laser mod, thanks cisco - e-cigarette-forum.com • The place for electronic cigarette reviews, news and chat

a while back I saw a laser pen modified to be a battery, created by cisco. so I got a laser on ebay.

New Ultra Powerful Red Laser Pen Pointer Beam Light led - eBay (item 320431539847 end time Oct-09-09 16:27:40 PDT)...

I unsoldered a resistor that went to the diode (its still in there) and soldered a wire to the pcb and stuck a plug up the 901 batt thread. it was fairly easy, I had to shorten it so I could have one AAA battery reach both springs and make several drills (widening things for press fits or remaking holes). I used the pcb it came with and their button. not a very easygoing button to press, gotta press kinda hard sometimes, but it all works and gave me an excuse to use my 10440 500mAh 3.6V li-ion rechargable AAA batteries.

thanks again cisco!

Nice!
I'm waiting on my parts now... (Apparentlly, they still have to mine the ore to make the metal to make the parts.... ) :-(

I keep hearing about these batteries blowing up if overdischarged, is there protection circuitry built into the laser?

where do you keep hearing that?

it has a cut off at 4.2V and 2.75V respectively. though I dont think there's any protection on them. thanks for the warning: I forgot about that.

I rechecked and all my other batteries have protection (not AAA sized).

it's a snazy mod but I'm finding its not as good as the traditional 901 batt.

so I wont be using it too much, and especially after that reminder.

The biggest problem with them is a short circuit which protection doesn't help with, over-discharge would occur if you continued to use them long after the vapour had died out or the button was continually pressed by accident or by a fault in your construction. If it was in your pocket the heat from the atty would tell you about that.

About as close as I can come to answering that is basically on this forum, usually in the modders forums. I suck at referencing. Some things stick in my head, probably badly, and this is one of them. There's one veteran modder (again, can't remember who), that is very vocal on the subject of unprotected batts.

I personally don't worry to much about it, there is no alternative except to have a custom batch made up (then they become to big to use), I always find it funny that we're willing to suck down gallons of juice from unregulated factorys in china, but scared sh##less with an unprotected battery. Safety tip from your vaping buddy tdstrike-"when the gizmo stops making vapor, stop pushing the button" and here's another one- "if you're going to put a device in your pocket, twist the atty a quarter turn"

You get that a lot here, I have numerous mods, only one uses protected batteries. Its more a matter of how you build the device with 3.7v..now with 6v, you definately can run a battery down to dangerous levels..but with 3.7 vapor is long long gone before you reach 2.7 recommended recharge threshold...in fact at 3v you barely get a wisp of vapor at all.

If you're still interested, you can check out this thread for some recent discussion about this The ABCs of batteries or you could check out the battery mods forum and posts from Mogur, Breakfastchef and Cisco, all seem to be pretty adamant that you have to be very concerned about unprotected batteries. While it might be (surely is) true that vapor production goes way south as the battery drains, many noobs just keep pushing that button trying to figure out what's wrong.
