Efest 18650 2600mAh ft (Black)



Official specifications:

  • Brand: Efest
  • Min Capacity:2500 mAh
  • Typical Capacity:2600 mAh
  • Nominal Voltage: 3.7V




This is a unprotected 2600mAh cell with a Efest wrapper on.










The cells does track very nicely.











15A is way to much for these cells, but they do handle it without any problems.





Conclusion

These batteries works as expected.
At the current time I can only rate them acceptable, because Efest is a new company, and the batteries is not from one of the big brands.

Is this made from a Sanyo cell? It kind of looks like it from the picture.

Efest has not specified anything, if they had specified Sanyo I would have given them a higher rating.
But it probably is Sanyo (At least this batch):
