FAQ

Frequently Asked Questions

Common questions from importers, distributors, and pack manufacturers.

Prismatic cells use a flat, rectangular form factor and are ideal for large-scale ESS, solar storage, and EV battery packs due to their high capacity per cell (up to 314Ah). Cylindrical cells (18650, 21700) are round-format cells suited for power tools, e-bikes, drones, and consumer electronics where compact packaging and high discharge rates matter.
We offer flexible MOQ across all cell types. Sample orders are accepted for first-time buyers who want to test quality before committing to a larger purchase. Contact us with your required cell type, capacity, and destination country for a specific MOQ and pricing breakdown.
