[size=+3]Keeppower IMR20700 4250mAh UH2042 (Black) 2017[/size]
Official specifications:
A high capacity cell in the new 20700 form factor.
The discharge curves tracks fine, the capacity is present at low load, but at higher loads the cell has a bit less capacity.
At 15A the cell gets rather warm.
At 20A it gets too hot and i had to stop.

This looks like a very good cell with good capacity for its size.
