Some notices to DQG Tiny 26650 V3.0 (post by designer and producer: GEORGE)

thank you. I see now, at current, I don’t think there have copy of this light in the market, but the idea be stealen is much often and I also think it is nature rules (although personal feeling is unwilling), otherwise human cannot go developments. so, at current first I should question myself why have this problem, it cannot explain by forget gluing as I belive, now most possibility as you said maybe the glue is very little, but I can remember I does have do some testing of the glue force, or maybe my force is weak.
I am a short guy strongly loving small and powerful tools. :slight_smile:

For example in my current edc Skilhunt H03, used 16 * 2 magnet, tailcap thikness is 0.5mm, it can easily hold flashlight in horizontal position.
Overall space after battery end, is 2 + 0.5 = 2.5mm.
Maybe for shorter tube of the tiny 18650, could be used 1.5mm magnet. It would be 2mm thick tailcup with magnet.

Thanks for being here George !

I received mine some days ago , and i really like it . Thanks for this nice light , really looking forward for a 18650 with 4 leds .

Just reading this thread makes me want to be a future customer! Nice job George.

Hi George, really glad you came to BLF welcome,

I was going in circles with Alysonhe at Banggood regarding your lights here the 26650 and finally I suggested to Alysonhe to send you an invitation to come to BLF were you can get a better understanding of what some of the issues are.
So I got Alysonhe’s message last night that you are now here at BLF, so again real glad your here George.

I haven’t had time to read all the posts here but took a few pictures this morning to better help you understand what I see as an issue with the driver retainer mostly,

I not only bought one DQG but during conversations with Alysonhe I bought a second one to see if what I was thinking might be correct and I think it is,

The retainer’s are not only undersized but they are different sizes also, no consistency,

I see talk about glue, neither of mine are glued, well that is not accurate, when I got the first one this is how I found out about the retainer in the first place,
I thought I was unscrewing the tail cap but was actually unscrewing battery tube from the head then the head and the tube came apart and out dropped the retainer in my lap and the driver was hanging by it’s two wires,

I tried to remove the tail cap from the battery tube with my hands, but I had to use two rubber strap wrenches and some light flame to get that tail cap off,
I know it seems unbelievable but that tail cap was GLUED to the battery tube, I took a picture of what I saw but can’t find it just yet.

I figured out how to reassemble all of the driver, align switch, used a pencil to hold everything down and drop on the parts and then the tube, well got it working with the switch perfectly so I run up the light and it got fairly warm so I look in the optics and I see all this dirt in the optics so no big deal and went to clean it out,

I didn’t press down on the optics as I turned the unglued bezel I perfectly dedomed all 6 outside LEDs,

Anyhow, that’s it George, your assemblers should tell you that this retainer which I assume is supposed to be a press fit like it is in the 18650 which I also have and it is tight,
I have never even tried to remove the retainer in the 18650 because there’s not need to, switch on that light is OK,

You could possibly come up with a switch that has a longer nub sticking out towards the boot, with it attached to the board like that and with these 26650’s having off sized machining I have to make sure and push the driver towards the boot in order to make the switch work perfectly,

Here’s a picture of what I see and hope it makes since to you,
You can see that out of two 26650 the retainers are both different sizes, so that’s something with whoever is machining your retainers and there’s a picture of the gap between the retainer and the threaded wall,

Thanks for coming George, I personally love all of your products and if I can help I’d sure like to,
I am happy with my lights

Edit out garbage, but think I am still to long…

T18, no offense or anything, but George, with his limited english, may have a difficult time devouring your wall of text. Maybe not :slight_smile:

I agree, have been sort of stressing over it, and debating whether to cut some out, some things could have been left out.
I am most worried about DQG and this light in particular, something is really wrong, I have at least a dozen of their lights and close tolerances as always been obvious to me, so what happened here is odd?
But yes a wall of txt for sure, as usual, I’m long winded and extremely detailed to a fault, maybe I should just edit some. Thank you Robert, I do respect your opinion or advise, comment, got thru to me anyhow…

I think that’s a great attitude. :+1:
And it’s why China is probably going to ‘win the race’ of technical and industrial development very soon!
(Maybe they have already…)

It happened to Jaxman and by manufacturers and vendors that you’d never had suspected would do such a thing.

Yeah… As yishenger said: “although personal feeling is unwilling”, and in our culture it’s even illegal.
Somewhere in the middle would be best i.m.o.
In our culture developments are often slow because of patents…

Another fan of you!, from Spain very good flash lights, I have a spy and a v4 18650, I using every day!! thanks to go to the forum even with you english!! :slight_smile: mine is very bad too :slight_smile:

Yet, you find the time to author a post poorly disquised as helpful but negative.

You clearly expect George and others to read your post yet you do not extend the same courtesy to the other members. Why the double standard?

I encourage other members to look at T 18’s past posts and you will find that they are inherently negative and complaint filled. Feel free to review my history of posting as a comparison. No double standard here.

Why don’t you start your own company, since you clearly believe you have the expertise and from your posting- you have the time necessary .

You are constantly picking on people from other cultures, you have a habit of deleted many of your posts which were rude and crude. You are just a bully.

Hello George. love my DQG… is there any plan on putting different LED? maybe XHP 70? of course it will get hot very fast, but it sure is will be a good conversation piece;)

Maybe XHP35 HI on slightly longer head? :smiley:

Hey, hold on a second. I see no problem with the post from T18. It is critisism with positive reinforcement. This is a good way to offer the information in his post. And I think his observations are helpfull. There has been some questionable quality issues with this light, though they are minor, and I think I it is information that will be helpful to George.

Anyway, what was said is usefull information and it was offered as such. In my opinion anyhow…

Edit: ok, I see the post may have been edited by the time I read it. I did not read the origional post. So my comment is only in regard to the edited post and I may be too hard on boro.

Easy guys. I believe the post your talking about had been edited before you read it as T18 mentioned. Lets keep it nice and show yishenger what a terrific honest place we have here. :slight_smile:

Hi, T18, thank you very much for you post. here I can see my mistake of assembling now. before the glue is solid, I will check the light is work fine or not. if not work fine, I dispart it, slove the problem then assemble again, Obviously I make wrong side of the battery tube, becuase it is mirror design, so, the tailcap glued with the tube when glue is solid.
about the diameter of the cover ring, it does smaller than the host in design, to different size, its mechinical result, every size have its tolerance, such as +–0.1mm, the biggest can large smallest 0.2mm is accepted as common rule. but why tiny 18650’s ring not come out? because I use a little thermal glue on electric component will hot, but in these days, I find the thermal glue cannot do help: because before the glue solid, the ring cover is displaced already by tighten tube action; and wost, the thermal glue always will lead bad electric contact due to its leakage, so, at current 18650’s, the ring cover will drop out when dispart the battery tube.
and good find about the switch nob relationship to the rubber button, it will lead bad press action if they not contact each other. due to soldering shift of switch, PCB and host etc tolerance, there does will have this problem, it also why I try to dispart it and assemble it again, then displaced the battery tube.
very careful observation, thank you very much. and also should apologize to you about this mistake.

nice to meet you. I have an english dictionary!

Hi, Boro, don’t complain T18, I think he is a serious man, I like his detail post. maybe something he is not famillar.
about standards: in mechical field, there have many differant requirements, the tolerance are difference. highly Accuracy size should use very special designed device to manufacture in order to maintain same demmession. for light or other like products, usually don’t need so accuracy tolerance, otherwise nobody will Machining for me for so little quantity. but, I think accuracy is our goal in every field for every product if can and economic.

Hi, at current, I think only 7*XPG2 can make as small as could and power nearly reach XHP 70 (with refelctor or optics), XHP 35 HI suit for thrower, so, I now have no plan. maybe future designning tiny thrower will consider them.

Any chance of a 21700? I’d buy tomorrow. Literally.
