Manufacturing Process

Each SBB battery is hand-built in Spain by Siliconbirds, using top-quality components and strict production controls to ensure reliability, safety, and consistency across packs.

• Cells are selected and grouped according to electrical characteristics.

• Honeycomb-style cell holders with three layers increase rigidity and pack stability.

• Spot welding with 0.2mm x 10mm nickel strips, reinforced with 0.4mm areas for improved current conduction.

• Silicone padding between cells improves impact absorption and insulation.

• Kapton tape protection prevents potential short circuits from balance wires.

• Internal insulation with adhesive dielectric material.

• Final encapsulation in high-strength shrink wrap.

This process ensures a safe, reliable, and FPV-ready battery pack.
