SUREFIRE FURY + AW17670 : viable ?

:wave:Greetings from BELGIUM.

FURY + AW 17670 (1600mAh) rechargeables
Is this a safe combo ?
Safe for the torch ? (I don't intend to ruin my future flashlight, knowing that Surefires are very -very- expensive, here in Europe) .
Safe for the battery ?
Do you find it a « pleasant-usable» combo in real life ?

This specific topic has been discussed, from time to time, in the Fury general thread.
Nevertheless, your latest experiences and comments will be much appreciated.




:bow: PS. Please keep in mind that I'm French speaker. I do my best in English... Anyway, if you ever find an unpleasant way to understand my words, this would be unintentional. Thanks for your comprehension...

If the battery fits without forcing then yes it's safe to run it on a 17670 (I'm not sure that it does). Maximum discharge rate for regular li-ion is usually around 2C (3.2A for 1600mAh cell) so there are no problems using this battery with the fury.
The best option is to have it bored for an 18650 which would allow you to use a 3400mAh cell giving you over twice the capacity of the 17670. You must be able to unscrew the head from the body before someone will bore it though. Some fury's will unscrew with a lot of force but some just won't. You can also buy an aftermarket body that will take an 18650.

I didn't try a 17670 battery as I wanted to have my SureFire P2X Fury bored so I could use the 18650 rechargeable batteries, however I couldn't wait the months that it takes for those that offer the service to get enough customers together to make it worth their while.

I searched CPF and youtube and discovered that a member had bored a 6P using sand paper taped to a bar in a power drill.

I did the same, it took me an evening (which was longer than I expected) starting with 60 grade paper, it would have be quicker starting with 40 grade. I finished it off when the bore was large enough to accept my Nitecore 3100mAh battery with 400 and then 1200 grade Wet 'n' Dry paper, with a bit of washing up liquid in the water, to achieve a polished finish.

My surefire fury using 17670 for almost a year since i received my fury february last year,absolutely no problem.I using it as my bicycle headlamp to my buddy 's place every weekend and the 17670 provide enough power and runtime for my 1 hour trip (i mean the entire journey from my home to there and back to my home).

I´m using 17670 as well in my Fury. No problems although I don´t use it that much. And if the head on mine would give in I´d bore it for 18650 as well. Unfortunatelly it won´t budge, no matter what I throw at it.

I am happy to report no problems using single 17670's or 2 x rcr123's in my Fury.

In my fury I am using a 16650 battery.
It has 2200 mah and seem to function fine.
It feels great to not worry about spending money on 123a batteries.
All I need is darkness.............

I've also been using a AW 17670 in my Fury ever since I've owned it. I bought it new right when they came out, and I've not had the first problem. My advice is use the 17670 and save your money on buying batteries.

How does the capacity of the 17670 compare to (2) Surefire CR123a batteries?

Also, once you bore the tube for an 18650 can you still use (2) CR123a batteries?

I would highly recommend buying this!!! http://www.candlepowerforums.com/vb/showthread.php?371214-18650-urefire-Fury-body-By-FIVEMEGA

Looks great but that is about what I paid for my NC Cobra.

Okay, I found this that shows one brand of 17670 to be 1600 mah.

http://www.lighthound.com/AW-17670-Protected-Rechargeable-Lithium-Battery_p_101.html

And this CP thread lists the Surefire CR123a to be 1559 mah each (x2 = ~3200 mah?). Or is it just 1559 mah total since they are used in series?

I apologize if this is derailing this thread. I am just trying to understand why one would want to use a 17670 or 18650 instead of two CR123a in series (other than the obvious capability to re-charge).

That's just 1559 mah when in series, not doubled.

I'd agree with the poster that bored it himself with sandpaper. I've done it before as well, albeit with a different light. Just get a drill bit that's close to size as the tube, tape some < 100 grit sandpaper to it and wrap it around until it's almost snug in the tube, and go at it with a drill. It takes a while but gets the job done.

Besides the saving in not having to buy new CR123's if you change to a 18650 there is also a substantial increase in useability.

Thanks for all your comments, experiences and advice.
Very useful to help me make my decision.

How about the behaviour of the Fury when the 17670 comes to its end: sudden shut off or slow dimming to lower mode ?

Correct me if I'm wrong but i tot when batteries are in series or parallel, their voltage & current are affected but the charge of the batteries should be added up.

And I recommend trying to get the head off first. The head on my fury won´t budge a bit.

On runtime time between the two the Fury geta around ~40 minutes on a 17670, and on two CR123's you should get around ~1.5 hrs. of runtime. As far as using CR123a's in it after you have it bored, Oveready sell some delrin tubes so you can run a CR123a in a bored light. As far one for the Fury you may have to cut some of it off too get a perfect fit in the Fury, they are made for a SF 9P but with some modifications you can make it work. Here is a link to them.

Also here is a link to tell you everything you want to know about the Fury, I mean everything. It's a real good thread to read thru. It can answer about any question you have about it.

Check out that thread. You also need to consider 6V from two CR123a VS 4.2V (max) from a 17670/18650.

Do you notice a loss in output using these batteries? Sounds like RCR123a's might be a better choice?
