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.

🚀 Key High-Performance Features

Advanced Integrated 30A BMS: Safeguards battery cells against overcharge, over-discharge, overcurrent, thermal spikes, and short circuits.
Long-Life Grade-A Lithium Chemistry: Rated for 1500+ full charge/discharge cycles, providing years of high-capacity performance.
Ergonomic Hailong Down-Tube Case: High-impact ABS shell mounts directly to standard water bottle cage bosses for low center-of-gravity handling.
Integrated Key Lock & Power Switch: Keyed mechanical lock secures the battery to the mounting cradle to prevent theft; power switch conserves charge while parked.
LED Power Indicator: Check remaining battery charge at a glance.
