Key Details
The CB Test Certificate is backed by Test Report Ref. No. 085-28225184-000, which forms an integral part of the certificate. The report documents the full test program conducted on a representative sample of the battery pack. Key findings are summarized below.
| Item | Detail |
|---|---|
| Test Report Number | 085-28225184-000 |
| Test Sample | Rechargeable Li-ion Battery, model 3S4P-12400mAh |
| Conformity Result | Found to be in conformity with applicable standards |
| National Differences | See test report for country-specific national differences |
| Revision Status | Rev. 00 (initial issue) |
The 3S4P configuration means three groups of cells are connected in series to achieve the 10.8 V nominal voltage, with four cells in parallel per group to deliver the 12400 mAh capacity. This architecture is common in high-drain portable power tools such as the ETENWOLF Vortex S7.
Standards & Compliance
The battery pack was evaluated against the current edition of the primary international standard governing the safety of secondary lithium cells and batteries for portable applications, including its first amendment.
| Standard | Title / Scope |
|---|---|
| IEC 62133-2:2017 | Secondary cells and batteries containing alkaline or other non-acid electrolytes — Safety requirements for portable sealed secondary lithium cells, and for batteries made from them, for use in portable applications — Part 2: Lithium systems |
| IEC 62133-2:2017/AMD1:2021 | Amendment 1 (2021) to IEC 62133-2:2017 — updates to safety test requirements for lithium secondary cells and batteries |
IEC 62133-2 covers a comprehensive battery safety test program including overcharge, forced discharge, external short circuit, free fall, thermal abuse, crush, and vibration tests, among others. Conformity with this standard and its 2021 amendment demonstrates that the battery pack in the ETENWOLF Vortex S7 meets internationally recognized safety benchmarks.
