HUH... LOL.
That's the kinda crap that makes me chuckle. That the Sony and Efest 30A/1600 can handle more that the Samsung is ludicrous. We need tests, not some made up manufacturer's ratings.
BTW, here's some.
This was from Sun Vapers 20A Torture Test. He was comparing the Efest 30A to the Sony (looks like the Efest is just a re-wrapped Sony).
Ignore the upswept temperature traces the blue arrows are pointing to the discharge traces. The first thing to note is rather extreme initial voltage drop off at the beginning, at only only 2/3rds of Sony's claimed 30A, these batteries are struggling. The vertical line I added is when it hits 3.2V. Kinda hard to see but it falls at just a tad more than between 0.147 and 0.294Ah (0.220). I'll call it 250mAh. Lets look how the Samsung does at the same 20A continuous drain.
Right off the bat we see no major voltage drop, instead a smooth and gradual drop. Not a struggle like the Sony. I also marked when it hit 3.2V. Looks like about 1.13Ah = 1130mAh or 4.5 times more that the underwhelming Sony/Efest. Also note that the Samsung trace is a test of 2 batteries superimposed, that it looks like one is a testament to first rate manufacturing and QC. Who is making the Sonys? UltraFire?
How about a 30A test there are a few cells that can handle that. Here's one.
Again note the smooth and gradual voltage voltage drop of the yellow trace, no crazy hit like the Sony/Efest at 20A. Also note when it drops to 3.2V. Looks like about 500mAh, or double what the Sony did. And this is at a drain that is 50% more amps that the Sony was. OUCH!
I also see that the chart says the Efest IMR18350 has higher mAh/amps, and can handle lower ohms than the AW.
I could only only get a 3A test comparing the two.
First, we see a consistently higher voltage and more mAh with the AW. Note that the AW exceeds it's mAh rating (700mAh) coming in at about 720mAh. The Efest on the other hand doesn't come close to it's so called 800mAh claim. I'll take the chart's so-called lower rated AW any day.
Seems Samsung has a newer battery, unfortunately the vendor is price gouging a bit charging ~ 60% more that the 20Rs.

I ordered a pair.
