I wanted to build an 18650 multi-cell charger to help me get through the many cells that I have to test so I decided to do that with the TP4056 18650 charging module.
I did something like this with a 12 volt server power supply and ran it through a 5v 30amp buck converter. I didn't finish it, only prototype a 4 cell section. I have a 600 cell shipment coming in so I may start up again tmrw. Thank you for the idea for wiring from a main line with the little cut out.
Wish I had seen this sooner I am doing a 40 cell charging board with the TP4056 muduals was not sure I could wire the power that way so mine is kinda a mess of wires it works fine need two more to finish then I bought 40 capacity mudules so I can process my 2200 18650 I am repurposing for 4 -24 volt 120 ah battery packs . I am putting 10 renogy 300 watt panels on roof of my coach bus onversion with a Victron 150/100 MPPT solar charger,two Victron Multiplus 3000 watt inverter chargers. This battery building is taking up some time looking for faster ways to tst them all.
Very nice video! but I have a question, maybe someone has experienced the same. in my experience different tp4056 charge at different cutoff voltage. The ones I received vary from 4.10 to 4.15. Some module will charge up to only 4.10 some to 4.12, 4.13, 4.14 and 4.15. It is like that always? I even tried using different power supplies and still same result. Thanks a lot.
At what voltage and current input does that whole wall charger running at? I want to make something like this before i saw this vid and im still not sure what input current should i need to use. I have in mind the 100 cell 18650 charging that is just like these setup
I'm running a 5v 100amp power supply, the tp4056 modules will only work with 5v. Potentially you would need all 100amps if all 100 cells are below 4v due to the constant current of 1amp up to 4v and then the current tapers off... But so far I haven't had any problems everything is working its actually overkill because I can't capacity check cells faster than this charges... But it is good to charge, let them sit for a while then check... But getting way ahead on charging.
Ran pretty good long term, cycled 7 or 8 thousand cells. I never had a problem. But I also never had 96 fully depleted cells on the board at a time, since I would charge 96 cells of various soc and as they were fully charged I would pull them and put them on the opus chargers for discharge capacity testing, then once I got the capacity I would throw them back on the board to charge them back up... I could only discharge 28 cells at a time so really I was swapping all the time. So probably never really experienced a peak current draw. Now it just collects dust on my wall as a reminder of the pain and suffering I endured making 2 - 10kwh packs... Tens of thousands of spot welds lol.
Lol right!? I actually just finished building a 1680 cell pack 7s240p 10.6 kwh... It took so long and a lot of spot welds I cringe at the sight of rest of the batteries... Still testing many many batteries...
how much voltage drop do you realy have at the end charger kabels . i think there would not be 5 volt anymore cause if you charging witch 1 amp your using 96 amp . or are u charging with 500 ma
Is it safe to use with cells of unknown historic ? I need to repurpose thousands of powertool 18650 cells, how can i determine safely the capacity of everycell ?
hello yes it is not easy to solder on the screen it looks big but in reality it is very small to do and it is better to be good with your fingers some videos in general from asia do this quite easily i wonder how they do it and with very low quality material... i already tried with pcb boards seen on youtube but it's too hard to connect.. .
Question: what gauge wiring did you use on the tp4056, From the solar cables you used from the main power and from the 18650 battery terminals to the tp4056. Also since your draw is near 100 amps with all 96 cells charging at once. You mentioned you needed to upgrade your power supply to be able to provide the proper amount of current. Wouldn’t you need to upgrade that XT-60 connection as well, to at the very least a XT-90?
XT-60's can handle up to about 130a before actual damage occurs, however, it is going to be less efficient because some energy is going to go into heat. The XT-60 is going to act like a bottleneck, but it wouldn't be too much of a loss, simply because of the actual current limit of the connector. Despite the 100a number, it's only at 5v, so there isn't as much wattage going through as you might think. This setup would probably benefit from an XT-90 when it's at full load, which I doubt is very often.
You need a charger capable of producing the correct voltage. I use an icharger x8 for my 7s banks, it's best that any charger you get be capable of setting the final voltage, for example 4.1v/cell (28.7v) instead of 4.2 (29.4). I also charge using a solar charger controller when not home, once again capable of adjusting final voltage...
I unfortunately bought 200 units of scraped laptops batteries, in the process of extracting, all the cells in about 150 unit's are not just dead but rusty. About 100 cells in the salvaged 50 units deliberately refused to charge and the remaining units that managed to charged were all very very hot. It seems the batteries has been kept for 10 years, I ended up throwing away 209 units of laptop batteries. Make sure to double check before you buy.
Good idea... If I end up reworking it I might do something like that. But for now I just say "positive to the top" over and over and hope my hands follow my instructions 😂
@@wmonte75 not these ones lol 😂... I did one backwards, both red and blue LEDs came on, but after you remove the cell, that board doesn't work anymore...
Well my first laptop batteries were from ebay, unfortunately being from Canada there are very few sources of cells available.. Used cells that is. But earlier this year I scored a large lot of batteries locally..
@@dylanc9275 I hear you.. It sure is funny, once you start collecting these cells... You always want more lol. I picked up 4k cells for $600 bucks.... That was just luck.
@@dylanc9275 from a company that was closing shop in bc and moving back east and the customer build battery thing never went anywhere for them so score for me. 27 boxes of 168 cells... It was a good day 👍
That's what I felt like building.... Worked out that it would take 25 days 24hours a day to charge most of the cells. I ended up making a 8/16 cell charger. Small and portable! But... Down side is that the tester is only 4 cells. I could have got more of the testers, but the pack build is 'for fun'. I'm 3 weeks in and wish it was new cells. Then it's only charging that's needed.. Mine will be a run away, don't do it video coming up.... Good ideal, but you don't need the monitors as you can manually do it... I'd have some volt meters on there so you can see what's going on.
Correct. This video was not to test but to charge all of the batteries that I have, let them sit for a few weeks, then run them through charge discharge cycles on the opus chargers that I have...
This looks awesome you did a great job
Very useful video for li-ion cell charging in bulk quantity 👍
amazing project..,

Very practical easy to check and maintain
The most important thing you can easily replace the faulty cell
Wonderful !

Where did u get the Power Supply?
How much did the whole rig cost?
links to tp4056 you bought?
how can i get series output .. when charging?🙄🙄
@Having'Fun where did you buy the pink and blue containers @13:46 ?
was wondering the same.... i at least need to know how it,s called,
Curious how this went long term? From what I have researched the XT connectors are rated at max amps and they should run at 50% constant load.
Ran pretty good long term, cycled 7 or 8 thousand cells. I never had a problem. But I also never had 96 fully depleted cells on the board at a time, since I would charge 96 cells of various soc and as they were fully charged I would pull them and put them on the opus chargers for discharge capacity testing, then once I got the capacity I would throw them back on the board to charge them back up...

I'm more impressed about what you're doing with all those batteries than the charger. How many flashlights do you have really ? : )

@@havinfun4014 so worth the labor though, I know for cell prices lithium isn't that expensive in relative terms but they're still expensive
@@skm9420 yes, totally worth it! Have it at my rec property, works really good, will bring it back before winter and give it a checkup.
whats psu you use for charger..??
how much voltage drop do you realy have at the end charger kabels . i think there would not be 5 volt anymore cause if you charging witch 1 amp your using 96 amp .
or are u charging with 500 ma
nice video
Hi, what's your wire size? is it 10AWG? can they do 96A?
How to balance?
Is it safe to use with cells of unknown historic ? I need to repurpose thousands of powertool 18650 cells, how can i determine safely the capacity of everycell ?
5v 100amp SMPS charger is ok to charge these cells
Disculpa a qué cargador o adaptador conectas los cables principales
Input voltes ampr.......?
Bro 96 bms and around 15A of parallel charger to maintain the batteries wont heatups
hello yes it is not easy to solder
on the screen it looks big but in reality it is very small to do and it is better to be good with your fingers

Paralel tp4056 w/ balancer just make you big problem, input negatif is not individual, its linked...

@@havinfun4014 thank you for explaining but how can I get the i charger?
how mny hour you charge the battery. how about the current
1amp per hour. so a 2500mah cell will take around 2.5 hours
What r u building please?🤔
Charging station
UP your volume

Tough break. I fortunately did not have any issues like that and came out very well with what I did buy.
I fuse my tp4056 so incase of putting in a cell backwards it just pops the fuse
Good idea... If I end up reworking it I might do something like that. But for now I just say "positive to the top" over and over and hope my hands follow my instructions 😂
@@havinfun4014 I'm the same way but once and awhile screwed up that's why I went to fuses
@@havinfun4014 I believe some TP4056 has reverse protection built in. Might look into it to be sure though.
@@wmonte75 not these ones lol 😂... I did one backwards, both red and blue LEDs came on, but after you remove the cell, that board doesn't work anymore...
those tp4056 have reverse protection ,true there is a module that don't but its shorter we don't see it much because its about the same price.
