Standards & Compliance
The S5C battery pack was evaluated against the following international transport safety standard:
| Standard | Full Title | Edition |
|---|---|---|
| UN38.3 | United Nations Recommendations on the Transport of Dangerous Goods — Manual of Tests and Criteria, Section 38.3: Lithium Metal and Lithium Ion Batteries | Eighth Revised Edition (ST/SG/AC.10/11/Rev.8) with Amendment |
UN38.3 testing encompasses a mandatory series of eight sequential abuse and stress tests designed to demonstrate that lithium battery cells and packs will not present a safety hazard during normal transport conditions. These tests verify resistance to altitude simulation, thermal extremes, vibration, mechanical shock, external short circuit, impact/crush, overcharge, and forced discharge. A battery pack must pass all applicable tests to be considered compliant and eligible for transport documentation.

Report Validity
UN38.3 test reports do not carry a fixed expiry date under the UN standard itself; however, the report remains valid for the specific product model, cell configuration, and electrical parameters tested. Any change to the cell chemistry, configuration (e.g., moving from 3S2P to a different topology), rated capacity, or protective circuit module (PCM/BMS) design may require re-testing. Carriers, freight forwarders, and customs authorities may impose their own validity windows — typically up to 3 years from the date of issue — so it is advisable to verify current acceptance policies with your logistics partner.

Frequently Asked Questions
- Q1: What is a UN38.3 test report and why does the S5C battery pack need one?
-
UN38.3 is the internationally recognised test standard for lithium batteries intended for transport. Regulators including IATA (air freight), IMDG (sea freight), and ADR (road transport) require that lithium-ion battery packs such as the one in the S5C pass UN38.3 testing before they can be legally shipped. Without a valid UN38.3 report, carriers are obligated to refuse the shipment.
- Q2: Which specific tests does UN38.3 Section 38.3 require?
-
The standard mandates up to eight tests: T.1 Altitude Simulation, T.2 Thermal Test, T.3 Vibration, T.4 Shock, T.5 External Short Circuit, T.6 Impact/Crush, T.7 Overcharge, and T.8 Forced Discharge. Tests marked N/A in the report are those that do not apply to the specific battery type or form factor. All applicable tests for the S5C 3S2P pack were passed successfully.
- Q3: Does the UN38.3 report cover the complete S5C product or only the battery?
-
Report WTH25D09236087B covers the battery pack only — specifically the 3S2P-5200mAh-S5C pack (11.1 V, 57.72 Wh, model ICR18650 cells). The complete S5C inflator as a finished goods assembly may require additional compliance documentation (e.g., CE, FCC, RoHS) for market access in different regions.
- Q4: How can I verify the authenticity of report WTH25D09236087B?
-
Waltek Testing Group is an accredited laboratory. You can verify the report by contacting Waltek directly at [email protected] or by phone at +86-769-2267 6998, quoting report number WTH25D09236087B. The report carries the signatures of the tester (Jason Zhen), reviewer (Jack Chen), and approving authority (Deval Qin) as part of its authentication chain.
