Step 1: ​How It’s Made

After are assembled in “honeycomb form” (more compact geometric matrix, and too for better cooling inside pack through heat dispersion between metal bodies of the cells), the battery cells terminals are over-insulated, and joined by nickel-strips layer through pulse-welding dependent upon the configuration. Then wiring-harnesses for PCB/BMS, high quality polarized connectors, and custom shielded discharge cables are applied, spending more attention to detail and safety elements. The entire cells block are surrounded by a light multilayer insulating shield with mechanical and dielectric strength, outside-reinforced with a thin laminate aluminum foil, sealing and resilient. To reduce manufacturing costs, the battery pack are wrapped with a hard PVC film. The aesthetic appearance isn’t charming, however we work hard to develop a tough and lightweight battery housing, from composite materials.
