Hi, guys! Long time, no see :)
I had some personal stuff to do lately, but I will start making videos more often now.
In this episode I will try to modify a TP4056 module and charge lithium cells with more than 1A.

To enhance the module, I located an old PCB saved from a small radio. For volume, it contains a 10K volume potentiometer in series with a 1K resistor. I cut out that section of the PCB and double-sided foam adhered it to the back of the TP4056 module, with two wires directly to the R3 connections replacing the SMT resistor. This gives me a range of 110-1200 mA charging current options without changing resistors, these values I marked on the thumb wheel with a laminated label. Thanks for the entertainment, information, and cuteness! It was inspirational at the least :)

Interesting experiment, however it just demonstrates the internal overheat protection in the chip. Note that most of the TP4056 chips are fake clones so other ones may not work as well as shown here. If you want a simple module that is rated 2A, then use the TP5100 instead of the TP4056. It's more efficient, since it's a Switching rather than Linear controller, and you can program it to charge 1S or 2S (8.4V cutoff).

There were no explosions and just a lover charging current because the chip has an internal temperature sensor reducing the duty cycle. In the complete datasheet, you can see it have an internal comparator set to 145°C vs DIE temp. But from graphs, you can see it kick in around 110°C on the package. So more cooling = even more current. 😉

@johncoops6897 2 жыл бұрын

Yep. Since it's a Linear Regulator the more wattage (Volts AND Amps) being dissipated the more heat is internally generated. However the IC package is not designed to dissipate high currents, so they rate it for 1A bare (no heatsink and fan). If you want more current there are absolutely tons of cheap and better ways than a TP4056.

Is that 18650 or different, because I also studied we need to charge a lithium battery with its 37% of capacity current rate and exceeding that percentage can damage the cell.

@Sorin_DIY 8 ай бұрын

It depends on the type of Li-Ion cell. if you use old, untested or cheap cells you should start the charging process at a 0.2C rate and check if the cell gets hot. good quality cells can be charged at a 0.6C or even 1C rate

I found that the TP4056 chip is soldered down to the board under the body of the chip as a heat sink. If you take a look at the back side of the module, there is a group of vias directly under the chip leading to a plane of copper on the bottom side of the board. I found the best place to put a heat sink is actually under the board, not on top of the chip. I did this and it was surprising that you can keep your finger on the top of the chip even though charging at 1A and beyond. I also suppose that keeping the input voltage closer to the battery voltage might reduce the amount of work the TP4056 has to do, I ran it around 4.4V instead of 5.0V and that worked well too.

Salut. pentru 1A rezistenta programabila trebuie sa fie de 1200ohm, iar pentru 2A rezistenta trebuie sa fie de 600ohm. nu exista un potentiometru care sa varieze intre aceste valori. poti sa folosesti un potentiometru dublu de 1Kohm, sa lipesti in paralel pinii potentiometrului si astfel dintr-un potentiometru dublu de 1K sa faci un potentiometru simplu de 500ohm. si acest potentiometru sa il legi in serie cu o rezistenta de 680ohm. deci in final o sa varieze intre 680ohm (1.76A) si 1.18Kohm (1.01A). varianta asta cred ca se incadreaza cel mai bine intre ce valori vrei.
