36V 48V 52V Long Range E-Bike Li-ion Replacement
High-Output Hailong Li-Ion E-Bike Battery Pack (36V / 48V / 52V Options)
Upgrade your range and acceleration with the TINSAAS Hailong Lithium-Ion E-Bike Battery Pack. Engineered for high-demand mid-drive and hub motor setups (including Bafang, Tongsheng, and Voilamart conversion kits), this battery features a built-in 30A Continuous Battery Management System (BMS) to deliver stable output for motor systems ranging from 250W up to 2000W. Encased in a rugged, weather-resistant Hailong down-tube housing with an integrated key-lock mechanism, this pack provides maximum thermal efficiency, impact absorption, and long-range energy density.
⚠️ Motor Matching & Voltage Compatibility Guidelines
IMPORTANT MOTOR & VOLTAGE SELECTION GUIDE:
36V Configurations (13Ah – 24.5Ah): Ideal for standard 250W, 350W, and 500W street-legal commuting motors.
48V Configurations (13Ah – 24.5Ah): Optimized for high-torque 500W, 750W, and 1000W hub or mid-drive systems (e.g., Bafang BBS02, HD, or Fat Tire e-bikes).
52V Configurations (13Ah – 24.5Ah): Delivers maximum top-end speed, reduced voltage sag, and peak thermal efficiency for 750W, 1000W, 1500W, and 2000W performance builds.
Frame Clearance Check: The standard Hailong case length measures 367mm (14.45 in). Ensure your frame's inner triangle allows at least 390mm to clear the rail sliding mechanism during installation/removal.
