Li-Polymer packs are thinner and more flexible for compact designs. 18650 packs offer robust performance and higher capacity in a cylindrical format.
2. Can I customize the shape of the battery pack?
Yes. Li-Polymer packs can be shaped to fit any enclosure – curved, stepped, or ultra-thin.
3. What is the typical lead time for custom battery packs?
Engineering samples: 2-4 weeks. Mass production: 4-6 weeks after sample approval.
4. What certifications do you provide?
UL, CE, RoHS, UN38.3, and IEC62133. Full documentation included.
5. Do you ship globally?
Yes. We ship to North America, Europe, Asia, Australia, and beyond.
