Need Cells With Custom Tabs?
We can supply battery cells with custom welded tabs for manufacturing, research, aerospace, robotics, and battery pack production applications. Custom tab designs can reduce assembly time and simplify integration into your project.
Battery Testing & Verification
Many of our cells are independently tested and verified. Capacity testing, discharge analysis, internal resistance measurements, and performance data are available on select products. Contact us for testing information or project-specific recommendations.
Custom Battery Packs Without a BMS
For robotics, aerospace, UAV, military, laboratory, and engineering projects, we can build custom battery pack configurations without a Battery Management System (BMS) installed.
This allows customers to integrate their own electronics, flight controllers, power distribution systems, or proprietary BMS solutions while still receiving a professionally assembled battery pack.
