Standards & Compliance
The testing was carried out against the transport safety requirements for lithium batteries under the following standard framework:
- UN38.3 — United Nations Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, Revision 8. This standard governs the safe transport of lithium metal and lithium-ion cells and batteries by all modes of transport (air, sea, road, rail).
- The battery pack with a rated energy of 14.8 Wh falls below the 100 Wh threshold applicable to lithium-ion cells and battery packs under IATA Dangerous Goods Regulations and ICAO Technical Instructions, confirming its eligibility for air transport under standard provisions.
- Compliance with UN38.3 is also a prerequisite for CE, FCC, KC, and other regional market access certifications that include battery safety assessments.
Test methods applied correspond to Section 38.3 of the UN Manual, sub-tests T.1 through T.8, as defined in Revision 8 of the standard.

Manufacturers and importers are advised to retain this document for supply chain due diligence and customs clearance purposes.
Frequently Asked Questions
- What is UN38.3 and why does the ETENWOLF C2 battery need it?
- UN38.3 is the international standard that lithium-ion batteries must pass before they can be legally transported by air, sea, or road. For the ETENWOLF C2, having this certification means the 7.4V 2000mAh battery pack has been independently verified to be safe under conditions such as low pressure, extreme temperatures, vibration, shock, short circuit, overcharge, and forced discharge.
- Which revision of UN38.3 was used for this test?
- The tests were conducted in accordance with Revision 8 of the UN Manual of Tests and Criteria, which is the most current revision at the time of report issuance on 2025-09-22. Revision 8 introduced updated requirements for larger lithium batteries and tightened altitude simulation conditions.
- Did the C2 battery pack pass all UN38.3 tests?
- Yes. All eight mandatory tests — altitude simulation, thermal test, vibration, shock, external short circuit, impact/crush, overcharge, and forced discharge — returned a Pass result. The unique report number for this certification is WTH25D09239218B, issued by Waltek Testing Group on 2025-09-22.
- Where can I obtain a copy of the UN38.3 test report for the ETENWOLF C2?
- The official test summary document (report no. WTH25D09239218B) is issued by Waltek Testing Group Co., Ltd. For supply chain, customs, or compliance purposes, contact ETENWOLF directly through the ETENWOLF product page or reach Waltek at [email protected].
