Test environment conditions were maintained at an ambient temperature of 20 °C – 25 °C and ambient humidity of 45% – 75%. Subcontracted testing was not applicable. The report was prepared by Jason Zhen (甄锦炎), reviewed by Jack Chen (陈咏松), and approved by Deval Qin (秦林伟).
Standards & Compliance
The HB1 battery pack was evaluated against the mandatory transport safety requirements for lithium cells and batteries under the following standard:
| Standard | Scope |
|---|---|
| ST/SG/AC.10/11/Rev.8, Section 38.3 | UN Manual of Tests and Criteria, Eighth Revision Edition Amendment — lithium battery transport safety tests |
UN38.3 defines a series of tests (T1 through T8) that lithium batteries must pass before they may be transported by air, sea, or land as dangerous goods. These tests include altitude simulation, thermal testing, vibration, shock, external short circuit, impact/crush, overcharge, and forced discharge. All applicable test items for the 1S1P-1100 cylindrical cell pack returned a Pass result. The overall conclusion of the report confirms that the submitted samples comply with the relevant requirements of the standard.
Validity & Certification Body
This test report was issued on 2025-10-22 and covers the battery model 1S1P-1100 (18350 cylindrical cell, 3.7 V / 1100 mAh) as used in the HB1. Report validity is subject to the issuing laboratory’s standard terms: the report may not be partially reproduced without prior written permission, and it is invalid if altered, unsigned by the approver, or lacking the official accreditation stamp of the institute.

Frequently Asked Questions
- What is UN38.3 and why is it required for the HB1 battery?
-
UN38.3 is the section of the United Nations Manual of Tests and Criteria that specifies the safety tests lithium cells and batteries must pass before international transport. Without a valid UN38.3 test report, carriers (airlines, shipping companies) are legally prohibited from accepting the battery for transport. The HB1 battery pack (1S1P-1100) passed all applicable UN38.3 tests as documented in report WTH25D09256005B, confirming it may be shipped safely.
- Which edition of the UN Manual was used for this report?
-
Testing was conducted against the Eighth Revision Edition Amendment of the UN Manual of Tests and Criteria (ST/SG/AC.10/11/Rev.8, Section 38.3), which is the current authoritative edition at the time of test.
- What are the key electrical specifications of the HB1 battery pack tested?
-
The battery pack tested is a cylindrical 18350 cell in a 1S1P configuration with a rated voltage of 3.7 V, rated capacity of 1100 mAh, and energy of 4.07 Wh. Maximum charge voltage is 5 V, maximum charge current is 1100 mA, and maximum discharge current is 11000 mA.
- Who conducted the UN38.3 testing and is Waltek an accredited laboratory?
-
Testing was performed by Waltek Testing Group Co., Ltd., based in Dongguan, Guangdong, China. Waltek is a nationally accredited third-party testing institute.
