UltraFire BRC18650 3000mAh (Red-white)

Official specifications:

This is the unprotected version of the "3000mAh" Ultrafire battery, as usual the capacity is lower than specified.

The cell works fine up to 3A, with 5A is has problems.

Conclusion

The cell has an acceptable performance for cheap battery, but be avare that the UltraFire brand is made by more than one factory, i.e. the same label can hide a different performance, if bought from another source.

Notes and links

The battery was supplied by lightscastle for a review.

Long time ago I tested the protected version, it was worse.
