well i have grey wrapped 'protected' cells , and blue wrapped 'un-protected' cells for DX
Well so much for my theory.
well i have grey wrapped 'protected' cells , and blue wrapped 'un-protected' cells for DX
that's a major reason these things will be banned , having an unstable power source so close to the users face.
I wonder what kind off safeguards and standards mobile phones have with their batts.
Still , glad your all ok Eskimoroll. I'm guessing the failed battery was un-protected ?
and don't forget a protected batt will be a millimeter or two longer than the un-protected variety.
That's what I've wondered about with these factory e-cig batteries, non of them have protection circuits. I'm sorry, but it's rather annoying having to wait for it...wait for it... wait for it... "OK it's green, quick take it off the charger before it fries!" you know? I see the marketing aspect, people keep having to come back for more batteries about 4 per month sometimes, but come on...
I'd apologize for the caps, but I think too many people are disregarding safety in how they build their devices. These are not toys, the only electronic DIY I can think of with a higher danger factor is a hand-portable medical or industrial-grade laser. If they were running off of a thermite fuel cell, would you be so casual with them?
FYI -
VaprLife.com now sells 10440 (AAA) protected trustfire batts
The one you point to wouldn't be a good option, if you zoom in, notice that it was hand-soldered (and a +/- 1A/33% error margin?), although I was thinking more of the ones that people tear out of protected cells. The stick PCB's from the same store would be a better choice (won't let me link it because I'm a newbie here).Wow! Thanks for the wealth of info in this post. So since you know quite a bit about this, tell me:
If I were to use an unprotected AA size Li-ion 3.7v 750mAh battery like the 14500 in a mod. Could I use a PCB such as this one for device level protection? Do you know anything about the nuances, like how long the leads can be or what their minimum resistance must be to ensure the PCB cut-off functions correctly?
I've got a mod in mind that needs a standard AA size but would have room for a PCB separate from the battery. Though the PCB probably wouldn't be switched out whenever the battery finally gives up so it needs longevity.
Thanks Wiz, many want to minimize my thoughts and even mock me on this forum, which is extremely immature and obvious, but my vote goes towards safety first for everyone!
Does anyone know if the janty stick has a protection circuit? After reading this im a little nervous about using it :-S
Don't sweat it. The JSv2 has a device-level protection circuit. That is, protection is built into the Janty Stick.
