum alloy casing undergoes rigorous stress testing, capable of withstanding 200kg static loads without deformation. This structural integrity is crucial for off-road applications where impacts are common. The multi-stage thermal management system uses phase-change materials between cells to absorb heat during 1500W discharges, maintaining cell temperatures below 113°F (45°C) even in 95°F ambient conditions.

How to Choose Between 10Ah, 15Ah, and 20Ah Capacities?
Select capacity based on:
– 10Ah: 25-30 mile range (500W motors, 165lbs load)
– 15Ah: 40-45 miles (750W, 200lbs)
– 20Ah: 55-60 miles (1000W+, 250lbs). Higher Ah increases weight (5.5lbs vs 9.7lbs) – critical for MTB handling. 20Ah models use 21700 cells for 25% greater energy density vs standard 18650 packs.
DEESPAEK 12V 200Ah LiFePO4 Battery for RV, Solar, and Trolling Motor Use
| Capacity | Weight | Ideal Usage | Charge Cycles |
|---|---|---|---|
| 10Ah | 5.5 lbs | Urban commuting | 1000+ |
| 15Ah | 7.1 lbs | Trail riding | 900+ |
| 20Ah | 9.7 lbs | Expedition touring | 800+ |
For cargo e-bikes or tandem riders, the 20Ah variant provides necessary endurance despite its weight penalty. The 21700 cells in premium models deliver 5,000mAh per cell versus 3,500mAh in standard 18650 cells, enabling compact packaging. Riders prioritizing agility should consider 10Ah packs – their 2.6kg weight saves 43% mass compared to 20Ah units, significantly improving trail bike maneuverability.
“The Hailong’s multi-tiered BMS is a game-changer. By implementing cell-level voltage monitoring and dynamic current redistribution, it prevents the ‘weakest link’ effect that plagues budget packs. For Bafang users pushing 1500W, this translates to 18-24 months of reliable service even with daily heavy loads.”

FAQs: Hailong EBike Battery Technical Considerations
- Q: Can I charge Hailong batteries with solar panels?
- A: Yes, using a 100W+ solar charger with 42V/54.6V CVCC output. Requires MPPT controller for optimal efficiency.
- Q: How to store batteries during winter?
- A: Keep at 40-80% charge in dry, 50-77°F conditions. Avoid temperatures below 14°F (-10°C).
- Q: Warranty coverage for Bafang compatibility issues?
- A: 2-year warranty covers BMS/connector defects but not motor compatibility mismatches – confirm voltage/connector type before purchase.
