Windyfire 18650 2700mAh (Black)
- Nominal capacity: 2700mAh
- Nominal voltage: 3.7V
This battery is neither a high current or high capacity battery, but has a decent capacity.
Discharge curves has good tracking and the protection kicks in a bit above 5A.
The battery do not set any performance records, but if the price is right it looks like a good cell for low current applications (Like many flashlight).
