Note
1. This 18650 has built-in protection circuit and is designed for flashlights only.
2. It is a button top battery with total length 68mm. It will be too long for electronic devices that can only fit flat top 18650s .
3. The discharging current is around 5-6 A. It should not be used in flashlights that require 8A or more discharge current (usually it is stated in the flashlight manual or product page).
