in a flashlight that uses 4 123cr's can you just put 2 of these in line with each other???

If you gave a specific model for the flashlight, I'm sure we could answer this question better. The answer, given the limited information given, is "maybe". There are a couple things to consider. First, CR123s are narrower than 18650. CR123 are 17mm wide (diameter), and 18650s are usually a little over 18mm wide (diameter). So a light that is sized exactly for CR123 will NOT fit 18650. Many lights are sized large enough to accommodate both types, though, so it MIGHT work. The second consideration is voltage. CR123s are 3V, and they maintain that voltage right up until they are almost dead. 4 CR123, then, will deliver 12V for the whole of the battery life (not exactly, but close enough for our purposes.) Two 18650s will deliver only 8.4V, even when fully charged and under light load. If you ask for high current, the voltage will sag even more. And as lithium ion rechargeables are used, the voltage declines. At 50% capacity, they will be down to somewhere between 3.6-3.7 volts each, or 7.2-7.4 volts total. The question is, then, can the driver in the light compensate for the lower voltage of the 18650s, or not? Some lights can, and others can't, but without knowing the exact light you have, there is no way to be sure.

I'm not totally sure but if the four 123er's are in line then two 18650 in line should work. I would test and check to see that they are not overheating. Try searching on Google too.

All my flashlights only uses two cr123's but if yours uses 4 theoretically you should be able to stack them as most flashlights that are cr123 are designed to run 18650's as well. Good luck.

I believe so. My Fenix lights use either 2, cr123 or 1, 18650. One thing to note is that cr123s's are 3V, and 18650's are 3.7V, not sure if your light is able to run on higher voltage?

No it cannot. It is not a complete flashlight on it's own. Half of the battery housing is moulded into the assembly.

So you can use 2 or 4. Using 4 they alternate pulse from each of the 2 leads. It works pretty good!

Both the red and the blue did run 1/8 inch shorter than my factory brinkman flashlight battery 18650. But the spring connection in the negative end of flashlight took up the slack. If your negative end of what you are putting it in has a spring you shouldnt have problem. If it has a tab connection you can bend it forward slightly an be fine. Never hurts to try. They make these replacement batteries smaller for a reason. Little smaller fits all. Too big fits none. They will probably fit 90% of applications.

There are 4 groups available ABC&D, and you can pick any or all of them. In addition there are 4 channels available 123&4. You have to fire all groups(abc&d) on the same channel(123or4), but if you had a second set of strobes on a different channel, then you could use the 4 groups to fire them as well. It has way more flexibility than you can afford to have strobes.

Ah! So you are saying that if charging 1,2, 3 or 4 batteries, it is best to place one in each channel - NO in pairs. Thank you for the clarification.

I don't think so. There are many kinds of this flashlight in the all have different names on them. I think they just print the name on it. But it works, and its cheap

Hey, it uses cr123's (2) . 18650s are just slightly too big to fit in the tube. It's a pretty good flashlight ; however, I gave mine to my brother. For pretty much the same price the Fenix PD32 UE or PD35 are vastly superior lights in lumen capacity, function and user interface, as well as build quality.

If your talking about an individual bulb (PR6 for example) then no, I don't think it will work for you. This is an assembly that has the bulb and reflector assembled together as a single unit. I used it as a replacement for a SureFire tactical flashlight but it would not have worked in my 2 'D' cell MagLight. Hope this helps.

I'm an avid flashlight collector. Any flashlight that runs off the 123A platform will infact run off of the batteries in question. Be sure to buy the charger, and enjoy!

Yes. To be clear, they are designed to work together. The idea is that you get a flashlight with a momentary on/off switch on the back, then mount the flashlight just in front of the sling loop mount. Then you can momentarily activate the flashlight by nudging the sling loop mount forward.

Yes, you can! We have 4 and they worked great all together. You use 4 the same way you use 2....you have to aim each remote at each other and hit 'reset'...making sure all 4 light up and make reset noise.

It's hard to say if any batteries make one flashlight more than another. Less expensive batteries make flashlights end sooner than higher-level batteries. I would always suggest using the best batteries you can to make any flashlights go longer. Certainly the LED lights make a much stronger beam of light.If you are looking at the kind of LED Flashlight that I think you, you will be glad you got it.

I have this light and can use one, two or three of the 26650 batteries in it. The flashlight handle unscrews in two locations along the handle. Hope this helps.

Be careful!!! I bought a flashlight pressure switch combo from these people and they two items were not meant for each other. So needless to say, they are both worthless for my application.

Third yes! If it works with one set of batteries, and the other set is equivalent to it (if it works interchangeably in other lights) then the flashlight doesn't care what it is, it will run it the same. :) (if it fits in the tube, of course)

This flashlight takes the CR123. It DOESN'T fit an 18650. And the reflector is smooth, it's NOT and orange peel reflector. I have this flashlight so I can see all this in person. Lol. It's a great lil flashlight though.
