⚠ Wrong-fit hazards

Assuming any 'Hailong' fits. Hailong is a case STYLE, not one part. No.1, No.2 and the G-series have different mounts and connectors. Match your exact variant.
Mismatched connector. Same-size cases ship with 4-pin and 5-pin discharge plugs that are NOT interchangeable. Check yours.
Wrong voltage. Hailong cases exist in 36/48/52V — match your bike and controller.
High-current on an old No.1 tray. The original No.1 tray and its connector struggle with high-power 48/52V packs; the G-series is sturdier.
