| T.8 | Forced Discharge | 38.3.4.8 | ✔ Pass |
Overall Outcome: All 8 tests passed. The battery pack showed no leakage, venting, disassembly, rupture, fire, or explosion under any of the prescribed test conditions.
Standards & Compliance
The test campaign was conducted in full accordance with the following standard and reference edition:
- UN Manual of Tests and Criteria, Part III, Sub-section 38.3 — 8th Revised Edition (Rev.8) — The globally recognized standard governing the transport safety testing requirements for lithium metal and lithium-ion cells and batteries.
Each of the eight test procedures evaluates a specific hazard scenario relevant to the transportation of lithium batteries:
- Altitude Simulation: Verifies integrity at low-pressure conditions simulating air cargo holds (11.6 kPa, 6 hours minimum).
- Thermal Test: Assesses performance under rapid temperature cycling between −40 °C and +75 °C.
- Vibration: Confirms structural integrity under sinusoidal vibration profiles representative of transport conditions.
- Shock: Validates resistance to half-sine mechanical shock pulses.
- External Short Circuit: Tests the battery management system (BMS) response and cell behavior under direct external short-circuit at elevated temperature.
- Impact / Crush: Ensures no thermal runaway or fire when a cell is mechanically deformed.
- Overcharge: Confirms safe behavior when charged beyond the maximum specified voltage.
- Forced Discharge: Validates safety during reversal of polarity caused by forced over-discharge.
The ETENWOLF V3 battery pack passed all eight tests with no failures, confirming full compliance with UN38.3 Rev.8 transport safety requirements.
Validity & Certification Body
The test report WTH25D05129151B was issued on 2025-06-26. UN38.3 test summaries do not carry a fixed expiry date in themselves; however, the report remains valid for transport documentation purposes as long as the battery design, chemistry, and manufacturing process remain unchanged from those tested. Any material change to the battery design requires re-testing.

Frequently Asked Questions
- What does UN38.3 certification mean for the ETENWOLF V3 battery pack?
-
UN38.3 is the mandatory international safety standard — defined in the UN Manual of Tests and Criteria — that all lithium-ion batteries must pass before they can be legally shipped by air, sea, or road. For the ETENWOLF V3 battery pack, passing all eight UN38.3 Rev.8 tests confirms that the 3S1P-2600 cell (11.1 V / 2600 mAh / 28.86 Wh) is safe for international transport and meets the requirements set by IATA, IMDG, and ADR dangerous-goods regulations.
- Which edition of UN38.3 was used for this test, and why does the edition matter?
-
This battery pack was tested to the 8th Revised Edition (Rev.8) of the UN Manual of Tests and Criteria — the most current edition at the time of testing. The edition matters because each revision may introduce updated test parameters, acceptance criteria, or entirely new test requirements. Using Rev.8 ensures the V3 battery pack meets the latest transport-safety expectations from global regulatory bodies.
- What happens if the battery pack fails any one of the UN38.3 tests?
-
A failure in any single UN38.3 test — such as a fire, explosion, rupture, or leakage event — would disqualify the battery from transport as currently designed. The manufacturer would need to identify the root cause, modify the design or BMS, and resubmit the product for a full or partial re-test. In this case, the ETENWOLF V3 pack passed all eight tests without any adverse events.
- Where can I obtain the full UN38.3 test report for the V3 battery pack?
