Hi Jehu, thanks for these videos. I just scored a bundle of 64 laptop batteries for 120 $ here in France which I'll receive next week and start dismantling... got my iMax B6. Time to play, test, build, think, learn and basically make them baby steps towards grasping what the lectricity thing is all about ! Yeeha !
Thanks again for the inspiration and education !
Keep on trucking ! (from France)
+MakeFix Everyone is scoring batteries these days, except me :(
It's a good thing that cell was nearly full. You don't want to push 5A into a single 18650 :-)
I know you are
I charge 2 packs of 8 cells in parallel and run them in series by using a 2 position 4 pole switch.
I use a RC charger and am running LiFePo4 cells which aren't fussy about balancing after they have been bottom balanced.
This set-up is for an e-bike, so it's relatively simple.
RC chargers are handy to have around be if you like messing around with batteries.
You buy a charger with built in balancing and completely bypass it when actually charging the batteries. You could get massive currents between batteries putting them in parallel like this if they are not balanced, potentially causing a fire.
By my experience all cells tend to be at the same voltage after some charging. I tried disconnecting them and measuring the voltage for each cell and they are almost the same, with variations of 0,1V. This variations could be dangerous, and I recommend charging them in parallel to 4.1V and then balance-charging them to the max. The video is not a "healthy" procedure, but it's a trick to charge faster.
@@lucioherediaparaja359 What's really interesting is that since my comment 6m ago, I set up a 4P4S solar panel charger battery array and after ~180 charging cycles each parallel array was only out by ~1-5mv from the others, which blew my mind. I was expecting much larger deltas in just a week and having to balance it manually dozens of times during those 6 month. The cells are all old salvaged ones too.
@@Ziplock9000 that's amazing! Are you using a BMS? Could be a good way to extend it's lifetime.
@@lucioherediaparaja359 I'm not using a BMS and that's why I'm so confused. The plan was to manually balance them once a week with my CellMeter 8 and/or iSDT BatteryGo BG-8S. I just don't understand how they managed to stay in balance for 6 months to such an incredibly close tolerance with no balancing at all (automatic or manual).
@@Ziplock9000 I see! Thanks for sharing this. I think that those mV after a lot of cycles can get bigger and cause a problem, that's why people use BMS. But if you're okay balancing them once in a while I suppose it's okay :)
First off thank you for all that you do. Helping Puerto Rico out shows your true motivation which is helping people out with no hidden agenda. I'm motivated by your path and appreciate your mojo.
I've been following for a while and starting to get pretty deep into sorting my 18650s out after my first order of 42 old laptop batteries. Now, I got my hands on 4 IMax B6 chargers and I'm confused on the settings. So I got the safety timer off and setting changed to LiIo at 3.7V 1.2A(charging 3 18650 at a time in parallel). Why can't we set it to 4.2V like the 18650s are rated for? Will the charger just stop automatically after it reaches 4.2Vs? Just figured the charge controller would let you choose the full voltage charge rate of 4.2V instead of just giving you the option of LiIo and the amps its pushing out.
Again thanks for the motivation and what you do! #nerdout
Cells voltage is 3.7v nominal. It will charge to 4.2v by default but you could modify on the b6 I think
You can change the LiPo settings to LiIon settings by going trough the user set>enter then set the battery voltage to 3.6 from 3.7.
it doesn't matter... it will get charged to 4.2V either way...
@@Tonyplat98 It actually does because the final charge voltage for 3.6 nominal cells is 4.3V
@@justin456 4.2 for li-ion
Li-ion is better for Li-ion, the charger stop at 4.10V
Hi Jehu! Thanks for your videos, I am learning a lot and getting quite excited about making my own powerwall. Question: I understand the 5 amps for the 16 cells, but when you put only one cell, wouldn't that overheat the cell? I mean, in the video the cell was already charged, so very little current flowed through it, but let's say it was discharged, wouldn't that damage or at least overheat the cell? Thanks a lot!
Be aware that setup is not as safe as Jehu makes it sound. The nice sharing of current will only happen if all the cells are in reasonably good shape. If one of the cells connected in parallel develops a short circuit, the charger as well as all the other cells will try to dump all their energy into it and there will be fireworks. It would be better to have a fuse between each cell slot and a common bus wire.
So the ratio benefits/risks is quite high, unless you insulate/isolate the charging location :))
Don't use the LiPo setting for Li-Io batteries.
There are actual settings for Li-Io batteries in the Imax charger.
In the menu go in to:
User Set - Program.
Hit Start/Enter button.
The screen then shows only one of these battery types (LiPo, Lilo, or LiFe) and V.Type.
Hit Enter button.
The voltage setting will start flashing.
You can now change the voltage settings using left and right (Dec. Inc.) buttons.
You'll see 3 different voltage/battery type options as you press left or right () buttons.
3.3V - LiFe
3.6V - Lilo
3.7V - LiPo
Select your battery type and press Enter button to confirm Voltage/Battery type.
Now press Batt.Type/Stop button to exit Program menu.
You'll be back at the User Set - Program-> screen.
Press Left () arrow 6 times and you'll scroll through 'Program Select' Screens:
LOAD DATA, SAVE DATA, Pb BATT, NiCd BATT, NiMH BATT, and finally one (LiFe, LiPo or Lilo) battery option depending on what you entered on the User Set - Program-> Screen.
Press Start/Enter to select (Lilo, LiPo, or LiFe - only the battery type you selected on the User Set - Program-> screen will be shown)
Next you'll see:
(Lilo, LiPo, or LiFe) CHARGE depending on what you chose at User Set - Program-> Screen.
Press Start/Enter button and charge amps will flash, adjust up or down as needed with () buttons.
Press Start/Enter again to confirm your amp setting and the voltage selection starts flashing.
Use () buttons to select voltage/cell configuration for your needs, the total pack voltge and 1S, 2S, 3S etc will change together.
You can also press left (
Here's something interesting about this type of charger. The original one won't charge more than 1S without the balancing leads, but the clones/copies will. That is, the clone will allow you to charge up to 6S pack (whether it has a BMS or not). The original one can also charge Lifepo4 (although both allow you to adjust the voltage parameters). The original one costs twice as much. Some clones have very cheap capacitors so they burn out quite quickly.
Vegemite is the only thing I would assume to teach you about. Firstly try, using butter or margarine on your toast. Then smear vegemite thinly over butter or marge. Taste is not overwhelming that way. You have taught me a lot. Thought Id return whatever I can back. Thank you
hey, just thought you might want to know that the link for the battery holders are for AA size. 18650 holders are recommended item at the bottom of page.
i charged a pack of 60p 1s of random capacity cells in parallel that i built and tested the capacity wich was 78ah at 4.2v it took ages and the counter rolled over a few times but it charged it no issues
I admire your patience when it comes to charging 1s60p using only 5A charger. That is only 83.3mA per cell, no wonder it took forever :)
An easy way to charge a lot of cells at same time in parallell is to use small magnets and welding rods.
Just put magnets on batteries poles and put weldingrods to magnets. Connect with crocodileclips to charger.
can you show how to do this and list a source for magnet and weldingrod parts? sounds cool!
Great idea... suggest him ..
dork
The more I learn about electricity the more amazed I feel. I know motors have magnets, but dumbfounded how passing electricity through magnets can work.
How does it not weaken the magnet, or create resistance and heat? Amazed.
If you have LiIo batteries, you have to set it in the presetting level and instead of LIPO showing up, it will be LiIo showing up by default.
Hi all
0.3A or 300mA is the best SPOT to charge 18650 batteries safe @ home, thanks for the tips.
I have one Imax b6 mini and i charge 6 cells @same time @1.8A 3.7V 1S and never get my batteries hot.
Like u said on another video I will let the batteries sit for a couple of weeks and start my projects.
Nice power halls behind you 😉😉😉
SHopuld i decide to go EITHER with the Imax B6AC v2 OR with tp4056 modules ? What is the safest way to go ? Can i mix both ? It's to repurpose powertool 18650 cells (LFDAHA) thanks i love your channel, that's one of the channel that got me into electromechanic.
Hi, if you get the low voltage warning and you can't charge them. Select nimh mode and charge them till they get to about 3volts then switch to lipo mode. Regards
It also has a lithium ion battery charging mode pls tell them .. u just need to dig in the settings. I mean the prog menu . U can change the li po to li io which is lithium ion ..
Very good video on how to reduce the life expectancy of Lithium Ions... Dude you really need to do some googling about Lion chemistry and charge curves. Apparently you need to look up how your charger works too. Otherwise... Good vid!
can you make comparison video with imax b6 genuine and fake, to measure them with multimeter and show us differences in results?
I can do that for you but i don't know when i'll get around to it. I know for a fact that the fake charger charges a lot slower and it's voltage can be wrong... for example I have a 3S battery which full charged should be 12.6V and when I charged it with the fake one and measured with my fluke 87-V multimeter it was at 13.1 Volts. That is dangerous and is killing my cells and that's what made me get the genuine charger. After I discharged that battery and charged it with the genuine and measured with the multimeter it was at 12.599 which is exactly 12.6V. From that moment on i've never bought another fake charger. Jehu recommends the fake ones in the next video but I wish he did not. He has a lot of followers and they listen to him but fake chargers no bueno....
@jehugarcia: why dont you put the maximum of cells in series and use the imax bms to balance each individual cell? Just add a few sensor cables and the bms plug, wouldnt it work?
This IMAX B6 charger can only charge up to 6S Li-ion cells, or 25.2V, so that's the reason.
It has only bms plugs for UP TO 6 cells in series. which is 25.2V when fully charged. Far as I know.
I dont understand why that beep sound came during charging(original imax) with 5A, i dont think we should not charge with 5A with one cell...? what is max Amps that we can charge per one cell. i do remember 1 cell can charge with 1A 4.1V. correct me if i am wrong.
Hi, Jehu Garcia! I really like your videos! I have over 400 Cells that laptop battery withdrawal. I intend soon to develop a fusca or fiat model 147. Best regards, Rock Bomfim - Rio de Janeiro - Brazil
charging the 18650 on lipo? What about the Li io setting on the charger, seeing these are 18650's? I thoughts LIPO and LIFE was for the foil pack batteries
Mr Garcia. I really appreciate all of your videos, they have inspired me to start building a battery pack for a project I'm working on. I am having a slight problem though. I put together trays for charging a bulk amount of batteries like you recommended. The batteries I've got are already at 3.8v and have connected them to my imax b6. When I start charging them, it shows charging for only a few seconds and then says fully charged. Am I doing something wrong? Why won't it charge to 4.2 or at least close?
I have different charger that is designed for lithium ion cells like the 18650 and it shows the lower voltage and will charge them to 4.2v. Any help you can give would be greatly appreciated.
Hi Jehu, following you from Sweden and like your battery projects. Do you think this holders are suitable for a power wall in someway? Maybe have 2 facing each other on their backside and some heavy gauge wire or busbar soldered on. All this just to not have to solder on the battery's. What's you opinion, and can the holders manage the current? :) thanks anyway, keep the battery video coming.
the battery holders you link in this video are not correct my man i just received them and they are the AA sized holders. I think they may have been correct for 18650s when you posted this video and the amazon seller may have changed the listing or something since then. long time subscriber keep it up you are inspiring.
I did not know that your charger lipo can charge lithium ion but does it matter?
Do you check the voltage prior to dropping them in the iMax?? And if you do what's you decision rule for what you keep and don't keep?
Thanks for the guides, currently ripping out old laptop batteries for experimenting and I got one of the clone chargers for this.
Hopefully nothing explodes!
You can also set those chargers to LiIon, which makes essentially no difference. Except that it changes the nominal voltage to 3.6 V per cell, which I would assume effects the capacity readings slightly (about 3 % more) since I believe the measured capacity is adjusted to 3.6 V. Meaning if it pulls 1 amp for an hour at 4 volts, it would actually read 1111 mAh since, at the nominal voltage of 3.6 V it would need 1.1 amps for an hour to get the same amount of energy. I don't know if this is the case, it's just an assumption, since that's what I would consider the most logical. I guess it would be easy to test with a lab power supply set to different voltages...
Anyway, if anyone knows exactly how these chargers calculate mAh readings, feel free to reply to this comment. ;-)
Hey Jehu, really enjoy all your videos. Stay up my friend. Do you think I could run 2x16 battery trays in series? Which would make 32 batteries in all to charge with the IMAX6 CLONE? Thanks
Were you able to do it?
It requires 16A but Imax can has 5A, if try to charge 16 cells with 5A it will take more hours to charge all the cells
It worked out better with one 16x cell tray. Also works better if you leave cells in tray for a day before charging, that way the voltages of each cell evens out. And that helps with having even voltages while charging. Which is key.. Thanks for replies and good luck with your battery projects
Hi can I also do that on Nimh batteries? if can then it is possible to charge 4 of them at once? Thanks!
What you didnt mention is that if you have 16 batteries hooked up, you may have to go through 3-4 charging cycles before they get to 4.2V The charger will only run so long then bail out and you have to start it again. 16 batteries starting at 3.5v will easily take 3-5 cycles to get them all to 4.2v
joeventura1 hey buddy can u help me im charging 16 cells at once the same shown in the video I have the imaxb6 and the holder and all ready all my 16 cells are at 3.7 v but my charger is showing 4.2v though it has not reached the Input current i.e 5 amps starts decreasing like 4.9,4.8,4.7 and after some time it was charging my 16cells at 2.9 so I turned off the charger plz can u help me!
Run it through the full charge cycle (it may error at the end) check voltage of each cell, if they aren't all the same voltage take out the ones that are lower, wait 20 mins and start again, keep doing this until all the cells are at 4.1 or 4.2 volts. Then you are done. Through each cycle Check the batteries for heat, if any heat up, throw them away. Don't leave them charging unsupervised.
joeventura1 but what about the input amps which decreases on its own? That would take evenore time for. Charging
Thats the safety built into the charger, you can't change it
joeventura1 can u provide ye email through which I can send you some pics so that u can guide me properly please that would help a lot!
I used to imagine(by logic) how to charge single cell 2 or 3 or evn more together . However, yr video made my imaginary idea cleared. Thanks.I like most yr vids coz very simplified & explained th terms for evn a lay man like me. :-D
Hey can I ask you something. Why 16 cells? I mean why not 20 or 24? isn't the charger going to see it as 1 cell anyways? What is the difference?
Excellent, how long does it take for a 2500mah 7.4 2cell battery to be charged with this full charger ???
promite is by far the nicest imo. Good vid, was exactly what I was looking for so thanks.
Hey. How to check capacity of 18650 battery. Using discharge functions of b6 charger. Should its discharge test on 1A or 2A witch is correct Amp?
I had no idea all the chemistry involved when i started using these batteries. If it wasn't for your videos, I would be lost!! But I have a few quick questions. I like to build those mini boom boxes, and a few of them are now using 5s BMS boards. I figured, since it is almost impossible to get a 21 volt DC charger here in the states, I would purchase a few of the Imax b6-s. Only problem, the person I give the box to would have to charge and than play. I am sure I am wrong, I am just learning...LOL. My questions-- Say I want to use the Imax to charge my 5S. Are you saying, when I go to charge all 5 batteries.(plugged in like you mentioned here). I would set the Imax at 5amps, and 3.7 volts or 1s."4.2 volts charging". The Imax will charge them all at 4.2 volt 5 amps, it see the pack as one big Battery? If this is the case, couldn't I get away with a purchase of a 12.6V dc charger, or even a 4.2 dc charger and it will still charge my pack fully. I have always been told-- Example, if you have 5s-You make sure to purchase a 21 volt charger, 4S-16.8Volts, 3S-12.6V, 2S-8.4V and 1S-4.2V(all 2 amps or higher). I can find affordable and abundant 4.2-12.6Volt charges all day long. Would save me some money. Or does the Imax only work this way if you do not have a BMS board?("I didn't see your BMS video till after I had already started using them..LOL") You have NO Clue, how much I have learned from your Videos!!!! Very Detailed!
Sorry I don't really understand your question
Sorry, I wrote this question when I first started my Li-ion Research. I was not that well versed in these batteries. I guess in "JoeMan Terms", I was asking, if you can use a IMAX B6 to charge the BoomBox Battery Bank. Answer: ("Yes")Than I was wondering if you could also use the Imax b6 to power the system, so I wouldn't also need to purchase a 21 volt charger. Answer ("No"). The Imax b6 does not provide the type of Voltage needed, to power the system. So I would have to purchase a separate 21 volt plug(not charger). Something like a Laptop Battery supply.
I ended up, rewriting my schematics to include a SDPT switch, and 2 separate plug-ins. Now I can run on Battery power, or switched and use a Proper Power supply. Later on in the power line, I have a master power switch with Voltmeter. (parallel charging will not work in my situation)-BMS charging the batteries, and than switched to DC power when needed.
The other questions-Say I have a 5S Battery Pack. Is It possible to charge that pack with a 3S charger. Would it still charge?, just slower than a 5S charger?. (Only in Parallel) My batteries would be in Series and would not work.
I want to Thank you for all of your Video's. I have Major OCD, and I wanted to make sure I got the battery system right the first time. If I had to guess, I have 2 weeks, 24/7 research on Li-Ion Batteries. I have learned the most from your Videos. I had to grasp the differences in parallel charging and series)Newbie here 200%, but learning!
Thank you!
Thanks. If I have a motor that draws 25 amps and i have a battery pack that is 6s40p - that is 6 cells in series with 40 batteries in parallel for each cell. That is a total of 240 batteries. How many amps is each battery discharging? I would like your answer to be in a formula. Thanks and you have a great channel.
+robviolin1 25/40=0.625A
Hi, Jehu Garcia!, The same way can we discharge all 16 batteries in the same setup? Thanks for the nice videos.
Thanks for this video. Since I already own an electric RC, I have the charger....just need the battery holders...soldering job is easy....
Hola Jehu. Estoy haciendo una conversion en Argentina. Uso 18650 para un pack? Actualmente es lo mejor? O sigo con otras baterias?
Hi, Jehu. I'm doing a conversion in Argentina. Use 18650 for a pack? Currently is the best? Or I continue with other batteries?
Yes
It will be usefull to balance charge those cells.What arrangement we need?
So if you are charging 16 cells , what if 1 or 2 cells reach 4.2 before the rest?
Does it keep charging until all 16 reach 4.2 or will the 1 or 2 cells over charge?
Hi! I love your accent! I have a question. I only need to charge one 18650. I really need to have 5A? That seems kind of high. Can you please let me known what you think? Thank! Kimball in Hungary
I take back my previous comment, you are right i had bad cells and this does work well, im building a 14s10p battery, can i charge each cell in parralle with an imax b6 and use this idea? Just use positive and negative of each cell, charge it at 4.10v and repeat 14 times..
Hello Jehu awesome video. But one thing i notice that is not mention is what Type of Power adapter is needed for the incoming Power to the wall? at 5 amps output doesn't the input current amps needs to be Higher?
joseph chrzempiec no, 5A charge for testing is enough
Hello Jehu no what i mean is what type of Power input is needed for the charger to output at 5 amps?
22AWG (american wire gauge) has I believe...a maximum 5Amp of current flow through the copper (I am not an engineer here). The lower the AWG number the larger the copper wire... the higher current potential... this tends to drop however depending on how long your cable is since it needs to transmit that current over farther distances (hence direct current voltage tends to drop over long transmissions and I believe thats why we use alternating current for power grids instead) but yeah for 5Amps you dont want a smaller gauge wire than 22AWG
Hi what’s the wiring for Balance charging 5 series connected 18650 cells?
I have a question about the IMAX B6 when charging 18650 .....Do i have to let it run for the whole 120min,because my doesnt tell me when its full,but it does tell me when the time is up though...Its a 3.7v 2000mah 18650 i have been charging it at 1.5a.
Damn, se me antojó el pan. Muy buen video Jehu. Ya puse a cargar mis baterías con el Imax v6 AC version2, solo que decia 6Amp y mejor lo cambié a 5Amp. Saludos desde Monterrey México.
Hi jehugarcia! Question if you dont mind is it possible to use imax instead charging 16s 18650 battery. I dont want to use bms because i dont know where to get it. Thank you
Que pachuca por toluca mr. Garcia i have an 8cell 24v lifepo4 pack that i would like to balance . My charger only balances up to 6s but it does have the ability to charge 4x6s at once. My question to you would it be possible to balance the 8s pack by doing 4cells on one balancer and 4cells on the other without dissasembling the pack
Actually, you can do balance charging which will adjust charging to individual cell, thus max out the capacity.
What you did will (1 series 16 battery cells) compromise its capacity since each cell will contain different initial mAh, except you 're already sort its capacity.
Parellel charging self balanced"s itself, no real benefit to balance charge if you can just do it in parellel.
I would like to find a charger that will charge 7 or 8 liion cells in series! A 29.4v total. I have a tester for a 8s li ion. But haven't found a charger for 7s. I thought about trying two imax B6 connect one to 4 cells and the other to 3 cells. Or go the crazy route and buy 7 imax chargers! Crazy I know!
Just wondering why you are charging 18650's using the Lipo setting and NOT the Lion setting?
Because it’s the same thing
Ok thanks, i thought the they where different voltages?
So it can charge batterys with 4s holders ? , because i buyed 4s holders instead of 4p by mistake with IMAX 6. Is there any problem with 4s holders with this charger ???
first like and post!! what a first hahaha 😂 😂 I too am in England and find that your vblog channel great and informative.. 👍I have been using my imax b6 since watching you!
Thank you..
I did this method.... all 16 batteries in parallel are stop charging at 3.8v
Hello brother don't you think it's risky to charge batteries on different voltage in parallel, i'm asking because i like your videos and would like to follow your instructions,... i want to build a big battery, but all my cells are from laptop.. i don't know if i'm to charge 16 cells in parallel with different voltage will be problem?. please reply
No problem
Hey Jehu,We are a startup company trying to built an affordable ebike.Got some douts about the batterys.Could u help us clear it?
Did you insulate those wires soldered to the holders? If not be sure not to lay them flat on a metal table with batteries in them?
so what you are saying here that the Parallel linking of the for example 3 (18650 cells) makes the charger dealing with them as one cell, so we can get them charged equally >
my question is :
can I make a 3S battery so each cell consisted of two 18650 cells?
is the balance charge method gonna work on this kind of battery ?
and thanks
Yes
I have a battery pack of 4 18650 batteries in series, What setting do I charge them on? Fully charged they are 16 volts but the charger doesn't have a 16-volt setting. It has 14 or 18. Is the voltage adjustable on the Imax B6?
If the 4 batteries are in series then it is a 4S. You can also have 2 // groups of 2 batteries in series and then it is a 2S. Nominal battery voltage for a LiPo battery is 3.7V, so if you have 4 in series, it is 4 x 3.7 so 14.8V. But 18650 are Li-ion and not LiPo so nominal voltage is 3.6V. Maximum charge is 4.2V per battery, so again total will be 16.8V. In Series, you multiply the Voltage and in Parallel, the Amperage. To extend the life of the batteries, they should be charged at 1C maximum and better at 0.5C so for a 2500mAh battery, you should charge at 2500 x 0.5 = 1.25A.
This is a nice article: www.instructables.com/id/How-to-Prolong-the-Life-of-an-18650-Battery/
i was wondering about the possibility of wiring a large battery pack with a series of switches that allows it to turn from an 8S into a single battery back that is composed of possibly 100 18650's in parallel so that it can balance itself and not have to charge in increments of 6S (max capacity for series charging of a B6), however, i'm wondering if my idea is flawed because now each cell will be being charged at such low maH, it may take forever. what do you think? much appreciated
Just now was wondering on how to balance my battery without balancer and you, sir, gave me an answer. I will also try this, becoue I have no 3s battery safety board, but I think I can handle it with simple Voltmeter :D
You don't want vegemite you want marmite :)
You're wrong. Marmite is nothing to vegemite! Lol!😂
Vegemite is Marmite, it is the same product with different names in different countries
Beware! Caution! The battery holder link is not correct!!!!! It comes up as Double AA battery holder!
Would there be any problems (other than slower charging) with wiring the holders in series parallel? Thinking of doing 4s16p since I already have 4s holders.
Were you able to do it?
@@carlos0celis Sorry haven't got around to it yet. I'll try to remember to let you know.
I noticed on Aliexpress these battery holders have gotten cheap ..like 0.80 each for the 4 holder .So I'm wondering if it would be possible to build larger batteries by combining them..no soldering and it would make it easier to troubleshoot and replace individual cells..
i would not recomend using these housings for larger loads if you would like to get max current out of the pack these holders would cause owerheating and possible fire the connections would have to be made thick or wide as the ones on the pack when you solder it.
The type shown here seem pretty solidly built .. I was hoping to get an idea if anyone has tried this for an ebike.. I know some are using them for power walls.
Love the vegimite, are you used to it now?
What if I put cells of mixed voltages? Let's say some are 3.8V, other 2V or less. Do these voltages magically balance themselves?
And if so, how come it not damage the cells?
A cell that is 2v in this chemistry is a fully dead non servicable battery, if you parallel this with cells that are 40-50% at 3.8 it will try to balance and likely cause a fire without even using the charger at all.
@@justin456 I have to disagree with the first part. I've revived many undervoltaged cells, some even below 1V and most of them are perfectly recoverable. They might lose considerable chunk of their capacity, but they do work just fine.
Took on the vegemite challenge like a champ bravo! My question is i want to be able to charge 18650's from a car alternator which runs at 12V 70A yet still be able to power an inverter at the same time, do you have any ideas? with thanks Andrew from Australia
So, if I have a 2S 4000 mah battery with no balance wire coming out what would i set the charger at? 4.0A at 1s?
I have a problem maybe you hear it first time.i am trying to charge a 3s battery pack using balance lead with my turnigy accucell 6.I get an error something like 'balance connection error' .when i unplug the main voltage wire and leave only the balance wire with my battery it says inverse polarity.now the problem is i do not have inverse polarity.also i checked voltage on balance wire for each individual and gives the correct values.what is going on? Now i just charge the package without the balance wire.
I have over 300 good reclaimed 18650 cells. What can I do with them? Any suggestions?
Can you discharge 16 cells with this charger too? And know the discharge time of each cells?
OK, When you have a battery pack with batteries both in paralell and series, How does balance charging help if you have a bunch of batteries in paralell? What if one battery is exceptionally better or worse than the others?
I have the B6AC v2 as well, and I'm making an array of 6 X 3S4P batteries for a 110v inverter system for camping. (so really, It'll be a 3S24P battery, ideally I'll be able to charge them all at once as they plug into a parallel board.
Am I going to blow my house up?
So, you can not balance charge this way then ?
On the copy lipo charger , 6 cell is the max balance charge you can do . Is there a way to increase that ?
Is there a way you could charge laptop and tablet lipo batteries on the imaxB6 ?
Your videos are great .I really like this charger .Will it charge ncr18650pf mh 12210 in a 10 s configuration .in 4 parrallel ,36v 11.6amp hrs ,block thats in my electric bike?
Hola mr garcia! question! charging DIFFERENT cells in parallel. from different laptop/device batts...? yes..no? safe? thanx LOVE YOUR VIDSSSS!
+Karllito Antonio I do it all the time
Hello! I also had a question about battery connections. I have about 75 LiFePo pouch cells with two tabs each. How would one go about connecting these up? I have an idea to make some clamps, and routing some aluminum sheets between them (1xxx series, for better conductivity). Does this seem like a decent idea to you? Thanks!
Next time when you have the Vegemite spread, sit some Avocado on top. Delish!!!
Don't eat Vegemite eat Marmite we do in the UK it taste much better than Vegemite I tried it when in OZ
If the 18650 LI ION pack has a BMS, would the B6 connect to the BMS input or directly to the battery? Cheers
lipo balance charger works for 18650 as well??
Can't you connect each battery bay to the balance leads?
That charger should balance all of the cells as well, as if it was a 6s lipo
I'm only getting 4.10v charge via the IMAX. I have 3 of them. Either they suck, or... they suck?
Can a capacity test using the Imax unit be done, similar to the test you can do on Kiitokala?
I also noticed I can drop batteries into the Adeaska and it will charge batteries at 1.6 v or that is what is displayed in the display of the Adeaska. Other chargers like the Imax and Liitokala don't charge a battery at that voltage (1,6v)?
I just built this and tried it, but is stopped charging all 16 cells as soon as it reached 5A, the message said CAP so i assumed capacity and i was right, in the settings of the charger you get a safety amp cutoff and its set to 5A, should i change this to reflect the total amp of the full16cells? 35.2A since they are in parallel?
Can you do this with the newer imax v2? Thanks for the info! Also just a heads up, the link for the battery holders are for AA battries. Maybe the amazon seller changed it?
after i charge my battery in parallel can i now put the battery in series without BMS ? or i need to Discharge all at the same time. before i put in series and Charge it? Thank You Sir
Hi My imax b6 will not charge my 4s 5200mah lipo,,,,when I press enter after all numbers are set,,,the charger always reboot itself..can u help?? tq
I don't even know that much about batteries but you're going to charge One battery at 5 amps? I know that's wrong. Now if you had all 16 batteries in there in parallel then 5 amps would be okay.
One battery is a group of cells, so, he's charging 1 battery, in this case made of 16 cells at 5 amps.
Noob question here: What happens when you mixed up 7 batteries at 4.2V and 1 battery at 3.7V in 1S-8P battery pack? Will it charge the 3.7V battery and self-balance the pack? If the answer is YES, then how much will be the charging current that the 3.7V batt will draw from other batteries and if that charging current is still safe for the 3.7 batt? TIA.
In this situation I'd recommend just charging the single cell alone @ 300ma, monitor the heat like mentioned.
What if your battery is under 3.4v, as lipo can only go down to 3.4, if it is lower, the charger won’t charge, but lion can go down to like 2.6v
Hi i have a question.
If you charge the battery with 3.7 volt how is the battery go up to 4.2 like you said. Shouldn't you be charging the battery with 4.2 instead of 3.7?
3.7v is the nominal charge...it does charge them to 4.2v
Hey. I'm from India. I'm making 3s6p 18650 pack each cell is 2000+ mah and I have a b6 charger I don't know its clone or real. So my question is how to charge this battery pack means what setting I do(balance charging) should I charge them on 6A max ??
So how do you know that all cells are balanced or charged the same?
