This is a high current cell from 2012

The capacity is on the low side and the curves do not match, I wonder if it is due to the age of the cell.
It can still deliver 20A, but with some voltage sag.


For its time is was a nice tool battery.

Vapcell told me that I was missing some cells in my comparator and they would be happy to supply them.
