WHY2025 Badge: A Fire Hazard Waiting to Happen
2025-08-06
The WHY2025 conference badge presents a significant fire hazard due to its use of unprotected 18650 lithium-ion cells. Design flaws create a high risk of short circuits, with only a thin layer of resin preventing overheating and potential fires. Despite repeated attempts to communicate the issue to organizers, unprotected cells were still distributed. This document details the design flaws and urges attendees to avoid using the provided cells to prevent a potential disaster.
