Thanks for such positive comments! Answering the questions: The battery lasts about 45-50 minutes at 100%, and about 2 hours at 50% (probably the electronics have higher efficiency with less current). The charging time is about 8 hours (the controller limits the charging current to not overload the USB charger). As for the thermal protection, the controller has a negative temperature coefficient (the current is reduced as the temperature rises). However, it was not needed, the housing is large enough to cool the LEDs without any problems. I think I could even apply more power
Li ion batteries can be easily charged with a current of 0.5c. And this is for any capacity 2 hours. It is enough to install a 5.5 or 5.2 connector there and charge it with a charger from a laptop, or any other 12-13v .. If the controller limits the current, then it is better to replace it, since there are a lot of them on aliexpress. I also wanted to make a powerful flashlight, but I ran into a problem in finding an LED, many well-known brands of flashlights have small but powerful diodes, and large and low-efficiency assemblies are on sale .. I wanted to do something like yours, but with an adjustable focus and lens, with a power of about 50w on the assembly 3s 5200mAh from a quadcopter, they give a high current and quickly charge, and with such a size of the case, 50w will cool quietly .. And what would certainly be possible to make the cooling fins of an even larger area, taking a cutter 1mm thick and making grooves 1mm apart ..
Your definitely a engineer,or have extensive electronic training and experience. Good job. We need you to label everything and every connection please. Thank you for the video! How to know which will raise the voltage etcetera

Beautiful design and really nice build quality! I love the design. Nothing wrong with good quality cob leds..... but if you do a bit of research and poke around ......look at some of the Cree XHP LEDs… Like the ones used in the convoy L6 and M3… I think you’ll be amazed at what you could do if you grouped a few of those together in a light like this. Wonderful craftsmanship! Keep it up!
Nominal voltage for a 3 cell lithium battery is 11.1v. To produce 30w of power takes 2.7 amps at that voltage. The cells he used were 3500mA/h, which if 100% efficient would give 1h17min, but realistically it'll be more like 1h due to wasted power in both the driver and step up converter. Lithium cells last a lot longer if you don't fully discharge so limiting it to 45min would be best. I think he should have doubled the number of cells, and instead of 50% have low power be more like 10-20% as it's still way brighter than you need for most situations. Still a great build though.
@@mihanovak2228 nah it’s not. And don’t pretend you could‘ve explained it this flawlessly! No need for spewing defamation just because someone else was better than you...
@@JPEight It is enough to install good batteries there and not worry about their resource, they are not so expensive, and it is not so difficult to replace them, 6 batteries in that case would not fit, but a ready-made battery for radio models would fit in there. Rights they are expensive, from - for the given current in 25c. And here this is not necessary ..
You are right about batteries being not that expensive, but I’d still rather they didn’t need replacing regularly. Obviously there’s not enough room for 6 but nobody forced him to use that length tube...
Besides the result, the best part is that nothing is glued to death, even the cells are covered with tape, could disassemble everything anytime, wouldn't make sense but it would be possible. Great work 👍
That's a beauty. Made from almost scratch from the barest parts, and so solid too. Loved the use of screws to fasten the parts, that's gotta be one solid package. I get that it's not a commercial product, only a toy made for fun, but if only it had any waterproofing and like a 5 or 10% mode, I'd want one of those. 🤩
Dude, you're doing great things! I really like this flashlight, if I could find the ready-made electrical components, I would make one too. Beautiful video! keep it like this 👍🏼❤️
Excellent ! Very nice job without unnecessary things. What I miss in stock production and you did here is separation of switches for mode selection and on-off. Well thought project, congrats !
"When you need to see something on the moon". I frickin' loved this, great vid. I also found myself chanting, "Anodize! Anodize! Anodize!" as soon as you made the first section :)
Brilliant. What a solid build! One thing though. You’re aware that DC-DC step up Converter with adj. Constant Current exist? Could have made your life a little easier, I guess.
Phantastic light, overbuilt and you certainly can run it very hard as the heatsinking is great and the electronics seem to be able to handle all the currents with ease - even heatsinking on the electronic components! The look of the light is great. Only one question: I did not see any waterproofing. Did u add glue at the seals or do you simply don't care about that feature?
Beyond brilliant! I have a really brilliant idea, but I don't have the assembly/developmental electronic knowledge that you have. Where are you based out of if I might ask?

It doesn't over heat at full power?
Wonderful job can you make one torch for me
Can u sell this Torch and Wat price u can sell??

Your skills and workmanship are really great...especially on the lathe, beautiful and professional finish makes it really great.

As flashlight reviewer this is pretty cool, It makes me want a lathe.
Beautiful work. It would be really cool with rubber grip tape too. Love this. I've spent more money than I care to admit on flashlights. Great build
Beautiful work. Might need a little "texture" on the tube for traction?
Knurling!
@@joshfoley8862 was thinking the exact same thing
A tennis handle wrap would look good on it (I think). 😅

This is the best make of video about this type of light on UA-cam. I saw many many yt DIY videos, but this is surprise for me how great this is.
I love seeing smart people in action.

From full charge how long does the battery last at half power and at full power?
Nominal voltage for a 3 cell lithium battery is 11.1v. To produce 30w of power takes 2.7 amps at that voltage. The cells he used were 3500mA/h, which if 100% efficient would give 1h17min, but realistically it'll be more like 1h due to wasted power in both the driver and step up converter.

Very nice looking light you are a true craftsman great skills my man
Impressive piece of art and engineering. Well done
Suuuuuuper Work. Fantastic. The best Torch ever seen.
That flashlight looks like a light saber!
Ooh marvellous, nice job and good instrument for darkness.....
Solid and rugged look awesome job 👍
Loved the way you use glass from watchmaking side,
Sometimes such attention to details make perfect match 👍👍👍
Nice looking good flashlight👌👌👌👌

Why dont you just search for what he mentioned on eBay?
Szukałem inspiracji miałem przełączyć ale jak zobaczyłem że wytaczasz głowice latarki to postanowiłem obejrzeć do końca ;)

Nice craftsmanship- a work of art! Why anyone would give this a thumbs down is beyond me.
One of the best torch 🔦, keep it up
Fantastic powerful flashlight you build 👍

Really liked, with all these equipments one can do anything. Beautiful, neat and clean work.
Awesome,mindblowing,fantastic,superb 👌👍
High Quality Engineering... Great Work.
The driver look like entirely passive with no dedicated IC? Can we have the schemarics for other projects? It migth fit a flood light project of mine
Excellent ! Very nice job without unnecessary things. What I miss in stock production and you did here is separation of switches for mode selection and on-off. Well thought project, congrats !
Excellent work sir

You are very talented. I made a flash light in trade school in the early eighties. It can’t compare. 😂
Beautiful job is that flashlight for sale

Excelente trabajo. Saludos desde argentina
What are you using for the etching solution? It was clear.
That was a really COOL build 👍👍
Very nice work.
