OK, this is an XY problem:
What you really need are rechargeable AA batteries that can work at temperatures not much below freezing. For that, you have lots of options, but the best is probably AA Eneloop NiMH batteries. I recommend you get these ones (make sure your battery specifications match the packaging in this photo):
Get this package first to get the highest quality charger on the market:
You need that charger to get the full life out of Eneloops. If you take care of them, Eneloops will last at least a decade, maybe longer.
Another good option are Tenavolts rechargeable lithium AA batteries:
Those will have the higher voltage the Blink expects. Your energy density requirement seems to be a wild goose chase, since it's eliminates all your options, even when most of those options would work well. You can have cutting edge technology, or you can have stuff that just works. The Blink camera is in the category of stuff that just works.
If you ended up doing a massive 18650 project, you might be disappointed to find out they're no longer cutting edge technology. That goal post has moved to 21700 batteries:
You can change your battery type frequently to keep up, or you can stick with something reliable and proven. You can still have cutting edge performance, but it will be in things like longevity (Eneloop) or an all-around combination of reliability, capacity, and temperature extremes (Energizer Ultimate Lithium).
In the end, the choice to use AA isn't all about capacity. Just like with cameras, it's not all about megapixels. Or with cars, it's not all about speed. Or with aircraft, it's not all about altitude. Etc. If you want to stay on the cutting edge, it's could be horrendously expensive, and it still won't get you to the grocery store any faster.
AA Eneloop NiMH batteries have an excellent temperature range, almost as good as AA Energizer Ultimate Lithium batteries. If those will work in the Blink camera (I haven't tried it), that's what I would personally use. If it didn't work, I would try Tenavolts next. If that didn't work, and I was adamant about not using disposable batteries, then I would consider other alternatives, but not before trying the easy ones first.
I personally would not choose 18650 for a low power application. 18650's excel at high power applications, while AA batteries excel at low power applications. The biggest advantage 18650 has over AA is literally being bigger. It's a bit less than 3 times the size of AA for a bit more than 3 times the energy of AA. So, if you need a lot of power in a small space, 18650 (or 21700 now) might be the better choice, but that's not the case here.
The cells are going to be re-wraps of something random. See the Q/A section of https://www.amazon.com/ask/questions/asin/B00ME3ZH7C/5
The original rating is 12000mah, which makes the original cell capacity 2000mah each. It's also listed as 3A mac discharge current. I see no way to tell if that limit is in the controller or the cells themselves.
Also, the cells appear to be in a weird 2p3s layout, but I can't tell by the pictures.
Note - these are likely connected by spot welded metal straps. Getting them separated can be a challenge, and getting new cells in place will require more spot welding or soldering, as I don't see any spring loaded contacts to allow easy replacement.
IMHO, use the power bank as-is. When it stops doing what you want it to do, toss it in a Home Depot or Lowes batery recycling box.
It's a bit special, but uses an 18650 and could be made to run on any 18650 pretty easily.

This guy says he's 18650 but I haven't heard of the company before (they sell them at Sears though): http://kaitoradio.com/ka500lyellow.html
For a full-featured radio, the Tecsun shortwave runs on 1x18650, no NOAA specifically, but it'll do am/fm.

Ahh ok I see where I'm getting confused now. So for my situation I will need a 29.4v 2A 7s Li Ion battery charger? Would this one here work?
Or does this not have the CC-CV you're talking about? Thanks!

I have not but read the comments ppl have tested it to 20A. You'd need like 4pcs per battery from this 360 pack:

Hm. How easy would it be to retrofit that for a stock 18650, or mod the 326263 so that the 18650 was removable, I wonder?
Front light is a Convoy S2 slipped into a piece of inner tube to protect it from banging against the handlebars, then attached to the handlebars with a broccoli elastic. (I'll replace the inner tube and elastic with one of these silicone straps at some point.)
Rear light is a Nightcore HC50, with the headband replaced with a velcro cable tie that wraps around the seat post.
Maybe if they are bad quality. Good ones pretty much never wear out. Even assuming they wear out, gram-for-gram a spare pizeo sparker will outlast an 18650. Though the peak for weight/longevity would probably be the UST Micro Sparkwheel.

It's nuts how powerful it is. I tried an 80w from MicroCenter (he biggest gun style they had) and it BARELY did the job on some test cells. I have an ancient US version of this one I just tossed a new tip and cord on.
