Key Details
The following table lists every UN38.3 test conducted on the ETENWOLF L2 battery pack and the corresponding result. All eight mandatory tests were performed against UN38.3 Revision 8 requirements.
| Test | UN38.3 Section | Result |
|---|---|---|
| Altitude Simulation | T.1 | Pass |
| Thermal Test | T.2 | Pass |
| Vibration | T.3 | Pass |
| Shock | T.4 | Pass |
| External Short Circuit | T.5 | Pass |
| Impact / Crush | T.6 / T.7 | Pass |
| Overcharge | T.8 | Pass |
| Forced Discharge | T.9 | Pass |
A pass result on all tests confirms that the battery pack does not exhibit leakage, venting, disassembly, rupture, fire, or explosion under the simulated transport and abuse conditions defined by UN38.3 Rev.8.
Standards & Compliance
The ETENWOLF L2 battery pack was evaluated against the following standard and test criteria.
- Primary Standard: United Nations Recommendations on the Transport of Dangerous Goods — Manual of Tests and Criteria, Part III, Section 38.3 (UN38.3), Revision 8
- Test Scope: Eight tests covering simulated air transport (low pressure), thermal extremes (–40 °C to +75 °C), mechanical stress (vibration and shock), electrical abuse (short circuit, overcharge, forced discharge), and mechanical abuse (impact/crush)
- Cell Chemistry: Lithium-ion — subject to IATA Dangerous Goods Regulations (DGR), IMDG Code, and ADR road transport rules for lithium batteries
- Energy Threshold: At 9.62 Wh the cell falls below the 20 Wh per-cell threshold, qualifying it as a small lithium-ion cell under transport regulations

Frequently Asked Questions
- What is UN38.3 and why does the ETENWOLF L2 need it?
- UN38.3 is the international transport safety standard for lithium batteries published by the United Nations. It proves that a battery will not catch fire, explode, or leak under the conditions experienced during air, sea, or road transport. The ETENWOLF L2 contains a lithium-ion battery pack, so UN38.3 certification is mandatory for legal shipment worldwide.
- What does a Pass result on all eight tests mean for consumers?
- It means the 1S1P-2600 battery pack inside the ETENWOLF L2 has been independently verified to withstand low-pressure altitude conditions, extreme temperatures, vibration, shock, short circuits, overcharge, forced discharge, and mechanical impact without any safety incident. Consumers and logistics partners can be confident the product meets international transport safety requirements.
- Which revision of UN38.3 was used for this test?
- The tests were conducted in accordance with UN38.3 Revision 8, the most current edition of the standard at the time of testing. Report number WTH25D05114738B was issued on 2025-05-21.
- Who conducted the UN38.3 testing for the ETENWOLF L2 battery pack?
- Testing was performed by Waltek Testing Group Co., Ltd., an accredited third-party laboratory located in Dongguan, Guangdong, China. The report was reviewed and signed by Designated Reviewer Qin Linwei (Deval Qin) on 2025-05-21.
