Standards & Compliance
The ETENWOLF V3 battery pack was evaluated against the following Korean and international safety standards:
| Standard | Description | Version |
|---|---|---|
| KC 62133-2 | Safety requirements for portable sealed secondary lithium cells and batteries for use in portable applications — Part 2: Lithium systems | 2020-07 |
KC 62133-2 is the Korean national adoption of IEC 62133-2 and mandates testing for overcharge, overdischarge, short-circuit, thermal abuse, mechanical shock, and other safety scenarios applicable to lithium-ion battery packs.
Compliance obligations for the certificate holder include:
- Maintaining the KC Mark display in accordance with Article 37 of the Enforcement Rule of the Electrical Appliances and Consumer Products Safety Control Act.
- Conducting ongoing self-inspection of production units and maintaining inspection records.
- Producing units only at the registered factory (Guangdong Bestek Technology Co., Ltd., Heyuan City, Guangdong, China).
- Applying for a certificate revision before changing any registered critical component, manufacturer name, factory address, or representative.
