Based on these two tests here on BLF earlier this year, I picked up a couple and they’ve been good cells. Reality: +/- 10A (9.6A according to the secret datasheet that LP obtained) so if you want more then it’s back to 40T or Molicel. I have no complaints with these and generally I think their previous 4000mAh cells were pretty good, too. I usually run 50E or 40T but the Sofirn cells are certainly keepers.
