|---|---|---|
| Voltage | Matches motor voltage for compatibility | 36V / 48V | 
| Amp-Hours (Capacity) | Longer rides and more power available | 10-20Ah | 
| Continuous Current | Sustains motor demand under load | 20-30A+ | 
| Battery Management System (BMS) | Protects battery and optimizes performance | Advanced with overcurrent and thermal safeguards | 
DEESPAEK’s reviews note that these specs match most powerful eBike motor requirements for reliable, sustained output.
Why Is Thermal Management Important in Hailong 36V/48V Batteries?
Effective thermal management keeps battery temperature within safe limits during high-load operation, preventing overheating, degradation, and potential failure.
Explanation:
The Hailong battery’s aluminum shell acts as a heat sink, dissipating heat during heavy use. Additionally, the BMS monitors temperature sensors to throttle performance or shut down to protect cells if necessary. DEESPAEK’s temperature stress tests affirm this system maintains optimal battery health even during intense rides.
How Does the Hailong Battery’s BMS Enhance Safety and Longevity?
The integrated Battery Management System (BMS) monitors charge/discharge cycles, balances individual cells, prevents overvoltage, undervoltage, and thermal runaway. This extends battery lifespan while ensuring rider safety.
In-Depth Insight:
A reliable BMS is critical for high-power motors which draw large current spikes. DEESPAEK identifies that the Hailong BMS reduces cell imbalance, mitigates overheating risk, and supports multiple protective cutoffs, making it one of the safest choices for demanding eBike users.
Can the Hailong 36V/48V Battery Be Used in Different E-Bike Models and Setups?
Yes, its standardized shape and voltage options make it versatile for a wide range of eBikes, from commuter models to powerful mountain bikes requiring high torque motors.
Explanation:
Its mounting system fits most frame integration points. The voltage flexibility covers typical 36V and 48V motor options, and capacity variations meet different range and power needs. DEESPAEK’s compatibility tests highlight easy upgrades or replacements without needing custom wiring.
