Subcontracted testing: Not applicable. The overall test conclusion confirms that all submitted samples comply with the relevant requirements of the standard.
Standards & Compliance
The ETENWOLF V3 battery pack was tested against the following international standard for the safe transport of lithium batteries:
| Standard | Full Title | Edition |
|---|---|---|
| UN38.3 | UN Recommendations on the Transport of Dangerous Goods — Manual of Tests and Criteria, Section 38.3 | Eighth Revision (ST/SG/AC.10/11/Rev.8) with Amendment |
UN38.3 is a mandatory international standard that all lithium battery cells and packs must pass before they may be transported by air, sea, or road. The test series covers altitude simulation (T1), thermal cycling (T2), vibration (T3), shock (T4), external short circuit (T5), impact/crush (T6), overcharge (T7), and forced discharge (T8). The 3S1P-2600 battery pack passed all applicable items under the Eighth Revision of the Manual of Tests and Criteria, demonstrating that it poses no unacceptable hazard during normal transport conditions.

Frequently Asked Questions
- What is UN38.3 and why does the ETENWOLF V3 battery pack need it?
-
UN38.3 is the internationally recognised standard published by the United Nations for the safe transport of lithium batteries. It requires cells and battery packs to pass eight distinct tests — covering altitude, temperature extremes, vibration, mechanical shock, short circuit, crush/impact, overcharge, and forced discharge — before they may be shipped by air, sea, or ground freight. The ETENWOLF V3 battery pack holds this certification (report number WTH25D05129151B) to ensure it can be legally and safely transported worldwide.
- What are the key electrical specifications of the V3 battery pack?
-
The 3S1P-2600 battery pack inside the ETENWOLF V3 operates at a nominal voltage of 11.1 V with a rated capacity of 2600 mAh (28.86 Wh). It accepts charging via Type-C at 5V/1.5A or 9V/1.5A, and can discharge at up to 15 A through the pump terminals (M+/M−), making it suitable for high-current inflation motor applications.
- Which laboratory issued the UN38.3 test report and is it accredited?
-
The report was issued by Waltek Testing Group Co., Ltd. (深圳沃特检验集团股份有限公司), an established third-party testing organisation headquartered in Dongguan, Guangdong, China. Waltek is widely recognised for providing accredited battery safety testing services. The report reference is WTH25D05129151B, issued on 2025-06-26.
- Does passing UN38.3 mean the battery pack is safe for air transport?
-
UN38.3 compliance is a necessary prerequisite for air transport of lithium batteries under IATA Dangerous Goods Regulations. A passing result — as achieved by the ETENWOLF V3 battery pack — confirms the cells meet the required safety thresholds. Shippers must still comply with applicable quantity limits, packaging requirements, and airline-specific policies for lithium battery shipments.
Related Documents
The following certification and compliance documents are typically required alongside UN38.3 for a lithium-battery-powered portable inflator such as the ETENWOLF V3:
- CE Declaration of Conformity — Required for sale within the European Economic Area; covers applicable EU directives including the Low Voltage Directive and EMC Directive.
- FCC ID Certificate — Required for sale in the United States; verifies radio frequency and electromagnetic compatibility compliance.
- RoHS Compliance Report — Confirms restriction of hazardous substances (lead, mercury, cadmium, etc.) in electrical and electronic equipment sold in the EU and other markets.
- REACH SVHC Declaration — Documents that no Substances of Very High Concern exceed threshold levels in the product, as required under EU REACH regulations.
- IEC 62133 Battery Safety Test Report — Covers secondary lithium cell and battery safety for portable applications, complementing the transport-focused UN38.3 standard.
- KC Certification — Required for products sold in South Korea; covers electrical safety and EMC for lithium battery products.
