The 2x3 18650 Battery Holder is designed to securely hold six 18650 lithium-ion cells in a 2-row by 3-column arrangement. Made from high-quality, flame-retardant ABS plastic, it ensures a precise 18.5 mm bore fit for each cell, providing stability, insulation, and safety during assembly. Its design prevents short circuits and allows airflow for heat dissipation, making it ideal for building medium-capacity battery packs for e-bikes, solar power storage, and custom electronics projects.
