The 48V 1000W Hailong ebike battery combines high energy density, durable lithium-ion cells, and smart BMS protection for extended range and reliability. Designed for e-bikes requiring sustained power output, it features a compact form factor, 2-3 hour charging time, and compatibility with most mid-drive/hub motors. Its modular design allows easy replacement of individual cells.
How Does the Hailong Battery Design Enhance Ebike Performance?
The horizontal tube-shaped configuration lowers the bike’s center of gravity, improving handling during high-speed rides. With 18650 cells arranged in 13S4P configuration, it delivers stable 48V output even under 1000W load. The aluminum alloy casing acts as heat sink, maintaining optimal temperatures during rapid discharge cycles.
What Safety Features Protect the 48V 1000W Hailong Battery?
Triple-layer protection includes:
1) Cell-level fuses preventing thermal runaway
2) BMS with overcharge/discharge cutoff
3) Pressure relief vents in casing
4) Short-circuit protection reacting in 0.01 seconds
5) Waterproofing to IP65 standards. The system automatically limits output if internal temps exceed 60°C (140°F).
Which Ebike Models Are Compatible With This Battery?
Compatible with:
– Bafang M620/M600 mid-drives
– Shimano STEPS E8000 systems
– Bosch Performance Line (via adapters)
– 90% of hub motors using Hailong connectors
Note: Requires controller supporting 35-50A continuous discharge. Check voltage compatibility with motor specifications before installation.
| Ebike Model | Adapter Required | Max Discharge |
|---|---|---|
| Bafang M620 | No | 45A |
| Bosch Performance CX | Yes | 40A |
| Shimano EP8 | No | 50A |
For non-listed models, verify connector type and voltage requirements. The battery’s XT60 connector works with most aftermarket kits when using appropriate wiring harnesses. Specialized mountain ebikes may require custom mounting brackets due to the Hailong’s 385mm length.
How Does Temperature Affect Battery Efficiency?
Performance drops by 12% at 0°C (32°F) and 18% at 40°C (104°F). Use insulated covers below freezing. Avoid direct sunlight exposure – every 10°C above 25°C halves cycle life. The BMS automatically reduces max current by 0.5A/°C beyond 45°C to prevent damage.
| Temperature Range | Efficiency | Recommended Action |
|---|---|---|
| -10°C to 0°C | 50-70% | Pre-warm battery indoors |
| 15°C to 35°C | 100% | Normal operation |
| 40°C+ | 82% | Reduce discharge rate |
Lithium-ion cells experience increased internal resistance in cold conditions, requiring smart preconditioning through battery management systems. Riders in extreme climates should consider thermal wraps and avoid fast charging when ambient temperatures exceed 38°C.
“The Hailong’s modularity changes ebike economics. Where competitors force full battery replacements, this system allows cell-by-cell refurbishment. We’ve seen packs last 6+ years with proper maintenance. Its 15mm wider profile versus Shark packs improves heat dissipation significantly.”
– Mikael Jansson, E-Mobility Engineer
- Can I Use This Battery with a 750W Motor?
- Yes, but ensure controller supports 48V input. The battery will deliver longer runtime than with 1000W systems (approx 35% increase). Reduce peak discharge rate via BMS settings to match motor specs.
- How to Check Remaining Battery Health?
- Use USB diagnostic tools ($15-30) connecting to BMS port. Key metrics:
– Total capacity vs original (below 70% = replace)
– Cell imbalance (above 0.1V = needs rebalancing)
– Cycle count (replace after 800 cycles) - Is Air Travel Permitted with This Battery?
- No. The 1000Wh capacity exceeds FAA’s 160Wh limit. Ground transport only. Some manufacturers offer 720Wh versions for air travel – verify specifications before purchase.
