Are these CR2's protected?

[Incognito]

So I'm thinking of picking up a BB soon. I would like to have the option of using it at 6V(without hanging around a wall-plug) but really don't want to use unprotected batts. After searching for about an hour I found this site. They don't list any detailed specs but two things make me think it's protected. There is the tell-tale hump by the positive end, and you can just make out the words "The voltage of full charge and cut-off discharge is 3.6V and 2.0V". So protected or not? Also it says the length is 27mm, which I think would barley fit in the BB.

No the batteries shown are not protected.

Bummer I know madvapes and some UK supplier carries them but they are sold out. I've been looking through some old posts here and there was some talk about Altsmoke stocking them. Any news about that? Or does anyone know where to get them?

I thought the problem was that no one makes them at the moment. I think I heard that AW made them some time ago but isn't currently. The flashlight guys are looking for them too. ...then again that might have been a really old thread...

Electricity 101 question...

If you're drawing 2 amps at 6v and your power supply consists of 2 x 3v batteries. How much current is each battery supplying? (I'm guessing the answer isn't the one we're hoping for...)

Ya, I found a bunch of threads about the AW ones on various flashlight forums. Looks like they stopped making them a few years ago though.

As for the electricity question, I don't really have the knowledge to answer that. I'm guessing they each supply half though???

Electricity 101 bonus question:

I got one of those battery packs. Holds 4 AA batteries, has an on/off slider switch, and a usb connector labeled "5v". ... What's going to happen if I put 4 AA alkaline batteries in there and plug my BB passthru into it?

I've always thought the battery companies stop manufacturing them because the r123 is superior in every way except size. Even that is not a huge difference. I wonder if they will even bother again.

^^^If it's a cheap battery box it probably outputs 6V (1.5V x4). If it's a "classier" one it might have a 5V regulator built in.

And if I am using a 2.2ohm 510 atty is it just going to turn into a puddle of melted plastic? or do I have a viable, emergency backup power supply?

oh yea, cheap. about $4... can't get much cheaper than that It does come with a belt clip attached though.

I think it would work. Plus it would be convenient with that belt clip attachment I once powered a 510 atty with 4 C-cells, some wire, and some electrical tape just to see if I could
