BB Extended Cup in the Future?

[datacreek]

I'm itching to pull the trigger and buy one but I have a few concerns.

Even though I'm fine at 3.7 I would like the versatility to try 5/6. Will the version currently available allow me to use higher rated batteries? I know they say not to use CR2s and I would be glad to wait until protected CR2s are available but I've heard the new ones are being machined not to take CR2s. So will the units available now take any other batteries that would give me options? If CR2s still fit I have no problem waiting for the protected but would they even fit
If not, and only works with 14500 will an extended cup be available in the future to allow use of different size/strength batteries?
I really like the size of the BB but would like the option to vary voltage or a greater maH battery.

EDIT: I guess a better question would be... if I were to buy a BB now would I have the option to buy the extended battery cup for protected CR2s to use with my device? Would it fit and would it be for sale?

Thanks

I'm Curious about this too. (As i just bought and received mine last week)

I got some of the protected cr2s & they're a bit longer for sure. They fit in the original BB but wont allow it to screw all the way closed. I'm hesitant to go full-fledged for any 6V protected-cr2 action till I hear its acceptable & I'm obviously not going with the unprotecteds. Any advice?

why not machine a small spacer to slip down over the threads at the base ?

how much area is exposed with the 2 batts installed i dont see why a spacer wont work so long as there is enough threads between the two original parts or the body

Where did you get the protected CR2's? Are they 3volt, or 3.2? Also, if it is really close, maybe a smaller spring in the .... cap may let them fit?

Not cost efective, the cost would be close to the same as the longer bottom.

yeah but a small spacer could be carried or worn like a ring vs a complete bottom the spacer is so much smaller anyhow you are the machinist doing the cutting
btw i own 2 bb's working on a 3rd and 2 Sb's you do have some great skill
thanks for a great product !!!!

I got some of the protected CR2 batteries last night and they do not fit the BB. Too long. I can use them, however, the top will not screw completely down.

You must have some small fingers, I may look into doing that as well. We shall see

not really small fingers it will ne like a NY pinky ring lol

first off i dont own a BB or SB so i dont know how you make them. i haven't grabbed one yet.

as i was a machinist for a few years... i ran a hass vf2 and a manual lathe ... spaces should not be that hard... turn the od to size (made quicker by correct material selection), drill a hole (or use tubing and bored to size), part 10 off - rinse repeat. if you use aluminum or another easy to machine metal and a bar feed lathe (or even a manual lathe with a collete that repeats within .001 to .002) you could have 1000 of these in a day.

not trying to rain on your parade.... but i've had to make Crap tons of these kind of spacers/washers.

also if the tool is right you'll get a minimal amount of burr left on the spacer when it drops. and if you're a high production shop you already have a vibrating deburring machine (man i wish we had one of those at the shop when i was there... lol)

i'm 99.9% positive a CNC lathe setup correctly could make a simple spacer Much faster than anything cup shaped with threads on/in it. as that would require even more tool changes, more cuts and more time.

just my $2/100

Forgot one vital step monk, have to cut two sets of threads in the spacer.

ahh if you feel that is necessary then okay... if a special washer wont work then... it wont work... i thought i read that it just wont screw down "all the way" as in it starts but doesn't bottom out on the threads... if you're talking extending inches, yeah -no- lol

would be nice if there were another *small* 5v mod out there... something not box shaped or grenade shaped. i have ideas on how to make mods drop to 5v but they're not something i talk about in open forums.
