4 x 18650 Cell box, Without Cover

The 4 x 18650 Cell box is an open battery holder without a cover that holds four 18650 lithium-ion cells. The cells sit between spring contacts and can be taken out for charging, so you can build a rechargeable pack for robot cars, motor drivers, LED lighting and portable projects without spot-welding cells together.

What's in the Box

• 1 × 4-slot 18650 battery holder (batteries not included)

Tip: Measure the output with a multimeter before connecting your circuit to confirm the wiring and polarity of the holder. Use four cells of the same type and charge level, insert each one with its flat (negative) end against the spring, and add a 4S BMS board for a safer lithium-ion pack.
