With our revolutionary new technology called "lying" we can make our cells do anything at all.
150A discharge? Not a problem!
Technology is called “not being classic Li-Ion chemistry” in case of thing I linked to, not “lying” 
Sorry, I didn't see the link at the bottom of your post - my office is too brightly lit for pale grey tiny text to show up. I'm pretty sure those do - but not in an 18650 size.
But they do 5000 mAh and 250A continuous in just a bit over 18650 volume (pi*18265 = ~660 cm3), and BOATLOADS less than 26650 volume (almost half, in fact - pi262*65, 1400 cm3), being 810 cm3. 
Should be pi * r squared, not d squared. so is 3.14159 * (9*9) * 6.5 = 16.54cm3 or for a 26650 pi*1.3*1.3*6.5=34.51cm3
The HobbyKing pack is 9.32*4.7*1.85cm = 81.04cm3 - or about the same as 5 18650s.
Using 5 IMRs in parallel (same volume, though I suspect rather more weight and bulk) you should be easily capable of 100A - just not for very long. At best 40% of the capacity
Apologies for the pedantry - I used to teach this stuff.
Oh gee, I failed quite hard on that one. Shame on me 
Is this even possible?!
Those GTL brand they are claiming 2500mah on AAs or 14500s. So 5000mah doesn’t suprize me since it’s 2X the size? that store has 99.2% positive feedback and for it’s volume per month the negatives are pretty low. About 50 sad customers out of 2500 that’s pretty amazing. Funny how most of the complaints are CR123s, AA & AAAs.
100+ usd for 2 batteries ? :o
Nahhhh, more like 50 mah
LMAO!!! Now slap it on eBay and sell it for $50 with $250 in shipping.
Uh, you forgot Samsung, LG, and Sony. Their cells test at rated capacity as well, and are just as great in terms of quality and safety.
We can make our own 18650s. Let’s label them 50,000 mAh and really rake in the dough…uh, I mean Paypal disputes! lol
Wow. That seller has the lowest feedback I think I’ve seen.
Has anyone measured them?
1 Lumen equals 1.7604 Fake Chinese Lumens ( FCL) .
This has the correct sense, in that you need MORE FCLs to equal 1 real lumen, becasue the FCL is a small unit.
1 Fake Chinese Lumen = 0.568 Lumen
