Q8, PMS SEND TO THOSE WITH ISSUES BLF soda can light

The flat top 30Q’s that I had worked in my 2 Q8’s even before I soldered some 14 gauge wire (bent into a small circle) to the top of them. The only reason I added the wires was that I was concerned that the wrapping would be ripped off the top of the batteries when the body was screwed down. Solder blobs work just as well but I like the look of the wires so that’s what I always add to the flat top’s to raise them.

I made a diffuser out of a sauce bottle. After you cut the top off is is a push fit. Big W and Spotlight carry these in Australia. I also put a small convex blind spot

mirror in the bottom to block light from going straight out the end, and reflect it downwards and outwards.

Mr Excitement. lol cool

NICE! :crown: :+1:

Got any paranormal activities there? Ghosts like to suck the life out of batteries

"We call it “battery drain.” Prior to an investigation, we always check our batteries to make sure they’re fully charged. Sometimes though, we’ll discover that our new batteries become instantly drained the minute we walk into a haunted establishment.

Many enthusiasts feel this is a ghost’s way of powering up. They will drain the batteries, and sometimes even the energy of the investigators themselves, in order to communicate or manifest. After living in a haunted house for 13 years, I can tell you that there is some validity to this theory."

Hhmm. Might have triggered a safety cutoff. Think I heard/read even unprotected cells have some built-in safety circuitry. You might be able to "wake it up" by applying some juice to it - cheaper chargers can do it as well. Same way we can wake up a dead protected cell when the low voltage of the PC trips.

Hahahhahahahahahhahahahaha insane Tom , really funny :smiley: :smiley: :smiley:

Sorry for repeating myself, but what should I do with faulty Q8? ( Q8, PMS SEND TO THOSE WITH ISSUES BLF soda can light - #16508 by FreeMagenta )? Should I go to Banggood or ask Q8 Team? :slight_smile:

Hmm… The Miller had been handling support issues, which gives us significantly better results than a random tier-one support agent who doesn’t know much about the product… but he has been too busy lately so I’m not sure. Is anyone else in the project able to help?

Darn it. I somehow missed the release of the Q8's. I was in for two?

What is it doing, or not doing?

I’ve done more tests with my protected NCR18650Bs (from LiitoKala official store/AliExpress) — I only did in 2 samples though, so I’m not sure if there might be a difference.
It appears to turn on (at least for several seconds — not shutting down — I didn’t test for longer periods of time) at up to 5.70A. Then when reaching 6.1A it shuts off. So it appears the protection circuit trips somewhere between 5.70A-6.10A — is this an OK value?)

Made a video here using the Astrolux S41S (quad-Nichia) as test subject, and my 18650s on hand (I freshly charged all the 18650s prior to the test to get highest current draw on Turbo mode; although my test setup isn’t that good…):

It appears the S41S 4xNichia can draw over 11 or 12A with a freshly charged INR18650-30Q (at least the first few seconds, fresh from charger)…

Around how much current does the BLF Q8’s 4x XP-L HD drain at Turbo mode? (Does 4xNichia219 [not sure if Astrolux S41S s 219B or 219C] drain more than 4xXP-L?)

D_t_a, those batteries should be fine for the Q8 if you use all 4. The Q8 pulls about 15 to 16 amps total. So each cell only needs to provide 4 amps.

Button light sometimes flicker and fade. Though for now it works good for 24 hours… Possibly only on voltage ~4,2? Will check it.
Rarely there is a delay between button press and mode switching.

Both are on the movies in post in quote.

I have 4 protected Panasonic 18650Bs I bought from Banggood last year that I ran for hours in my 2 Q8’s without issues. But of course there’s no way to tell which protection circuit is in them.

Yeah, buying protected cells from Banggood may or may not have the correct specs on them. They are a big company and carry many versions of batteries. You’d just have to physically test them out like D_T_A did.

About the only way to get guaranteed specs on protected cells is to buy from certain stores like Mtn Elec, IMR batteries, Liion Wholesale, Illumn and a few more. They are very choosy about the cells they buy and sale.

On the video of the delayed button pressing, is that light set to ramping or mode sets?

The switch lights look like the common issue a lot of early versions had.

Do you have any soldering ability?

I’m really not sure what to recommend. Usually we would ask The Miller, but he is not around right now. I think Texas Ace is a Q8 team member. Have you tried emailing him and posting the link to your videos? I’d try that first and take it from there.

@FreeMagenta:
It sounds like a switchboard thing, and if you can unsolder and solder wires there are two solutions:
*wait for The Miller, he may have some arrangement with Thorfire for a replacement board (I don’t know what the status is of that)
*unsolder the board and send it (as a letter in a simple enevelope with a stamp) to me (=within EU) for repair,I could even get you a different colour leds if you like.

If you can not solder I’m afraid you will have to wait for what The Miller can or can not do for you.
