⚠️ Compatibility & Mounting Fitment Notice

IMPORTANT CASE MODEL SELECTION GUIDELINES:

  • Supported Case Architectures: Designed to match the guide tracks and locking mechanisms of Hailong and Polly DP-series cases (DP-5, DP-5C, DP-6, DP-6C, DP-9, DP-9C) as well as G56 and G70 frame cases.

  • Terminal Block Verification: Check your battery case discharge port before ordering to select the correct matching pin configuration (4-pin, 5-pin, or blade style).

  • Frame Down-Tube Mounting: Features elongated mounting slots to align with standard water bottle cage bosses ($M5$ bolts) on aluminum and alloy bicycle frames.

🚀 Key High-Performance Features

  • Universal Polly & Hailong Fitment: Precision-molded rail channels allow smooth sliding engagement and secure key latching for DP-series cases.

  • High-Current Discharge Contacts: Reinforced terminal block design minimizes contact resistance, preventing thermal buildup during high-amp acceleration.

  • Vibration-Dampening Composite Shell: Constructed from high-impact ABS/polycarbonate polymer to absorb trail chatter and protect down-tube mounting bosses.

  • Flexible Controller Wiring: Pre-channeled discharge cavity allows clean wire routing directly to your motor controller without pinching cables.
