Standards & Compliance
This test summary was prepared in full conformance with the transport safety requirements for lithium cells and batteries established by the United Nations Manual of Tests and Criteria, 8th Revised Edition (Rev. 8). UN38.3 compliance is a mandatory prerequisite for the international transport of lithium-ion batteries by any mode, including air freight under IATA Dangerous Goods Regulations and sea freight under IMDG Code requirements.
- Standard Applied: UN Manual of Tests and Criteria — Section 38.3, Rev. 8
- Battery Chemistry: Lithium-ion (Li-ion), 1S1P cell configuration
- Energy Threshold: 5.7 Wh (below the 20 Wh per cell threshold for Section II shipping)
- Test Methodology: Independent third-party laboratory testing at Waltek Testing Group facilities, Dongguan, Guangdong, China
- Scope of Compliance: Covers altitude simulation, thermal cycling, mechanical vibration and shock, electrical abuse (short circuit, overcharge, forced discharge), and physical integrity (impact/crush)
The 5.7 Wh energy rating of this battery pack keeps it well within the limits applicable to consumer-grade lithium-ion cells transported under standard dangerous goods exemptions, supporting straightforward logistics for the ETENWOLF L1 globally.
Validity & Certification Body
The test report bearing number WTH25D05118921B was issued on 2025-05-23 and remains valid subject to no changes to the battery cell design, chemistry, configuration, or manufacturing process. Any material modification to the product requires re-testing under UN38.3.

Frequently Asked Questions
- What is UN38.3 and why does the ETENWOLF L1 battery need it?
-
UN38.3 is the section of the United Nations Manual of Tests and Criteria that defines the safety tests lithium cells and batteries must pass before they can be legally transported internationally. The ETENWOLF L1 battery pack requires UN38.3 certification so that the finished product can be shipped by air, sea, or road without restriction under IATA, IMDG, and ADR dangerous goods regulations.
- Which revision of UN38.3 was used for this test, and does it matter?
-
This test was conducted under Rev. 8 of the UN Manual of Tests and Criteria, which is the most current edition. Using the latest revision ensures the certification is accepted by carriers and customs authorities worldwide and will not be rejected due to an outdated test standard.
- What does the 1S1P configuration mean for the L1 battery pack?
-
1S1P means one cell in series and one cell in parallel — in other words, the pack consists of a single lithium-ion cell. The cell operates at 3.8 V with a capacity of 1500 mAh, giving a total energy of 5.7 Wh. This compact, single-cell design contributes to the lightweight and portable nature of the ETENWOLF L1 inflation tool.
- Is the UN38.3 certificate permanent, or does it expire?
-
The UN38.3 test report (No. WTH25D05118921B) does not carry a fixed expiry date in the same way as some other certifications; however, it becomes invalid if the battery design, cell chemistry, electrical ratings, or manufacturing process are changed. Any such modification requires a new round of UN38.3 testing before the product can continue to be shipped internationally.
