Standards & Compliance
The Helios J1 was tested against the requirements set out in the UN Manual of Tests and Criteria, Revision 8, specifically Section 38.3, which applies to lithium metal and lithium-ion cells and batteries intended for transport. UN38.3 is a globally recognized standard required by IATA, ICAO, IMDG, and ADR regulations for the air, sea, and road transport of lithium battery products. The test covers a comprehensive battery of assessments designed to simulate transport stresses including low-pressure environments, extreme temperatures, mechanical vibration and shock, electrical abuse scenarios, and physical deformation. Passing all eight test items demonstrates that the Helios J1 battery pack does not pose a safety hazard during normal transport conditions.
Validity & Certification Body
The test report WTH25D06164718B was issued on 2025-07-04 and is valid in accordance with the standard practice for UN38.3 test summaries, which remain applicable as long as the product design and cell specifications remain unchanged. Any modification to the battery cell type, configuration, or rating would require re-testing.
