Imren has two different 3000mAh cells, both high current.

The discharge curves looks good, nearly constant capacity and very good tracking between the cells.
I had to stop early on the high current discharges to avoid melting my test station.

At 30A the temperature increases very fast, I terminated the discharge after 2 minutes and 30 seconds.

Conclusion
The cells looks good, but they cannot deliver 30A continious.

The battery was supplied by Imren for a review.
This test is run on my updated equipment and is not directly comparable to the other Imren 3000mAh test.
