Vapcell 21700 4500mAh 20A Rechargeable Li-Ion red???

Has anybody seen any testing on this cell or possibly know what’s under the wrapper?

Probably (almost) identical to Lishen LS21700SF, which is also available under the ShockLi brand with a 4550mAh 22A continuous current label (the differences in the label does not mean an actual performance/capacity difference between them).
