I bought this exact discharger which got a good review from one of the battery and electronics experts on this forum
It’s 5Ah, this test is accurate:
They are the exact same cells I have.
I still haven’t received my discharger yet but I have a new hobby charger which discharged the cells down to 3v and got 4600mAh at 2A which is in line with the test linked above, so I’m confident their numbers are correct.
I build mainly flashlights and remote control vehicles.
The improvement is at most a few percent, not anywhere near 10-20 unfortunately.
Hopefully in the future they can get closer to the theoretical 300wh/kg
