3 x 18650 Cell Box, Without Cover

The 3 x 18650 Cell Box is an open battery holder without a cover that holds three 18650 lithium-ion cells. The cells sit in the holder and can be taken out for charging in an external charger, so you can build a rechargeable battery pack for robot cars, portable projects and DIY power supplies without spot-welding cells together.

3 x 18650 Cell Box Applications

• Powering 4WD robot cars and motor drivers such as the L298N
• Portable Arduino and ESP32 projects, together with a voltage regulator
• DIY 12 V LED lighting
• Rechargeable battery packs for testing and bench work
• STEM and robotics classes

What's in the Box

• 1 × 3 × 18650 battery holder (batteries not included)

Tip: Before connecting your circuit, measure the output with a multimeter to confirm the wiring and polarity of the holder. Insert each cell with its + end matching the marking in the holder, use cells of the same type and charge level, and add a BMS protection board for a safer Li-ion pack.
