Massive New Flashlight Battery!

[@DinnerForkTongue]

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.

[@StucklnAWell]

Sweet now make a triple battery light with them 🤠

[@BattleshipSailorBB63]

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.

[@TobyCostaRica]

Finally something bright enough to attach to my keychain

[@MAGGOT_VOMIT]

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.

[@ivanleonidovlz5147]

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.

[@DinnerForkTongue]

That's one heck of a use case. Please keep us posted on your experiences and findings with this battery.

Very nice introduction on the new 46950 battery, thanks.

[@alexdrockhound9497]

i love huge batteries. these will be great for all sorts of home projects. im really excited to see what lights companies come out with for these.

[@Drunken_Frog_40000]

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.

[@DinnerForkTongue]

This would be great for lanterns, though. I'd take one urbexing.

[@gonzalez7805]

Love seeing new options for flashlights... Cant wait to see what some of the other brands come out with ...

[@rilosvideos877]

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...

[@lumntoob999]

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.

[@ethan-lumencraft-]

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.

[@nikhilmathew5478]

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.

[@DinnerForkTongue]

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.

[@lumntoob999]

@@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.

[@Tevon93]

@@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.

[@Sylvan_dB]

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.

[@OnlyKaerius]

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.

[@XiaoMingMC]

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.

[@axeami1354]

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.

[@ethan-lumencraft-]

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

[@DinnerForkTongue]

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.

[@stultuses]

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.

[@dschwep7]

[@margarohernandez9654]

Haha eso Sería como una gran máquina de vapor ♨️

[@sloanNYC]

$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...

[@ethan-lumencraft-]

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 :/

[@silentbob1236]

Screw the flashlights, where can I get the 46950!

[@patricj951]

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.

[@ethan-lumencraft-]

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.

[@DinnerForkTongue]

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.

[@patricj951]

@@DinnerForkTongue I agree about 18650. I have lights for 18650, 21700 and 26650. And 21700 makes the light significantly bulkier than 18650. Thrunite still uses 26650 with a few models and the tube size is very good in the hand when the head anyway is pretty large. But with several of my 18650 lights a 21700 tube would not be desireable. In some cases 18650 tube is just right.

[@masondawson4061]

Incredible! I didn't realize the terms "reasonably compact", and "affordable" could be so relative.

[@Flutter9i6]

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!

[@BlenderRookie]

When I buy anything that runs on batteries, I skip anything that's proprietary.

[@christopherleubner6633]

46950 is the one used for UPS systems, some EV batteries, and grid storage systems. 3 in series can jump start a car or truck with a 12V system

[@Flutter9i6]

Most UPS systems use lead acid, and the ones that don't are typically 18650s. If they were to use a 46xx it would be a 4680(aka 46800) which is the same cell type but no integrated protection circuit. You don't need cell level protection if your already have a balancer, infact it may create an issue. You also probably wouldn't want to jump start anything with 3 of these unless you know you have a Tesla made 4680, because only they have a tab-less version at the moment. Using a tabbed version would be dangerous and likely damage the battery.

[@spyharpy]

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.

[@ethan-lumencraft-]

Thanks for the info, I do wonder which will prove more popular, the 80mm or 95mm version.

[@DinnerForkTongue]

Reminds me of the early days of 21700 when it competed toe to toe with the 20700.

[@Torbjorn.Lindgren]

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.

[@PiercingTheDarkness]

It looks like you have a poor connection on your Anderson connectors for the CBA. I had real trouble with mine and so I soldered the leads directly. You have the same CBA as me and it looks to be the exact issue I was facing. Cleaning with IPA helped, but it never lasted.

[@charleshines5700]

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.

[@DinnerForkTongue]

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.

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.

[@ethan-lumencraft-]

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.

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.
