[@subrotodebnath9346]

Your explanation about Over-Charge(OC) and Over-Discharge(OD) protection seems wrong. The 8205A is a pair of N-Channel Enhancement type MOSFET. The Drain of both MOSFETs are connected together. You forgot about "Intrinsic Body Diode" aka Reverse Current Path of MOSFET. The Cathod of two body diode of MOSFET pair are connected together. During OC protection, the MOSFET(OC pin of DW01A connected with the Gate of this one) is turned off so the charging stops immediately and the vice versa for OD protection. The same thing you can turn for positive line with a pair of P-Channel Enhancement Type MOSFET. By the way, thanks for the great effort.

[@RogerTannous]

That's true, when one MOSFET is on, current passes through it via the anti-parallel diode of the other MOSFET. The explanation in the video is clearly wrong, because same-type MOSFETs cannot let current pass Source-to-Source when their Drains are connected!

how to increase current output? it's posible for change of the mosfet for increase current output? maybe use AO3400 or 70N03. help me please for my question 🙏🙏

[@nataf10]

Hi, Did you find an answer to your question? I'm trying to use this module with my 3.6v screwdriver, but right with I turn it on the current protection start and cut the output voltage because of the rush current at the beginning when the motor strat spinning. Is there any solution for this case?

[@profx2020]

Great to see a review of J5019 and its lack of undervolt/discharge protection (lack of DW01) and if there is alternative board with tp4056, adjustable boost to 6v to 12v+ like j5019 but with dw01 prior to booster for discharge protection.

[@ahmedlotfy8972]

You saved me alot of time, Thank you.

[@riyadabdulhafeed2899]

Great effort,full explanation

[@DownhillAllTheWay]

I have to replace a battery, which contains a little board with two chips on it. One is the DW01A, which brought me here, which was good because I couldn't find a datasheet for it. The other chip is the SM8205, and I can't find any information on that either. I can find suppliers and even pictures of the chip - but no datasheet. I don't suppose you have any info on that one? It has 8 legs, but legs 6 & 7 are bridged with solder. This was a very informative video, by the way - but unfortunately, it doesn't cover the chips on my battery. Maybe my 8205 does the same job as your 4056 - or maybe not. Incidentally, there are two straps from my battery to a little circuit board containing these chips, then there are three wires from the board to the minicomputer board that it powers - red, black, white. I don't know if the white one is for charge monitoring, or for temperature.

[@mjhaynavarro]

thats great explanation. thanks for this.. may i just ask what is the B+ and B- voltage when battery is not connected?

[@KunalKumar-hb8zy]

Well explained 👍🏼 thanks for the informative video. I think the (-) of battery should be connected to 1,8 pin of FS8205A chip instead of pin 2,3..and actually the load should be connected to pin 2,3 ... that would allow it to be isolated from either part(charging or, discharging) of the circuit... Currently both charging and discharging path is common so when it disconnects it because of OD(over discharge) it also disconnects the charging path.. same while disconnecting because of OC(over charge/current) it disconnects the load also... Please correct me if my understanding is wrong.

[@chonkaaa7473]

I think I agree but pin 6 of the protection circuit needs to be connected to ground, which it wouldn't be if the overdischarge circuit protection turns on as it would disconnect the path from 1,8 to 6. Also, connecting the B- to 1,8 and OUT- to 2,3 would disconnect the load from the charging port either of the MOSFETs closed, probably not intended.

[@moushi5019]

The maximum current of TP4056 is 1A, which is too slow. I need 3A to fast charge the 18650 battery pack, so I modified the circuit and saw on the Internet that using three 4056s in parallel or using P-channel MOS are not good methods. Is there an optimal solution? I used a 0.22 ohm 5-watt cement resistor across the 5V positive power supply and the positive electrode of the battery. The battery started charging at 3.3V, with an initial current of 3.2A. When it was charged to 4.18V, there was still 1.5A. At 4.25V, the DW01 protection action was locked. The current is zero, and the discharge current is 3.1A. It automatically cuts off in 10 seconds. I don’t use protection and directly supplies 15A battery. Very easy to use

Hi, if you want to make a setup with more batteries doesn't need the first chip (next to the usb) isnt't it? It can be one for all or/and a microcontroller

[@sanjaybatra6593]

Awesome Video. One of best video to understand datasheet and deep learning. I have four questions. 1. Is there more advance chip available as compared to TL4056 ? Is TL5100 is better ? 2. During charging of battery , we can connect load ? 3. I want to use TL4056 for charging 18650 battery and simultaneously use it for AVR microcontroller, which work on 5V. please suggest , it can be used this way ? 4. which DC to DC buck converter is suitable for 18650 LI-ion Battery? Input : ( 3V to 4.2V) and Output 5V/2A current .

[@vstop2176]

Why its give 0.4 to 0.8 voltage at output terminals. Somthing goes wrong but I am not able to find please help me

[@WattHour]

it must be dead if the input has voltage.

[@demef758]

8:35 In THEORY, you can connect the input to 8.0V, but if you do, the 4056 charger chip will dissipate a peak of about 5 watts with a 1A charging current, causing the chip to throttle back charging current. Most people will just use 5V, not 8V, which causes the 4056 to dissipate 2 watts for a while. Many users complain about the heat the tiny board produces, and this is why. If heat bothers you, reduce the charging current.

[@alaksandrshpak5500]

how can I increase 2.5V over-discharge to 3.4V? with save the 4.2V over-charge limit

[@WattHour]

you can't. it is set by the chip.

[@hoff_6112]

Great vid!👍 Would it be possible to increase the overdischarge voltage by increasing R5? 2.4v is way to low for my project😖

[@hoff_6112]

I added 400ohms resistance between ground and the chip side of R5 and it raises the overdischarge voltage to 3v!😍

[@Vinod-xw2bx]

I also have same 😊 question I need cuttoff at 3.2V any solution please

[@hoff_6112]

@@Vinod-xw2bx hi mate, if you connect 300ohms of resistance between ground and the DW01 chip side of R5 you'll get a discharge cut off of 3.2V or close to👍 the only problem is I think it also raises the voltage that it cuts back in from 2.9 to 3.7V🤔

[@Gengh13]

Another problem with the idea presented in the comments is that you also increase the overvoltage protection essentially disabling it.

[@tamasjuhasz2983]

Hi! I have one such module. The blue (standby) LED does not light up when charging is complete. The red LED, on the other hand, is constantly lit. On the other hand, it charges the battery because I measure 4.2V on it. What can cause this? Thanks for your response!

[@ashuntu2010]

I think the red LED keeps on even when the battery is fully charged is because you have connected load to the board. If the load is connected to the board, the board will always keep red LED on unless you remove the input supply to the board. But I think when the battery is fully charge the current to the battery will stop which the TP4056 will keep flowing current through it to power the load but not the battery.

[@WattHour]

do a "google" or "bing" search.

[@jjustinengineer]

At 10:43, you indicate that both the OC and OD are not connected in the schematic. But they are connected in the schematic - check it. It made me believe that there are some versions of the module that don't have both connected - which isn't true - and would be ridiculous. If the DW01 is present, then both overcharge and over discharge protection is there. It wouldn't make any sense otherwise.

No protection for reverse nor for 12V. It will die.

[@jasondoyle1037]

I can confirm applying 12v in will blow the tp4056 apart. I did it myself by accident!

[@generalawareness101]

TP4056 when does charging come on? At what voltage? We don't want, nor need, it to "top it off". What I am getting at is that below a certain voltage then kick in the charging but not before. You only get so many charging cycles, With solar powered equipment it will charge each day unless a circuit prevents that until a minimum voltage is hit.

[@WattHour]

both has been explained. start of charge and stop. I have shown data sheet and spoken about it I remember. you may have skipped the video.

[@nostalgicmusicbox]

Hello, great video. I don't know if you'll be able to answer this since it's a 3-year-old video by the time I put Make this comment. But I don't know if I'm doing something wrong or if my entire batch of 20pcs of ts4056 are bad. USBC version. It has the extra protection. But when I plug it in. No lights turn on. Doesn't seem to charge. I've plugged just the USBC in, I know that the plug is good and the power supply is good. But it doesn't seem to have any voltage going through the terminals connecting the USBC to the board, or from the battery output and input. Or to the component. But I have wired it up so that my battery will go to my lights. And that works fine. But it doesn't seem to charge. The lights don't turn on if I plug it into a power source via USB or to the batteries. Or from the batteries to the component. I've tested five out of the 20 that I bought. But I at least know that my battery will power the component I'm plugged into. On that note, since I can't send them back. Is it still a good idea to be using this as circuitboard that can protect my lights from the batteries messing up or anything? Or should I just unplug it and buy new ones? Which I do have new ones on the way but I now have possibly 20 of these completely useless boards.

[@TroyeWelch]

It’s probably your power supply. Some of the (PD?) supplies use the data pins to negotiate a voltage since some devices like laptops can take higher voltages (20 volts?) to get more power out of the usb-c connector. These charging boards are dumb and don’t do any handshaking. Try a basic 5 volt supply and/or bypass the usb-c jack. I read somewhere that shorting the data pins might signal the power supply to generate some output, but do your research!

[@nostalgicmusicbox]

@TroyeWelch I actually just figured it out the other day. It was the cord. Some courts just don't work with this chip. I have two different manufacturers and they both have the same issue. But my 90 watt cord willpower my soldering iron but not the TP chips. As soon as I plugged in the correct USBC cords. The lights came on. I was just so used to using the cord that came with my soldering iron, I figured it would be fine.

You can add a 330ohm resistor between ground and the chip side of R5 to increase it to around 3.1v. Lower the resistor to increase the overdischarge voltage 👍

Over discharge protection is basically a lie then? If you discharge down to 2.5v for any significant period of time the battery is effectively destroyed. To which I suspect you will say its to deal with voltage sag... This just means its going to ocilate and still likely kill the battery.

I am not impressed with the TP4056 module. It takes a long time for unit to charge one battery and even longer to charge two batteries in parallel. I can honestly say this is a mediocre, NOT VERY GOOD, charging board and no one reviewing it or testing have the expertise or guts to say it. Except for one, this engineer warns people not to use it as well as other charge modules. I agree with his conclusion. It is better to just use a real charger like XTAR. I am glad I found at least one honest person that says it like it is.
