“REVIEW”: DQG Slim Ti (1/2 AA and other batteries) ***[DISCOUNT CODE ADDED - 05/22/2018]***

Hello Merlin :smiley:
Eheh, thanks for your comments above and for the tips for the mods!
I am a bit bored with this, but I guess I will back to it again, as you said! Damaging the tailswitch was also a minus , but I “reinvented” it and made it simple and easy now, so I’m ok with it!

But the driver/LED… I also thought about that: put a filled down MCPCB above the shelf’s hole, or use a 14mm aluminium PCB with XPL-HI or XP-G2 above a sheet of copper or brass, drill some holes for the wires and put the driver below the pill.

First I have to take it out (didn’t manage to do that so far, that is tightly screwed in), then check the space for the driver (has to be single sided). I guess that if I can take the pill out, the rest will be less troublesome :smiley:

I forgot to mention: tube’s inner diameter is around 14.7mm . So a 15mm driver will need some filling as well :person_facepalming:

These are indeed tiny lights, very dense and compact! But it’s a matter of perseverance! But they could be easier to mod :weary:
Eheh

Thanks again for the tips CRX :+1:

(I will be looking for your mod of this :smiling_imp: )

Thanks pc_light :slight_smile:

Indeed, the tail construction caused some destruction on the attempt to reach the switch, but it was so compact that I never noticed that there was that double thread tube :person_facepalming:

Applying some rotating force to it might have helped to unscrew it and remove the plastic safely…but it didn’t happen.
I too soldered a thinner spring on the bottom of the switch, but with the plastic that damaged, I had no means to make it stay in place again, hence my solution with a Convoy switch. Fortunately it worked, otherwise I would have a +30€ flashlight damaged :smiley: :person_facepalming:

I tried to count the seconds and on the 3rd, I guess that the effect disappeared. But yup, on fast ON > OFF situations it may be annoying! So I will give it some time and will probably get back to this light later to check what can be done concerning the driver and LED!

If or when I get to unscrew the pill, I will post some photos of that and let you know how it went! I will try not to be a destroyer on that as well :smiley:

As you, I’ll stick to mine like this for a while ! BTW the “pebbled” TIR lens gives it a nice beam, maybe not so “throwy” , but a nice floody beam! :+1:

Thanks for your comments and word on this :wink: Enjoy the light!!!

AH!!! One question: how do you charge the 14250 cells ? :expressionless:

Here’s the driver unit from the DQG AA to give you an idea what this might be like.

To get the aluminium threaded section out without damaging the threads I ended up cutting in two slots for leverage of a small bar as it was well glued, heated it first.

I mostly use the Opus on 200mA for charging my 300mAh 14250 cells but have a couple low current modded TP boards too.

Hum, my guess is that they will be exactly the same.
Below the driver there is a sort of “protective” black foam, but the driver seems to have those kind of chips in the bottom. And the top seems to be exactly the same thing!

Hum, thats is very “magic” :nerd_face: With those grooves it becomes easier to rotate it! Nice!! I may pick that tip to try the same on mine!

I won’t provably use 14250s (despite the “small” version is cute), but I was curious. I don’t know if my BT-C3100 is capable of doing that. I’ll check the distance!!

Thanks CRX, again :sunglasses:

Great review. As we had discussed awhile ago, I bought the same light which arrived DOA. It was all involving the tailswitch. With very little help from DQG or the vendor, I got it to come on but it was very erratic and would only come on about half the time. I thought it had good potential but got so frustrated with the light, vendor and DQG that I sold it off for parts.
Anyway, thanks for the review and hopefully you can enjoy yours.

Hi Venice!!!
Thanks for stepping in :wink: Yup, indeed you were the first person that told me about the switch issues! Well… I thought it would be easier to solve them back then… Clearly they are not! :person_facepalming:
But I guess that has to do with the position of the spring, a slight rotation on that might stop the flashlight to work normally! If I had mine back then I would have been a better help for you…

I remember seing your sale thread ! I couldn’t buy it by that time so I ended up ordering this one!

I hope you found a light that works without issues and I hope that DQG can improve these lights :wink:

:+1:

Moved on to the Vollsion SP11 but have issues with it also.
The best (most fun) new light now is the AceBeam UC15. Love it, built like a tank and it works as advertised!!!
Not sure about claimed output but looks very close to my 18650s and 18350s.
I really wanted the DQG to work out but it was not to be.

I use a spring spacer to help charger contacts reach.

Thanks for all the info on this light, I’ve looked at it from time to time and just couldn’t figure out the stock battery configuration.
The listing says “1 x AA/14500/14250/ 2x AA battery (not included)” and the size and shape of the light just didn’t support the 1xAA part.
If the little “1/2” was a snake it would’ve bit me.
If ordered it comes with 14250 support, anything else requires an additional extension… I think.
The 14250 is a little off the beaten path so it seems like this would be a great candidate for a built-in charger.
Thanks for the review and all of the comments!

Bansuri, correct it comes ready to run a single 14250 cell. And the extension tube (in a similar variety of metals as body) must be purchased separately.

Each extension adds 25.0mm, the equivalent length of 1/2 of an AA. Thus 1x extension permits the use of a full 14500 cell or even a single AA. Presumably the addition of 3x extensions would allow the use of 2xAA, since the driver is capable of 4.2V.

Nice light that one (Vollsion)! Small and pretty :wink: I guess I’m not a twisty fan, but that seems nice, despite the issues you faced :frowning:
I hope the Acebeam gives you a nice option for EDC, small and bright again :wink:

Oh, ok! Nice way to make it work :wink: I went through other way, but it’s nice to know that you managed to make it work well!!

Thanks bansuri!! :wink:

I don’t know if you’ve seen it but CRX turned his DQG Tiny AA to use a built-in charger :wink:
I will only use this as AA or 14500 light probably! If I really need it to be longer or have longer runtimes, I’ll pick 2 more tubes :wink:

Like you say, 3 tubes give the possibility to use 2 AA batteries (not 14500s) ! :wink:
Giving the small size of the flashlight, even with 3 tubes it will probably still be small :smiley:

Hey folks!

Thanks MascaratumB, ordered a brassy one!

Nothing to thank to me friend :wink: Let us know what you think when you got it!!
I’ll probably get one of those later! But I still wanna mod mine first to see what expects me :wink:

That was quick! My last 2 orders from the East arrived in about a week, wonder what has changed?
Anyway, what a cute little light. It was hard for me to get a feel for the size because the pictures really look like a CR123-sized light but I knew the size was about the same as a AA battery.

PKCell ICR14250s on the way, I’ve got some 1/2AA at work pulled for annual maintenance but still usable. We can’t use them anymore but I’m too frugal to throw them away. Can’t wait to try it out!

Here are some size reference pics.

That was a really fast shipping! Nice!!
And the brass is sweet as well! :blush:
Hum, how will you charge the batteries? I didn’t bought any 14250 because I have not way to charge those :person_facepalming:
Did you bough the extension tube as well for AA/14500 version? :wink:

I ordered the AA extension a few days later, hopefully it arrives as quickly.
My Nitecore D4 has a 300mA charge rate available so that should be OK with the 14250s I ordered.
We’ll have to see what niche this little beauty fills. The Sanyo UR14500P claims 840mAh so it may be hard to pass up nearly 3x runtime for smaller size.

Looks like there’s more to come for DQG:
(from the website)

Slim AA (1425014500) is on doing.

A Key ring quick-release UV light kit with Tritium location function (still on designing).

A head light use CR123A/16340/17335/AA/14500 with L SHAPE, also it will be smallest one in the world. (after sampled several years ago, still on designing)

A thrower flashlight with as small as possible in size up to 3000+ lumens output in high. (on planning)

Nice petite, but a little expensive, light.
How will it do on a CR2A primary (½AA sized non rechargeable 3 Volts lithium) battery?

I didn’t try it on those batteries, not even on the 14250, as I don’t have none! I believe the behaviour in terms of output will be somehow in the middle of AA and 14500s.
But can’t be sure :zipper_mouth_face:
This is a nice flashlight, despite it’s price! I would use it more if I have the smaller batteries … :weary:

You don’t use Lithium primaries for high output, because they can’t deliver the current, voltage will sag dramatically.
You should use it with a boost driver (like you would with 2x AAA)

The nice thing about primaries is that they will keep their charge for some 8 years or so, and they have relatively high capacity (mAh)
Perfect for glove box, kitchen drawer or purse lights that you don’t use often.
CR2 lights are rare. CR123A lights are more common.

Not sure if there are any *R*CR2 (rechargeable, higher current) batteries available.
Probably, but maybe not with exiting specs…

(EDIT)Hmm… Just read that CR2 are 15270 size. 1mm wider and 2mm taller than 14250.
