Quality and Certifications

Management system certifications: ISO 9001 and ISO 14001

The company holds ISO 9001 certification for quality management and ISO 14001 certification for environmental management. For a buyer screening custom lithium battery manufacturers, these two certificates answer different questions: ISO 9001 covers how design, purchasing, production and testing are controlled and recorded, while ISO 14001 covers how environmental aspects of the operation are managed. The scope of each certificate is stated on the document itself.

An iso 9001 battery manufacturer is expected to show controlled processes rather than a single final inspection. In practice this means incoming materials are checked against criteria, build steps are recorded, nonconforming work is segregated, and test results are traceable to the pack that was shipped. The management system is what holds those steps in place across every order, not only the first one. The company is also a National High-Tech Enterprise and holds multiple utility model patents; the patent certificates are displayed alongside the management system certificates on this page. More background on the company is on about Jetray Technology.

The certificate images on this page include the ISO 9001 certificate, the ISO 14001 certificate, an IECQ conformity certificate, utility model patent certificates, a Guangdong contract-honoring enterprise plaque and the high-tech enterprise certificate. Buyers often ask for these before a supplier audit, so they are published here rather than sent only on request. If you need a copy for your own supplier file, use request certificate copies and state which document you need and the name your purchasing team will file it under. Certificate scope and the standards each document is issued against are read from the certificate itself.

Product documents by model: UN38.3, IEC 62133, MSDS

Management system certificates cover the factory. Transport and product safety documents cover the pack you are buying, and they are issued per model. UN38.3, IEC 62133 and MSDS documents can be confirmed and provided for specific models — tell us the model you are buying and we will confirm which documents cover it. This distinction matters at the procurement stage: a certificate for one pack configuration does not automatically transfer to a pack with a different cell, enclosure or protection circuit. When you shortlist a battery pack manufacturer, ask for the document set by model name, not by factory. The same applies to shipping: freight forwarders ask for UN38.3 and MSDS against the exact pack being moved, so confirm the model reference before booking transport. Where a project needs a pack built to a new specification, document coverage is agreed while the specification is written, not after tooling.

Incoming cell control and pack testing

Cells are sourced from established cell makers and checked on incoming inspection before they enter production. Checks cover the cell as received, and cells are matched within a pack build so that the cells inside one pack are consistent with each other. Matching at build stage is what protects series and parallel configurations: in a 3S2P pack, for example, weak cells in one parallel group limit the whole string, so grouping is done from measured cell data rather than from the carton label.

Pack-level charge and discharge tests and an aging step run before delivery. These are process steps applied to the finished pack, and the results form part of the record traceable to that pack. For buyers comparing custom battery solutions, the practical question to ask any supplier is what is tested on the finished pack versus what is only tested on the cell — the two are not the same, and pack-level testing is where assembly faults such as connection resistance or a protection circuit fault show up. Test content for a specific project is confirmed in the project specification, since not every pack carries every option.

Frequently Asked Questions

What quality system certifications does the company hold?

The company holds ISO 9001 certification for quality management and ISO 14001 certification for environmental management. It is also a National High-Tech Enterprise and holds multiple utility model patents. The certificate images, including the ISO 9001 and ISO 14001 certificates, an IECQ conformity certificate and the patent certificates, are displayed on this page. The scope and issuing standard for each document are stated on the certificate itself.

Can we see the certificates?

Yes. The certificate images are published on this page, including the ISO 9001, ISO 14001, IECQ conformity, utility model patent, Guangdong contract-honoring enterprise and high-tech enterprise documents. If your supplier file needs a copy, use request certificate copies and name the document you need. For product-level documents such as UN38.3, IEC 62133 and MSDS, tell us the model you are buying so coverage can be confirmed against that model.

How is incoming cell quality controlled?

Cells are sourced from established cell makers and checked on incoming inspection before production. Cells are then matched within a pack build, so the cells inside one pack are consistent with each other — a step that matters for series and parallel configurations. After assembly, pack-level charge and discharge tests and an aging step run before delivery, and the results are recorded against the pack.
