The 4056 needs an input between 4.5 and 5.5 volts. If you only have 3 volts , you could solve with a DC-DC step-up regulator. To drive a led properly, more than the voltage or wattage, you should consider the current... I think that with a good battery and a good led driver you will be able to make it work without problems!

In truth, I am a robot

Thank you very much dear! Feel free to write me for anything!

Thanks a lot man! Where are you from?

What is a keyfob? Good question. I suggest you check the device datasheet before connecting a battery with a higher voltage. If you don't have a datasheet or professional test tools, ask the seller or manufacturer...

Nice to meet you and thanks for all the nice words! I think diodegonewild is Czech.... Unfortunately I am Italian. I think you are the right person to be my English teacher...

Would you like to be my English teacher?

​@@dariocoseI can probably teach you English bro

@@Salador1777 ahahahhaha thanks a lot bro but my English really sucks ✊

Because I am Italian, we Italians do everything in the kitchen and with kitchen gloves!

I think you just need an adjustable voltage battery charger

Hahahahhahaha. I feel the same way. You are a cool!

@@dariocose Feels like a Roblox meme video 😂

@@4bSix86f61 I don't know this stuff. Links please

I definitely will!

This is the best most tolerable voice they can choose imo. And good video content. Good job.

I learned something new today! Thank you very much

Is the translation of your comment "Heroic overcoming of difficulties that he created for himself"? 🤣💪🤣💪🤣💪🤣💪 Thanks so much for support

You are right. The next one will be made of wood 🪵🪚🌈🦄🎉

I promise I'll try it soon

@@dariocose then ill subscribe to hear that

😂😂😂 🌈🦄🙏

Thanks so much for your support and your kind words!

He probably a reason. The video was clear and incredibly easy to follow, which might not be the case if he used his real voice 🤷. This clearly isn't scam content, although I agree that even a strong accent is better than an AI voice...

I am setting up to improve the voice-over in my videos... All I need is a good microphone and some courage 🙂

@@dariocose you got this :) everyone’s a bit nervous at the start, but stick with it

@@semaja2 ❤

If you're really concerned about your accent. There are far better robot voices you could use....

Depends on the voltage... You can use the formula Ampere = Watt/Volt

Hi @lofirhythm5379. Thank you for your comment. I am very happy that you like my videos! I think the circuit of these cheap lights is not powerful enough to drive a 1 watt led. I think in the next videos I will talk about LED drivers that allow more powerful LEDs to be used .... Thanks again for your support, and if you have any more questions, don't hesitate to write to me!

You are right. Serious cyclists (like me and I assume you! :D) have more powerful and durable equipment! Modern bike lights have power that is incomparable to those cr4ppy little lights, and of course they are rechargeable! Although I feel like an organized cyclist, the fact is that I had a drawer full of this stuff and decided to make a video of it!

The LED receives the input voltage minus a small voltage drop. There is a detailed table on the datasheet. However, the cn5711 drives the LED in current, not in voltage.

hello. I quickly checked with a cheap oscilloscope and noticed that by increasing the voltage the frequency of the signal on the led drops until it stops oscillating at about 1.3v. At 0.6v the frequency is 130KHZ Vmax 3.44v Vmin -0.8v

first of all, the cn5711 works up to 6 volts. i would not use 7 volts to power it. you can power it with any voltage you want between 2.8 and 6v, you just have to check that the led supply current is right. If you want you can use an appropriate resistor between the driver and the led to further adjust the current

The answer is you can but it will take a long long time, and putting a heat sink is also advisable. If you don't have heat sink than use two modules in parallel to charge the battery. Edit:Remember to do parallel connection of charging terminals, output terminals and battery terminals.

@@azharmukhi5894 thanks for the tip

Hello dear, thanks for the advice! I hope the audio of my videos will be broadcast in all the elevators in the world 😂😂😂 If you prefer, in the video description there is a link to the fully textual guide (instructables). Thanks for the support!

They expire fast.

You are right. The tp4056 should only be used for a single battery

You absolutely can connect multiple cells in parallel. The charger can not tell the difference between five 500Ah cells in parallel or one 2500mAh cell. In fact, the cells could even be different capacities because the parallel connection forces the same voltage across all connected cells throughout the charge process. I think you may be confusing cell capacity with charge current. You can charge a 3400mAh cell with 100mA of current safely, it will just take a long time. (+34h)

I read a few articles. I don't think you can use the same charger for lir and ml. "They have completely different chemistries so they have completely different charging voltages and profiles." - electronics.stackexchange.com/questions/533265/protection-and-charging-circuit-for-lir2032-or-ml2032-battery - www.reddit.com/r/dreamcast/comments/g1atiq/lir2032_vs_ml2032/ you can try a charger like s.click.aliexpress.com/e/_DkRpijx or this circuit seems suitable and adjustable in voltage and current s.click.aliexpress.com/e/_Dne8NMD

LIr 2032 have higher voltage, but you can add a diode in series on output + terminal for drop the V. and charge ML2032 ?

My friend, I am Italian and I have a terrible accent. Believe me, the robot voice is a better option!

Of course! I need some time to study and do some tests and I will make your video! Thank you so much for your support!

@@dariocose To know how to set these resistors is most important to me, because i want to connect a NTC to a different IC (IP2368 Battery charge controller with USB PD) of mine, too. It's datasheet mentioned only the usage of a 10k NTC and i need to connect a 100k NTC but have no Idea how to do that. Another IPxxx IC also has these 2 resistors, which seem to be included to tune the Chip for the resistance of the NTC. If you can tell me, how to calculate these values, i could finish my current project even before watching your video which of course had to be created first and could not help me with my question in the end. But i will watch it in any case :-)

Thank you, grazie mille! 🙏

wowwowwowwowwow

🙏🤟🦄🌱🚀

I use a 47k resistor, so the charging current is lowered to about 30mah

@@dariocose so basically the less mah the higher the resistor? My second question is why did you solder the resistor to the pin? As it has two pins cant you directly put in the jumper?

@@Mehhh_was_here hi. 1) in the datasheet of tp4056 (or in this video kzfaq.info/get/bejne/q8ecf9qKt7isZo0.html ) there are the tables and formula for choosing the right resistor. In general, the higher the resistance, the lower the charging current. 2) I have no idea why I soldered the resistor on the pins 😁
