Not only for pop can blasters, this battery size is just about perfect for fitting in a lantern. That alone gives it plenty of appeal for the camping and outdoors market.
I was just coming here to post something similar. These would be awesome in LOW powered camp lights, weeks or months between charging..... and then recharge via solar. Same for use as a lower powered but wide dispersion SOS/Rescue application.
Of course the 46950 is going to have a much higher capacity than four 21700 cells. The larger the diameter, the higher the capacity increases exponentially. Every additional wrap of the jelly roll increases the length of that wrap even more. For example, a 2 inch diameter pipe has almost 4 times the volume of a 1 inch pipe.
@4:29 “so…a little bit below” @1A only 5.6% shy of rated @5A its 9.6% shy @10a its 14.4% below claimed. It is a large size & the capacity is “a little” smaller than it appears. 🤓
I think this battery has a future in special lights for police, army, fire department etc and for a few enthusiasts but for massive sale it's just too big and heavy and can't beat practical properties of 18650 and 21700. Of course I have one as a flashlight enthusiast 🥴 but for my explorations of abandoned places and my tramping I'll use one of my 18650 or 21700 flashlights.
I think the sales numbers for flashlights large enough to use these cells is extremely small in comparison to the rest of the market that needs to keep products small enough to be easily carried by people. The same applies to other battery powered devices, they either need the space, like laptops, or need higher power draw like in power tool batteries. I could see that making these cells very hard to get.
You make a good point, these won' be a go-to for smal devices. However the main industry that will be using these cells are EVs, which is likely to make them very common (unless another format takes over instead). Tesla has already manufactured 20 million cells according to an official post, we'll see if the format becomes widely available elsewhere.
Depends. Security guards, law enforcement, hunting, fishing, camping etc are all demanding high power portable lights. I always have my 16000 lumen flashlight in my car and it comes handy at numerous occasions.
Debatable. D cells were a standard long after smaller cells were developed. Security, law enforcement, Search & Rescue, camping and outdoors, all of these fields have plenty of demand for these chonky batteries.
@@ethan-lumencraft- okay well that’s interesting about Tesla. I am not well informed on exactly what has made other battery formats accessible to the masses and I didn’t know how much EVs using a certain cell contributed to them being available outside of that EV manufacture. I obviously have some doubts about this cell being widely available long term like 18650 and 21700 but time will tell, I love the idea of this cell for the crazy capacity so I do hope they catch on and become/stay available to the masses. I did buy the convoy L8 and a bunch of 26800 cells but I can still use a 21700, I guess the same would be possible for the Lumintop lights you showed. Someone could pretty easily create some type of carrier that could fit a 21700 inside of, at least they aren’t too short like 26650 cells. That’s the biggest thing I didn’t like about 26650, they were too short to be able to retrofit a 21700. Btw that Lumintop mach v2 is an absolutely beautiful light, I’d love to own it but at least for now I’ll regretfully be holding back. Lumintop has been one of my favorite manufacturers for a long time and I’m thrilled/appreciative to see them being so innovative and putting the time into making their lights look so absolutely stunning.
@@lumntoob999 Tesla is the entire reason why the 21700 cell exists. They essentially invented it. Then all these huge manufacturers adopted the technology and form factor. The same thing is happening with the 46950.
Good video! I ordered 1 mash - 46950 flashlight for a trial, I live in Siberia and walk in our large park for 3-4 hours at night. I already have a Q8 on 3- 21700 and MF01s on 4-18650. Progress in batteries is good and I support this trend of progress, in any case, good luck or not, this is a step into the future.
It's a bit chunky even for my long fingers. I find the 36650 / 36700 to be a near ideal diameter. Funny, because the old "D" primary cell was about a 34620.
Flashlights and li-ion batteries have gone a long way and approved a lot! I built myself a 100W Led flashlight of of 18 x 18650s in 9S2P config, giving me 1 hour of 100W light :-) More than enough for me...
$150+ flashlights are so niche, I don't know that these will become "common" due to the price and large form factor. Proprietary batteries are frustrating, it drives me nuts with Olight to the point where I always look for other options first. I do have the mini Marauder because on sale, the price/features/performance was great. But 32650 proprietary bugs me. Just realized that the numbers likely match the size... 18650 = 18mm diameter 650mm length... I feel dumb for never noticing...
Yes, the fist 2 digits are the diameter, the second two are he length, in millimeters. The final 0 is somewha redundant, most people say it's to label the battery as cylindrical. I too hate proprietary batteries, and it's very annoying that they seem to only be getting more common :/
I think these will become popular with high end mid power torches, they're not really suitable for high power ones since even if they were capable of dishing out the current you'd need beefier components to deal with said current draw and you also lose more efficiency the lower the voltage and higher ampage you run things at also meaning you'd ned beefier cooling solutions 18650's and 21700's i dont think will be going anywhere due to their use in compact torches.
21700 definitely won't be going away, I do wonder if they will fully replace 18650s at some point though. Personally I still love the 18650 form factor
18650 now is the little brother that offers good performance in a very compact form factor. I don't see it going away, only becoming slightly more niche. 21700 is a very good size, but not exactly pocket-friendly even in its most compact offerings like the S21A. Another use I see for these big batteries is another mid-power application: lanterns. They're about the perfect size to fit in a lantern the size of a Coleman, for example. And runtime matters more than brightness, so win-win.
Hmm.. Proprietary, No point in buying a light with a new battery type that could be obsolete. I'm sticking to 21700. It's a matured technology, and it's standardized.
I'd love a scuba light powered by this battery, at a lower lumen, preferably adjustable(1,000 to 5,000 would be plenty, or with an adjustable focus). Would be plenty enough battery life for long dives, even multiple long dives in a day.
hmmm, 32000 mAh @ 3.7 v = 118.4 Wh. That's in the 100 Wh - 160 Wh range, which will require special permission from the airline. Depending on the airline, that can be painful.
These next gen car batteries are going to be dirt cheap once production scales up. Same goes for those big chinese LEDs like the SFP55. We might start to see 100'000 lumens flashlights at the supermarket xD
This is a great application for this cell type! Tesla is only able to make EVs use this cell type because of their tab-less design. The length of the rolled sheets makes the internal resistance very high so current draw and voltage sag become a huge issue. Thanks to them creating a tab-less design, they can increase the current input or output by 6x and sacrifice nothing in the process! These batteries are really pushing the limits of technology, and I glad Tesla is so transparent about the design and engineering behind it!
I believe 18650 will continue to be the most popular size for flashlights. 21700 replaces 26650 more than 18650, so 26650 may be the format that gets abandoned.
I personally still like to use 18650s, but it seems that 21700 has replaced both formats, I see many companies moving away converting from 18650s to 21700s. But 26650 are definitely done I think.
I agree that 21700 has supplanted 26650, but for 18650 it's debatable. 18650 is not-insignificantly smaller _and_ lighter than 21700, both in the hand and in the pocket, so in lights that prioritize compact size I presume it will continue to be a dominant presence.
@@DinnerForkTongue I agree about 18650. I have lights for 18650, 21700 and 26650. And 21700 makes the light significantly bulkier than 18650.

@@patricj951 "significantly" is an overstatement...I can clearly see the trend that 21700 will eventually replace 18650s. higher density with negligible size increase.
I just got a 46950 flashlight with quad xhp70.3 chips. it's only 8000 lumens due to the low voltage and cheap circuitry. I still consider it a good deal for under 100 dollars price with a battery included. It can sustain 2400 lumen output for 7 hours, while the same model with 21700 batteries can only do 3.5 hours.
This battery alone being over the limit for onboard aircraft carrying is a bummer for me 😅 its also no go as a check-in baggage, so you actually would need to ship this battery as a DGR cargo with a licenced aviation company 😂
It's size will not allow this form factor to become the industry standard. People rarely use all these super high brightness 100000000 lumen flashlights, because they are too big to carry in a pocket or a backpack, costs more, hard to recharge, hard to get replacement batteries and overall less convenient. Yes they have specific use case scenarios like Police, Coast guard, maybe some specific kind of technicians Idk. But the point is not enough people will buy them thus this new battery form factor will not go mainstream. Also for EVs there might be heat related problems with this 46950 form factor because of it's very high volume to surface area ratio compared to 21700.
Very interesting video, good information, thanks. I have been missing your videos, would appreciate more content more often. See you again soon hopefully
This won't meet enough high power draw requirements compared to a bunch of 18650s or 21700s in series. That's gonna be a huge problem because of insane amounts of heat generation and inadequate power.
You have forget speaking about one thing that is charging time, with multiple cells charging could be significantly shortened. With one cell depend of charging current that should be being on safe side 1/10C you need at least 11+h, of course if 10A of current is delivered by this cell without any issues than you could as well charge at that amperage but then you need quite hefty power supply and quite thick wires and some state of the art mount for making resistance of the junctions as low as possible because at that amperage any resistance will generate a lot of heat.
What about the energy density weight wise (mAh/g)? For example, Samsung: 18650-35e 3500mAh/50g, 21700-50e 5000mAh/70g, so the 18650 slightly beats the 21700. Same for Murata 18650VTC6 vs Molicel 21700-45p.
The F60 was available at the time of filming this....Pretty sure FEB's 6Ah 21700 has been around for a year. That voltage drop you're getting on the start of your test doesn't look right. Are there voltage sensing leads on your CBA?
Same here man. Where to buy 46950's. I have just ordered a powerful flashlight that uses them. I just hope they will be widely available by the time I need to replace.
Do you need arc welder goggles to use these on Hi??!! You Will if you look INTO them! Eyes... As we said in the lab, "tell the cyclops not to look into the laser again". Things are getting out of control crazy!
That's not a battery issue, that's a thermal mass/physics limitation. Unless you want to start implementing active cooling on edcs then there only so much heat a small flashlight can expend
Nope, id rather carry a few 18650 or 21700, even 21700 Olight. Or even a pack of AA for my Fenix HP16R! A single cilinder at that diameter its more inconvenient to carry. Dont get me wrong, i love Lumintop and i own 2 of them.
Let hope they didn't lie about the Specs - MAh - Chemistry - lie about Safety Best LED Flash light i have is A few of the Cordless tool Bands (Ryobi - Makita - Milwaukee -DeWALT) where the battery Pack (INC BACKPACK )can be Switched out and a Fresh Pack Swapped in) and can use the pock for other Things Even a Power Station (AC 120V 240V + USB-C PD 5V, 6V,9V, 12V 20V~48V 30W ~ 240W) & Cordless tool Eco systems
How does one go about eductaing themselves on all this LiIon cell spec stuff with no prior electrical education whatsoever? I just want to play with cool flashlights, but it seems I'v lived my life wrong and am now just not educated properly to be able to. At least not safely.
Lumintop also has the GT46 that has a 46800 cell compared to the GT46 using the 46950. I like the GT46 due to the full tube knurling that the GT4695 doesn’t have. I asked Neal at Neal’s Gadgets about the 46800 cell and he said it was more like 3x21700. I only found one listing for 46800 replacement batteries but you have to buy a dozen. I like the GT46 a lot but hesitant to buy given it uses this hard to find battery should I need a replacement.
I don't think Tesla publishes actual data for their 4680 cells but people have derived from the pack size that it works out to 26.136Ah per cell (I think that's the Tesla 4680 V2?). That's about 4.75x of the 21700 he showed that was the highest real capacity he's seen (5500mAh).... And that quoted capacity of the Tesla cell is pretty much EXACTLY were I would expect it to be based on this 46950 shown, power scales nearly perfectly with height and the Tesla cell has less power but slightly higher power density per mm height which is what I would expect given that it doesn't "waste" several mm of that height with the protection circuit the 46950 show has. In fact given that the Tesla 4680 V2 cell is generally recognized as being one of the shared leaders when it comes to power density I'll give the 46950 cell maker here a "well done" award.
This is close to the new battery BMW will be using in EVs. It's the INR46950 and it's close to the 4695 specification but it's 96.5mm tall rather than 95mm. I wonder if there will be a flashlight for those?
You have an.....interesting hobby. Not being a flashlight guy, that is way too big. I could see pillow batteries being more popular than that thing. That's industrial sized. Now I'm curious, what type of non-standard flashlights do you have? I bet a few UV, but what else might there be?
It's going to suck holding these big lights in your mouth while working on your computer or TV, because you are too cool to wear a headlamp! You might be able to make a "mink scarf" 2 cell battery pack with electric leads to a headlamp. The trick would be to use alligator clips that would be cheap enough to replace every few weeks. The wire, from the pack to the light, 's flex would cause frequent wire failure. They also would be too heavy for a wrist light. Flashlights functionally make every user handicapped, like any amputee, because when you need to see, you usually need to be also using both of your hands!!
The future of flashlights for folks that want to start a fire with light and have big hands. However the trends have been mini flashlights. A hard sell for that. Nothing mini about it, you could power a E-bike with that. If folks can talk the D cell name brand flashy makers to make a wider body for two of them. The old phototecnics and laser pointer forum folks from the waybacks day will go nutty.
I'm wondering if these Lumintop cells came out of a used Tesla battery pack; can someone that might have better access to resources investigate please?
If you are going to bother making a light this big just so I can find my keys in the dark, why not go the extra 4 feet and add a metal detector to the end of device?
The world you live in must be nice to think that a 200 USD flashlight is the CHEAP version. 30 USD or less is cheap, anything over that is expansive; and anything over 100 USD for a Flashlight is just absurd. Unless you've got more money then brain cells, then spent it as you will... Cheer's....
I said, for what is, it's cheap. Most lights of this type and performance will cost $300+. If you want something cheap, I just uploaded a review of a light that costs less than $2: ruclips.net/video/CdEEJFlJsco/видео.html
I am using a 26650 and I have no complaints. They are really big by comparison to other commonly used cells since these are more like the size of a C or D cell and considering the ubiquitous 18650 we all have heard of by now the 26650 is even somewhat big compared to those.
I used to like the potential of 26650 until 21700 became more or less the standard and surpassed its bigger older brother. Nowadays I doubt I'll get one - it's either 21700 or maybe the newer 26800.
I get that lighting is your thing, but even still thinking of a battery size that most people could just about hold onto the raw cell comfortably on its own without casing and thinking "FLASH LLIGHTS!!!" makes me think "square peg round hole, when you have a hammer everything looks like a nail, etc"
It’s the same in vaping, we started out with 18650s then went to 26650 cells then we moved to 20700 and 21700 cells although some mods can utilizes 4s lipos.
In _this specific size,_ with technology as is, you will never get anything worth the hassle for 40 dollars. But you can go smaller and lighter and much less powerful, which isn't necessarily a bad thing. And in those applications, I'd say 40 bucks could be considered overpriced. Look at Sofirn, Wurkkos and Convoy, for example.
Flash lights seem to discharge by themselves when not in use. Since I use them rarely, I find them discharged and have to look for new batteries when I get around to using it. To avoid fire and discharge during travel, I cut out a circular piece of plastic and put that in the flashlight. At the destination, I remove it. Once the TSA guy asked me to turn it on, and I had to open it and show him that the flashlight works. I wonder any of these fancy flashlights solve this discharge problem by complete disconnect in storage.
They do - anything with an E-switch requires a small amount of current to operate, which means the battery will very slowly die over time (though it's usually an extremely small drain). However, lithium-ion batteries naturally self-drain a tiny amount as well, so they shouldn't be stored for longer than about a year.
Tesla have an even larger 46120*0, they might replace the large 8x 21700 lights - 1x 46120*0 battery would be better than 2x 4695, as that one would be 19cm long
Not only for pop can blasters, this battery size is just about perfect for fitting in a lantern. That alone gives it plenty of appeal for the camping and outdoors market.
Sweet now make a triple battery light with them 🤠

I am more interested the Acebeam implement the 46950's in their X75 or X50, or Lumintop implements it in their GT90 or GT94.
I'd 100% take those even if they ran a bit dimmer.
This battery alone being over the limit for onboard aircraft carrying is a bummer for me 😅 its also no go as a check-in baggage, so you actually would need to ship this battery as a DGR cargo with a licenced aviation company 😂
Is that chungus the Tesla car battery?
When did $165 to $200 become "cheap" for a flashlight??
For _this category_ of torch, it's very much cheap.
150 to 200 for a flash light is far from what normal people would call cheap....
Muggles don't have the same definition of flashlight as us anyway.
It's size will not allow this form factor to become the industry standard. People rarely use all these super high brightness 100000000 lumen flashlights, because they are too big to carry in a pocket or a backpack, costs more, hard to recharge, hard to get replacement batteries and overall less convenient. Yes they have specific use case scenarios like Police, Coast guard, maybe some specific kind of technicians Idk. But the point is not enough people will buy them thus this new battery form factor will not go mainstream. Also for EVs there might be heat related problems with this 46950 form factor because of it's very high volume to surface area ratio compared to 21700.
Very interesting video, good information, thanks. I have been missing your videos, would appreciate more content
more often. See you again soon hopefully
Now that is a proper battery for real EDC pocket flashlight 😂
Perfect fit for my jeans coin pocket!
This won't meet enough high power draw requirements compared to a bunch of 18650s or 21700s in series. That's gonna be a huge problem because of insane amounts of heat generation and inadequate power.
You have forget speaking about one thing that is charging time, with multiple cells charging could be significantly shortened. With one cell depend of charging current that should be being on safe side 1/10C you need at least 11+h, of course if 10A of current is delivered by this cell without any issues than you could as well charge at that amperage but then you need quite hefty power supply and quite thick wires and some state of the art mount for making resistance of the junctions as low as possible because at that amperage any resistance will generate a lot of heat.
You forgot the 26980 i believe, i have a convoy that uses it and its great.
Isn't 26980 a 26800 with protection circuits?
Imalent left the chat
What about the energy density weight wise (mAh/g)? For example, Samsung: 18650-35e 3500mAh/50g, 21700-50e 5000mAh/70g, so the 18650 slightly beats the 21700. Same for Murata 18650VTC6 vs Molicel 21700-45p.
The F60 was available at the time of filming this....Pretty sure FEB's 6Ah 21700 has been around for a year.
That voltage drop you're getting on the start of your test doesn't look right. Are there voltage sensing leads on your CBA?
Incredible! I didn't realize the terms "reasonably compact", and "affordable" could be so relative.
where can i buy these 46950s? google finds nothing about where to buy them.
Same here man. Where to buy 46950's. I have just ordered a powerful flashlight that uses them. I just hope they will be widely available by the time I need to replace.
@@DuaneOnAFlatPlane I found them on Alibaba
Do you need arc welder goggles to use these on Hi??!! You Will if you look INTO them! Eyes... As we said in the lab, "tell the cyclops not to look into the laser again". Things are getting out of control crazy!
TBH what we need more are high-power compact lights that don't step down after a few seconds or so.
That's not a battery issue, that's a thermal mass/physics limitation.
Unless you want to start implementing active cooling on edcs then there only so much heat a small flashlight can expend
Nope, id rather carry a few 18650 or 21700, even 21700 Olight. Or even a pack of AA for my Fenix HP16R! A single cilinder at that diameter its more inconvenient to carry.
Dont get me wrong, i love Lumintop and i own 2 of them.
Let hope they didn't lie about the Specs
- MAh
- Chemistry
- lie about Safety
Best LED Flash light i have is A few of the Cordless tool Bands (Ryobi - Makita - Milwaukee -DeWALT) where the battery Pack (INC BACKPACK )can be Switched out and a Fresh Pack Swapped in) and can use the pock for other Things Even a Power Station (AC 120V 240V + USB-C PD 5V, 6V,9V, 12V 20V~48V 30W ~ 240W) & Cordless tool Eco systems
How does one go about eductaing themselves on all this LiIon cell spec stuff with no prior electrical education whatsoever?
I just want to play with cool flashlights, but it seems I'v lived my life wrong and am now just not educated properly to be able to. At least not safely.
Two of these in future Ace beam flash lights 100k lumens for 10 minutes than 50k for 1 hour probably,....
Lumintop also has the GT46 that has a 46800 cell compared to the GT46 using the 46950. I like the GT46 due to the full tube knurling that the GT4695 doesn’t have. I asked Neal at Neal’s Gadgets about the 46800 cell and he said it was more like 3x21700. I only found one listing for 46800 replacement batteries but you have to buy a dozen. I like the GT46 a lot but hesitant to buy given it uses this hard to find battery should I need a replacement.
Thanks for the info, I do wonder which will prove more popular, the 80mm or 95mm version.
Reminds me of the early days of 21700 when it competed toe to toe with the 20700.
I don't think Tesla publishes actual data for their 4680 cells but people have derived from the pack size that it works out to 26.136Ah per cell (I think that's the Tesla 4680 V2?). That's about 4.75x of the 21700 he showed that was the highest real capacity he's seen (5500mAh)....
And that quoted capacity of the Tesla cell is pretty much EXACTLY were I would expect it to be based on this 46950 shown, power scales nearly perfectly with height and the Tesla cell has less power but slightly higher power density per mm height which is what I would expect given that it doesn't "waste" several mm of that height with the protection circuit the 46950 show has. In fact given that the Tesla 4680 V2 cell is generally recognized as being one of the shared leaders when it comes to power density I'll give the 46950 cell maker here a "well done" award.
This is close to the new battery BMW will be using in EVs. It's the INR46950 and it's close to the 4695 specification but it's 96.5mm tall rather than 95mm. I wonder if there will be a flashlight for those?
I would like to see these come into the hobby grade Remote Control world of airplanes, helicopters, boats, and ground pounders.
You have an.....interesting hobby. Not being a flashlight guy, that is way too big. I could see pillow batteries being more popular than that thing. That's industrial sized. Now I'm curious, what type of non-standard flashlights do you have? I bet a few UV, but what else might there be?
It's going to suck holding these big lights in your mouth while working on your computer or TV, because you are too cool to wear a headlamp!
You might be able to make a "mink scarf" 2 cell battery pack with electric leads to a headlamp. The trick would be to use alligator clips that would be cheap enough to replace every few weeks. The wire, from the pack to the light, 's flex would cause frequent wire failure.
They also would be too heavy for a wrist light.
Flashlights functionally make every user handicapped, like any amputee, because when you need to see, you usually need to be also using both of your hands!!
Whats the current run time for the new battery 🔋? Under constant use until it dies ? Hours days ? Weeks?
Depends on the item that said battery powers, naturally.
The future of flashlights for folks that want to start a fire with light and have big hands. However the trends have been mini flashlights. A hard sell for that. Nothing mini about it, you could power a E-bike with that. If folks can talk the D cell name brand flashy makers to make a wider body for two of them. The old phototecnics and laser pointer forum folks from the waybacks day will go nutty.
It would be great if the FENIX LR60R had this type of battery. It’s a similar size flashlight but it’s only a 4000 mah
How did RUclips think I would be interested in ' channel that thinks at 209 dollar flashlight is cheap? Everything I do reeks with cheap skatyness.
should see the size of cells we use lol ! and ours are high rate !
I'm wondering if these Lumintop cells came out of a used Tesla battery pack; can someone that might have better access to resources investigate please?
Cheap Flashlight for only 200$ and I bought my Laptop twice that price.
"milli" makes big numbers, 32 Ah looks not so great. Yesterday I drunk 2000 ml beer !
I'm thinking some kind of LED flashlight-lantern with (4) 46950's
Size D battery does just fine for the giant flashlight.
Anyone know how to best disassemble the GT4695? mine seems to be gorilla tightened.
Be my guess that these are the new Tesla cells (B stock) but 10mm longer with bms charge discharge protection added
This thing could burn the Luten Car Park down by itself.
Dang, your flashlight collection equals my annual food and fuel budget 😳
Why donwe insist on using such big ass numbers like 30000 mah. Why not just say 30Ah because that is the same thing.
How did you safely remove the battery? They are lock tightened now.
because 32,000 mAh sounds more impressive than 32 Ah
If you are going to bother making a light this big just so I can find my keys in the dark, why not go the extra 4 feet and add a metal detector to the end of device?
Small battery with huge capacity are time bomb they can blow and burn anytime 😂😂😂
And, with the optional timed short circuit switch, it doubles as a hand grenade!
Candles look and smell so much better I'm old and resistant to change
I plan on making an ebike in the coming months and these would fit the bill quite nicely.
Why cant I find any information on this battery?
in 2 years Panasonic is going to blow your mind
21700 -> “electric candlestick?”
4x21700 is like 4xAAA in a flashlight. Just use a single 46950! 😛
What is the glow temperature of Mach v2?
Good video LuxWad
wish you'd actually reviewed the lights. the 4695 looks great
There are detailed runtime tests here: budgetlightforum.com/t/46950-flashlights-tested-lumintop-mach-v2-gt4695/221787/1
The world you live in must be nice to think that a 200 USD flashlight is the CHEAP version. 30 USD or less is cheap, anything over that is expansive; and anything over 100 USD for a Flashlight is just absurd. Unless you've got more money then brain cells, then spent it as you will... Cheer's....
I said, for what is, it's cheap. Most lights of this type and performance will cost $300+.
If you want something cheap, I just uploaded a review of a light that costs less than $2: ruclips.net/video/CdEEJFlJsco/видео.html
Next flashlights will use 3 or 4 of these
I am using a 26650 and I have no complaints. They are really big by comparison to other commonly used cells since these are more like the size of a C or D cell and considering the ubiquitous 18650 we all have heard of by now the 26650 is even somewhat big compared to those.
I used to like the potential of 26650 until 21700 became more or less the standard and surpassed its bigger older brother. Nowadays I doubt I'll get one - it's either 21700 or maybe the newer 26800.
I get that lighting is your thing, but even still thinking of a battery size that most people could just about hold onto the raw cell comfortably on its own without casing and thinking "FLASH LLIGHTS!!!" makes me think "square peg round hole, when you have a hammer everything looks like a nail, etc"
Large lights in this form factor sell quite well
It’s the same in vaping, we started out with 18650s then went to 26650 cells then we moved to 20700 and 21700 cells although some mods can utilizes 4s lipos.
No but it’s the future of torch batteries!
so we're returning to the D cell format....
If the cell has internal bms, the lower measured capacity is probably due to the bms not using 100% cell capacity to increase it's cycle life.
Does anyone know what happened to the "Ultra Capacitor" battery? Purposely they charge in seconds. I don't see or hear about them anymore...
$165 - $290 CHEEP flashlights?! OK Mr. GotRocks! $40 is a cheep flashlight. 🔦
In _this specific size,_ with technology as is, you will never get anything worth the hassle for 40 dollars.
But you can go smaller and lighter and much less powerful, which isn't necessarily a bad thing. And in those applications, I'd say 40 bucks could be considered overpriced. Look at Sofirn, Wurkkos and Convoy, for example.
This the type of flashlights the need to find bigfoot 😂
Flash lights seem to discharge by themselves when not in use. Since I use them rarely, I find them discharged and have to look for new batteries when I get around to using it. To avoid fire and discharge during travel, I cut out a circular piece of plastic and put that in the flashlight. At the destination, I remove it. Once the TSA guy asked me to turn it on, and I had to open it and show him that the flashlight works. I wonder any of these fancy flashlights solve this discharge problem by complete disconnect in storage.
They do - anything with an E-switch requires a small amount of current to operate, which means the battery will very slowly die over time (though it's usually an extremely small drain).
However, lithium-ion batteries naturally self-drain a tiny amount as well, so they shouldn't be stored for longer than about a year.
So much hydrogen fuel cell technology!😢
Tesla have an even larger 46120*0, they might replace the large 8x 21700 lights - 1x 46120*0 battery would be better than 2x 4695, as that one would be 19cm long
