Voices from Our Long-Term Partners

Real collaboration is about solving problems together. These are the honest experiences of the engineers and managers we support every day.

"Our previous supplier rejected us due to small initial volumes. LithoTop spent a weekend debugging our BMS logic to match our motor current. They are genuine partners, not just a vendor."

FAQ

Answering your final questions about battery performance, certifications, and global shipping.

We prioritize BMS logic matching as our core competitive edge. By conducting manual code audits and pre-production sampling, we ensure the battery integrates perfectly with your hardware to prevent system crashes.

We execute 100% OCV and IR inspection on every batch. Using high-purity cobalt for our LiPo cells, we eliminate the common swelling issues found in lower-tier suppliers, especially for high-rate UAV and medical applications.

Yes. We have 360+ models already certified with UL, KC, PSE, CE, and IEC62133. If your project requires a new certification for the US or Korean markets, we provide full technical documentation and support to complete the process.

Yes. Many models carry UN38.3/MSDS, and we support new certifications as needed. Expert air, sea, and express shipping to the US, EU, and Korea ensures safe, compliant delivery.

For cylindrical packs (18650/21700), we generally have no MOQ as we keep cell stock. For custom LiPo cells, it depends on capacity: 3K-5K units for large cells and up to 20K for micro-cells (under 100mAh).

Unlike larger manufacturers who often neglect small-to-medium projects, we offer high flexibility during the R&D stage. We provide 3-5 free samples for LiPo projects and dedicate our technical team to help optimize your hardware’s internal space.
