Samsung INR21700-50G 5000mAh (Green)
Samsung high capacity 21700 cells
The two cells tracks perfectly, they handle 15A nicely. It looks like they must be drained fairly low to get full capacity.
They may handle 15A nicely, but they do get rather warm doing it.
The batteries looks good with lot of capacity and are fairly good at delivering current.
