⚙️ Choose Your Premium Cell Configuration

All packs use 70 genuine 21700 cells (14S5P) and 0.5 mm custom-cut copper busbars rated to handle 300 A continuous — delivering more current with less heat and voltage sag.

Our proprietary 0.5 mm copper busbars ensure ultra-low resistance and efficient current flow.
Each connection uses 0.2 mm nickel/copper composite welds, creating secure, high-conductivity bonds for consistent power delivery.
