Key Details
The following table lists all eight tests conducted under UN38.3 Rev.8, along with the result for the S5C battery pack. All required tests were completed and all results were Pass.
| Test Name | UN38.3 Test Reference | Result |
|---|---|---|
| Altitude Simulation (高度模拟) | T.1 | Pass |
| Thermal Test (温度试验) | T.2 | Pass |
| Vibration (振动) | T.3 | Pass |
| Shock (冲击) | T.4 | Pass |
| External Short Circuit (外部短路) | T.5 | Pass |
| Impact / Crush (撞击 / 挤压) | T.6 | Pass |
| Overcharge (过充电) | T.7 | Pass |
| Forced Discharge (强制放电) | T.8 | Pass |
A result of Pass for all eight tests confirms that the S5C lithium-ion battery pack meets the transport safety requirements for lithium batteries as defined under UN38.3, and is eligible for classification and shipment under applicable international dangerous goods regulations including IATA, IMDG, and ADR.
Standards & Compliance
The S5C battery pack was evaluated against the UN38.3 standard, which is the globally recognized test protocol for lithium metal and lithium-ion cells and batteries intended for transport. This standard is published by the United Nations Economic Commission for Europe (UNECE) as part of the Recommendations on the Transport of Dangerous Goods — Manual of Tests and Criteria.
- Standard Applied: UN38.3 — United Nations Manual of Tests and Criteria, Eighth Revised Edition (Rev.8)
- Battery Classification: Rechargeable Lithium-ion Battery Pack, 57.72Wh — classified under UN3481 (lithium-ion batteries contained in or packed with equipment) depending on shipment context
- Energy Threshold: At 57.72Wh, the S5C falls below the 100Wh per-cell and 300Wh per-battery thresholds, placing it in the standard consumer/portable power category
- Transport Modes Covered: Air (IATA DGR), Sea (IMDG Code), Road (ADR), and Rail (RID) — all reference UN38.3 compliance as a prerequisite
- Testing Body Accreditation: Waltek Testing Group Co., Ltd. is an accredited laboratory authorized to conduct and certify UN38.3 transport safety testing
Validity & Certification Body
The test summary report WTH25D09236087B was issued on 2025-09-16 and is valid for the product model S5C (3S2P-5200mAh-S5C) as long as the product design, chemistry, and configuration remain unchanged. Any modification to cell chemistry, capacity, configuration, or physical construction would require re-testing under UN38.3.

Frequently Asked Questions
- What is UN38.3 and why does the S5C battery need it?
-
UN38.3 is the international transport safety standard for lithium batteries published by the United Nations. It requires batteries to pass eight tests covering altitude simulation, thermal stress, vibration, shock, short circuit, impact or crush, overcharge, and forced discharge before they can be legally shipped by air, sea, or road. The S5C battery obtained this certification to ensure safe and compliant global shipping.
- Which revision of UN38.3 was used for the S5C test report?
-
The S5C was tested against the Eighth Revised Edition (Rev.8) of the UN Manual of Tests and Criteria, as stated in report WTH25D09236087B issued on 2025-09-16. Rev.8 is the current edition and includes updated requirements for lithium battery transport testing.
- Did the S5C battery pass all required UN38.3 tests?
-
Yes. All eight mandatory tests — altitude simulation, thermal test, vibration, shock, external short circuit, impact/crush, overcharge, and forced discharge — returned a result of Pass. The complete results are recorded in report WTH25D09236087B by Waltek Testing Group Co., Ltd.
- Is the UN38.3 test summary sufficient to ship the S5C battery internationally?
-
The UN38.3 test summary is a key required document for shipping lithium-ion batteries internationally. For air freight, carriers following IATA DGR also require a Material Safety Data Sheet (MSDS/SDS) and, depending on the shipper, a state-of-charge declaration. The S5C at 57.72Wh falls within the standard limits for lithium-ion batteries, but always confirm current carrier and customs requirements before shipment.
