It does not work like that.

Any unprotected 18650 should be fine.

Are you asking what battery gives the highest output?

How many batteries do you plan to use?

The usual suggestion is 4 × 30Q button top. High drains give the best output.

If you don’t care about highest output, you can run high capacity like 3500mah as well as protected cells.

@ JasonWW,  My self, im fine as i have a couple hundred 18650s to choose from VTC6,30Qs even some that put out a constant 35amps continuous unprotected, protected etc "but" my brother in Western Australia only has 18650s that he has taken out of old laptop battery packs & there flat tops,so he will have to solder blobs on the + end, Thats why i was wundering (to get full output) does he need 20 amp continuous from 30Qs or will protected 10 amps continuous do the job ? or would he be still getting full output with the old laptop batteries he takes out of laptop battery packs ??

 

Thanks...

Brett

Mismatched cells are safe to use due to them being in parallel, but it’s best to use a matched set.

With 4 batteries the most it should draw is maybe 16A so that is only 4A per battery.

You will never get the highest output using old laptop cells. You need high drain cells with the lowest resistance in order to get the highest output.

Right now 4 × 30Q button top batteries are on sale for $20. Not bad at all. I might grab an extra set for myself.

@ JasonWW,

 

 Yea maybe $20 USD for you for 4 x 30Qs on sale, "But" for me $28.20 Australian for 4 x 30Qs, A fair while back they were only $23 for 4 of them & so i bought about 32 of them & haven't seen them as cheep again since.  <img src= " /> <img src= " />

For us(we) Amazon US purchasers, I see only two reviews.  I know we all said thank you but I think Sofirn was hoping for a whole bunch of verified purchase reviews.  I wrote one of them.  I suppose anyone who received one is having fun all night (thanks to the high capacity) and sleeping all day!  tongue-out

I sound like a broken record, but 5775.3 lumens is what I get once again on a brand new just took it out of mailbox Sofirn Q8. Rested 30Q cells at 4.19V. Literally dropped in the cells and put it on the light box, first time I turned it on.

TK? I flashed Anduril on this new Q8 with the exact same result, no side switch back-light. Zero modification to the light other than flashing Anduril. And to be sure my file was clean I downloaded it fresh from your site and installed this new file. Under lockout condition, tap-tap-hold only gives me momentary moon level. No blinks or anything else. Testing functions shows Anduril working perfectly, as before.

Maybe y’all can help me on this, I will be modifying this second Q8 soon and the plan was to use SST-40’s for something in the range of 10,200 lumens. (Done it before) But I like doing things different, so now I am wondering if it would be worth it to use XHP-50.2’s and see if I can get 16,000 or more from this Q8. Am even entertaining the thought of building a top end extension fitted down into the Q8 head with cooling fins above the existing head to aid in heat management. Probably wider than the stock head at these new fins. Thinking to just use 4 pairs of 18350’s, run time would suck but it wouldn’t be used for long periods anyway… I already have the new MCPCB’s, SST-40’s are en-route, don’t have the 50.2’s. What say ye?

I would say just wait for the extension tube for the Q8.

You’ll get 8×18650 compatibility and the ability to draw massive power levels. And much higher capacities compared to 8×18350s.

Kawi , I had three in my scratch build that drew 21A at 13,000+ lumens, no poof!

The one in my Jaxman is making 3000 plus on two 14500’s. Think it’s at 3A or so in that light.

Djozz has tested them up to 15A.

But yeah, there’s that possibility which is why I asked. The Quad set up may make the difference, don’t know…

The Q8 ramping mode blinky settings has me confused. Double click to turbo, double click to strobe…then what ? I have tried single, double, and long presses and I can get it to change strobe types sometimes but not with any consistency, Also , it doesn’t memorize the change for next time. Should it remember the new strobe setting?

I don't think so. You do have to keep on clicking till you get to the Blinky you want.

you can’t dilly dally when in strobe, as soon as you enter it, you need to click to the strobe mode you want, single clicks, within 1 second or that mode will lock in….
unless you got a defective light but i have never heard that particular issue.
& no, it doesn’t save strobe settings.

Hard to tell which strobe mode you have switched to if you have to click within 1 second in order to keep switching.

Yep, it is. Thumbs Up . . To eliminate this problem just memorize/remember the number of clicks it takes to go to the strobe you want. That way you do not have to ‘see’ it to get there.

Just click to any blinky mode besides the first one.

It will lock in after 1.2 seconds. Press and hold and it will go back one blinky mode and unlock for 1.2 seconds, at which point you can go forward through all the modes. If you stop on the wrong one, press and hold to unlock again.

This is the same procedure for mode sets.

Blinky modes are not memorized.

Try this video, it’s not very good, but it shows the basics.

/\ ….. Thanks for that info Jason. . Thumbs Up . I didn’t realize that could be done. Of course I rarely use blinkies….. Wink
I have number of clicks to ‘beacon’ memorized & that’s it for me. Big Smile

I watched all your videos , Jason. They were very helpful.. I don’t use strobe much but I was just monkeying around with it and wanted to learn it. Thanks.

I got my Sofirn Q8 from AliExpress. It came with NarsilM v1.0, I have flashed it to Anduril (09-07-2018 hex).
My side switch button does light up, and can be configured to Off, Low, High or Blinking states.

I’m not sure I understand what you mean by no side-switch back-light? The side button totally does not light up green?
