Packaging Method:
Each cell is individually wrapped in protective insulation (e.g., soft foam, PE sleeve, or anti-static bag) to prevent mechanical damage and short circuits during transit.
Intermediate Packaging:
Cells are arranged in sturdy cardboard or fiberboard boxes with separators or honeycomb trays to avoid contact between cells and to ensure mechanical stability.
Outer Packaging:
Heavy-duty, UN-certified cartons with cushioning materials protect the cells from vibration and impact. Palletized shipments use reinforced shrink wrap for added security.
Labeling:
All cartons are clearly marked with required labels, including:
UN3480 or UN3481 (for lithium-ion batteries, depending on if cells are shipped alone or with equipment)
"Lithium-ion batteries" caution labels (Class 9)
Handling instructions and appropriate hazard labels per IATA/IMDG regulations
1.If it needs to be stored for a long time (more than 3 months), the cells should be stored in an environment with a temperature range of -10~25℃, in a dry, well-ventilated area, away from direct sunlight and heat sources.
2.Avoid stacking heavy objects on top of battery cartons.
3.Ensure packaging remains intact and undamaged prior to use.
1.What are the main applications of the 40135FS battery?
The 40135FS cell is primarily used in electric vehicles (EVs)—including electric cars, buses, and e-bikes—and in energy storage systems (ESS) for residential, commercial, and grid-level storage. Its high capacity and long cycle life make it ideal for these demanding applications.
2.Can the 40135FS cell support fast charging?
Yes! It supports standard charging at 1.5C and can handle discharge rates up to 3C for short periods, depending on the system design and thermal management.
3.Can the 40135FS cell be connected in series or parallel?
Yes. The cell can be configured in series to achieve higher voltage or in parallel to increase capacity. Ensure proper battery management systems (BMS) are used for balancing and safety.
4.Who should I contact for technical support?
For detailed specifications, customization options or technical support, you can contact us through the company's official website or leave your requirements. Our colleagues will contact you and send you the relevant documents or answers.
