Thanks Sorin, I haven't solved the shorting on inputs of TP4056 until I saw this video. I constructed my own powerbank and UPS for my laptop...thanks a lot for your diagram and test done on your video. I had learn a lot from it. Keep it up!

[@diyexplorer8728]

Nice project and your cat too.

[@davestech6357]

I've seen people do this before. What they always miss is a diode across each charger output to avoid negative voltage going into the charger when one battery drops out under load.

[@mwint1982]

Diode across the battery output B+/- or the OUT pins?

[@rhiantaylor3446]

I was thinking of building something like this using hand-wound secondaries on a toroidal transformer. Benefit is that each "cell" is isolated from others so the outputs can be connected in a series string as in a Ebike battery. Also allows the voltage into each TP4056 to be kept to the minimum to achieve a full charge, to reduce dissipation.

[@coolgamer1989]

i did same thing using different 5v power supply from usb chargers up to 2A each, and used 2 TP4056 for each charger to balance batteries up to 2A, i use this to balance Ebike and electric bikes batteries, and really worked great for about a year, did one to balance up to 20s battery packs :)

[@keithking1985]

wow Sorin your channel has grown since i 1st subscribed!! May it keep growing... class video!! just one thing the 2nd connection diagram you showed the TP4056 module's didn't have discharge protection just over voltage protection. there two types!! the better one has more chips(3 chips) on the board. for those of you new two this module & are looking them up/buying online, get the one with 3 chips on the board because it has the over & under charge protection. hope this helps!!!!

[@temelius86]

Yes, there're two type of this modules. The modules in the first diagram have also discharge protection and in the second diagram have not, because there are no output pins on them. They are only for charging process. The first module that never works again after short circuit can be broken, because the other three modules are still working. I wonder where is the output voltage of this module supply from. Is it show 5v when power in and the battery connected and 4,2-3,7v when only the battery connected, not the power in?

[@valentinpopov1114]

I think the idea is great and helpful. I planed to build this for a while... I am using imax b3 that work probably exactly the same way, but i dont think I can hook them up in series. This thing wouldn't be a problem if you have 5 4s chargers... Just to connect them in series to get a 20s for a fast ebike for example. The con is... Power consumption for thee transfermer... I was liking forward to see you measuring consumption. Before the transformer and after it and... And after the full bridge rectifier...

[@ronaksoni2729]

[@station240]

Get yourself some Polyester Tape to use instead of the masking tape. It's the yellow tape used in switch mode power supplies, comes in different widths, and is cheap. Using masking tape is just a bad idea, it comes loose after a while as the glue gives up.

[@rpbajb]

Agreed, masking tape is a poor choice, transformers can get quite warm. Kapton tape would be best, but it is more expensive, of course.

[@joakoc.6235]

I did that same circuit that you did, but with independent 5v switching power supplies, the problem is that when one battery cell goes below 2.5v with a discharging current over 1 amp, the TP4056 blows up, it will overheat and burn out, the charging light stays on and the 5v input now outputs the voltage of the battery, like what happens when you do the short circuit.

[@sadsaeqwqwrwqrqwr2639]

Bu modülleri seri bağlayarak kullandığınızda, pillerden biri bittiğinde modül içerisindeki elemanlardan biri çok ısınarak yanıyor. tahmini açıklamam ise çıkışı kontrol eden mosfet sürekli kapanıp açıldığı için üzerinden geçen akım ile mosfet'in direnci arttığı için ısınıp yanması.

Hey there, nice video, but i would change the tp4056 modules with some tp5100. Theese use step-down to regulate the charging current, so you can feed them with up to 18v, are also programmable, and won't heat up nearly as much as the tp4056. They don't have a USB port, but you're not using them here so...

those will work too. but I wanted to test TP4056 modules, because they are more popular.

[@nicksimpson5256]

Great video, great job! You have a fantastic channel! I have a question for builds like this, with 18650 cells. Most charging chip-sets (tp4056, dw01 etc) will charge the cell at 4.2V (which is the top limit according to the cell's specs) and some even more (4.25 or even 4.30) putting a very high strain on the cell.. since the charging chip's parameters cannot be changed, if i wanted to finish the charge cycle at 4.15V just to feel safer, if i put a resistor between one side of the cell and the charging board, would that make it stop the charging at lower voltages than 4.2V..? And the same for discharge.. is there a way to increase the lower cut off voltage to 2.7 or even higher so that the cells don't get so stressed? I don't care if I loose some of their capacity.. just want to feel a bit safer for their parameters...

[@Sorin_DIY]

hi. I don't think it will work with resistors. resistors will decrease the current. if you connect a resistor in series with the cell and charge it, the charging current will be lower. and near the end of the charging cycle, the charging current will be very low, so the difference of voltage before and after the resistor will be very small. it will charge the cell with a lower current longer time, until the cell voltage is 4.2V. and for the discharge cycle I don't think the protection IC will read correctly the voltage and current, so it may not work correctly. if you want to power you project with 1 cell, there must be other solutions. for example you can use this module for over-discharge protection: www.aliexpress.com/item/32788948905.html?spm=a2g0o.productlist.0.0.266c7eee3jze8x&algo_pvid=acf82334-569f-4c28-b4ae-57b0187fa6dd&algo_expid=acf82334-569f-4c28-b4ae-57b0187fa6dd-36&btsid=0ab6f81615901736350356638e1753&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_ Over discharge voltage:2.54±0.1V it's not a big difference, but it is a little better than TP4056. or if you need 5V for your project I recommend this module: www.aliexpress.com/item/32885492747.html?spm=a2g0s.9042311.0.0.27424c4dr4JFVo it charges the cell to exactly 4.2V and it has over-discharge protection at 2.9 - 3.0V.

Great job Sorin, have you had a chance to check out my video doing the active balancer using tp4056? I made a 10s charger. So far it’s working pretty well and charges each cell using 1 amp per. It was a fun build that’s for sure!!!

@@Sorin_DIY That is pretty cool!!! Mine has transformers....LOL, just a whole bunch of mini 5V ones...LOL. I wasn't looking for a BMS like your build. Just a way to charge some of the 10S battery packs I'll be building. I looked everywhere for a cheap alternative and couldn't find one, so I decided I might as well build one myself. With this one, the best way to use it is to charge the pack to around 75-80% full and then plug into the active ballancer I made. It can charge the pack from 0 to full, I just found it faster to do it the other way. Love your video and your work!!

That was fun tp4056 in series :-) Is there a way to do the isolation without a transformer? For use in a solar setup? Since that is all DC we would have to make AC and than go back to dc.

[@Sorin_DIY]

hi. another option is to use DC-DC isolated converters, but they have a low efficiency so it's not recommended. you can use a solar panel and a CN3791 solar charger and a 6V/9V/12V solar panel for each lithium cell. this method will have a better efficiency, but will cost a lot. the most efficient way is to use a solar charge controller. and the cheapest way is to use a buck/boost converter and a BMS board.

[@hansdegroot652]

I have 2 42 volts and 2 +- 35 volts panels. The are just stupid voltages giving me headaches. My e-mopet has a 48 volt battery (which means it is 54 volts) and the charger can peak to 60 volts. Most you tube examples go to 30/35 volta examples max andso far I am to big a electronics noob try to change the exmaples into something that works for me. Lots of magic smoke.

I used the TP4056 modules in my DIY flashlights for charging the 18650. I found that the module keeps discharging the cell even when not in use. The cells always went to 0% within 3 or 4 weeks. It is not regarding one or 2 particular modules. I tested many, and they all do the same. Then I had an idea. I added a switch that disconnects the TP4056 from the battery. And another hidden switch which is only used for turning off the LED while charging. Now the battery holds the charge for more than 6 months. This is the best idea so far. But then so, I want to ask you, do you know any onboard/offboard modification for the TP4056 so that it wont drain the cells constantly? Thank you.

[@Sorin_DIY]

hi. I never had this problem with TP4056 modules so far. it shouldn't discharge the battery in a few weeks. are you sure you've done the wiring correctly? I built a lot of powerbanks, portable speakers and other devices with TP4056 and they don't have this problem. what other components did you use in your project?

[@KetansaCreatesArt]

@@Sorin_DIY Hello, I used XML L2 LED, the 5 mode driver, TP4056. I was using a switch just before the L2 driver, like it should be. It drained the battery. Then I decided to totally cut off the TP4056 with switch, as a main switch. Now its perfect. Then I also did the same changes in older projects and the batteries stopped draining.

[@FixDaily]

that's because your Bluetooth speaker is not taking too much power out of the powerbank and your powerbank thinks there is no load attached. They way to solve this is to connect a parallel resistor (to the powerbank ) to draw some current and makes it active all the time. Try to draw 100mA and see how it behaves, if you can decrease the "standby current", better it will be :)

[@creativeabhishek5842]

Can i connect 1k 5 resistor in parallel

[@FixDaily]

@@creativeabhishek5842 1K would draw 5mA, i'm not quite sure if this would be suitable to trick the powerbank, but start from there and lower the resistor value if it still doesn't work This post suggests 22ohms, which will draw 227.27mA (but probably this is too much power consumption) hackaday.com/2013/11/08/tricking-a-usb-power-supply/ Try it out, lower the resistance value until your powerbank remains on.

1k x 5 in parallel would be 200r So a total of 25mA. Not quite sure if it is enough but as i said, you have to try it out.
