I am new to the game so this maybe a dumb question. My understanding is that manufacturers test cells at the factory and provide test reports to the resellers. If that's true, are these test reports available online? I've received two orders from different vendors; one from SFK and another one from 18650batterystore. The cels from SFK came with a label attached to each cell with some test results while the cells from 18650batterystore came nice and clean
