"Don't try this at home by the way...What am I saying. Try it at home if you wish. I'm doing it" -Clive 2016

"I could enter by the other end, this is going to end in tears isnt it" oh my

tearing into a lithium cell with pliers... safety squints engaged!

8800mAh is the total charge you can put into it over the cycle life of the cells. ie 10 cycles of use, and 5 were used in the factory.

13:53 “What’s the best way into this... Violence, I’m guessing.” :-D

I was very disappointed when no sand poured out of the battery. On a side note, those chargers are hilarious.

Serious request: You should start selling t-shirts with slogans like "Explosion containment pie dish" and "Vise of knowledge" etc. on them

Heh. I bought some Ultrafire "6000 mAh" cells from ebay (knowing full well they were generally about 1000 ma, but quite cheap and with a protection circuit), and I opened one up out of interest. Small cell as expected. And compacted *sand* to make it feel "quality in the hand". Lol. Chinese sellers are such good scammers.

"This isn't a good idea. Excellent." Why I love you.

Banggood is advertising 9,900 mah cells. Someone called them out and they came back with an odd run around reply and in the end they said they were really 1,500 mah.

Top tip - one of those adjustable pipe cutters work very well at opening battery cases - you can get them at Wickes, B&Q, etc.

I love it when these videos arrive just in time for dinner.

I'm interested in what kind of ebay feedback you leave lol

This 18650 over-rating is getting silly now.

14:52 *_"Don't try this at home, by the way cause ah, well I mean, who am I to say you know. Try it at home if you wish"._* 😉👍🏻 No other KZfaqr has ever had the guts to say this before. Brilliant. Thanks so much for sharing. 👌🏻

Whenever i feel that humanity has some hope, all i need is a video about chinese "quality products" to remind me of the reality.

"What's the best way into this? Violence, I'm guessing..." And that's what electronics is all about. Great stuff. Informative, and entertaining, as always. Nice one.

you know what this means Clive you now have to plug the car charger in while it's on muhahaha

If the power goes out and the people next door ask to barrow a flashlight I bet Clive tells um oh sorry I don't have one.

One of these days, your nickname will be "The 3 Finger guy" But... You're the best Ever!!!! Your sense of humor is great!!!

There was a time when you could report a U.K. supplier to Trading Standards and action would be taken against them for selling faulty, dangerous or fraudulently advertised goods, but sadly it doesn't seem to be the case any more what with the cuts to council budgets and the proliferation of resellers of Chinese tat. It'll probably take something truly horrific to happen before we see any change.

Your explosion containment pie-dish won you my subscription

Hand rolled like a cuban cigar.

Your such an intelligent man. I have watched 100+ of your videos and i love every single one of them. Just listening and learning from each. I started watching with little to no knowledge in electronics i thought i knew abit but you have showed me otherwise lol. I love learning and watching these videos defiantly teach :) Thanks for making videos and i look forward to watching them in the future :)

I knew it... "It seems quite a good deal... except..." That has to be one of the classic lines form you Clive. Nice.

Explosion containment pie dish. This is my new favorite channel.

You are way too cool Clive! You tear into the same products I buy but that I have not dared to peer inside. Keep making these vids as it's far more entertaining watching and listening to you! Cheers from Texas.

Just a thought. Would a plumbers' rotating tube cutter be a handy cell opener?

Clive, get one of those Atomic LED flashlights advertised "As Seen On TV" that claims to have some ridiculous amount of lumen output.

ANOTHER good one Clive. A thousand thanks.

I think I'd rather have a classic 18650 torch with a sliding focus control.

Thanks Clive for the video. I have never deconstructed a Li++ battery. Appreciate the view of its internals..

"What am I to say? Try it at home if you wish, I'm doing it!"

might get one of these, thanks Clive. I need a new car

Cool linemans pliers, used to wear a set of those with my Amy field uniform, way back when I was a field wireman.

Always nice when the ECP-D comes out. :)

"Of course, AvE just saws it in half" - Shots Fired!

The famous last words of an electrician: "what could possibly go wrong?"

For getting the lithium cell open, toenail clippers work well to pry open the sealed end. Then once the sealed end is lifted around the circumference, needle-nosed plyers can be used to peel the outer casing down by rolling it.

"Don't try this at home, I mean who am I to say? try at home if you wish, I'm doing it" -bigclivedotcom PSA of the year!

_"violating the integrity of the curvaceous cell in a dramatic manor"_ I love Bigclivedotcom

Gah... Now I feel like a horrible child... I've sent one of these to my parents... I'm glad they don't really use it too often, time to give them a call, see if I can get them to see if it's made just as cheaply

Clive, in the states we can buy knitted kevlar "tradh handling" gloves in sny hardware store, about $5 a pair. They're fireproof, cutproof, good protection and good dexterity when you are working with things that might bite. In case you decide to become a pianist and need all those fingers. :-)

Clive your knowledge of electronics, circuits and electrics is incredible but what I find just as impressive if not more is your knowledge of dismantling shit.

This is going to end up in tears... EPIC!

Thanks Big Clive.

I picked up a flashlight with the same exact head but on a regular type flash lantern type body, it takes 3 18650's the entire unit is made from aluminum, rather heavy and extremely nice when working in tight areas, has a top handle and will stay on flat surfaces rather nicely

clive, what you need is a fine-toothed hack saw, a clamp, and a guide rig so you can saw open batteries the long way (just enough to split open the case) to the point cutters can do the rest of the job

xD I like this guy always going out of his way and tearing into stuff- when he can. I like how he does all the math behind it as well, very good. I like tearing into electronics myself, and I can say that he deserves more subs. Best of KZfaq I'd say. BigCliv- Thank you.

WOW! I noticed the on/off button looks similiar to what I have in my chinese headlamp, otherwhise is, ofc, looks completely different. It has the SOS mode too! I've had it for many years and didnt know about it :D

good video bigclive always good video for the channel

Clive, you know we all wanted you to charge the cells with the included car adapter. Also, you should replace the charge jack with a micro USB jack and add a TP4056 charger board.

Sweet, I bought one of those a couple months ago for a shop/work light.

Good video Clive. You know the car charger and batteries must be tested. I may have a line on Titanium pie plates (bomb shields)

Regarding the low capacity batteries: Could it be that they are produced in such numbers that the battery manufacturer(s) have/has developed a QC process akin to resistors and such components that they separate the failed cells out by how much capacity they have then sell them to mass production houses so that the battery producer still makes money even on the "bad" ones.

I just saw this or a similar one on amazon looking for a zoom led flashlight. It seems a pretty cool idea to make a device like this.

"Jam packed with chemicals", Now that sounds like a good time at Clive's house to me.

you should definitely put one of the batteries on to charge with the car charger and leave it to see what happens. in the pie dish ofc, so its guaranteed to be safe

I wonder if the loose wrapping of the electrodes in the cells was done purposefully to make them more tolerant of overcharging? The extra air-space could provide expansion room for off-gassing of electrolyte during overcharge, which could then recombine later after the charger has been removed.

I bought a cheap 'Cree' bicycle light with four 18650 Li cells. When I took the cells apart two of them were in fact dummy cells with no functionality at all! Replaced them with two Li cells salvaged from a very old Nokia phone and all is well three years later.

I want one of these, not to use but to rip apart and use the focuser on a flash project i'm working on!

3500mah for the new Sanyo NCR 18650GA 10amp ones, love love love them.

The lens assembly is.. rather reasonable, I was surprised.

I bought a couple of these lamps about a year back, without the batteries thankfully (and considerably cheaper), the lamp unit itself actually works pretty well and is decently made, but mine has a UV element (about 390nm) instead of the flashing mode . This UV mode wasn't mentioned at all by the seller, but makes it about twice as useful to me. The chargers which came with them is 4.2v, but seemingly cut out the instant any load was applied to them, To make it worse, one of them fell apart leaving a pin in the power socket. The chargers went straight in the bin after that.

thats a neat heatsink for the led

Come on clive, that's a high quality hand rolled Chinese cell. You don't get that kind of quality and uniqueness anywhere else!

One tp4056 based board, a dremmel cut slot (or repurpose existing charge port hole) for its the micro USB and you get a plethora of charging options and battery protection for less than a dollar.

Good to know, many cheap headlamps have suspiciously cheap versions which include the charger and batteries.

Why do they insist on putting that irritating flashing mode on led torches

LEDs in lights like that usually are Cree, though they tend to be low-binned Crees since it's cheaper and easier to get a low-binned Cree than it is to try and knock off Cree.

Regarding li-ion battery capacities, currently the highest capacity available at the moment is 3600mAh and is produced by Panasonic (and possibly others), but they are quite expensive. I recently found a 4-pack of 3400mAh (and they are, I tested them) Panasonic batteries for about £10. Was very pleased!

Hoorah! New episode!

Glad you put gloves on :)

Looks like somebody bought the light, the batteries, and the chargers separately in bulk and soled them as an ( inappropriate ) set?

I suspect that the construction of the cells is done to allow the scammers to use the same equipment to make them as the real cells. All they have to do is temporally change a setting on the winding machine during the night shift and they can switch over to fake crap. Plus they don't have to worry about scrupulous potential customers wanting to inspect the factory and finding extra incriminating machines.

I actually have a few head lamps with similar features, probably the same stuff. Similar chargers and batteries were bundled with it and those were also quite bad. One time I forgot and actually used wall socket charger with this thing but I used Panasonic cells. All breakers popper right away as real batteries have much less resistance than those cheap things. Also those chip ones had so much resistance that they actually were able to charge with 12V. That was garbage anyways. The light is great though, I just use proper cells and dedicated charger, I never use any bundled chargers.

Take a shot every time there was a sexual innuendo in the 18650 teardown

Speaking of focus and LEDs, do you know what I should search for if I want a discrete LED with an extremely focused beam? I want to do an in-class experiment with mirrors/lenses, but I am concerned that if I use a (low power red) laser that children might not be smart enough to blink/look away if it's accidentally reflected in their direction. I thought maybe just a non-laser LED might be safer, but I am not sure if they come in versions with a low (high?) viewing angle.

How about rigging up a Dremel + disc in a frame, with some kind of non-metallic hand cranked chuck? Whizz it round one end like a mini can opener, turn over and do the other; then a final cut by a second handheld Dremel + disc along the length, and you will have opened it up in 30 seconds. On the downside, there'll be less fear of sudden detonation!

I used a plumber's 15mm pipe cutter to get into a fake 18650 -- just the tool. I cut the top off the cell rather than the bottom, and the air gap was immediately evident.

you could use one of those pipe cutters to open them.

I like your videos, they are fair. I like them mostly because you are not angry like the others. But use some real "fireproof" gloves. If one day a lithium battery burns you will get seriously injured. The plastic of your gloves can melt on your skin. I say that for you, and for the peoples that will do the same after viewing your videos. Please keep continuing to be so kind on your videos. I really like it.

The way you're so casual about shit blowing up makes me laugh everytime, you have no fear Clive, no fear at all you madman!

I was expecting both chargers to be 5V. The wall charger disappointed me, but the car charger is pretty exciting!

Finding all these new devices on Ebay must be a practice thing - when I go on and look around I spend countless hrs scrolling through tons of identical, me-too items. Never seem to find any variety - the Zen of Clive eludes me.

Could you use your little pipe cutter on that battery as if it were a piece of pipe? Adjustable Rigid wheel cutters could do it.

Could you measure the voltage when you connect the car adapter to your bench power supply @ 13.8 V but then when its gone through the circuit board (where it goes into the batteries) ?

'I could enter by the other end' - bigclivedotcom 2016 (so much inuendo in the episode haha)

Would like to have seen inside the 3V supply. How safe is it.

Just a thought...do Clive's dustmen get danger money?

The 819L is actually a watchdog voltage protection chip made by Maxim.

You know you have to use the car charger and see what happens, right? You can't get away with teasing us like that. Nice video.

They are selling this on Ebay as a 30 watt light. 30W Rechargeable Convex Lens Lamp Focusing Unless they are going for an incandescent equivalent, it's a bit cheeky.

Love the pie dish :-)

they have high drain 18650 cells at any e cigarette shop, and chargers which will also charge the 18350 cells for your k klone pipe.

Chinese quite often use Li-Ion cells from recycled notebook accu-packs. You can usually find it out seeing spot-welding marks on the bottom of the cell.

the same cells used in pound land battery banks, i have to say the chemical smell is almost like a perfume smell kind of nice.

Be it 24 Dollars, 24 Euro or 24 Pounds, that would be a very surprising cheap price for 3 18650's. They cost 15-20$ for decent quality ones, not that much less for cheap ones.

I would just deattach the battery pack from the PCB and put the contacts on a seperate 18650 charging board with protection. Then stick the output contacts to the actual battery pads on the PCB. Also of course solder the input wires onto the 18650 charger board, toss the chargers to a different universe and just use a USB --> tip plug of the proper size to charge/use the batteries/light.

Shaking like a leaf while you were dismantling that cell... LOL.
