Cycle life: 300 cycles to 70% at 1A charge and 5A discharge, 2.5V cut-off.
This is high capacity cells that can deliver a decent amount of current, but are not high current cells.
The discharge curves tracks nicely, capacity may look at bit low, but that may be because I do not discharge to 2V. They easily matches the 5A rated capacity.
Conclusion
Very good high capacity batteries from a big brand.
Notes and links
Vapcell told me that I was missing some cells in my comparator and they would be happy to supply them.
I guess it is safe to say its major competitors are the MJ1 and “GA”. At 7A the MJ1 and VC7 are basically identical in voltage sag and capacity. The VC7 has slightly less voltage sag in the beginning.
The GA has slightly more voltage sag than the VC7 in the beginning, recovers and is then slightly better until the end and also has a little more capacity.
I would say GA’S are the better battery of the Three. I use them in several of my modded lights that do not require high, high drains like VTC5A/VTC5D/30Q!
Samsung has among the best available li-ion cell technology nowadays, and its pricing is fair. Sony is expensive. Just an opinion, of course.
By the way, king of high discharge 18650s is… the Samsung INR18650-20S. And then there's the Samsung INR18650-24S and the INR18650-25S. At this moment, Samsung is ripping Sony a new one. Period.
