Collection: 3.7V 18650's

18650 cells, perfect for Arduino, IOT, remote sensor, power tools, robotics, and anything else that requires reliability and longevity matched with maximum capacity possible. Use our pure nickel strip to weld the flat top cells together. Or, if your application only needs a single cell, use the protected button top inside an 18650 holder for a clean and simple product with up to 5A protected supply.
