FAQ
Frequently asked questions
Seven questions B2B buyers ask before sending a quote request. If yours isn't here, the contact form above reaches our team directly.
Are you a factory or a trading company?
We are a direct manufacturer based in Chongqing, China. Our facility handles cell grading, BMS assembly, and pack integration in-house — no trading middlemen. This is why our pricing is typically 20–40% below what importers pay through agents. We welcome third-party audits (SGS, BV, TÜV) and on-site visits by appointment.
What is your MOQ for OEM/ODM orders?
MOQ varies by product line:
- Stock SKUs (EV packs, standard cells): 1 unit for sample orders, 10–20 units for wholesale
- Custom configurations (24V/36V/48V/72V storage packs): typically 50 units
- Full OEM/ODM with branded packaging: 100 units minimum, price breaks at 500 / 1000 / 5000
Sample orders ship within 7 days so you can verify fitment before scaling.
How do I verify a battery fits my vehicle?
Every EV battery SKU on this site ships with the manufacturer's original OE number stamped on the product page. Match by OE number — that's the same reference Toyota, Honda, BYD, or Tesla use internally. Identical OE = direct fitment, no modification, no diagnostic re-coding required for most hybrid applications.
If you can't find your OE number in our catalog, send it via the contact form and we'll cross-reference within 24 hours. We also support custom builds for rare or legacy models.
Which certifications do your batteries carry?
Our manufacturing and exported products meet the five core international certifications required for global B2B sale and lithium-battery transport:
- IATF 16949 — Automotive QMS
- ISO 9001 — Quality management
- UN38.3 — Transport safety
- CE — EU market access
- IEC 62133 — Cell safety standard
Specific certification scope varies by product line and model — request the technical dossier for your application.
How do you ship lithium batteries internationally?
All lithium battery shipments are UN38.3-tested and certified for air, sea, and ground transport. We ship worldwide via:
- Sea freight (FCL/LCL): most economical for 100+ units, 25–40 days transit
- Air freight: DHL/FedEx for urgent samples, 5–10 days door-to-door
- Express courier: small parcels and documents, 3–7 days
We handle EXW, FOB, CIF, DAP, and DDP terms and provide MSDS, UN38.3 test reports, and commercial invoices with every shipment.
What payment methods do you accept?
Standard terms for new buyers: 30% T/T deposit, 70% balance against B/L copy. For repeat orders and strategic partners we offer open-account terms (Net 30/60).
Other accepted methods: L/C at sight (orders over USD 50,000), Western Union for small samples, and PayPal for orders under USD 3,000. Trade Assurance via Alibaba also supported.
What is your typical lead time?
Lead time depends on order type:
- Stock SKUs (in our warehouse): ships within 7 business days
- Standard catalog orders: 15–25 days from PO confirmation
- Custom OEM/ODM: 25–40 days, including BMS calibration and aging tests
