Key Details
The following table lists all eight UN38.3 transport safety tests conducted on the 2S1P-2000 lithium-ion battery pack, along with the result of each test. All tests were performed under the requirements of UN38.3 Rev.8.
| Test Item | Chinese Name | 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 |
All 8 required UN38.3 test items resulted in a Pass, confirming the battery pack meets the requirements for safe transport of lithium batteries by air, sea, and ground.
Standards & Compliance
The 2S1P-2000 battery pack was evaluated against the following internationally recognized standard:
- UN38.3 – United Nations Manual of Tests and Criteria, Revision 8: This standard defines the tests required for lithium metal and lithium-ion cells and batteries intended for transport. It is mandatory for air freight (IATA regulations) and applies to sea and road transport under IMDG and ADR frameworks respectively.
The eight test methods covered under UN38.3 Rev.8 applicable to this battery pack are:
- T.1 Altitude Simulation – Simulates low-pressure conditions at high altitude (11.58 kPa or less) for at least 6 hours.
- T.2 Thermal Test – Subjects cells or batteries to rapid, extreme temperature changes between +75°C and -40°C.
- T.3 Vibration – Tests resistance to vibration stress encountered during transport.
- T.4 Shock – Tests resistance to mechanical shock.
- T.5 External Short Circuit – Evaluates response when terminals are externally short-circuited.
- T.6 Impact / Crush – Applies a mechanical load to simulate physical impact or crush events during transport.
- T.7 Overcharge – Evaluates cell behavior when charged beyond its maximum rated voltage.
- T.8 Forced Discharge – Evaluates cell behavior when fully discharged by an external power source.
Validity & Certification Body
The UN38.3 test summary report bearing identification number WTH26D03058717B was issued on 2026-03-20 and signed by Deval Qin (秦林伟) in the capacity of Designated Reviewer.

UN38.3 test summaries do not carry a fixed expiry date in the way that some product certifications do. However, the report remains valid as long as the product design, chemistry, and manufacturing process remain unchanged. Any modification to the cell or battery configuration requires re-testing.
Frequently Asked Questions
- What is UN38.3 and why does the 2S1P-2000 battery pack need it?
-
UN38.3 is the international standard under the UN Manual of Tests and Criteria that defines safety tests for lithium cells and batteries during transport. The 2S1P-2000 battery pack requires this certification because carriers such as airlines (under IATA regulations) and shipping companies mandate UN38.3 compliance before accepting lithium batteries for transport.
- What does the unique report number WTH26D03058717B identify?
-
The report number WTH26D03058717B is the unique test report identification number assigned by Waltek Testing Group to this specific UN38.3 test summary for the 2S1P-2000 lithium-ion battery pack. It allows customs authorities, carriers, and buyers to trace the exact test record and verify its authenticity with the issuing laboratory.
- Which revision of the UN38.3 standard was used for this certification?
-
This certification was conducted in accordance with Revision 8 (Rev.8) of the UN Manual of Tests and Criteria. Rev.8 is the current edition and includes the latest requirements for altitude simulation, thermal testing, vibration, shock, short circuit, impact/crush, overcharge, and forced discharge tests.
- Does a UN38.3 pass guarantee the battery is safe for all types of shipment?
-
UN38.3 certification is a prerequisite for transporting lithium batteries, but carriers may impose additional requirements such as state-of-charge (SOC) limits, packaging standards (UN specification packagings), and quantity restrictions. The 2S1P-2000 battery pack having passed all 8 UN38.3 tests confirms its baseline transport safety, but shippers must also comply with IATA DGR, IMDG Code, or ADR regulations as applicable to the mode of transport.
