⚙️ Installation & Wiring Guide

  1. Verify Dimensions: Before hardwiring, test-fit the 260x110x68mm battery pack inside your intended enclosure (scooter deck, battery box, or frame bag).

  2. Controller Integration: Splice or solder the battery's primary discharge leads to your e-bike or scooter controller, matching the exact polarity (Red to Positive, Black to Negative). Ensure all connections are fully insulated with heat shrink.

  3. Secure the Pack: Ensure the battery is padded with vibration-dampening foam (EVA) inside its enclosure to prevent physical shock damage to the cells during off-road or high-speed riding.
