Rigorous Testing and Safe Transport
We prioritize battery safety in both design and transport. Each product undergoes final testing to ensure performance before shipment, guaranteeing that you receive high-quality products.
Packing and Transport
Safe transport is paramount for lithium batteries. Our robust packaging, often using plywood boxes for batteries over 12kg, has been tested for safe shipping via road, sea, or air. We recommend shipping a minimum of 1 pallet to reduce shipping costs and ensure the protection of your products during transit.

Prismatic Lithium Cells: Revolutionizing Battery Design
Prismatic lithium cells are designed for high energy density, making them ideal for large battery pack configurations. Compared to cylindrical cells, prismatic cells offer higher amp-hours per cell, allowing for greater capacity. They are perfect for energy storage systems, replacing traditional sealed lead-acid batteries, and providing more efficient and reliable energy storage solutions.
Advantages of Prismatic Lithium Cells:
- High Energy Density: Optimized for large-capacity applications.
- Ensured Consistency: Advanced automated production ensures uniformity in every cell.
- Stable Voltage Platform: Low internal resistance, high discharge rate, and stable voltage.
- Safe and Reliable: Lithium iron phosphate (LiFePO4) chemistry is the safest among all lithium battery types.
