How Does the Hailong Battery Enhance Long-Range Cycling?
The Hailong 36V/48V 15Ah/20Ah Li-ion battery utilizes high-density 18650 cells, providing energy capacities of 540Wh (36V) or 960Wh (48V). This design supports ranges of 35–75 miles per charge, depending on motor wattage, terrain, and assist levels. Its optimized discharge curve ensures consistent voltage delivery, minimizing energy waste during acceleration or uphill rides.

What Safety Features Protect the Hailong Battery Pack?
Multi-layered safeguards include:
- Short-circuit protection: Cuts power within 0.1 seconds of abnormal current spikes
- Cell-level voltage monitoring: Balances charge across all 80–130 cells (depending on voltage/Ah)
- IP65 water resistance: Protects against rain and dust ingress
- Shock-absorbent casing: Withstands 1.2m drops onto concrete surfaces
The battery management system (BMS) employs redundant temperature sensors that sample cell heat every 200 milliseconds. During extreme conditions, it gradually reduces output instead of abrupt shutdowns – a critical feature for hill-climbing safety. The flame-retardant ABS casing contains ceramic thermal barriers between cell groups, delaying thermal runaway propagation by 18 minutes according to UL certification tests. Unique pressure relief vents automatically activate at 150kPa to prevent casing rupture during rare thermal events.

FAQs
- Q: Can I use a 48V battery on a 36V eBike?
- A: No—controller and motor windings may overheat. Always match battery voltage to your system’s rated specs.
- Q: How accurate is the built-in charge indicator?
- A: The 4-LED display has ±8% margin. For precise readings, pair with Bluetooth voltage meters (sold separately).
- Q: Does fast charging reduce lifespan?
- A: Yes—using 5A+ chargers decreases cycle count by 15–20%. Stick to 3A max for daily use.
“Modern eBikes demand batteries that balance energy density with durability. The Hailong series stands out by using automotive-grade nickel strips for inter-cell connections—a feature typically seen in premium EVs.”
