Using salvaged lithium cells to power LEDs directly. (with protection test)

Ғылым және технология

This video is just a demonstration of how salvaged lithium cells can be put to good use for either decorative or functional lighting with minimum circuitry.
It also shows a way to test whether a small cell has active protection.
Note that the short-circuit test resistors get hot quickly if there is no protection circuitry or the cell is rated for very high current. They should only be applied very briefly.
It's quite a neat way to add a bit of extra self-contained decorative lighting to your workshop or home that will stay lit in the event of power failure. If the battery is made waterproof with a plastic bag or other cover then this technique can also be used to add lighting to small plants/trees outdoors.
As always with lithium cells, make sure they are protected from physical damage and don't show signs of previous damage like significant sharp dents or puncturing.
The best way to render a lithium cell safe is to discharge it to 3V or less when there is little energy left to cause fiery incidents.
The charging modules shown are intended for traditional lithium ion cells with an upper voltage of around 4.2V (average voltage 3.7V) and are not suitable for LiFePO4 type cells that have an upper voltage of 3.6V (average voltage 3.3V) unless they have their own protection circuitry to cut off the charge at full capacity.
The lithium content calculation was based on roughly 0.3g of lithium per 1000mAh original capacity of a rechargeable cell. An equivalent non-rechargeable cell uses more lithium than one that can be recharged hundreds of times, but crams about four times the capacity in the same space.
In hindsight, maybe the title of this video should be "Inventing ways to use my stash of lithium cells."

    Back in the 60s we were doing something like that with a plastic soda staw, and rtv caulking. Minus the heat shrink, and it was for automotive applications. We would slip a 2 or 3 inch piece of soda staw over one wire, solder the other wires to the first wire, and slide the straw over the connection, and squirt the rtv into the straw. In a wet environment it was the way to go. At least,, we didn't have any problems. ..

It gave me enough know how and confidence to try things myself and I wanted to thank you for that :)

    As someone who's been thinking about getting back into hobbyist electronics for the first time since I was about 12, these videos have been an absolute goldmine for simple, useful tips and bucketloads of information, free of the oft-seen "you need £200 worth of tools & equipment before you even start" gatekeeping of hobbies like these. Like here, strengthening (and I suppose insulating too) bare leads using nothing but a hot glue gun and some heatshrink! Simple but brilliant. Thanks for your work & expertise in putting these together in a way that even an idiot like me can understand. And if you happen to be reading comments on this old video, I must ask where you get your equipment from, particularly those micro molex connectors? The only places I can find sell a single pair for about £2, or a million pairs for £20. Either way, a bit of an investment for a single project that I might give up on halfway through! :)

    I love the TP4056 modules. I converted pretty much all my LED flashlights (and the vintage ones that weren't originally LED got an upgrade) to use lithium cells using those modules to have built-in charging capability. It takes only a couple of minutes to set everything up and I've got quite good at embedding the circuit inside the device. Another fun thing is to restuff alkaline batteries (like the 6V lantern battery or the 4.5V flat square ones) with the lithium cell and circuit to make a completely invisible and reversible mod.

    I have a set of 100 warm white lights. They were powered off three AA cells and a flasher circuit. Funny thing was the circuit boosted the voltage to something like 24V and toggled the polarity for the effects. I eventually replaced the controller with a small 24V transformer and a 27K resistor. The lights now take about 0.3mA and something like 7mW for the lot. At night they still give enough light for me not to walk into things in the room whilst still enabling me to see the stars through the windows! It is impressive how efficient LEDs are these days, I remember my first ones in the early 1970s, 10mA and you could see red LEDs if the room wasn't brightly lit :-)

    Nice. I have a few old Lithium cells lying about. On a similar note I recently resurrected some old hair clippers where the 3xAA NiCd battery pack had died. I replaced the innards of the charger with a crap USB 5V PSU and rehacked the clippers to use a 18500 Lithium cell with one of those charger/protection circuits you used. They work brilliantly now. Charge very quickly and last for ages per charge and a bit lighter too. The charger weighs almost nothing compared to the big old transformer that used to be in it. I now use the clippers to trim by little beard one a week :)

    And if you buy a BL-5C type battery for a device and it's too thick, you need the thinner BL-4C instead. For actual, genuine nokia batteries the BL-5C would be 1020mAh and the BL-4C 720mAh. The fakes/knockoffs usually claim completely ridiculous capacities (I've seen anything from 1500-2900mAh for a BL-5C, which isn't possible in that physical size) and are actually far below the original batteries' rated capacities (usually 500-800mAh for an okay-ish BL-5C clone, less for really crappy ones)

    Something I do with those two-cell Christmas light strings: I make a "Joule Thief" circuit and mount it in the space which was supposed to be occupied by one of the two cells, then I run the light string from a single cell in the remaining space of the battery compartment. The single cell lasts about the same time as the two cells, but the string of LEDs drains the power fast regardless of whether you use it in the original configuration or with a joule thief circuit. BTW, old CFL lamps are a great source for transformer cores to use to make the joule thief circuit. They each have a toroid and a straight inductor, and both of them can be used. The wire from the straight inductor can be unwound and re-used to make the coils for your joule thief circuits, with plenty of wire left over.

    I've said it once and I'll say it again, I would love to have a video consisting of your life from leaving school onwards, I'm fascinated as to how knowledgeable you are with electronics and a vast array of other stuff. It's a complicated subject yet somehow you break it down into plain English, or Scottish in your case. You must have left school with some decent exam results to enable you to embark on the career you chose. So how about a Story of BC After School?? 😁😁

    To release those connectors from the shell you can use a 180g-Force Pogo Pin - the spring takes up some of the pressure and limits the damage to the connector retention tab as you press on it. Snip the tip off a spear-shape probe with a side cutter - a real one, not one for tiny component leads, the cheap component snips are too soft) and it won't skid as much on the tab

    Hola nunca fui a la escuela de electrónica, siempre me a fascinado el tema, hago pequeños proyectos con Arduino .Ahora reciclo una batería de teléfono, con un TP 4056 y alcanza los 4.30 volts no apaga el led rojo (cargando) y por lógica no enciende el azul (cargado) busque todo el día como reducir la histéresis entre encendido y apagado, pensando en voltaje. A pesar de no comprender con precisión tu explicación, veo que la histéresis entre encendido y apagado es controlada por corriente, (i) voy a quitar la resistencia de 1k y pondré un trimpot, espero conseguir cambios en la histéresis, desde hace tiempo eres una de mis profesores favoritos de electrónica nunca me di el valor de hacer comentarios.

    Maybe I misunderstood you when you talked about one MOS being energized for charging and the other for discharging, but I think you misspoke (don't take me wrong, I'm your fan and I think your channel is great! ) I once worked a bit on a power management unit (PMU) and I believe I know why they use 2 MOS. The use of 2 NMOS is because of the diodes which are shown in the schematic, called body diodes, and that are intrinsic/parasitic to the transistor itself (that's why they are in dashed lines) . By having 2 MOS you end up with 2 back to back diodes which can not conduct in a faulty condition. That is the purpose of the 2 NMOS, despite making the MOS resistance 2x worse and doubling the cost (in MOS at least). For instance, imagine you don't have M1. If BATT+ gets accidentally shorted to BATT-, even if the chip detects it (it should) and turns OFF M2, current will still flow through its body diode and the chip would not have control and be able to protect the battery. Inserting M1 fixes that. Likewise, w/o M2, if someone accidentally tries to overcharge the battery, even if M1 is turned OFF current will still flow through its body diode. You'll need M2 to cut it off. Sure you can use the parasitic diodes path on charge/discharge cycles, but that would lead right away to a drop of 0.7V on the battery voltage and to a loss of efficiency. The MOS resistance is much smaller and the diodes were never intended to be used as charging or discharging devices. Both NMOS are therefore turned ON either when charging or discharging. Of course I might be wrong, but it's too late and I'm too lazy to go check the DW01-P datasheet right now 😊 Cheers.

    I think you're right. You can't have significant current through either gate, nor through the current sense pin on the chip. Rub those out and you're left with no path on the negative side if either mosfet is off. It has to go through both mosfets in either direction.

    Them little TP4056 boards are handy, I've converted a number of things from Alkaline battery to Lithium batteries using these boards, just have to make sure to replace the charge current resistor to match the cell, otherwise it can pump too much current into the cell, which the protection will stop, but still better to be safe... :)

    This is actually pretty awesome, i have done this myself, but not with these kinds of batteries. I took a large retro looking lamp, with those big round glass tops and i have put an old color changing LED setup only in the glass part. So Basically its a big glowing ball when i put it on the floor with the light inside it. The LED changes colors slowly out of one single LED and with the diffusing of the lamps spherical dome that sits by itself on the floor, as if some kind of colored crystal ball, its a nice nightlight for ambiance. I will convert to these batteries next and i like the connector idea of it as well. :)

    I've got a bathroom scale that talks. Well it used to talk. It kept coming on at random times without provocation and any time someone made any noise near it. It'd be 4 AM, I'd be sleeping away and... "PLEASE WAIT" "PLEASE STEP ON THE SCALE" So I did what any self respecting person would do, and put a drill bit through the speaker at 10,000RPM. It no longer talks. Then the battery tray (double AAA), kept falling out. Couldn't put the scale down or get on it without the batteries falling out. So I chopped it off, stuck it on the bench supply, and found it didn't make magic smoke at 4.2V rather than 3V. Ended up sticking a 1500mah cell on it from a drone battery that had exploded on me. Hot glued a magnet to the scale and to the battery, and now it's a very convenient rechargeable scale. It still comes on randomly and the screen lights for 20 seconds each time, but even after months that battery is still sitting at 4V. It's quite impressive how long low load stuff can go on a simple lithium cell.

    I always used a similar manual stripper to Clive's, except mine was much worse made in quality. Its jaws were straight and didn't connect very well and it didn't cut very well and it was a chore to adjust, and due to bad alignment, and visibility, the amount of covering removed tended to be pretty random. I tried a few automatic ones at a store. They do tend to not work on thinner cables, but there are expensive ones that can. I watched a video by Andreas Spiess about wire strippers and chose the big clunky Chinese black plastic one, the FS-D3, ordered it for about 6€, it took about 3 months, and surprise, it actually works amazingly well for super thin wires and even for ribbon cables.

    at 23:17, your showing how the protection circuit works reminded me a lot of quassi connectivity (also known as a BUD switch, or block update detector switch) for redstone in Minecraft, where the only way you can get the component to update is to make some sort of change in the circuit, most times near the power source, or component being powered. I find there are a lot of similarities between electrical circuits and redstone, but this is the first time I've seen something that reminds me of the oddity of quassi connectivity, especially in a protection circuit. Quite interesting!

Think it would be possible to come up with a simple "personal heater" that could be made out of materials scavenged and plugged into USB or even just like a modded dollar store light or aa,aaa cells? Maybe 2 items from the dollar store combined makes a pocket heater? Something that simple that's accessible could save lives. cheers brother
