A total of 8 out of 8 test items passed with no failures recorded. The signed summary was authorized by Deval Qin (秦林伟), Designated Reviewer at Waltek Testing Group, on 2025-08-12.
Standards & Compliance
The testing procedure follows the requirements set out in the UN Recommendations on the Transport of Dangerous Goods — Manual of Tests and Criteria, Revision 8 (UN38.3). This standard is recognized globally across all major transport modes including air (IATA DGR), sea (IMDG Code), and road/rail (ADR/RID).
Key compliance points for the HB2 battery pack:
- Standard applied: UN38.3 Rev.8 — Transport of Dangerous Goods, Lithium Batteries
- Battery classification: Lithium-ion rechargeable battery pack, 7.4 V / 14.8 Wh — falls under the UN38.3 testing scope for cells and batteries shipped as cargo or contained in equipment
- Energy threshold: At 14.8 Wh the pack is below the 100 Wh threshold for individual lithium-ion cells in consumer equipment, making it eligible for standard transport conditions when test results are documented
- Test revision used: Revision 8, the current edition of the Manual at the time of report issuance

Frequently Asked Questions
- What is UN38.3 and why does the HB2 battery pack need it?
-
UN38.3 is the international standard that defines the safety tests lithium batteries must pass before they can be transported by air, sea, or land. The HB2 battery pack requires this certification so that it can legally and safely be shipped as cargo or contained in the finished product during global distribution.
- Which tests did the HB2 battery pack pass and what do they verify?
-
The 2S1P-2000 battery pack passed all eight UN38.3 tests: altitude simulation (low-pressure stability), thermal test (temperature cycling stability), vibration, mechanical shock, external short circuit, impact/crush, overcharge protection, and forced discharge protection. Together these tests confirm the battery will not leak, ignite, or explode under the stress conditions encountered during transport.
- What is report number WTH25D07201659B and how can it be verified?
-
WTH25D07201659B is the unique test report identification number assigned by Waltek Testing Group Co., Ltd. to the UN38.3 test summary for the HB2 battery pack (model 2S1P-2000). Carriers, freight forwarders, and customs authorities can use this number to request the full test report from Waltek directly at [email protected].
- Does the UN38.3 certificate expire?
-
UN38.3 test summaries do not have a mandatory expiry date. However, the results are only valid as long as the battery cell design, chemistry, capacity, and production process remain materially unchanged from what was tested. If any significant modification is made to the HB2 battery pack, re-testing is required before continued shipment.
