4:44 the values of r1 and r2 depend on the value of thermistor that you use, and what temperature range you would like to achieve with it. So it is up to you to decide. I have used ChatGPT to calculate the appropriate values for my thermistor and desired temperatures.
@@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 :-)
Nice Dario! Looking forward to when your lab has been cooled down a bit😊 I live in the middle of Sweden, 400km north of Stockholm, so almost never get that problem here. // Roger
I will make more videos about tp4056 soon. Unfortunately at the moment it is 36° in my lab and it is very difficult to work! As soon as the temperatures drop, more interesting content will be coming! See you soon buddy!
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)
Is it’s possible to modify 4056ic for minimum 3v input? I want to drive 3v 5 watt led with 18650 Battery, i already using 5v charger and tp4056 with adjustable regulator for driving table lamp, it’s work great, now i want a 18650 Battery compatible rechargeable version of it
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!
Hi, do you think the smaller one with no protections + a BMS will work? I need a BMS because my load will be about 10A, which neither of these can handle
@@dariocose thanks a lot, yeah I'm making an LED driver, and the strip might draw something around 7A max, so I will buy 10A bms and 18650, because they are capable of even 20A or so.
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.

Thank you very much for the tip!
I will try it soon!
I would love to see a video on how to connect a NTC thermistor to the TP4056 and finally get to know how to set the right values of those resistors.
❤
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!

34° today... 🥵
There should be an onboard potentiometer to adjust the charging current..
Useful video. Would help to have a video from you on adding reverse batt protection and how to use the TP4056 module in load sharing mode. Thanks.
I will make more videos about tp4056 soon.

The charge current monitoring is also why you should not connect more than 1 cell. As the current will be higher than the cutoff threshold
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.

can easily connect more cells in parallel. The TP4056 just delivers current and has no idea whether that is to 1, 2, 3 or 50 batteries.
Thank you for sharing your knowledge, and greetings from Germany!
I'm glad you liked the video.

In brief: No, not possible, but what you can do is put a booster in front of it. Ofcourse it all doesnt add to the efficiency of the power use

Hi.
A tp4056 without protection will definitely work better with a good bms.
10A is really a lot. Look for a bms and batteries suitable for this load!
@@dariocose thanks a lot, yeah I'm making an LED driver, and the strip might draw something around 7A max, so I will buy 10A bms and 18650, because they are capable of even 20A or so.
Thanks for sharing 👍🏼
Can i use this module to charge my 10000mah battery?

@@azharmukhi5894 thanks for the tip
Thank you
Nice tips
The Ai voice is fucking me up. I rather take broken engrish than ai; otherwise thumbs up
My friend, I am Italian and I have a terrible accent. Believe me, the robot voice is a better option!
Please don't use such annoying music 😡
thank you
