Standards & Compliance
The ETENWOLF Vortex S7 battery pack was tested under the following international standard and regulatory framework:
- UN38.3 – United Nations Manual of Tests and Criteria, Part III, Section 38.3: The globally recognized standard governing the transport safety testing of lithium metal and lithium-ion batteries. Compliance is mandatory for air freight (IATA), sea freight (IMDG), and road transport (ADR).
- Revision 8 of the UN Manual of Tests and Criteria was specifically applied for this test, which is the most current revision at the time of testing.
The eight test procedures under UN38.3 Rev.8 are designed to evaluate battery behavior under simulated transport stress conditions including low-pressure altitude, extreme temperature cycling, mechanical vibration, mechanical shock, electrical short circuit, physical impact, overcharge scenarios, and forced discharge. A battery pack must pass all eight to be classified as compliant for transport.
The rated energy of 133.92 Wh places this battery pack in a category that requires documentation and declaration when transported by air under IATA Dangerous Goods Regulations (DGR), as it exceeds 100 Wh but is below 160 Wh per battery.
Validity & Certification Body

UN38.3 test summaries do not carry a fixed expiry date in the same manner as CE or FCC certificates. However, compliance documentation must remain current and consistent with the tested product configuration. Any design change to the battery cell chemistry, capacity, configuration, or protective circuitry would require re-testing. The document is valid as long as the battery pack model 3S4P-12400mAh remains unchanged from the tested specimen.
Frequently Asked Questions
- What is UN38.3 and why does the ETENWOLF Vortex S7 need it?
- UN38.3 is the international transport safety standard for lithium batteries, defined in the United Nations Manual of Tests and Criteria, Part III, Section 38.3. It requires batteries to pass eight safety tests simulating transport hazards. The ETENWOLF Vortex S7 contains a 133.92 Wh lithium-ion battery pack, and UN38.3 compliance is mandatory for its legal shipment by air, sea, and road internationally.
- What does report number WTH25D03074332B confirm?
- Report WTH25D03074332B, issued on 2025-04-09 by Waltek Testing Group Co., Ltd., confirms that the 3S4P-12400mAh rechargeable lithium-ion battery pack used in the ETENWOLF Vortex S7 passed all eight mandatory UN38.3 Revision 8 tests, including altitude simulation, thermal test, vibration, shock, external short circuit, impact/crush, overcharge, and forced discharge.
- Does the 133.92 Wh battery in the Vortex S7 have any air transport restrictions?
- Yes. Under IATA Dangerous Goods Regulations, lithium-ion batteries between 100 Wh and 160 Wh per battery (such as the 133.92 Wh pack in the ETENWOLF Vortex S7) may be transported as carry-on baggage with airline approval but are generally restricted in checked baggage. Shippers and carriers must verify current IATA DGR rules. UN38.3 compliance documentation like WTH25D03074332B is required.
- Who manufactured the battery pack and who tested it?
- The battery pack (model 3S4P-12400mAh) was manufactured by Guangdong Bestek Technology Co., Ltd., based in Heyuan City, Guangdong, China. Independent UN38.3 testing was carried out by Waltek Testing Group Co., Ltd., an accredited third-party laboratory located in Dongguan City, Guangdong, China.
