The Hailong Lithium Battery Pack is one of the most popular form factors for DIY e-bike conversions and replacement batteries. The "Hailong" name (often called a "shark" or "rocket" pack) refers to the distinct, aerodynamic plastic casing designed to mount securely onto the water bottle bosses of a standard bicycle frame.Here is a breakdown of the technical specifications and features associated with this type of battery pack.
-
Cell Type (LG5000): This indicates the use of high-capacity lithium-ion cells (likely 21700-style 5000mAh cells). These cells are preferred for their high energy density, allowing for long range in a compact size.
-
BMS (Battery Management System) - 50A: The 50A BMS is the "brain" of the battery. It regulates charging/discharging and provides safety protections (overcharge, over-discharge, over-temperature, and short-circuit protection). A 50A rating means it can comfortably handle high-power motors (typically up to 1500W–2000W) without triggering a shutdown.
-
XT60 Connector: The XT60 is the industry-standard connector for this type of project. It is chosen for its robust, vibration-resistant connection, high current-carrying capacity, and ease of use when connecting to an e-bike controller.
-
Housing: The ABS plastic case is designed to be lightweight, weather-resistant, and impact-resistant, protecting the internal cell array from road debris and light moisture (though not fully submersible)
