Standards & Compliance
The ETENWOLF S0 battery pack was evaluated under the following standard:
| Standard | Full Title | Applicability |
|---|---|---|
| IEC 62133-2:2017+AMD1:2021 | 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 | Primary test standard |
| EN 62133-2:2017+AMD1:2021 | European harmonized equivalent of IEC 62133-2 | EU market compliance |
IEC 62133-2 is the globally recognized safety standard for lithium-ion cells and battery packs used in portable consumer devices. It mandates rigorous abuse testing — including short-circuit, overcharge, thermal, mechanical, and vibration tests — to ensure cells will not catch fire, explode, or leak under foreseeable misuse conditions. Compliance with this standard is a prerequisite for market access in many regions, including Europe (via CE marking under relevant directives) and other international markets.
The testing was performed entirely at the Waltek Testing Group Co., Ltd. facility, a nationally accredited testing and certification body operating under CNAS accreditation in China.
Validity & Certification Body
The test report WTH25D09245618B was prepared and approved by qualified engineers at Waltek Testing Group Co., Ltd. and is valid as a full compliance record for the battery model tested.

Frequently Asked Questions
- What does IEC 62133-2 certification mean for the ETENWOLF S0?
-
IEC 62133-2:2017+AMD1:2021 is the internationally recognized safety standard for lithium-ion battery packs used in portable devices. For the ETENWOLF S0, passing this standard means its internal 2S1P-1200 battery pack has been independently verified to resist dangerous failures such as fire, explosion, or leakage under a comprehensive set of electrical, thermal, and mechanical abuse conditions.
- Which tests were performed on the S0 battery pack, and did it pass all of them?
-
Yes. The ETENWOLF S0 battery pack was subjected to 12 distinct test procedures under IEC 62133-2, including continuous charging at constant voltage, external short-circuit (cell and battery level), free fall, thermal abuse, crush, overcharge, forced discharge, vibration, mechanical shock, and forced internal short-circuit design evaluation. All tests were passed.
- Who conducted the IEC 62133-2 testing and is the laboratory accredited?
-
Testing was conducted by Waltek Testing Group Co., Ltd., located in Dongguan, Guangdong, China. Waltek is a CNAS-accredited third-party testing laboratory with broad international recognition. The report was compiled by Jason Zhen (Project Engineer) and approved by Deval Qin (Designated Reviewer), and the report reference number is WTH25D09245618B.
- Is this IEC 62133-2 report also valid for European CE marking purposes?
-
The test report confirms compliance with both IEC 62133-2:2017+AMD1:2021 and its European harmonized equivalent EN 62133-2:2017+AMD1:2021. This dual compliance is a key input for CE marking under relevant EU directives applicable to portable battery-powered devices. However, CE marking itself requires a full Declaration of Conformity and may involve additional directives depending on the end product.
