hailong battery 48v 17.5ah 48V 13.6Ah eBike Battery with HAILONG case

48V Hailong Downtube E-Bike Battery

The "Hailong" battery is a benchmark in the e-bike industry, widely recognized for its robust, durable case and versatile compatibility. Designed to mount cleanly on the bike's downtube, it offers a secure, balanced, and integrated power solution for a wide range of electric bicycles and conversion kits. This 48V version is a perfect match for riders seeking a significant boost in performance and range.

Key Specifications:

• Voltage: 48V Nominal Voltage. This is a powerful and efficient choice for motors from 500W up to 1500W. A 48V system provides noticeable gains in acceleration, torque, and top speed compared to standard 36V batteries.

• Capacity Options:

  • 13.6Ah: This capacity offers a great balance of size, weight, and range. It is suitable for daily commutes and recreational rides, providing ample power without adding excessive bulk to the bike.

  • 17.5Ah: This high-capacity option is for riders who demand maximum range. It provides a massive energy reserve for long-distance touring, extended commutes, or all-day trail riding, significantly reducing "range anxiety."

• Energy Rating (Wh): The Watt-hour rating directly indicates the battery's total energy storage:

  • 48V 13.6Ah: 652.8Wh ($48V\times 13.6Ah=652.8Wh$).

  • 48V 17.5Ah: 840Wh ($48V\times 17.5Ah=840Wh$).

• Battery Cells: The best Hailong batteries are built with premium, high-density lithium-ion cells from industry-leading manufacturers like Samsung, LG, or Panasonic. The cell configuration is typically a 13S4P (13.6Ah) or 13S5P (17.5Ah) arrangement, ensuring a high-quality, long-lasting pack.

• Motor Compatibility: A key feature is the high-amperage Battery Management System (BMS) that can handle continuous discharge currents of 30A or more. This makes it compatible with powerful motors ranging from 250W to 1500W, allowing for a wide range of applications from casual cruising to high-performance riding.

Features and Design:

• Durable Hailong Case: The robust and well-engineered plastic case protects the battery's internal cells from physical impacts, vibrations, and the elements. The case design is a standard in the industry, making it easy to find compatible mounting hardware and replacement parts.

• Secure & Removable: The battery securely locks onto its mounting base with a key, preventing theft. It can be easily slid on or off for convenient off-bike charging or secure storage indoors.

• Integrated USB Port: Many modern Hailong batteries come equipped with a 5V USB output port, which is a highly convenient feature for charging your smartphone, GPS, or other USB-powered devices while on the go.

• Battery Management System (BMS): A sophisticated, integrated BMS provides crucial protection against a variety of issues, including:

  • Over-charging and over-discharging

  • Over-current and short circuits

  • Overheating This ensures the battery's safety and extends its cycle life to over 800-1000 charges.

• LED Power Indicator: A clear, multi-level LED indicator on the side of the battery provides a quick visual check of the remaining charge level at a glance.

• Wide Compatibility: The Hailong battery is a universal solution for many e-bike brands and DIY conversion kits. It's a popular choice for bikes using Bafang, Tongsheng, and other common hub and mid-drive motors
