    New DOT regulations on transporting Lithium Batteries:

    Hi Ya'll- Pardon me if this has already been discussed, I didn't see it with a quick search. I just thought I'd pop in and give you the heads up on the new DOT regulations on shipping lithium batteries into and around the US...

    Coleman Max Cree, 3xAAA, 85 lm

    Re: Coleman Max Cree at walmart Just thought I'd check in and let y'all know that the 115 lumen 3AAA Coleman Max is on clearance at Walmart for $8.00. (Not the multi color... they are still $25). First time I've even seen them at all, and they are on clearance... . I may not check in here at...

    Bitter pill for owners of lights with proprietary LiONs?

    Kind of odd, given what people are saying lately around here about the short lifespan of Lithium Ion batteries, yet I have many 'ancient' LiIon batteries that still work fine. I have several things still operating with some 20500 LiIOns that were already in the surplus channels when I bought...

    Is this 18650 safe to use?

    Another one of those situations of : "If you have to ask the question; err on the side of safety. Get rid of it. (in a safe and ecologically responsible manner)". I might use it. No way I'd recommend anyone who felt the need to ask the question to use it.

    please help me, i am about to explode!

    1) All RCR123 charger can charge 3.0 & 3.6V? NO: Some will do both types if you flip a switch. Most will only do one or the other, although Kaidomain sells an add on circuit that will convert a 3.6 to do 3.0. There may be a few that adjust automatically, but they are uncommon and more...

    Build your own CD battery tab welder for $100

    Nearly burned a hole through the 'can' on the negative end, then when I tried tabbing the positive end, it pretty much burned the whole 'nipple' off, and probably even melted the safety valve shut, or opened it up completely..... I didn't want to look too close to find out for sure. Probably...

    Build your own CD battery tab welder for $100

    Yes, I experimented with that too. It does work, sort of, but not something I would use for 'serious' battery pack assembly, especially with smaller NiMH or any kind of Lithiums. 5.5-6v secondary with 6 or 8ga wire seems the best for battery work, but still not what I'd call GOOD. I...

    Build your own CD battery tab welder for $100

    Hi Gang. Long time no see; I kind of lost interest in flashlights and the like so I haven't had anything worth posting about here at CPF. But I've recently been working on a something that several of you might be interested in building for yourselves. Lately I've gotten interested in...

    I just bought a battery pack welder

    I built one about 17 years ago, used a big bank (about 3-4 farad or so, at 25 or 40 V (if I remember correctly)), of surplus power supply grade electrolytic caps in parallel. A mechanical momentary switch, even a massive one won't handle that kind of current without welding itself shut. You...

    Metal Gear Mod (Lots of pictures)

    I'll be darned... I've modded half a dozen Metal Gears to use Luxeon IIIs and 18650s (with custom heat sinks--- I do have a mini-lathe) in the last year or two , and it NEVER dawned on me to try to take apart the end-cap/ switch. Thanks for the hint. I'll try that when I get a chance to do...

    14500 3.0v Interest Thread

    I'd be in for at least four of the 3.0V 14500 LiIons. Eight, twelve or sixteen if the price is right.

    LED Stars with on board drivers

    I like the guy that runs the shop, bought quite a bit of stuff from him last year, and expect to order more from him in the near future. His prices are good and some of the stuff is decent to excellent quality for the price. Got one of these to play with. Let's just say I was less impressed...

    Avoiding 3AA & 3AAA Lights

    I kind of like the form factor of the 3AAA lights, and have bought several, mostly Garritys and Dorcys. Both are good quality for the price, and considering what I do to them, that is significant: Every one has been converted to use an 18650 LI Ion. (I don't even like using AAA batteries in...

    Just won a 238 led light. Who wants to touch me? (added photo)

    Re: Just won a 238 led light. Who wants to touch me? Nichia CSs cost 85 cents each in quantities of 100 (they are actually up five bucks per hundred from the last time I bought them). Back when I had the flashlight mod supply shop, I re-sold them for $1.15 individually or a dollar each for...
