Large batteries like the iPhone 11 Pro Max have strict customs regulations. How do you handle global delivery safely?
We deeply understand that clearing customs is a major pain point for global importers. Our logistics process offers 100% Compliant Dangerous Goods (DG) Shipping with Full MSDS & UN38.3 Certification. We provide safe, direct-to-door delivery via Express, Air, and Sea freight across North America, Europe, South Africa, and the Middle East, making your import process completely hassle-free.
How do you ensure the internal safety and structural stability of these large-capacity iPhone 11 Pro Max batteries?
Every production run strictly follows customized engineering SOPs at our certified facilities. We use professional laser spot welding and multi-layer insulation to ensure precise flex-cable fitting under the on-site supervision of our technical team. Combined with individually insulated heavy-duty packaging, we guarantee zero loose batteries rubbing against each other during transport.













Cell chemistry, format, brand and grade depend on the selected product. LiFePO4 prismatic cells are not polymer pouch cells. For raw-cell orders, confirm the manufacturer, model, capacity, dimensions, terminal format, grading and test data before ordering. For replacement battery packs, confirm the compatible device and required cell/PCB configuration. Our real-world batch return rate is kept strictly below 0.3% through our 6-step testing process.
For our standard hot-selling catalog inventory, we can dispatch within 2-5 working days. For large-scale customized OEM or private label orders, production typically takes more days depending on material specifications. We always communicate real-time timeline tracking so you never experience local stockouts.
Our warranty is 12 months from the bill of lading (B/L) dispatch date. No returns to China are required. Send a photo or short video showing the unit SN/QR code and testing anomaly to your account manager. Valid claims are reviewed within 24 business hours. Approved claims may be resolved by replacement in the next shipment or invoice credit; batch defects exceeding 2% qualify for priority replacement dispatch at our cost. Coverage, exclusions and full procedures follow our B2B Support Policy.
