Shockli 21700 4550mAh (Purple) 2018
- Nominal voltage: 3.7V
- Nomimal capacity: 4550mAh

High capacity and high current in the new 21700 format from Shockli.
The two batteries are matching very fine and can handle up to 20A. They cannot deliver full capacity to 2.8V, but maybe to a lower voltage.
The batteries gets fairly warm at 20A
And I had to stop at 30A
The batteries has lot of capacity and can deliver fairly high current, it looks like good batteries.
