This is a high current cell with fairly low capacity like all high current cells.










This cell is not really interesting for application with 1A or 5A current draw, even at 10A it is not that interesting, but above 10A this cell will still deliver current.
And as can be seen the ouput between the two cells has a very good match, even at 30A.





This cell can be safely drained in about 3 minutes. That is safe for the cell, it might not be safe for the load or connections (30A is a lot of current).











Conclusion

This is a very good cell, but only for special applications, i.e. where the current is in the two digits range.
