Measurement Uncertainty
No decision rule is specified by the IEC standard for comparing measurement results with applicable limits. Decisions on conformity were made without applying measurement uncertainty, using the simple acceptance decision rule (previously known as the accuracy method). Uncertainty calculations are based on criteria given by OD-5014 and are on file with the NCB and testing laboratory.
Standards & Compliance
The V3 battery pack was evaluated against the following applicable standards and schemes:
| Standard | Description |
|---|---|
| IEC 62133-2:2017 | Safety requirements for portable sealed secondary lithium cells and batteries — Part 2: Lithium systems |
| IEC 62133-2:2017/AMD1:2021 | Amendment 1 to IEC 62133-2:2017, updating safety test requirements for lithium systems |
| EN 62133-2:2017/A1:2021 | European harmonised standard equivalent; relevant for Republic of Korea national differences |
| IECEE CB Scheme | International framework for mutual recognition of safety test results across member countries |
| IECEE OD-2020-F1:2021, Ed.1.4 | TRF template used for structuring and documenting the test report |
The product also fulfils the requirements of EN 62133-2:2017/A1:2021 as confirmed through the Republic of Korea national differences evaluation appended to this report.

Frequently Asked Questions
- What is a CB Test Report and why does it matter for the ETENWOLF V3 battery?
-
A CB Test Report is issued under the IECEE CB Scheme, an international framework that allows safety test results to be mutually recognised across member countries. For the V3 battery pack, this report (No. 211-282250726-000) demonstrates that the product has been independently tested by TÜV SÜD and meets the safety requirements of IEC 62133-2:2017 and its Amendment 1:2021, facilitating market access in multiple countries.
- Which safety tests were performed on the V3 lithium-ion battery pack?
-
The V3 battery pack underwent 12 tests covering electrical, thermal, and mechanical safety scenarios.
