Very good match between the two cells, capacity does also match with specification.

Conclusion

These cells has good performance for 2600mAh cells, with nearly constant capacity, but I doubt the IMR rating.
As usual with good unspecified cells, the rating can only be acceptable.



Notes and links

The batteries was supplied by Sibeile for review.

Does that 30g specification forecasts the future “Lipo inside“® batch of Sibeile?
Thank for all this work, but we all know what to expect now, would be more interesting to test some smaller cells or anonymously bought 18650 in a few months…

And the cell is Samsung according to the flat top shape and cell weight.

Many dealers has errors in their specifications.

I do have some more Sibeile reviews I have to publish and they are not bad batteries. The part about anonymously is probably a bit difficult for me.

The charge and discharge curves does match a Samsung ICR18650-26C
