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 ..
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. 🤩
@@joshfoley8862 Knurling is certainly good .. but it’s cold to hold on to the metal .. and with gloves, it’s not going to slip out of your hands at all.
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.

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...

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 !
wow, i'm a flashaholic and at begining i wasn't liking the idea of that chunky flashlight. but it turned out soo good, oldschool and **functional** that i really liked it, it just works!, no stepdown, no fancy modes... it just works
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.

Excellent ! I am sure you have good experience on turning, fitting, engineering and electrical/electronics circuitry besides excellent workmanship ( the soldering skills shows it )give it a chance to make it mass produced, it will be a hit ! Best luck
that flashlight is cool. it's so big you could add a camera lens adapter to change focal length.(a telephoto lens could be a laser. thanks for the nicely done video.
Great job! This looks like it is super bright! The forest footage in the video reminds me of some of the paranormal investigations I've seen on youtube of so called haunted forests and such.
What a great flashlight. From an engineering point of view, it contained so many disciplines: lathe, pcb design and manufacture, choosing support components, CAD, system-level design, and so on. Great flashlight. What did the finished product weigh?
Very nice craftsmanship! Like the modularity! But U would add knurling and mayby elocution along the handle area and swap the USB micro B for a Type C port.

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??
@@ajiparayil2762 settle down samir
Your skills and workmanship are really great...especially on the lathe, beautiful and professional finish makes it really great.
The pleasure of seeing something you've made working well.
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
Really like that clean look! Nice job :D

As flashlight reviewer this is pretty cool, It makes me want a lathe.

I love it!! Awesome use of that COB LED!! Subscribed...
I love seeing smart people in action.
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.
IT'S A BEAUTIFUL WORK! Very well done and "clean". I saw a person who works perfectly!
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). 😅

You just blew my mind with that board you just made BY hand I’m not to electronics.. but that’s an instant subscribe. NICE
Loved the way you use glass from watchmaking side,
Sometimes such attention to details make perfect match 👍👍👍
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
Nice craftsmanship- a work of art! Why anyone would give this a thumbs down is beyond me.

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.

I could not make nor could I afford this beautiful flashlight.
Nice looking good flashlight👌👌👌👌
You are very talented. I made a flash light in trade school in the early eighties. It can’t compare. 😂
Woww...
That is so cool.. Also really bright.
Wow such amazing video
No time wasting frames
The custom PCB took this flashlight to a whole new level,
You should have coated the bare copper with nickel to prevent oxidation...
I am totally blown away on your video amazing to have such great talent to build something like this you're truly awesome
Most suitable flash light i have ever seen 🔥🔥
Awesome. Next project same light torch but with focusing and lens , two or tri levels of power, more batteries and raw gripping body.
Szukałem inspiracji miałem przełączyć ale jak zobaczyłem że wytaczasz głowice latarki to postanowiłem obejrzeć do końca ;)
