The discharge curves are very good, then match nearly perfectly and capacity do not vary much with load, even at 30A

Conclusion
With the low capacity is is probably a fairly old generation of tool cells, but high current performance is very good
Notes and links
Vapcell told me that I was missing some cells in my comparator and they would be happy to supply them.
