Bulk battery shipping across long distances (like Europe or South Africa) often leads to friction damage or leakage. How do you package the HQ-50S model to prevent transport risks?
We use custom heavy-duty packaging specifically designed for compliant Dangerous Goods (DG) transit. Every single HQ-50S battery is individually insulated and securely placed in anti-static blister trays. This completely prevents cells from rubbing against each other, ensuring your bulk wholesale shipment arrives at your warehouse in pristine, ready-to-sell condition with full MSDS & UN38.3 protection.
How does your material sourcing process protect our repair business from getting low-grade, refurbished battery cells?
We practice strict direct material buying. We deal only with tier-1 contract cell manufacturers and refuse to let assembly lines use cheap, non-standard components to lower costs. By matching pure cobalt cells with premium protection boards (ICs), we lock in a 100% stable voltage foundation, giving your repair chains consistent original-spec fittings.













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.
Yes, for wholesale buyers looking to scale up, we provide premium OEM services. We can handle custom battery body silk-printing, custom-branded retail boxes with anti-static EVA foam or blister inserts, and warehouse barcode stickers.
Our minimum order quantity is 100 pcs per order. Mixed models are supported. Send your model list and quantities for wholesale pricing; our team will reply within 12 hours. If you need samples for business evaluation before a bulk order, include your company details and expected purchase plan in your inquiry.
Yes. We supply brand-new replacement batteries with professional inspection before shipment.
Each batch is checked for capacity, voltage, internal resistance and overall performance consistency.
Every batch follows quality inspection procedures, including:
This helps maintain stable performance and reduce after-sales issues.
