Just got my Rayfoss 200mW laser

I was told for US, anything above 5mW will be taken by customs. I know some people lost 10mW lasers imported from china.

I find it cool with my green 200mw, how when you slowly open the aperture, you can make a faded dot..and the more you open it the brighter it gets...I can make it dim like a 1mw, bright as my 10mw, or full. Fun :) Also, If you look in the laser experiment/mod area you can see my build for the PHR.

I got my SoShine 2800mAh batteries today, the end is a tad wider too..So it grips in my laser but i can still get it out by holding the laser pointing up, and shaking it a tad.

Sadly, it leaves a 2mm space on my laser. This shows the spring is made to fit unprotected batteries. To fix this, I plan to buy a rubber washer to just protect it.

Are you sure that doesn't hurt the laser? I was thinking about trying it, but then I thought it might have a similar effect to turning on your BR with the dust cap on (diffuse reflection from the shutter).

That's cool, do you have a DMM to test? Most of the Chinese brands turn out underspec, so I'd be interested in those if they work. :)

Nope..how much do they cost usually...Do you mean the battery mAh power or laser brightness. I know the battery takes a bit longer to charge than my 2400mAh.

when did you order from rayfoss? I put in an order and it said it was delivered to my town the 9th and i havent gotten it. I just checked tonight so hopefully i can find something outin the morning.

I meant the battery current.

gloryofblaze: Mine took 7 days.
 
its fine..thats just the max it can output...just because its a 2800mAh doesnt make any difference. My origional 10mw laser batterys where 100mAh crappy china made, so I now have 1200mAh AAA batteries. Just because the mAh is higher doesnt mean it will damage the laser. ALL it means is you can run (if you really want) 1.2 Amps for 1 hour on it, because it can hold a charge longer (thus why they cost more) as a 100mAh, can only do 100mA for a hour until it dies. So going from a 2400 to a 2800, just means i can expect it to last a tad longer. 4.2V is 4.2V. Laser decides how many amps to draw. You can easily draw 30Amps from a battery, just expect it to die in a matter of seconds. Drawing that much however would require a circuit, not a short :P
 
I'm not sure if you understood the question... I know how the battery effects the laser, I was just wondering, can you confirm that the battery actually outputs 2800mAh, by it self? I asked this not because of the laser, but because I need some 2800mAh cells for my directly driven P7 light.
 
RL, you will not get that kind of discharge rates from ____fire cells. From name-brands, probably if they are new, maybe if they are used.

If you can find LiMn instead of LiCo, those are nice.

Also, if you have the coin, some 18650 A123 cells would definitely be able to supply that. I don't know if there is such a beast as an 18650 one, i know they come in like, C and D cell sized. They can spit out near 50A :evil:

But yeah, if you want performance, get some name-brands. The newer, the better. I have some panasonic cells that outperform my sanyos, probably because they are newer. I also have some Sony greens 18650gr, and I never use them because they are very old and don't work as well.
 
How can I test? Amping across the terminals is just a solid short that damages the battery. I will say in terms of charging, after converting some numbers it sounds just about right. These arnt ..Crappy.. ____fire cells. I dont waste money on cheap products.

Comparing to my old ultrafires, after using it a looot today, and volt meter it, it shows how much the ultrafires SUCK. I didnt even drop a volt and I used it on/off a lot during a 4 hour period...My ultrafires, I got it to 4V (from 4.2V) a looot quicker.

Yeah I was going to say on ebay they are 20 dollars (they have a US-located store in Florida) and deals extremes its 17 dollars...So i figured, obviously, the more you pay you'd expect quality. And these things also have temp. controllers..

SOSHINE 18650 PROTECTED Li-ion 2x 2800mAh Battery USA - eBay (item 330418430833 end time Apr-27-10 09:30:23 PDT)

However...This scares me, for your use. In normal terms, this function is GREAT against possible explosions.

"Function of over current: during the discharge process of battery : once discharge current gets over the set over current protection point, output cuts off to ensure battery works within the safe limit of current."

It's true because i tested mine..by reading the amps of the battery, just the meter, to see how much it can pull..0.000 :P proves short-protection works...
black = 0.3A, red = A and green = 3A

Off Candlepower, Should tell you..they list the SoShine 2800mAh :D
The only one that beats it is that UltraFire BRC3000...and Tenergy.

That Rayfoss looks like a real decent laser. I sure would be thankful if all you pros out there would direct me on the best possible laser money can buy, green of course. There are just so many and I dont have the knowledge like you folks out there. Thanks alot and God bless.
 
Thanks Kevin I think I will go with optotronics although CNI looks intriguing. Take care and keep shining.
