I have been getting 25500 Joules on a Yihi 350J @ 0.06Ohm Ni200 they have been much better than authentic Samsung 25R 20K Js and Hot HE4s 19.5K Js

Been using them since 29th April

Sounds like they've been working well for you!

I know that efest has a reputation for inflating numbers. Why they rate this cell any higher than 30A is beyond me though. Its performance plummets above that. Looking at a 3.0V cutoff, as that's about as low as anyone goes...
30A = 2000mAh capacity.
35A = 1250mAh capacity, a huge drop indicating that the cell is being used way above its capabilities.
40A = 400mAh capacity, 'nuff said.

But, I guess they wouldn't keep on doing this kind of rating if it didn't result in sales.

Note: when vaping we're not doing truly continuous discharges and we'll get better capacity than the continuous discharge numbers indicate.

Thanks for the chart!
I assume this was tested when new?

eFests have always held up for us.
I personally have 6 in rotation each being charged 2x a day for the last 8+ months.
20, 30 and 35A

Yeah a flashlight may see continuous, but not many mods, haha
