Bought 2pcs about 2 months ago,but tested them few days ago(fool).
2 discharge cycles,just to be sure,but 1st-2nd discharge graphs are more-less identical.
The “green” one has almost ok capacity,but voltage drops faster than mnke datasheet says.Maybe old,rejected ect. mnke with high internal resistance.
The “red-blue” is absolutely terrible in every aspect,low capacity,high resistance,and pretty hot at just 5amps.Totally different cell,and not even close to mnke spec.
Send message to efest,no response,but what’s interesting,from today there are two mnke26650’s on efest(different weight)!
Since 45days from payment is past,and no response from efestbattery(but I’m sure they read the message!),I’ll probably never see my money.But I hope this will save your money.
I too would like a good source of some high quality IMRs. My big mag takes 7 MNKE cells and one of them has lost capacity. So I would like to get another set. The King Kongs you can find on FT are good but not at all.a replacement for IMRs. Maybe FT can get ahold of some good 26650 IMRs for us.
