The 3S 18650 Battery Holder is designed to securely hold three standard 18650 lithium‑ion cells connected in series, providing a nominal output of approximately 11.1 V (3.7 V × 3). This holder is ideal for robotics, embedded systems, DIY power packs and other electronics projects where a higher voltage battery bank is required.

Key Features:

• Holds 3 × 18650 lithium‑ion cells in series.
• Nominal output voltage: ~11.1 V, full charge up to ~12.6 V.
• Made with durable ABS plastic shell and spring‑mounted metal contacts for secure cell retention.
• Includes wire leads for easy connection into your circuit (typical 6″ / ~15 cm length).
• Mounting holes included for panel or chassis attachment.

Applications:

• Battery packs for robotics and automation systems
• DIY power banks and portable energy storage modules
• Arduino/ESP32 based embedded electronics requiring ~11 V supply
• RC vehicles, drones and model power supply (3‑cell series architecture)
• Educational electronics kits and projects
