[size=+3]Sony US18650VC7 3400mAh (Green)[/size]
Official specifications:
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.
[size=+3]Conclusion[/size]
Very good high capacity batteries from a big brand.
[size=+3]Notes and links[/size]
Vapcell told me that I was missing some cells in my comparator and they would be happy to supply them.
