Standards & Compliance
The ETENWOLF S1 battery pack was evaluated and declared conformant to the following Korean national safety standard, which is harmonized with the international IEC standard for secondary lithium cells and batteries used in portable applications.
| Standard Reference | Full Title | Scope |
|---|---|---|
| KC 62133-2 (2025-10) | 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 | Safety testing of lithium-ion cells and battery packs used in portable consumer devices |
Key test areas covered under KC 62133-2 include:
- Overcharge and over-discharge protection
- Short-circuit protection (external and internal)
- Crush, impact, and vibration resistance
- Thermal abuse and thermal runaway assessment
- Charging and discharging cycle performance
- Insulation resistance and dielectric strength
Compliance with KC 62133-2 also satisfies South Korea’s product safety notification requirements under Articles 28 and 29 of the Electrical Appliances and Consumer Products Safety Control Act. The KC mark must be displayed on the product and its packaging in accordance with Article 37 of the same Act’s enforcement rules.
Validity & Certification Body

Frequently Asked Questions
- What does the KC certificate XU104192-25001 confirm for the ETENWOLF S1?
- It confirms that the lithium battery pack (model 2S1P-2600, 7.4 Vdc / 2,600 mAh) installed in the ETENWOLF S1 meets the safety requirements of KC 62133-2 (2025-10). The certificate was issued by Korea Testing Certification Institute under receipt number KCA2025-18374 and is valid as long as the product is manufactured without changes to the registered components or factory.
- Which standard was used to test the ETENWOLF S1 battery, and what does it cover?
- KC 62133-2 (2025-10) is the applicable standard. It is the Korean national implementation of IEC 62133-2 and covers safety requirements for portable sealed secondary lithium cells and battery packs, including overcharge, short-circuit, thermal abuse, vibration, and mechanical integrity testing.
- Can the registered critical components in the ETENWOLF S1 battery be changed without notifying the authority?
- No. Any change to the components listed in the certificate — including the lithium-ion cells (ICR18650), ICs (U1–U4), MOSFET (Q10), or fuse (F1) — requires a formal revision application (안전확인변경신고) to the certification body before implementation. Unauthorized changes may result in administrative sanctions under the Electrical Appliances and Consumer Products Safety Control Act.
- Is the KC mark on the ETENWOLF S1 sufficient for sale throughout South Korea?
- The KC Safety Confirmation mark covers the battery pack’s compliance with electrical safety standards under the Electrical Appliances and Consumer Products Safety Control Act. However, the certificate itself notes that products subject to other applicable Korean laws may require additional approvals or permits beyond this safety confirmation.
