Key Details
The following table lists all eight UN38.3 tests conducted on the ETENWOLF C2PRO battery pack, along with the recorded result for each test. All tests were completed under the requirements of UN38.3 Rev. 8.
| Test Item | Original (Chinese) | Result |
|---|---|---|
| Altitude Simulation | 高度模拟 | Pass |
| Thermal Test | 温度试验 | Pass |
| Vibration | 振动 | Pass |
| Shock | 冲击 | Pass |
| External Short Circuit | 外部短路 | Pass |
| Impact / Crush | 撞击 / 挤压 | Pass |
| Overcharge | 过充电 | Pass |
| Forced Discharge | 强制放电 | Pass |
The battery pack achieved a Pass result on all 8 required test items, confirming it meets the safety requirements for classification and transport as a lithium-ion battery under UN regulations.
Standards & Compliance
The test was conducted in full accordance with the following standard and regulatory framework:
- UN38.3 – 8th Revised Edition (Rev. 8): United Nations Manual of Tests and Criteria, Part III, Section 38.3. This is the internationally recognised standard governing the testing and safe transport of lithium metal and lithium-ion cells and batteries via all transport modes.
- Altitude Simulation (T.1): Simulates low-pressure conditions at high altitude during air transport.
- Thermal Test (T.2): Evaluates battery performance and integrity under rapid, extreme temperature cycling.
- Vibration (T.3): Assesses structural integrity under vibration loads typical of transport.
- Shock (T.4): Tests resistance to mechanical shock during handling and transit.
- External Short Circuit (T.5): Verifies safe response to unintended external short-circuit conditions.
- Impact / Crush (T.6 / T.7): Evaluates cell and pack response to physical deformation forces.
- Overcharge (T.8): Confirms protection against overcharging beyond rated limits.
- Forced Discharge (T.9): Tests safe behaviour when a cell is fully discharged under forced conditions.
Passing all nine test criteria under UN38.3 Rev. 8 is mandatory for lithium-ion batteries to be legally transported internationally, including by air (IATA DGR) and sea (IMDG Code).

Frequently Asked Questions
- What is UN38.3 and why does the ETENWOLF C2PRO need it?
-
UN38.3 is the United Nations standard that all lithium-ion batteries must pass before they can be transported by air, sea, or road internationally. The ETENWOLF C2PRO contains a 7.4V 2600mAh lithium-ion battery pack, which means it is subject to these transport regulations. Having a valid UN38.3 test summary (Report No. WTH25D11289146B) confirms the battery is safe for shipping and complies with IATA and IMDG requirements.
- Which revision of UN38.3 was used for this test?
-
The test was conducted under Revision 8 (Rev. 8) of the UN Manual of Tests and Criteria, which is the most current edition at the time of testing. Rev. 8 includes updated requirements for lithium-ion battery packs and is recognised globally by transport authorities.
- Did the C2PRO battery pack pass all UN38.3 tests?
-
Yes. The ETENWOLF C2PRO battery pack (Model 2S1P-2600) passed all eight required test items, including altitude simulation, thermal, vibration, shock, external short circuit, impact/crush, overcharge, and forced discharge. There were no failures or conditional results.
- Who manufactured the battery pack and who tested it?
-
The battery pack was manufactured by Guangdong Bestek Technology Co., Ltd., located in Heyuan City, Guangdong, China. Independent third-party testing was performed by Waltek Testing Group Co., Ltd. in Dongguan, Guangdong, China, a nationally accredited testing laboratory.
