2 x 18650 Cell Box, Without Cover

The 2 x 18650 Cell Box is an open battery holder, without a cover, that holds two 18650 lithium-ion cells. The cells sit between spring contacts, which makes them easy to swap out or remove for charging, so it is a popular way to power robot cars, Arduino projects and portable devices from rechargeable cells.

2 x 18650 Cell Box Specifications

• Capacity: 2 × 18650 cells
• Cell size: 18650 format, about 18 mm diameter and 65 mm long
• Cell type: 3.7 V nominal lithium-ion (cells not included)
• Design: open frame, without cover

2 x 18650 Cell Box Applications

• Powering robot cars with L298N or L293D motor drivers
• Portable Arduino and ESP32 projects, through a suitable regulator
• DIY battery packs together with a BMS protection board
• Flashlights, fans and LED projects
• STEM and robotics classes

What's in the Box

• 1 × 2-slot 18650 battery holder (cells not included)

Tip: Most 2-cell holders connect the cells in series, giving about 7.4 V nominal and 8.4 V when fully charged; measure the output with a multimeter before connecting your circuit. Use protected cells or a BMS board, and insert each cell with its flat (negative) end against the spring.
