Quality You Can Audit, Warranties With Numbers
Quality here is three gates and a paper trail: 100% incoming cell re-test at IQC, AQL 0.65 in-process control, and 100% end-of-line testing on every finished pack — all under an ISO 9001-audited QMS, with results tied to each module's barcode for the life of the product.
Quality & Certifications
Quality You Can Audit
Three inspection gates and a paper trail — 100% end-of-line testing on every finished pack, under an ISO 9001-audited QMS.
Document Pack
Certificates, Not Brochure Claims
Ask for the scans: UN38.3 test summaries per battery model, IEC 62133-2 CB reports, CE declarations and the ISO 9001 certificate with scope and expiry. Every document names the exact model it covers — a certificate that does not match the shipped model is not coverage.
What Travels With Every Order
- UN38.3 test summary — issued for the exact model on the packing list, all 8 test items.
- MSDS — 16-section safety data file formatted for carriers and customs.
- DG declaration — Class 9 sea freight under IMDG/P903 from Yantian or Shekou.
- SoC record — air shipments leave at ≤30% state of charge under PI965.
- Test data per lot — OCV and internal-resistance logs from the 100% end-of-line gate.
Compliance
Certified for EU and US Market Entry
Seven documents cover transport, market entry and factory audit. Certificate numbers, scopes and issue dates are shared on request — verify them against the issuing bodies before you rely on them.
Reading the Wall
What Each Certificate Actually Buys You
| Certification | What it covers | What it means for buyers |
|---|---|---|
| UN 38.3 | Transport safety — 8 tests: altitude simulation, thermal, vibration, mechanical shock, external short, impact/crush, overcharge, forced discharge | Globally mandatory. Without it a lithium battery cannot legally move by sea, air or road. |
| IEC 62133-2 | Sealed lithium cell and battery safety; CB Scheme mutual recognition | The de-facto EU entry standard for e-mobility and portable packs — one report covers many CB-member markets. |
| UL 1973 | Stationary ESS battery safety — cell to module to system | Core certification for US stationary storage; also the prerequisite step toward a UL 9540 system listing. |
| UL 9540A | Thermal-runaway fire propagation test method, cell to installation level | The data set US fire authorities (AHJ) and insurers ask for when approving an ESS installation. |
| CE | EU conformity — LVD, EMC, RED directives | Mandatory for EU sales; pairs with EU Battery Regulation 2023/1542 obligations your brand carries. |
| MSDS | 16-section chemical safety data sheet | Not a certificate but a hard requirement — carriers and customs reject freight without it. |
| ISO 9001 | Factory quality management system | Baseline your supplier-audit team checks first; our inspection gates below run inside this QMS. |
Warranty Policy
Warranty Terms by Product Line
| Product line | Warranty term | Performance floor and coverage |
|---|---|---|
| Home ESS — wall-mounted & stackable | 10 years | Capacity floor 80% of rated at year 10; 6,000+ cycles at 90–95% DoD |
| 19-inch rack modules | 10 years | Same 80% floor; parallel systems to 81.92 kWh (16 modules) covered as one system |
| RV & marine deep-cycle | 5 years | 4,000+ cycle platform; Bluetooth SOH log accepted as field evidence |
| E-bike & scooter packs | 24 months | Cell and BMS defects covered; cycle expectation 700–2,000+ depending on chemistry |
| Custom BMS boards | 24 months | Hardware defects plus firmware OTA and protocol updates through the term |
The 10-year ESS term matches what tier-one ESS brands publish — the difference is ours also covers OEM-labeled units, with warranty handled through your brand, not around it.
Three Inspection Gates
IQC, IPQC, OQC — Who Checks What, and When
- IQC — 100% incoming re-test — capacity and internal resistance verified per cell lot against the supplier grading report; A-grade EVE LF280K lots must measure ≤0.25 mΩ before release to the line.
- IPQC — in-process control — first-article approval, patrol checks each shift, weld pull-tests and voltage-balance sampling at AQL 0.65.
- Aging gate — 7-day full-charge hold with self-discharge curves screened against design-of-experiment limits; early-life failures never reach OQC.
- OQC — 100% final test — open-circuit voltage, internal resistance and insulation withstand on every unit, capacity per lot, then SoC calibrated to 30% for air-freight compliance.
Buyer Questions
Four Questions Compliance Teams Ask
Can we ship under your UN38.3 certificate?
Is your testing 100% or sampled?
What voids the 10-year home ESS warranty?
Can our QC team or a third party inspect before shipment?
