Conclusion

High current cells has increased significantly in capacity during the last year and this cell is the highest capacity I have seen to date. I cannot match some of the ultra high current cells, but it does very good at 10A (I believe that Keeppower has been a bit optimistic in their marking of the cell).

I will call it a good cell.
