The KC marking on the Air3 battery pack must comply with the marking requirements of Article 37 of the Enforcement Rule of the Electrical Appliances and Consumer Products Safety Control Act.
Standards & Compliance
The battery pack in the ETENWOLF Air3 was evaluated against the following standard under the South Korean KC certification scheme:
| Standard | Edition / Date | Scope |
|---|---|---|
| KC 62133-2 | 2025-10 | Safety requirements for portable sealed secondary lithium cells and batteries for use in portable applications — Part 2: Lithium systems |
KC 62133-2 is the Korean national adoption of IEC 62133-2, covering electrical, mechanical, and environmental safety tests for lithium secondary battery systems. Tests include overcharge, over-discharge, short-circuit, crush, thermal abuse, and vibration evaluations, among others.
The certificate holder is required to:
- Conduct self-inspection (자체검사) during production and maintain records.
- Ensure no registered critical component is omitted or arbitrarily changed without a formal revision application.
- Refrain from applying the KC mark before certificate issuance or after suspension or cancellation of the certificate.
Validity & Certification Body
The Confirmation Letter of Declaration (안전확인신고증명서) for the Air3 battery pack is valid as long as the following conditions are continuously met:
- The product is manufactured exclusively at the declared factory: Mozhen Technology (Shenzhen) Co., LTD, Shenzhen, Guangdong, China.
- The product continues to conform to the applicable safety standard KC 62133-2 (2025-10).
- No changes are made to the critical components, factory address, representative, or company name without prior notification and re-issuance of the certificate.
Should any of the following events occur, a certificate revision application must be submitted to the certification authority before continuing production:
- Changes to manufacturer name, representative, or address.
- Addition, modification, or removal of series/derived models.
- Addition or change of safety-critical components listed in the technical document.

Frequently Asked Questions
- What does the KC certificate XU104192-26002 confirm about the Air3 battery pack?
-
It confirms that the 2S1P-1300 lithium battery pack (7.4 V DC, 1300 mAh) used in the ETENWOLF Air3 has been evaluated and declared compliant with the Korean safety standard KC 62133-2 (2025-10) by the Korea Testing Certification authority (KTC). The certificate was issued on 2026-01-30 under application number KCA2026-01402.
- Is the KC mark the same as CE or other international certifications?
-
No. The KC mark is South Korea’s mandatory safety mark under the Electrical Appliances and Consumer Products Safety Control Act. It is a national requirement specific to the Korean market. It is separate from CE marking (European Union), FCC (United States), or other regional certifications, though the underlying test standard KC 62133-2 is closely aligned with the international standard IEC 62133-2.
- Can the critical components in the Air3 battery pack be changed without re-certification?
-
No. Any addition or change to the safety-critical components listed in the technical document — including the Li-ion cells (Dongguan Hanwei 953737), the charging IC (IP2320), the microcontroller (CMS8S6990-QFN24), or the protection MOSFET (KS3222MB) — requires a formal certificate revision application to KTC before the change can be implemented in production. Unauthorized changes may result in administrative action under the Act.
- Where can I verify the authenticity of this KC certificate?
-
Authenticity can be verified through the Korea Testing Certification (KTC) customer service portal using the document management number embedded in the certificate. The original certificate also carries a time-stamp verification seal and a 2D barcode. Note that the document management number should not be exposed when submitting copies of the certificate to avoid unauthorized access to the technical document contents.
