Yeah...no. You're grossly overstating the differences of vaping and flashlights and discounting knowledge that can be learned from battery enthusiasts that favor these cells no matter the hobby. Your thoughts are based in generalization and hearsay. Vapers test all different types of cells at a...
You've already said this, and I've already responded....the 30Q still shows less sag at 20A (and still has a far higher density to size ratio), although for lower outputs it's a fine/great choice. There are actually better 26650 cells out there, but they aren't as readily accessible (Brillipower...
New info - the new 2170 cells will have all new state-of-the-art hardware and new battery chemistry! It may even be able to match/beat 18650s in energy density ratio!
Zebralight's XHP35 powered lights put out (a likely underrated) 1300 lumens from a single 18650. The Wizard Pro v3 runs a XHP50 to 2150 lumen off a single 18650. The Nitecore TM03 (XHP70) puts out 2800lm on a single (albeit proprietary) 18650. Boost drivers will continue to improve so I don't...
Try any of the mutli-emitter flashlights that pull over 10A on FET (many pull much more than just 10A, closer to 18A in some cases). The Manker E14 comes like this, a production light and you won't get close to it's maximum output with a single 10A cell. It's also not necessarily about maximum...
That's the question. I guess they may have to test it to make sure the headlamp size/shape will dissipate heat adequately, but other than that I don't see any issues.
So using your theoretical reasoning, why not improve upon existing 26650 cells?
In fact, they did release the specs of the 20700 B cells and they didn't match the current GA cells...it only got to 92% of the energy density (4250 mah) with similar current discharge rates. The 20700 A cells give...
