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. ..
If you also watch Julian Ilett's channel, you can see that his production of the outdoor solar controllers he makes/sells/used to sell have a similar construction, hot melt glue under heatshrink.
I just wanted to say thank you, I have learned so much with you. The technical stuff of course (very enjoyable) but as well as the basic trivial things no one is truly explaining such as soldering tips and tricks, cutting things the right length, using crimping tools ,terminating wires or just good/safe practices/habits to have and so much more of the little things in a very entertaining but skillful and understandable way. 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! :)
7:10 Posssbly the BL-5C which of course comes from old Nokia phones, but now pleasantly makes an appearance in modern portable radios such as the Retekess V115 and the Retevis RB615.
On my bassy laptop (with headphones and/or inbuilt speakers) and TV I can, but they can stream at 4k (not that the videos are uploaded at 4k), so wonder if they are able to decompress more effectively, as never heard on my iPad (with same decent headphones or inbuilt speakers).
Did something similar with some old phone cells (motivated by previous projects of yours), used them to power a slow cycling RGB LED, in such a configuration that it can be charged while the light is still on, one could conceivably do that with these quite easily, just add a second connector on the battery without a resistor. For some of us IT guys, its all about uptime!
Love the simple explanation on how to calculate the amperage and the little adapter is a nice touch. I like the fact that you can still see the resistor value. Awesome video.
Perfect timing. Just like you I bought one of those Halloween Strobe lights with the nice housing on clearance and my plan is exactly this right down to the charger board. Ok back to watching.
Clive! Icon of freelance electronic technology implementation! I watch on 50 inch tvs as monitors and listen through workshop HI=FI receiver and have never heard your soldering station buzzing. Love your videos and view them promptly. Kudos!
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.
Hey thanks for sharing your experience. It would be really cool to watch a video of you retrofitting a 6V battery with lithium cells, I'd click on that in a second.
you show the safe application in electrical circuits, it is nice to see the methods and explanation of how things safely work together. plus the use of the connections for easy applications with universal connections and various resistors. along with changing set up for the battery.nice video
Love the thumb and index holding the wires and the middle and ring holding the solder. Not your 1st time doing that I guess 😉. I'll have to try that. Its always a dance with alligator clips over here.
I didn't even realise I soldered like that until people pointed it out. It also explains why people would ask me if I wanted them to hold stuff while I did repairs and then suddenly went silent when I started using my left hand to hold the PCB, hold the component in position and feed solder in simultaneously.
When I see Bigclive doing it, it looks amazing and difficult, but I've caught myself doing it too. Hands are amazing. Good to see you also watch Bigclive.
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)
i cant hear the soldering iron, or the noise from my desktop computer is outbuzzing it, heh. Or its my damaged hearing :-) Very neat project, need to look into it and see if i got some leds laying about, might have my old samsung s4 4000ish mah battery somewhere... or a old powerbank to salvage!
I use these cells to build little night lights to guide you the way. I found out they give me enough light when i run the led with 0.1mA or even less. One 18650 liion cells will last for 2-3 years. Self discharge will be higher than the actual current of the led. I just use smd 5630 leds from 5m strips with a 10k resistor in series.
I just realised my day wouldn't feel the same if i didn't get to hear your voice, doesn't even matter which video that is i have probably autoplayed everything by now.
Hey Clive, I'd suggest looking into graphene supercaps. You might find them interesting for how small they are compared to traditional supercaps(which are of course humongous.)
I don't think they've come of age yet. There's also the issue that if a graphene supercapacitor can be charged in seconds then it can also unleash all its energy in seconds too. I wonder what the failure mode is.
I've ordered 3 sets of crimpers off Amazon with overwhelming positive reviews. All garbage! Is there a direct link to the good ones? Searching, and wondering if the reviews are legit or a scam is getting tiresome.
Thank you for that reminder about measuring voltage drop across the resistor you know the value of to determine Amp draw. I appreciate you sir. You are very easy to follow and learn from.
Funny that I decided to use an LG phone battery as I began to watch this. It's been a few years since it got charged and still lighted up my LED tester. Having small LEDs and wires nearby opened up some exploration for me recently. Your videos are helping me with some circuits I wanted to make.
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
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 :-)
I should have sent my AvE ruler to you for assembly i managed to fudge it right up somehow. Also what should I look for if I want one of those crimper things?
Bill’s Tool Store in the Glasga Barras is my go-to place for impossible to find stuff. Best visited often, buy on impulse and keep for when may be needed. I really must build another shed. Staff know a lot of stuff too. As usual Clive, both entertaining and educative. Shame a lot of teachers don’t understand the need for both.
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 :)
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. Saludos desde Queretaro MX
Puede haber alguna variación entre los módulos TP4056. Podría valer la pena probar con otro. Muchos de ellos disminuyen mucho la velocidad cuando la celda está casi llena.
@@bigclivedotcom Obviously there will be things to overcome, but from what I've seen so far (and it's early days for me at least) it seems to be promising, if for no other reason than not having to carry small bombs around with me all the time. To be fair this is coming from 'proper' sources so I am rather more enthused than with the usual nonsense lol
Clive, the Uni-T meter becomes a lot easier to use if you put a little dot of white paint in the indicator dimple on the dial switch. Try it and see if it helps you. I've applied this to other meters too. Cheers, mate!
I like to fold over the end of the kapton tape on itself so it's easy to grab next time I use it but most of the time it gets away and sticks down to the roll.
Dear Clive, I have a Moto G5 and love it as an all round mobile. Batteries are less than £10 and you just open the back and fit them yourself, 30 seconds. I have to say the new G8 does look good, large battery, good camera/cheap storage you fit yourself, but sealed back, Cheers Colin.
@@johnrehwinkel7241 That's probably why a lot of products that need a battery with low self discharge like clocks tend to use alkaline batteries instead of the more expensive lithium primary ones.
If you mean the tool used for the crimps, it came from a UK supplier called Rapid Electronics. www.rapidonline.com/rvfm-ht-225d-ratchet-action-crimp-tool-ht225d-85-0262
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. :)
Speaking of thoes crimping tools, I have on occasion had to use a pair of pliers in their stead, and yes they are very much worth every last penny for the correct tool.
Vidar Odinson good luck,I’ve built loads of charging projects using this little board. Mainly for 18650 cells.Used them literally for hundreds of charges & I lost one tp board out of 10
Love it Clive, would like to see you try a little light from the side where your wrists are, just to get rid of some of the shadows, only needs a little bit.
@@bigclivedotcom Body heat. You are a disruption to the natural flow of air in the room so the heat rising from your body causes air currents to move toward you. It's quite an annoyance to me but perhaps the suggestion of the light bulb is a good one. I'll have to try that.
I have been using the TP4065 modules for ages now. Make sure to get the ones with protection built in to make sure shorts are protected. Lately I have been trying to implement the version with adjustable output which works well, until you want to fix the pot. It always seems to shift a bit.
DW01 current trip - how do these DW01 chips set the current trip level - since the sense resistor is the 'on' resistance of two MOSFETs - which could vary with the size/type of the MOSFETs used ? Oh, have I just answered my own q. ? I think I have.... Thanks Clive.
I've had a long look on eBay for those molex style connectors over the years and never found cheap knockoffs. I'm stuck with cpc . What should I be searching for? Love the tip on the hot melt glue.
The wire strippers you use are the same type as my preferred ones, I think I acquired them from a careless engineer at my factory, these are basic but consistent when stripping many wires. Great tool from great careless engineer.
Was wondering. With a, for instance, 4S 5P BMS, can I use it as a 4S 3P then add the other batteries later? Or does the BMS need to be fully populated??? Thank you.
If it's for four groups of parallel cells in series then it should be OK for smaller parallel groups as long as the charging current is within their range.
I tend to melt insulation off cables instead of using strippers if my shitty iron is on. I have several irons on the bench, one always reserved for dirty work like melting insulation and plastic welding. (I have good exterior-vented fume extraction and I can't even spell carsinojinns. )
@@Dlck.C.Normous The lead is not really in the fumes and the flux, that does vaporize, for lead-free solder is apparently more aggressive, so you might want to check more reliable sources than my YT comment before committing :P
How do you balance charge each cell? My batteries have an extra wire per cell so I’d have a 3 pin plug for a two cell and a 4 pin plug for a 3 cell and so on
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?? 😁😁
Short summary. Bottom of the class at school. Straight into an apprenticeship with an electrical engineering company. Then just absorbing huge quantities of electrical and electronic data throughout my life.
@@bigclivedotcom Just goes to show formal education isn't everything. Learning on the job and building experience as you go (good and bad) leads to a better engineer.
Not sure that would be a good idea, as Li packs are designed to get cut off to protect the battery, the joule thief is designed to remove the very last vestiges of a battery's voltage. But I could be wrong?
You can get protection circuits that will protect against a short circuit or over-discharge. Otherwise, if the wire is being used as a heater and is passing current within the rating of the cell it should be OK.
@@bigclivedotcom The wire is being used to heat, thanks for responding.

How do you know if a mains usb plug has a battery limiting function? I ask because my wife bought a desk top led reading lamp and she read the instructions. It said do not over charge as it can catch fire. Now you get intelligent plugs for charging mobile phones but mobile phones have battery protection built in. What plug should I use?
They often include that "unplug when charged" thing as a liability thing. Although I've come across cheap eBay desk lights that did overcharge their unprotected cell.
Id assume most of its PVC. PTFE/TFE are nice insulations as well, but as with silicone, they get quite expensive compared to common PVC insulated wire, and harder to find.
I got a crimper off aliexpress which does really good crimps for molex and jst, though the dial that is supposed to adjust the pressure fell off, dupont crimps need 2 goes as they are really long.
iirc lithium primaries have way more lithium in them than the rechargeable ones, they also have better energy density and can be stored for 10-30 years before self discharge kills them

Bill’s Tool Store in the Glasga Barras is my go-to place for impossible to find stuff. Best visited often, buy on impulse and keep for when may be needed. I really must build another shed. Staff know a lot of stuff too. As usual Clive, both entertaining and educative. Shame a lot of teachers don’t understand the need for both.
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 :)
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. Saludos desde Queretaro MX
Puede haber alguna variación entre los módulos TP4056. Podría valer la pena probar con otro.
Muchos de ellos disminuyen mucho la velocidad cuando la celda está casi llena.
You make it look so easy! I'm very glad I found your videos as I want to make a system to light up all my dioramas/doll houses.
Nice calculator Clive.
Very timely with Xmas approaching. Thanks
24:00 - "If, however, you have a big, *_fat_* battery pack..." How rude! It's not fat...it's just got big atoms. ;) lol
It was a penis reference
Is there a great reason for little stuff like this to be using kapton tape instead of regular vinyl electrical tape?
Electrical isolation properties & great for vast temp ranges mate
It doesn't melt or catch fire as easily. It's just a bit safer.
@@MickeyD2012 but realistically, in these sorts of uses probably either is sufficient?
@@gd.ritter It's better than hanging on to it.
Hey Clive - what do you think of 'solid state' battery technology ?
I'll believe it when I see it being manufactured.
@@bigclivedotcom Obviously there will be things to overcome, but from what I've seen so far (and it's early days for me at least) it seems to be promising, if for no other reason than not having to carry small bombs around with me all the time. To be fair this is coming from 'proper' sources so I am rather more enthused than with the usual nonsense lol
have you considered a phone camera lense kit for more control . . ?
I've tried some, but not found them useful so far.
Clive, the Uni-T meter becomes a lot easier to use if you put a little dot of white paint in the indicator dimple on the dial switch. Try it and see if it helps you. I've applied this to other meters too. Cheers, mate!
Who are you? The next unabomber?
Sorry, can't hear the soldering iron over my server and networking gears insanely loud fans for some strange reason.........
Excellent little project very useful indeed! Thanks Clive!🙏
hot glue and shrink tube technique is on point! and very pleasing when the clear tubing is used.
definitely stealing this idea.
I like to fold over the end of the kapton tape on itself so it's easy to grab next time I use it but most of the time it gets away and sticks down to the roll.
I do that too.
So what happens if you use that little male-male connector to plug two batteries into each other?
The cell voltages will gradually equalise with the current limited by the resistors.
Dear Clive, I have a Moto G5 and love it as an all round mobile. Batteries are less than £10 and you just open the back and fit them yourself, 30 seconds. I have to say the new G8 does look good, large battery, good camera/cheap storage you fit yourself, but sealed back, Cheers Colin.
12:07 The advantages of primary lithium cells are higher specific energy, higher energy density and lower self discharge.
As it happens, they also contain much more lithium than an equivalent capacity rechargeable cell.
@@johnrehwinkel7241 That's probably why a lot of products that need a battery with low self discharge like clocks tend to use alkaline batteries instead of the more expensive lithium primary ones.
Clive, have you any idea what make the terminal crimps you used in this video, as they seem to be very good.
If you mean the tool used for the crimps, it came from a UK supplier called Rapid Electronics.
www.rapidonline.com/rvfm-ht-225d-ratchet-action-crimp-tool-ht225d-85-0262
You beautiful man you are literally carrying my project with these well made videos.
What are you making besides a firehazard?
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. :)
Speaking of thoes crimping tools, I have on occasion had to use a pair of pliers in their stead, and yes they are very much worth every last penny for the correct tool.
That linking connection is a great idea.
Great video! Is there a way to add indication for when the cells are done charging through that little module?
The module lights up blue I think when the cells are charged if I remember correctly.
I’m sure there is definitely an led indicator on the TP pcb’s
@@Error-hv4on Excellent, thanks a lot. Time to hunt for modules!
Vidar Odinson good luck,I’ve built loads of charging projects using this little board.
Mainly for 18650 cells.Used them literally for hundreds of charges & I lost one tp board out of 10
Love it Clive, would like to see you try a little light from the side where your wrists are, just to get rid of some of the shadows, only needs a little bit.
Clive, Have you ever noticed that the fumes always go toward toward you when melting the solder?
Similarly, street lights always flicker (or go out) when you are walking directly beneath them. Spooky stuff.
The fumes go towards heat. If you put on a light bulb near your soldering the smoke will go to it when lit.
@@davestech6357 But the soldering iron is the hottest thing in the area yet the fumes move away from it.
I've sometimes pondered if it's an electrostatic effect or rising body heat that drags the vapour towards me.
@@bigclivedotcom Body heat. You are a disruption to the natural flow of air in the room so the heat rising from your body causes air currents to move toward you. It's quite an annoyance to me but perhaps the suggestion of the light bulb is a good one. I'll have to try that.
I have been using the TP4065 modules for ages now. Make sure to get the ones with protection built in to make sure shorts are protected. Lately I have been trying to implement the version with adjustable output which works well, until you want to fix the pot. It always seems to shift a bit.
DW01 current trip - how do these DW01 chips set the current trip level - since the sense resistor is the 'on' resistance of two MOSFETs - which could vary with the size/type of the MOSFETs used ? Oh, have I just answered my own q. ? I think I have.... Thanks Clive.
It depends on the on-state resistance of the MOSFETs. The bigger MOSFETs won't reach the threshold trip voltage until the current is much higher.
@@bigclivedotcom Yeah, I did answer my own question then - thanks for confirming my thoughts Clive.
I've had a long look on eBay for those molex style connectors over the years and never found cheap knockoffs. I'm stuck with cpc . What should I be searching for? Love the tip on the hot melt glue.
The keyword appears to be KF2510
www.ebay.co.uk/itm/254238509468
Excellent. Thank you so much.
Your videos are wonderful Clive, I enjoy every one...... Thank You.
None of us can hear that soldering iron, Clive ... but it is nice to imagine we could ... go on, tell us another one
The wire strippers you use are the same type as my preferred ones, I think I acquired them from a careless engineer at my factory, these are basic but consistent when stripping many wires. Great tool from great careless engineer.
Aside from heat resistance, what advantage does Kapton tape have over heavy duty clear packing tape (the thick stuff)?
It's primarily heat resistance and insulation characteristic.
It's the only tape endorsed by Jarel
What an amazing video! Loved the whole video!
Was wondering. With a, for instance, 4S 5P BMS, can I use it as a 4S 3P then add the other batteries later? Or does the BMS need to be fully populated??? Thank you.
If it's for four groups of parallel cells in series then it should be OK for smaller parallel groups as long as the charging current is within their range.
do you need to worry about changing the charge current resistor on the non-DWO1 tp4056 units?
Only for very small cells.
thanks!
I tend to melt insulation off cables instead of using strippers if my shitty iron is on. I have several irons on the bench, one always reserved for dirty work like melting insulation and plastic welding.
(I have good exterior-vented fume extraction and I can't even spell carsinojinns. )
I might have to switch over to the lead free stuff, I've no fume extraction setup and I can hardly do basic arrhythmic anymore.
@@Dlck.C.Normous The lead is not really in the fumes and the flux, that does vaporize, for lead-free solder is apparently more aggressive, so you might want to check more reliable sources than my YT comment before committing :P
That's because you sir are an idiot. Like vRobert
Can the tp4056 be used with a 6v solar panel instead of the USB port?
How do you balance charge each cell? My batteries have an extra wire per cell so I’d have a 3 pin plug for a two cell and a 4 pin plug for a 3 cell and so on
These are just single cells. The double one has them in parallel so they act as a single cell.
can we get a teardown of that pink calculator and link to the item for purchase?
It came from a Poundland in Edinburgh. I've not seen them anywhere else.
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?? 😁😁
Short summary. Bottom of the class at school. Straight into an apprenticeship with an electrical engineering company. Then just absorbing huge quantities of electrical and electronic data throughout my life.
@@bigclivedotcom Just goes to show formal education isn't everything. Learning on the job and building experience as you go (good and bad) leads to a better engineer.
Get a life baby
I'm just curious, is there a particular reason people seem to always use kapton tape on batteries and not something like hot glue?
Kapton tape is tough and heat resistant.
The strippers are quite hard to get. Amazon had them, but now it says, unavailable. Don't know when or if they will be back in stock.
I heard you can charge the button cells at low current but lose 10 percent each time something like that.
Clive, I have been wondering about a Li+ Joule Thief...Would this be something you (the designer of the Joule Thief) would be willing to tackle?
Not sure that would be a good idea, as Li packs are designed to get cut off to protect the battery, the joule thief is designed to remove the very last vestiges of a battery's voltage. But I could be wrong?
The Joule Thief is really designed for low voltage like 1.5V or less. Anything higher will just flow directly through the LED.
When using lithium batteries with nichrome wire which shorts the battery is there protection that can be added or is it required?
You can get protection circuits that will protect against a short circuit or over-discharge. Otherwise, if the wire is being used as a heater and is passing current within the rating of the cell it should be OK.
@@bigclivedotcom The wire is being used to heat, thanks for responding.
How do you know if a mains usb plug has a battery limiting function? I ask because my wife bought a desk top led reading lamp and she read the instructions. It said do not over charge as it can catch fire. Now you get intelligent plugs for charging mobile phones but mobile phones have battery protection built in. What plug should I use?
They often include that "unplug when charged" thing as a liability thing. Although I've come across cheap eBay desk lights that did overcharge their unprotected cell.
At the start, is that your phone's zoom, or did you just move it?
Re melting insulation, do you use silicone insulated wire?
Id assume most of its PVC. PTFE/TFE are nice insulations as well, but as with silicone, they get quite expensive compared to common PVC insulated wire, and harder to find.
Who gives a f...?
I got a crimper off aliexpress which does really good crimps for molex and jst, though the dial that is supposed to adjust the pressure fell off, dupont crimps need 2 goes as they are really long.
iirc lithium primaries have way more lithium in them than the rechargeable ones, they also have better energy density and can be stored for 10-30 years before self discharge kills them
@Andrew_koala You just pretty much defined "self-discharge."
