⚠️ Terminal Pin & Case Compatibility Notice

IMPORTANT TERMINAL SELECTION & CASE GUIDELINES:

  • Supported Case Architectures: Fits ChamRider, Hailong, and Polly DP-series cases (G56, G70, DP-5/5C, DP-6/6C, DP-9/9C).

  • Terminal Block Configuration (4-Pin / 5-Pin Options): Inspect your battery's bottom discharge port before ordering:

    • 4-Pin Blade Contact: Matches 4-pin discharge sockets (Common on 4C/5C cases).

    • 5-Pin Blade Contact: Matches 5-pin discharge sockets (Common on G56/G70 cases).

  • Frame Attachment: Slots align directly with standard $M5$ water bottle cage bosses on aluminum bicycle down-tubes.

🚀 Key High-Performance Features

  • Precision Molded Guide Rails: Precision-engineered tracks ensure smooth slide-in battery docking and solid key lock engagement.

  • High-Current Brass Contact Block: Solid brass terminal contacts minimize resistance, preventing thermal buildup during hard acceleration.

  • Vibration-Dampening Shell Construction: Reinforced ABS/polycarbonate housing absorbs trail chatter and protects down-tube mounting bosses.

  • Integrated Wire Channel & Discharge Leads: Built-in discharge cable cavity allows clean, pinch-free wire routing directly to your motor controller.
