I found this cells in cheap Whitenergy Premium laptop battety. Well, i do not use it now in powerwall but today i am testing it. When i will be done i will post results. ;)

OK, i tested 4 cells.
I read 2500mAh. It was tested at 1.2A and 0.6A discharging with the same results.
Tested mine and came out at 2600 - 2900, with most falling in at 2700 - 2800 mAh at 1A discharge in Opus BT-C3100 tester. I got them out of an ebike battery.
I think the"M" means medical. I only find these in medical packs and they have the same characteristics as the F model. Also, the spec sheet for these day for model F/FM
i found this:
  • Country of Origin: South Korea (F) or Malaysia (FM)
what do you think? can be fm the same as f, but made in malaysia?

today i am testing this cells again with new charger so i post new results soon.
