This is supposed to be a high current 18350 battery, it might not be perfect in that regard, but it has a lot of capacity.

The battery can deliver 5A, but not 10A. I wonder about the different in the two lowest current traces, there is a capacity different, but that difference disappears in the 0.5A to 5A range.

[SIZE=+3]Conclusion[/SIZE]

The battery has a good capacity and can deliver a lot of current, but being unprotected and with small differences in capacity it is best not to use it them series.
