My DIY 18650 Battery Charger

I admire your hard work, your patience, intelligence, and your dedication in sharing your skills. I am a lazy dog that does not have the patience and time and would rather buy a finished product. cheers and more power Master Sorin!!

When you consider the range of tools used here, the result is pretty good. Nice with a DIY video without the use of CNC, 3D printers and other expensive machines. Good job, and good explanation.

[@jagardina]

Very cool project. I probably would have tried to make it possible to take it apart and change stuff, all the glue is somewhat permanent. But when I first saw it I did not think it was wood.

[@frankenjid5156]

I accidentally bumped into this video and had to watch the entire thing. You have seriously impressive skills, nice work and nice video. Thanks!

[@jamest.5001]

When I first saw it . I thought it was 3d print! Nice job. Mine takes up about 1 sq meter! And only charges 12 cells ! And discharges 3 cells. Nice! Have you thought about using some thermal sensors in a silicone gel or something to get the charger/dischager to shut off if the cells get hot? I was getting up mid night for batt change. And put a cell in back ward twice. I started using more light when changing cells. Trying to charge and test 100's & 100's of fast as I can takes a long time. So I got up mid night for cell change for two months plus. I have 98 to go. Then time to get more! I only need about 10,000 cells with 2.5-3.0 ah each. (2600-3000 mah each.) In a 29.4v 7s bank. It's gonna take time!!!! I'm only like 1/100th through that at best. I guess about 5k cells would work. But what's wrong with excess!!! Nice video!!

[@SharvilSawargaonkar]

modules that have over discharge protection (dw01) ic has reverse polarity protection so connecting the battery in reverse wont damage the module

[@jamesrodemeyer7544]

You have a great project, but I thought of a addition, how about a voltage and tempreature connections to a Nano then to the computer so you can monitor and record these parameters. I connect 4 leads to the positive poles of the battery and 4 thermisters to the battery holders mounted in such a way as the press against the batteries. I am writing a sketch to monitor these valuse and send them to a computer useing putty. If you want more info let me know.

[@daijoubu4529]

You can replace the SOT23 protection IC with a FS312F with a 2.9V cutoff instead of your typical DW01A

wow awesome. Could you make one that lets you set the voltage to charge to or discharge to? I know lots of people that would love this and if you put a kit together I'm sure you would get some community support :)

[@rosekreuze]

i just hook up everything directly for the meantime: the battery to a usb voltmeter in between, and the resistor. it doesnt have a cut-off so im closely monitoring. i just want to discharge it, also at 3.59v while under load using 10w10ohm i am only drawing 0.29 amps. would you recommend a higher resistor value to speed up the process? its already running 3 hrs 39 mins and so far the total mah drawn were only 1071 mah

[@Sorin_DIY]

for a higher current you need a lower value resistor I=U/R. if you want a higher current, you can use a 10W 6.8ohm resistor, but it will get very hot.

[@rosekreuze]

thanks alot! that will do and with proper heat dissipation i suppose?

hi. it is a bit expensive, because it has a lot of components. but I like these tp4056 charging modules, they are very useful in a lot of DIY projects. you can make a cheaper charger with these charging modules, without all the other components, I have a separate video for that.

Did you put a pull down resistor on your sensor wires so your voltage reading doesn't have a seizure when you remove the battery? Even a 10M pulldown will be fine, which would drain nearly nothing.

Chiar foarte misto ideea, nu m-am gandit pana acuma ca pot sa-mi construiesc un incarcator de baterii in loc sa cumpar unul. Nu era o idee mai buna sa iei un controller de incarcat LiPO mai bun, ca sa ai doar 1 pentru toate 4 bateriile ca sa poata sa fie incarcate toate la acelasi nivel?

[@Sorin_DIY]

salut. se poate si asa. insa daca probezi baterii diferite, cu capacitati diferite, unele pot fi chiar defecte, nu poti sa iti dai seama cat de repede se incarca sau descarca fiecare. daca o baterie se incarca si se descarca foarte repede, nu se mai poate folosi impreuna cu celalalte.

[@axoselectronicalikee3230]

hola excelente vídeo , hay alguna forma de saber la capacidad descargada en amp, total de cada celda? mencionas que la descarga con esa resistencia va desde los 450mha pero baja con relacion al voltaje de la calda , es ovio pero daría un estimativo con relación tiempo , de la capacidad total hay algo mas exacto de forma casera que no sea arduino ? agregándole transistor q haga variar la resistencia así a medida que baja el voltaje .mantenga los amp de descarga , gracias y perdon no hablo en ingles saludos

[@Sorin_DIY]

Hola. para un cargador de celda DIY 18650 es difícil medir la capacidad exacta. Puede agregar un módulo de prueba de capacidad barato de China. Otro método impreciso es agregar un convertidor reductor, bajar el voltaje de la celda (de 4.2 ... 2.5V) a 2.5V estable. luego conecte una carga de 10 ohmios. consumirá 250 mA hasta que la celda se descargue. digamos 6h. multiplica 2.5V * 0.25A * 6h = 3.75Wh. divide 3.75Wh al voltaje nominal de la celda, que es 3.6 o 3.7V; 3.75Wh / 3.6V = 1.04Ah. pero esto es impreciso, porque la eficiencia del convertidor reductor varía según el voltaje de la celda. cuando el voltaje de la celda se está reduciendo, el convertidor extraerá más corriente de la celda para mantener una salida estable. entonces su eficiencia fluctuará probablemente entre 95-85%. así que en realidad la célula tendrá 1.1Ah o 1.2Ah ...

[@sorinmariusbuturugaru1085]

whats your opinion on using 1 module for charging two similar -brand new batteries ? thanks

[@Sorin_DIY]

hi. yes, you can connect 2 cells in parallel to one charging module. if the li-ion cells are new, it's better. you can also do this with old cells, but they need to be the same type, have the same capacity, same life-span, same charging cycles and use them in the same parallel configuration.

[@Chris0612]

Thanks for this great Video, i will build this thing for sure. If i want the charge feature only, how do i have to connect the displays?

[@Chris0612]

I don´t understand the schematics with the wirering of the switch also :(

[@Sorin_DIY]

hi. if you want only to charge the cells, you need simple switches with 1 pole and 2 positions. the negative wire from the 5V charger is common. is connected to all TP4056 modules and all the voltmeters. the positive 5V wire from the charger is connected to all the voltmeters and to the switches. each switch will deliver the positive supply wire to 1 TP4056, so you can turn them on individually. the voltmeters sensor wires are connected to each li-ion cell positive terminal.

hi. with 4 charging modules you can charge 4 cells individually. the cells can have different capacity, they can be discharged to different levels. you can put each cell in the charger at different times. all the cells will be charged much faster, with max 1A. not 1A divided to all 4 cells. if you want to charge multiple cells with only one charging module, the cells must always be connected in parallel (when you charge them and when you use them). the cells need to be the same type, same capacity, same lifespan, same charging-discharging cycles and they will be charged 4 times slower -> 1A/4=250mA each cell.

hi. it's normal for the TP4056 IC to get hot, while charging with 1A, but not enough to melt the hot glue. hot glue fixes the circuit board to the panel, the circuit board should not get that hot. you can use a small self adhesive heat sink on the IC.
