How do I get a dropout voltage of 3.3v from the charger module?

Me no speak Japanese!

Congrats for the video. I have a question, I don't understand in which phase the battery charging takes place.

I have a quite pro device doing the same when it's on in a charging dock. It happens because the load is using higher than the battery charging can catch up to. Charging is much less in general for safety. One can make a project sleep to some degree or crank it up. I don't know if it's relevant in this video. I still learn something. The funny thing is that I didn't expect to learn so much and be forced into caring about power delivery from batteries. It could be easier, but we jumped into those DIY subjects ourselves.

This video is completely wrong

1:28

Thanks for sharing. Very helpful

By coding with Atiny; I think it requires logic integrated circuits, but without that, can we take the voltage value with an integrated coded in Atiny and tell it to supply it according to percentage values? This is a 4056 integrated circuit, I thought it cut off automatically, maybe I'm wrong?

Addressing the comments with people saying using a solar panel with TP4056 will not be a problem: 1. I would like them to take some time and read the links I have added in the description section saying the exact same thing I am saying in the video. I would have accepted I am wrong, "IF" I was the only one saying that. There are a lot of people saying the same thing in the internet. 2. Something bad didn't happen to your circuit doesn't mean it is safe, or it will never happen. You might get away with using that unsafe circuit and not have a problem in your lifetime, but it is also possible that the conditions are not in your favor just once, and you had a serious issue with your circuit. 3. It can never hurt to be extra safe, especially when working with Li-Ion cells. 4. As one comment is suggesting, I WILL NOT TAKE DOWN THE VIDEO. Even if the circuit for using solar panel with Li-Ion cells is not useful, load sharing is a very useful circuit. Just read the applications of this circuit and you would see what I mean. One example is your laptop, when you battery is completely charged, the laptop is completely running using the power from the charger and not the battery. Even when you remove the charger, it doesn't turn off but runs off of battery. How is that happening? Load sharing! No one knows the effort that goes behind making even a simple RUclips video until you do it. So please don't just come of the blue and ask me to take down the video. Thanks!

I agree with the first guy you don't know what you're talking about it's the whole point of a protection to protect it from overcharging and undercharging you really need to rethink this video because I'm a novice and immediately knew you were wrong maybe you got a bad board from a careless manufacturer

Nice one, what about a fuse?

Thanks actually I gave 120 pixel strip 2 meter 60 each. Theoretically power consumption is 60*120 =7.2 amp. But IT SHOULD BE FINE AS I ONLY ABLE BUY 5 V 3 AMP ADAPTER 5.5 MM BARREL. NOT COMFORTABLE TO USE POWER SUPPLY. IN MARKET IT IS HARD TO FIND 5 V HIGH AMP ADAPTER. THOUGH I have multiple smart phone adapter rated 5 v 3.5 amp . They normally have multiple rating like 9 v 3 amp 5 v 4 amp etc. not sure the led strip controller sp621e smart enough to draw 5 v ones otherwise there is risk of destroying the LEDs strip. Also need USB to 5.5 mm dc cable. What do you suggest. Don't want to cut 2 m strip.

Please what the name of the bridge retifier i want to chek 5he datasheet

BigCliveDotCom says it's a myth: ruclips.net/video/f2yMs-JAyQM/видео.html

or..... you can buy a pt4056 with protection.

1:51 I think that the circuit shown here is not complete, unless of course the connected load can accept a wide voltage range: 3V...8V. I think that when the power bypasses the TP4056 board, there should be a decrease in voltage from 4.2V...8V, which can be supplied to the TP4056 board, to the maximum voltage at the output of the TP4056 board, namely 4.2V. In addition, I think that the circuit shown assumes that there is a stable power supply at the input and it may not work properly if it is powered from a solar panel.

1:06 Most likely, the mentioned problem does not exist at all - someone just made it up. If at the battery connection points, when the battery is not present, the open circuit voltage does not exceed 4.25V, then the described problem will not occur. The battery can be charged to a maximum of this voltage and no more.

To those thinking that load sharing is needed because of overcharge protection, it's not the reason. The reason to use load sharing is trickle charging. The out of tp4056 alwaus runs off battery and discharges it which triggers the charger module to recharge the battery which wastes charging cycles. Load sharing prevents that

This is incorrect. The TP4056 detects when the cell is almost fully charged and reduces the charge current to zero when it falls below 100ma. If any load is drawn, it supplies only the current drawn by that load keeping the charging voltage just under 4.2V. For example if the TP4056 charges a cell to 4.2V it will drop the charge current to zero. If you then attach a 200ma load, the TP4056 will supply only 200ma, powering the load but not overcharging the cell. This is all in the datasheets and you can verify it yourself easily enough.

Do not risk your life doing this project......its a Made in Indian DANGEROUS project !!

No - the TP4056 DOES have a charge protection and will never go beyond 4.2V so everyone is safe.

Incredible!

Great Job

How bout with minimal load like for cellphone charging, is it safe... 🤔

Please share schematic of all connection on the circuit board.

There is a fundamental error in this video, particularly the calculation at 1:38 into the video. The calculation for I=203/150K is written as 1.5mA This should be 1.53333 and explains why when the calculation is reversed as Vr = 150K * 1.5ma it gives a value of 225V. The rounding error off the end of the initial calculation is why you get a value of 5V difference and not because of any electrical issue. At that point, I'm afraid, the whole maths demonstration is worthless. Sorry to sound critical but it is important to be accurate.

yes ofc show esp32 repo for esp8266. Only money grab video

you are crazy man read the datasheet first

As I understand, the load keeps having power when we have sun, right? At what point, the solar panel will stop providing power straight into the load? for example since the solar panel starts providing less than 4V? so after that, the power to the load comes from the TP4056? this circuit is fine if we want to have our esp32 working while the sunshine is maximum?

Very detailed instructions, thanks. I have a question, is it possible to get the remote 5-digit code so I can program it in my universal RC? my tv is no-name Chinese tv and I can’t find the code anywhere, I even emailed the manufacturer for the code, but I did get a response.

great video, love what you're doing. Thanks to you I find a good explanation of mains sensing principles. Farewell !

using bms 1s 3 amp max is enough.

Нормально схему впадлу что ли показать.

I am mesmerized by the crookedness of the whole thing.

I don t think the 4056 will overcharge over 4.2V, but it will eventually keep it to 4.2 if the lod current is above the termination current. Not even sure if this circuits works correctly in the early morning with low battery level and weak solar panel current. This circuit is usually adopted for wall chargers with a solid 5V input

Hello, do you know any device or controller with speakers to use wled witouth soldering speakers? I want to use wled with music reactive option.

I have also made simler MP3 player The sound stops when the volume of the board increases

Hello i tried to do the same in Kicad but i've received some Errors and i don't know how to solve it It possible for you to do it in Kicad? or could you please give me tipps to solve the problem in Kicad?

This is nonsense. The TP4056 won't charge the cell above 4.2V. Doesn't matter that the rest of the circuit is drawing power - the power isn't going into the cell - it's going to the rest of the circuit. TP4056 will start charging when the cell voltage falls, and stop when it rises to 4.2V again. It's not going to overcharge the cell.

errors in your specifications not an accurate guide

That's cool ty.

This guy made a video not even reading TP4056 datasheet... Otherwise, he wouldn't be talking nonsense.

Good effort...👌👌

bro can you provide me this file for my esp8266

With apologies, as I'm sure this is a n00b question... What is the value of the pull up resistor.. 10k? Thanks for your information.... Super helpful! @Tesalex

Beautifully explained, especially considering all the information you gave us.

Excellent video, thank you.

Hey i didn't understand Y u can't directly connect the TP4056 without load sharing Cause TP4056 has over-voltage protection And the battery charging is separated from the output so it won't overcharge the batter
