Key Details
The ETENWOLF L2 battery pack was tested across eight UN38.3 test procedures (T1 through T8). The sample matrix spanned multiple charge cycle states (1st cycle and 25th cycle) and charge level states (fully charged, 50% capacity, and fully discharged) to ensure comprehensive transport safety coverage. Test environment conditions were maintained at an ambient temperature of 20°C–25°C and relative humidity of 45%–75%. No subcontracted testing was involved.

Mass loss criteria applied: for samples with mass between 1 g and 75 g (which applies to this 56.1 g cell), the allowable mass loss limit is 0.2%. All samples remained within this threshold.
Standards & Compliance
The ETENWOLF L2 battery pack was evaluated against the following international transport safety standard:
| Standard | Title | Scope |
|---|---|---|
| UN ST/SG/AC.10/11/Rev.8, Section 38.3 | UN Recommendations on the Transport of Dangerous Goods — Manual of Tests and Criteria, Eighth Revised Edition (Amendment) | Lithium metal and lithium-ion cells and batteries intended for transport by air, sea, road, or rail |
UN38.3 is the globally recognized standard for qualifying lithium batteries for transport. Passing all eight test procedures (T1–T8) is mandatory for air freight compliance under IATA Dangerous Goods Regulations and ICAO Technical Instructions. The report number WTH25D05114738B serves as the traceable compliance reference for the 1S1P-2600 battery pack used in the ETENWOLF L2.
Test verdict codes used in this report:
- P (Pass) — Test object meets the requirement of the standard.
- F (Fail) — Test object does not meet the requirement.
- N/A — Test case does not apply to the test object.
Validity & Certification Body
This UN38.3 test report was issued on 2025-05-21 and covers the specific product model 1S1P-2600 as submitted by Guangdong Bestek Technology Co., Ltd. UN38.3 test reports do not carry a fixed expiry date under the UN model regulations; however, the report is considered valid as long as the product design, materials, and manufacturing processes remain unchanged from the tested samples.

Frequently Asked Questions
- What is UN38.3 and why does the ETENWOLF L2 battery pack need it?
-
UN38.3 is the international standard under the UN Recommendations on the Transport of Dangerous Goods that requires lithium batteries to pass a series of eight safety tests before they can be transported by air, sea, or land. The ETENWOLF L2 contains a 3.7V 2600mAh lithium-ion cell, which is classified as a dangerous good for transport purposes. Passing UN38.3 is mandatory for IATA and ICAO air freight compliance and is required by most international carriers and customs authorities.
- Which tests are included in UN38.3 and did the ETENWOLF L2 battery pass all of them?
-
UN38.3 requires eight tests: T1 Altitude Simulation, T2 Thermal Test, T3 Vibration, T4 Shock, T5 External Short Circuit, T6 Impact/Crush, T7 Overcharge, and T8 Forced Discharge. According to report WTH25D05114738B, the ETENWOLF L2 battery pack model 1S1P-2600 passed all applicable tests with no leakage, no venting, no disassembly, no rupture, and no fire observed in any test.
- What is the rated energy of the battery and does it affect shipping classification?
-
The 1S1P-2600 battery pack used in the ETENWOLF L2 has a rated energy of 9.62 Wh. Under IATA DGR, lithium-ion cells under 20 Wh and batteries under 100 Wh are classified as Section II items, which have less restrictive packaging and documentation requirements compared to Section I. The 9.62 Wh rating places this pack comfortably within Section II thresholds.
- How long is the UN38.3 test report valid, and when would a new test be required?
-
UN38.3 test reports do not have a mandated expiry date. Report WTH25D05114738B issued on 2025-05-21 remains valid as long as the battery design, cell chemistry, dimensions, mass, and electrical specifications of the 1S1P-2600 remain unchanged. Any modification to the cell model, configuration, protective circuit, or casing would typically require a new test to be performed to maintain compliance.
