LiFePO4 Battery FAQ — MOQ, Shipping, Certifications & OEM

For standard configurations, our MOQ is 10 units for wholesale pricing. We also accept 1-unit sample orders for pre-qualification testing — the sample cost is credited back to your account on your first bulk order of 10+ units.

For OEM/ODM custom configurations (private label casing, custom firmware, branded apps), MOQ is typically 20–50 units depending on the customization scope.

Yes. We strongly encourage it. A single-unit sample lets you verify capacity, BMS behavior, communication protocol compatibility (CAN/RS485/RS232), and physical dimensions before placing a larger order. Sample orders ship within 5–7 working days via express courier (DHL/FedEx/UPS).

Order Type	Lead Time
Standard configuration (in stock)	3–7 working days
Standard configuration (production run)	15–30 working days
OEM / Custom configuration	30–45 working days

Lead time is confirmed in writing on your Proforma Invoice (PI) and depends on order volume and current factory schedule.

Yes. Every order receives a formal PI with itemized pricing, HS code, packaging details, and bank information. Before shipment, we provide real-time photos and/or video of your goods on the production line and at final QC inspection.

We support EXW, FOB (Shenzhen/Ningbo), CFR, and CIF. For LCL or pallet-level shipments to the EU/UK, we can also arrange DAP delivery through our freight partners. Tell us your destination port or warehouse address and we’ll quote the most cost-effective option.

Yes. All cells are UN38.3 certified, which is the mandatory safety certification for lithium battery air transport (IATA DGR Class 9). Sample units (1–2 pieces) are commonly shipped via air. For bulk orders, sea freight (FCL/LCL) is recommended for cost efficiency given the ~120kg unit weight.

Each unit is packed in a reinforced export carton with foam corner protection, palletized, and shrink-wrapped (package size 880×625×427mm, ~137.5kg gross). Pallets are stackable and sized to optimize 20’/40′ container loading. Custom packaging/labeling (private label cartons) is available for OEM orders.

Yes. We provide a complete export document package: commercial invoice, packing list, UN38.3 test summary, MSDS, certificate of origin, and DG declaration (for air/sea as applicable). Our logistics team coordinates directly with your forwarder to avoid customs delays.

Level	Certifications
Battery Pack	CE, MSDS/SDS, UN38.3
Battery Cell	CE, IEC 62619, UL 1973, RoHS
System Standard	UL 62133-2, CSA C22.2 #62133-2, UL 2054

All certificates are current and copies are provided with every shipment. Original certificate PDFs (for tender/bidding submissions) are available on request.

Our cells use cobalt-free LiFePO4 chemistry, which aligns with the direction of the EU Battery Regulation (2023/1542) on hazardous substance restrictions. We can support carbon footprint declarations and due diligence documentation as required — contact our compliance team for the latest documentation status.

Yes. UN38.3, IEC 62619, and UL test reports are issued by accredited third-party labs. We can provide redacted copies for general reference, or full reports under NDA for tender submissions and importer registration purposes.

The battery’s BMS communicates natively via CAN bus (500kbps) or RS485/RS232. Verified compatibility includes Deye, Solis, Goodwe, Growatt, Sofar, SMA, Victron, Fronius, Solax, Huawei, and Fox ESS. If your target inverter brand isn’t listed, send us the model number and we’ll confirm the protocol mapping or provide a custom CAN configuration.

Up to 15 units can be connected in parallel (max 230.4kWh). One unit is designated as the “master” via an address-selection switch and communicates the aggregated SOC/SOH/alarm status to the inverter — no external controller is required.

Discharging is rated down to -20°C. However, like all LiFePO4 cells, charging below 0°C is not recommended without the optional Self-Heating Kit, which automatically warms the cells to a safe charging temperature (0–55°C) before allowing charge current. We recommend this option for installations in Northern Europe, Canada, and the Northern US.

Nominal capacity (15.36kWh) is the total stored energy. Usable capacity is what can be discharged before the BMS cuts off to protect cell health — at 90% DOD, usable energy is approximately 13.8kWh. We recommend sizing system designs around the usable figure.

Yes. The optional Bluetooth telemetry module pairs with our iOS/Android app for live SOC, SOH, voltage/current, and alarm history. For OEM/ODM partners ordering 50+ units, a white-label version of the app (your branding, your app store listing) can be arranged.

Yes — full OEM/ODM service is available, including:

• Custom enclosure laser-etching or silk-screen branding
• Custom firmware splash screen / LCD branding
• White-label packaging, cartons, and user manuals
• White-label monitoring app (iOS/Android)

Minimum order quantities and lead times vary by customization depth — see “Ordering & MOQ” above.

Within safe operating limits, yes — charge/discharge cut-off voltages, CAN protocol mapping for specific inverter brands, and balancing thresholds can be adjusted at the firmware level for qualifying order volumes. Our engineering team will review your requirements before confirming feasibility.

Yes. Distributors receive editable datasheet templates, product photography, 3D renders, and installation manuals in English (other languages on request) to support local marketing and tender submissions.

Each battery pack carries a 5-year manufacturer warranty covering manufacturing defects, BMS failure, and capacity degradation beyond rated specifications (subject to normal use within rated temperature/current limits). The cells themselves are designed for a 10-year service life / 6,000 cycles @ 80% DOD.

Report any transport damage or DOA (dead-on-arrival) units within 7 days of receipt with photos/video and the unit serial number. After verification, we will ship a replacement unit or component, or issue a credit note — whichever is more practical for your shipping route.

Our pre-sales and after-sales engineering team responds within 24 hours on business days via email, and we offer scheduled video calls to accommodate European and North American time zones. Installation manuals and CAN protocol configuration guides are also available in our Download Center.

Yes. We stock common spare parts including BMS boards, busbars, terminal connectors, and casing components for distributors who maintain local service inventory — recommended for orders of 20+ units.

We accept T/T (bank wire transfer), L/C at sight for larger orders, and PayPal for sample orders. Standard terms are 30% deposit / 70% before shipment for bulk orders, negotiable for repeat customers.

Yes. Pricing is tiered: sample (1 unit), wholesale (10–49 units), and volume (50+ units) tiers each have progressively better unit pricing. Submit your target quantity and destination country in the quote form for an accurate FOB/CIF quote.

Yes. For distributors committing to quarterly or annual purchase volumes, we offer fixed-price agreements that protect against raw material (lithium carbonate) price fluctuations for the agreed period — contact our sales team to discuss terms.
