Certifications and Quality Control
Compliance documents are what turn a datasheet into an order. Below are the certificates and test reports we hold, how quality is controlled on the production line, and which documents travel with a lithium battery shipment.
Certifications and test reports
| Document | Scope | Reference |
|---|---|---|
| ISO 9001 quality management system | Company-wide | — |
| ISO 14001 environmental management system | Company-wide | — |
| CE — Low Voltage Directive (LVD) | Product certification | 2026AT0427548 |
| CE — LVD test report | Test report | 2026AT0427548S |
| UL certification | Applicable models | — |
| UN38.3 transport test | LD4850-PRO battery pack | SWT25160111B01A-M0 |
| MSDS safety data sheet | LD4850-PRO battery pack | SWT25160111B01D-M0 |
| Sea-transport report | LD4850-PRO battery pack | — |
Certificates and test reports are supplied with your quotation on request. Where a certificate carries a reference number, that number is the one your compliance team can check — which is why we publish it here rather than describing the certification in prose.
How we control quality
- Cells — new-production Class A LiFePO4 cells only. Never second-life or re-wrapped cells, which is the single most common way a cheap lithium UPS fails early.
- Platforms — DSP-controlled designs with comprehensive protection, rather than analogue control boards.
- Testing — 100% production-line testing on every unit before packing, not batch sampling.
- Management system — production runs under ISO 9001 quality management and ISO 14001 environmental management.
- Traceability — test records and production documentation can be provided with the shipment.
Because the product lines are built on our own Shenzhen lines rather than sourced from anonymous upstream factories, a quality problem is something we can investigate to root cause instead of forwarding to a supplier.
Shipping documents
Lithium batteries are dangerous goods, and the paperwork is not optional. For battery packs such as the LD48V series we provide:
- UN38.3 test report — the transport test every lithium cell and pack must pass before it can fly or sail.
- MSDS — the material safety data sheet your forwarder will ask for.
- Sea-transport report — the additional document required for ocean freight of lithium batteries.
The same document set applies to the packs inside every energy storage system we ship, not only to standalone battery orders — a containerised BESS is a lithium shipment like any other and is booked as one.
These are issued with the quotation or before dispatch, not after the forwarder rejects the booking. If your market requires a specific national approval, tell us at inquiry stage — see the OEM/ODM process for how projects with certification requirements are handled.
For anything not covered here, ask through the contact form and we will send the actual document rather than a description of it.
