Standards & Compliance
The HB3 battery pack was evaluated against the following international standard for the safe transport of lithium batteries:
- UN Manual of Tests and Criteria, 8th Revision, Section 38.3 (ST/SG/AC.10/11/Rev.8) — This standard defines the test requirements that lithium cells and batteries must satisfy before they can be transported as dangerous goods. It includes tests covering altitude simulation, thermal cycling, vibration, shock, external short circuit, impact/crush, overcharge, and forced discharge.
The verdict notation used in the report is as follows:
- P (Pass) — The test object meets the requirement of the standard.
- F (Fail) — The test object does not meet the requirement of the standard.
- N/A — The test case does not apply to the test object.
All applicable test cases for the 2S2P-4000 battery pack received a Pass result, confirming compliance with UN38.3 transportation safety requirements.

UN38.3 test reports do not carry a fixed expiry date under the UN Recommendations themselves; however, the report remains valid as long as the product design, cell model, configuration, and materials remain unchanged. Any modification to the battery pack design or cell supplier would require re-testing.
Frequently Asked Questions
- What is UN38.3 and why does the HB3 battery pack need it?
- UN38.3 is the section of the United Nations Manual of Tests and Criteria that specifies safety tests for lithium cells and batteries intended for transport. Airlines, shipping carriers, and customs authorities worldwide require a valid UN38.3 test report before lithium battery products — including those used in the HB3 — can be legally transported as cargo or in consumer shipments.
- Which test specification version applies to report WTH25D09260771B?
- The report is based on the 8th Revision of the UN Manual of Tests and Criteria, Section 38.3 (ST/SG/AC.10/11/Rev.8), which is the current applicable edition at the time of testing.
- What are the key electrical specifications of the 2S2P-4000 battery pack used in the HB3?
- The battery pack is rated at 7.4 V, 4000 mAh, 29.6 Wh. It uses four INR18650-2000 cells in a 2-series 2-parallel configuration, with a maximum discharge current of 20000 mA. Full specifications are available on the HB3 product page.
