They are the same identical battery. They are all the PLB-55 under the wrapper. Here are the brands they are sold as:

Shockli 5500mah
Keeppower 5500mah and 6000mah
Vapcell 5500mah red and 5900mah purple
Orbtronic 5750mah

I had to recheck the max continuous output (from 4.2v down to 2.8v staying under the max rated temperature) of the PLB-55. I was thinking it was 15A, but it’s actually 20A. It can do 30A for about 8 minutes. It’s considered a high capacity cell and not high drain, but it’s a newer design than all the other 26650 cells on the market. Its newer chemistry gives it pretty impressive specs.

(BTW, the iJoy 4200mah can do 30A continuous)

I’ve got the Vapcell 5900mAh (violet wrap) but not the Vapcell 5500mAh (red wrap). I also have the Shockli 5500mAh.

Doing capacity testing and IR resistance testing (YR1030 IR tester), I would say they are the exact same cell (also tried weighing them with a small digital weighing scale with 0.1gam resolution and they weigh very similar)

So I would add that the Vapcell 5900mAh (violet wrap) is also the same cell as the Shockli 5500mAh, and thus likely the same PLB-55 cell internally.

Yes, I think that 5900 was an earlier version that Vapcell did. They rated it a bit too high just like Keeppower did so they lowered the capacity on later versions.

Here is a link on the Shockli 5500mah with a lot more duscussion.
