- 18mm x 65mm cylindrical cell
- Integrated protection circuit
- Rechargeable via a TP4056-class module
- Button-top with protection adds a few mm to length
What you can build with the 18650 Lithium Cell with Protection Board
- Battery-powered ESP32 and LoRa nodes
- Solar-charged outdoor sensors
- Portable instruments and torches
