The 4S 18650 Battery Holder is designed to securely house four standard 18650 lithium‑ion cells connected in series, providing an approximate nominal voltage of 14.8 V (3.7 V × 4) for DIY battery packs, robotics applications, and power supply systems. Its robust housing and series wiring make it ideal for projects requiring higher voltage battery banks.

Key Features:

• Holds four (4) x 18650 lithium‑ion cells in series (4S configuration)
• Compact size: approx. 80 mm × 76 mm × 19 mm (as per typical holder)
• Presoldered leads or PCB mount holes for secure attachment
• Suitable for constructing 14.8 V battery packs (when fully charged approx. 16.8 V)
• Standard 18650 cell compatibility (length ~65mm, diameter ~18mm)
• Made of durable nylon or plastic housing, mounted with screws or tape for stable installation

Applications:

• Battery packs for robotics and automation systems
• DIY power banks and portable energy storage modules
• Embedded electronics and Arduino/ESP projects requiring higher voltage
• RC vehicles, drones and model power supply (4‑cell series architecture)
• Educational projects and experimentation with lithium‑ion cells

Specifications (Typical):

• Holder Type: 4‑S (series) battery holder for 18650 cells
• Battery Type Supported: Standard 18650 Li‑ion cells
• Nominal Pack Voltage: ~14.8 V (3.7 V ×4)
• Full Charge Voltage: ~16.8 V (4.2 V ×4)
• Dimensions: approx. 80 mm × 76 mm × 19‑20 mm or similar size depending on model
• Mounting Holes: Typically 2 screw holes for secure fixture
• Note: For best performance, pair matched 18650 cells and use proper Battery Management System (BMS) when constructing packs.

Package Includes:

• 1 × 4S 18650 Battery Holder
