02 Application and certification

Application and certification requirements determine the design approach and the lead time.

Application * Please select Testing / development / research project (one-off build) Sample / exhibition / prototype (one-off build) Special custom build (tailored design) Consumer sales / off-the-shelf replacement / volume production Other

Certification status (select all that apply)

Not applicable To be reviewed at volume production IEC 62133 KC 62133 IEC 62619 KC 62619 UN38.3 EMC

* Custom build items do not include certification by default. If certification is required, we agree on a build spec that meets the certification conditions and then proceed through a certification agency process.

Design for future certification

Not applicable Design / build must allow for certification

* Regardless of certification, a standard BMS with protection functions (overcharge, overdischarge, overcurrent, overheat), structural insulation and safety design are always included.

03 Electrical specifications See a worked example

The specification is driven by load characteristics and operating environment. Enter only the values you know, as accurately as you can. (BMS monitoring 20% by default · for 1% precision, select under special functions below)

[Required] Consent to the collection and use of personal information

• Items collected Company (organization) name, contact person's name, phone number, email, and the inquiry / requested specification details you enter
• Purpose of use Preparing and replying to quotations, technical consultation, and contract- and delivery-related communication
• Retention period Destroyed without delay after one year from completion of the inquiry
• Right to refuse You may refuse consent; however, in that case the handling of your inquiry, including quotation replies, may be limited.
• For details, please see our Privacy Policy.

I agree to the collection and use of my personal information as described above. *

[Required] Custom-build process notice · Non-certified manufacturing policy

• This requirement specification sheet is used as the basis for preparing your quotation, so please fill it in accurately and in detail.
• Custom battery packs are manufactured on a non-certified basis by default. Certification (KC, IEC 62133/62619, UN38.3, EMC, etc.) does not proceed automatically and is arranged separately by prior consultation.
• Certification requires additional testing costs and separate test samples, and the testing period takes approximately 8–16 weeks.
• If certification is requested afterwards for a product designed without the certification requirements reflected, additional development and redesign costs may apply.
• Responsibility for managing the final operating environment, obtaining product certification and complying with applicable laws, and for the sale, distribution, and end-product certification of the product rests in principle with the user.

I have read and agree to the custom-build process notice and the non-certified manufacturing policy above. *
