New Batteries, possible game changer?

They get a little hot at 15 amps, don't you think? Last thing I want are manufacturers changing the battery size
Slightly bigger than a normal 18650 (2mm wider and 5mm longer) with 25% more battery life at 10 or 15A than a LG HG2. Sounds good.
I doubt it would fit into a Reo @Petrus -
but if it did - then I would buy a few immediately!
I honestly doubt it's going to be a game changer. 18650 cells are way too common in the market and *most modern mods are designed to accommodate them exclusively. But it's nice to see some tinkering in this area. I think the game changer will be once someone can produce a cheaper battery which packs more punch (using some new breakthrough chemistry) in the same form factor
I agree with @The_Ice, the industry has invested too heavily in the 65mm battery form factor to ditch it now. I think we'll be using 18650s and 26650s for some time yet. Of course, mod makers could design a mod around the 20700 and then provide a battery sleeve like the Pico Mega does to accommodate an 18650. But I doubt it will become the norm. If anything, I'd see the industry moving towards batteries that are shorter than the current 65mm. Progress inevitably leads to things becoming smaller. A battery that is 5mm longer than the current one will surely not become the new norm.
I question the "more power for slight increase in size" statement. Per volume it seems like a decrease:

Great @Raindance !
So this battery is less efficient (capacity wise) for its size then
Not really packing much power in there after all
I wonder if mooch did those calcs
PS - i think your lengths should be 65mm and 70mm but your volume calcs look right to me
Thanks Silver, was wondering what to make for supper tonight, I see its going to be crow pie ...again.. Lol. Will correct that bit, thanks.

For interests sake I compared 26650 bats to 18650 as well. I think the larger volume impacts on heat dispersion and that may be a limiting factor in improving performance linear to volume growth. I'm no pro on this topic so don't take this as truth.

Very cool, thanks @Raindance I think your calcs are relevant. It's pure volume vs capacity. It shows that on a per mm^3 basis the 18650 is way ahead.
Hard to compare true capacity though because one could theoretically get a 6000mAh 26650 but at a max of possibly only 10Amps constant draw so its tricky to do a direct comparison in that sense.

Exactly, but 2*18650, say LG chokkies, are the same total mah at 20A so the comparison is made for those in the know
16A, ain't safe, the temperatures that thing was getting to, ain't safe neither.
