These nameless cells that only carry the name of the company that owns the wrapper can be replaced by whatever the company wants later on, change cells as they wish to since there is no claim to any particular industrial cell name (brand and model).
The graphs at high current match HE2. At 0.2A the curve is identical with the HE2 expect for the first short part, but I guess that can easily be due to manufacturing batches. At 10A and 15A the Shockli seems to not be as good as the HE2, the 2 Shockli cells don't track identically.
The positive pole screams of Samsung. In any case, like with all other high availability, unprotected high-drain 18650 IMR rewraps, I don’t know what value Shockli’s rewrap actually brings to the table, and the Samsungs are dirt-cheap already.
