Key Details
UN38.3 mandates a series of eight tests (T.1 through T.8) designed to simulate the hazards that lithium batteries may encounter during transport. The HB2 battery pack model 2S1P-2000 was subjected to all applicable tests. Results are summarised below.
| Test No. | Test Name | Condition / Requirement | Result |
|---|---|---|---|
| T.1 | Altitude Simulation | Exposed to low pressure (11.6 kPa) at ambient temperature for ≥ 6 hours | PASS |
| T.2 | Thermal Test | Rapid temperature cycling between −40 °C and +75 °C; 10 cycles | PASS |
| T.3 | Vibration | Sinusoidal vibration per specified frequency and duration | PASS |
| T.4 | Shock | Half-sine shock pulses applied across three axes | PASS |
| T.5 | External Short Circuit | Short circuit at 55 °C ± 2 °C for ≥ 1 hour | PASS |
| T.6 | Impact / Crush | Applied force or crush as specified for the cell type | PASS |
| T.7 | Overcharge | Charged at twice the manufacturer’s maximum charge current | PASS |
| T.8 | Forced Discharge | Each cell force-discharged by a 12 V DC source | PASS |
Verdict key used in the original report: P (Pass) — test object meets the requirement; N/A — test case does not apply to the test object; F (Fail) — test object does not meet the requirement. All applicable tests for the 2S1P-2000 pack received a Pass verdict.
Standards & Compliance
The HB2 lithium-ion battery pack was tested in accordance with the following standard:
- UN ST/SG/AC.10/11/Rev.8, Section 38.3 — United Nations Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, Eighth Revised Edition, including the Amendment. This section specifically governs lithium metal and lithium-ion cells and batteries.
UN38.3 compliance is a mandatory prerequisite for the international transport of lithium batteries and battery-powered products by air (IATA DGR), sea (IMDG Code), and road/rail (ADR/RID). The report confirms that the 2S1P-2000 pack meets all transport safety requirements under this standard.
The report was prepared by Waltek Testing Group Co., Ltd., an internationally recognised third-party testing laboratory. The internal report template reference is WT-510-201-02-B.

UN38.3 test reports do not carry a fixed expiry date in the same manner as product certifications; however, the report remains valid as long as the battery design, cell model, and configuration remain unchanged. Any modification to the cell chemistry, capacity, configuration, or protection circuit board would require re-testing. The report covers only the specific model 2S1P-2000 using cells INR18650-2000 in a 2S1P configuration.
Frequently Asked Questions
- What is UN38.3 and why does the HB2 need it?
- UN38.3 is the section of the United Nations Manual of Tests and Criteria that defines the safety tests lithium batteries must pass before they can be legally transported internationally. The HB2 contains a built-in lithium-ion battery pack, so the UN38.3 certification is mandatory for air freight (IATA), ocean freight (IMDG), and road/rail (ADR/RID) shipment of the product.
- Which tests are included in UN38.3 and did the HB2 battery pack pass all of them?
- UN38.3 consists of 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. All applicable tests performed on the HB2 battery pack (model 2S1P-2000) received a Pass verdict as documented in report WTH25D07201659B.
- What are the key electrical specifications of the HB2 battery pack?
- The battery pack integrated in the HB2 is rated at 7.4 V / 2000 mAh / 14.8 Wh. It uses two INR18650-2000 cells in a 2S1P configuration, supports a maximum charge current of 2000 mA, and a maximum discharge current of 10,000 mA. The pack weighs approximately 100.1 g and measures 67.5 mm × 36.6 mm × 18.5 mm.
- Who conducted the UN38.3 testing for the HB2 and when was it completed?
- Testing was conducted by Waltek Testing Group Co., Ltd., a third-party testing laboratory based in Dongguan, Guangdong, China. Testing took place from 2025-07-30 to 2025-08-08, and the report was formally issued on 2025-08-12. The report was tested by Jason Zhen, reviewed by Jack Chen, and approved by Deval Qin.
