⚠️ Key Performance & Safety Guidelines
IMPORTANT VEHICLE & BATTERY SPECIFICATIONS:
Optimized for Bafang Mid-Drive Motors: Internal high-current BMS is built to handle the heavy peak amp draws of Bafang BBS02 (750W), BBS03, and high-output BBSHD (1000W+) drive systems.
Standard Hailong Down-Tube Form Factor: Compact 360×90×110 mm outer dimensions mount directly to standard water bottle cage braze-ons on most bicycle frames.
High-Output 52V Architecture Option: Selecting the 52V configuration delivers reduced voltage drop under load, increased top-end motor RPM, and cooler motor operating temperatures.
Integrated Safety BMS: Multi-stage Battery Management System guards against over-charging, over-discharging, short circuits, and thermal runaway.
