Key Details
The UN38.3 standard requires lithium cells and batteries to pass a series of safety tests before they may be transported by air, sea, or land as dangerous goods. The table below lists every test procedure conducted on the ETENWOLF S1 battery pack (Model 2S1P-2600) and the corresponding result as recorded in report WTH25D12333150B.
| Test Procedure | Original (Chinese) | Result |
|---|---|---|
| T.1 — Altitude Simulation | 高度模拟 | Pass |
| T.2 — Thermal Test | 温度试验 | Pass |
| T.3 — Vibration | 振动 | Pass |
| T.4 — Shock | 冲击 | Pass |
| T.5 — External Short Circuit | 外部短路 | Pass |
| T.6 — Impact / Crush | 撞击 / 挤压 | Pass |

All 8 test procedures returned a Pass result. No failures, exceptions, or conditional passes were recorded. The battery pack is confirmed safe for transport under the provisions of the UN Recommendations on the Transport of Dangerous Goods — Manual of Tests and Criteria, Revision 8.
Standards & Compliance
The test summary is conducted in accordance with the internationally recognised UN38.3 standard, which is part of the UN Recommendations on the Transport of Dangerous Goods. Compliance with UN38.3 is a mandatory prerequisite for the air transport of lithium cells and batteries under IATA Dangerous Goods Regulations (DGR) and ICAO Technical Instructions, as well as for sea and road freight under IMDG and ADR/RID respectively.
- Standard Referenced: UN Recommendations on the Transport of Dangerous Goods — Manual of Tests and Criteria, Revision 8 (Rev.8)
- Applicable Transport Modes: Air (IATA DGR / ICAO TI), Sea (IMDG), Road/Rail (ADR/RID)
- Battery Chemistry: Lithium-ion (secondary lithium cell)
- Wh Rating: 19.24 Wh — falls below the 100 Wh per-cell and 300 Wh per-battery thresholds for Section II packaging provisions
- Test Scope: Full cell/battery-level testing; all 8 UN38.3 sub-tests conducted
- Test Criteria Edition: Rev.8 (the most current edition at the time of testing)

UN38.3 test summaries do not carry an explicit expiry date under the standard; however, they remain valid as long as the battery design, chemistry, cell configuration, and manufacturing process remain unchanged. Any material design change requires re-testing. The report number WTH25D12333150B serves as the unique traceability identifier for this test event.
Frequently Asked Questions
- What is UN38.3 and why does the ETENWOLF S1 battery pack need it?
-
UN38.3 is a set of transport safety tests defined in the UN Manual of Tests and Criteria for lithium cells and batteries. It is mandatory for all lithium batteries transported by air under IATA regulations and by sea under IMDG rules. The ETENWOLF S1 contains a 7.4 V / 19.24 Wh lithium-ion battery pack (model 2S1P-2600), so UN38.3 certification is required for its global shipping and distribution.
- Which specific tests did the ETENWOLF S1 battery pack undergo, and did it pass all of them?
-
The 2S1P-2600 battery pack was subjected to all 8 required UN38.3 test procedures: Altitude Simulation, Thermal Test, Vibration, Shock, External Short Circuit, Impact/Crush, Overcharge, and Forced Discharge. Every test returned a Pass result, as documented in report number WTH25D12333150B issued on 2026-01-13.
- What edition of the UN38.3 standard was used for this test?
-
The test was conducted in accordance with Revision 8 (Rev.8) of the UN Recommendations on the Transport of Dangerous Goods — Manual of Tests and Criteria. Revision 8 is the edition referenced in the official test summary document.
