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

Springs are a big deal. Did you see the ones Imalent used on their DT70 and DT35? Instead of coil springs they used disc springs which only flex a tiny bit, less than 1 mm. So obviously they want you to use the Imalent batteries. Even then, some of the batteries will lose contact. Springs have to be done propery. Lol

Ha ha.

I do know a lot about springs from designing suspension systems on race cars. Some of that knowledge transfers to flashlights like preload and usable travel, etcā€¦ I just try to state facts without any emotion, but maybe it seemed I was ā€œoverzealousā€ maybe? Iā€™m sorry, Iā€™ll try to tone it down. :sunglasses:

Sir Jason of Houstington, I salute your efforts to keep old springs lively and supple. Itā€™s quite unfortunate when springs enter old age and canā€™t perform like they used toā€¦

Itā€™s just ā€¦ I think the Q8 team has it covered. And as we wait for that to get worked out, why not play? The Q8 may not be shipping yet, but we can still ā€œshipā€ other fun thingsā€¦ so I used, as examples, whatever recent posts stood out. Not specifically trying to pick on anyone, but if it came off that way please let me know so I can be more careful.

On the bright side, youā€™ve officially levelled up to One Millihelen. Not many people have had a ship launched in their honor.

Because we are already a bit offtopic and i have to find something to do until the Q8 is out i want to ask if someone had experience with one of this UV leds?

I want to build a light with an MC-E led but the MELD-X RGBW (uv) flashlight driver has a 5 channel for a uv led so i want to get a nice strong 385nm led (for glue curing). If there is something better or stronger out there that did not cost 3times the money i am open for suggestions.

365nm is best for curing NOA.

JasonVW, shipmaster :smiley:

Weā€™re just waiting around til the batch is done perking.

And when itā€™s done, then the tasting starts.

Hereā€™s a topic worth discussing. Weā€™ve covered the light, weā€™ve covered the batteries, what about a good charger that has 4 slots and can do 1A each (4A total).

I was looking for one that can do 4 x 26650 at 1A each. I know xtar has a dragon plus that can do it, but itā€™s $90. There are the 4 and 8 bay Gyrfalcons that can do it at $30 and $55, but they are kind of tricky to use. Thatā€™s all I could find. Any other suggestions?

A $15 imax B6 will charge at up to 5A and works great, although the cell holder to go with it costs another $3 or so. Still less then $20 for a charger capable of charging them at 1.25A each if budget is the goal.

Otherwise I am not aware of any pre-made chargers that would work for cheap.

Have you got a link to that T_A? Thanks in advance. :slight_smile:

This one is a bit more then I spent but I am sure you can look around and find one a bit cheaper if you wanted:

Takes a bit more know how then just jamming the cell into the slot but it is cheap and very effective. If you flash new firmware it gets even better.

Thatā€™s a pretty weird unit. I donā€™t think I would buy that.

So thereā€™s only 3 chargers that can do 4 26650 at 1A each? I was hoping I missed one or two models.

It is the most common and most used hobby charger ever if I had to guess. It is just not setup with a cell holder, so you would have to get that separately.

Cheap, good, easy. Pick 2.

This is cheap and good but takes a bit more work to use. If you want it good and easy you will have to pay for that convenience.

On the plus side it can charge almost anything, I have used it to charge cell phone batteries, car batteries, Drill battery packs and UPS backup batteries among other things.

Hmm 4 x 26650, the cheap and good Liitokala lii500 wonā€™t do that, just two, it does 4 x 18650 though

More on charger wiring setups at: balance charging 18650's / 26650's

yeah, I google a question and it leads me right back to a thread at BLF.

That thread is talking about balance charging the cells, this is not needed if you charge them in parallel and parallel is much faster then balance charging in series.

Simply get a cell holder that is wired in parallel, hook it up and set the current and let it run. No need to bother with anything else. I charge 14 cells at a time like this and they come out perfectly balanced everytime.

Where do you find one of those for, say, four 18650s?

You can find them on ebay or aliexpress pre-wired or bare. I just got bares ones and wired them up myself but if you canā€™t solder then you can get the pre-wired ones. The wires are usually a bit thin though.

Iā€™ve been wanting a reason to use my rc charger for 18650s, now I have a reason, thanks.

I just hate how slow my nitecore d2 charges. Takes several hours for a single 18650. I can charge 3 5000mah 2s lipos in that time with balancing.

ok, I searched Google for:

ā€œ4x 18650ā€ battery holder

and found this:
