Sony US18650V 1600mAh (Green)
This is a older Sony cell with fairly low capacity by todays standard and moderate current handling.
The cell can deliver about 10A and capacity is fairly constant with load. The two cell has a very good match.
When this cell was new it was probably both high capacity and fairly high current in top quality, today it is not very impressive.

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