This video is 9 years old and still relevant for newbies like me 😁
Excellent 👌 Video sir. As I've just bought a charging board and a decent balance charger and needed to know how to work that thing 😂 plus I didn't even want to attempt reading the Chinese translated instructions 😆
So thank you 🙏
Love this video. To the point and explained a question I had about charger not being able to match mAh. Thank you
sir, this is one high quality, well made video.
Great video. Very explicit and detailed, thanks for posting.
Excellent video and editing, thanks a lot for taking the time to do it.
Thank you for the video I was not sure on the balance board what order to use. Now I know it doesn't matter they are all the same. The math was much appreciated too thanks again.
Best informative video about charging lipos ever. Thanks man
Yea, if your intention is to cause a fire it's your source
Thanks for the tutorial. Several sources are claiming you can charge different capacity lipos, in parallel, as long as they are the same cell count. I believe this makes sense considering the charger is measuring voltage, not mAh.
Perfect step by step instructions and easy to understand ! Thanks very much for sharing...
Thank you for the straight to the point information!
Great video. Gotta say I was pleasantly surprised with the quality and content from what I was expecting with a lower view count video (only low for now!) Im sure that will rise!
Wonderful, clear tutorial. Thank you!
Thanks so much, great job explaining this and great diagrams. Not too long either, straight to the point. Appreciate it :)
I use the same parallel adapter. It has been a fantastic way to speed up charging.
Nice vid, crystal clear explanation
Excellent. Perfect. And thank you!
Really good video dont stop this is very well done
Amazing tuto!!!
Thanks for the video =)
Cheers mate. Well done 👍👊🌟🏅
Excellent tutorial thank you
Excellent video!! Thumbs up!
Nice, succinct video, and I enjoyed the music.
Short and on point without any bla bla bla. Thump up
This is really helpful...thanks
Awesome video! Informative and great filming job. Legit!
Great video, thanks. Was never sure if the charge rate could be upped to the total of what you are charging. Like a dummy I've been charging at the rate of the lowest ah battery and wondering why it's not saving me any time to parallel charge. It should be pointed out that it's a good idea to let the battery cells of all the batteries equalize out for a while after connecting them to the parallel balance board and before starting the charge process.
Very good video
Great succinct video - thank you.
And thanks again... 😝 forgot what to do after my last comment!
Hi, sir , thanks for sharing very useful information
Awesome video. Where do I go to find a balance board for my charge.

"How to Charge Multiple Lipo Batteries With Just One Charger"
First 20 seconds: "this is not a guide on how to charge batteries..."
Awsome video and editing... I do agree with Titus... music can be tone down to soothing elevator music!
thanks great infomation, but i got 1 question! Is it also possible to charge 3 or 5 battery's at the same time, or does it need a even number to balance each other out?
Thanks for the info! The bkg music on the other hand...
it was 2014.. a weird time
Excellent video, thanks very much, I learned some things about using my parallel board from your video and it is much appreciated. Have you tried or do you know, can you use the board to put multiple batteries in storage mode as well? Often when I come back from a day of flying and I have lots of batteries I want to put in storage mode, was just wondering if being able to use the parallel board would allow me to put multiple batteries in storage mode and cut down the time :) Thanks again for taking the time to do this video, much appreciated. Cheers, Scott
Very good thanks.
great video ty
Nice video and I would add the following from other tutorials:
1. Step one - measure the voltage of each cell of all the packs. The cells of the packs should not have more than 0.1v difference, if they do those packs should be charged separately. This is a recomandation on many tutorials. Example: une pack has 3,75v/on the most discharged cell, the other cells on the packs should not excede 3,85v. that's 0,1v. The reason for this are the higher current exchange between packs when in parallel as explained in the following steps.
2. If the cells of all packs have more than 0.1v difference we should connect first only the main cables( the discharge, power cables) of the packs, starting with the pack that has the less voltage.
3. After a few minutes, during which, currents up to 10 Amps! depending of the voltage differences, go from the highest voltage packs to the less voltage ones. That's way beyond 2C of charging them from the other packs, thus the need for less than 0,1v difference as the currents rise if the differences are higher. Then we connect the balancing plugs, after minutes. Why is that? Because after some minutes the packs have come to similar voltages and the exchanged currents dropped so it's safe to connect the balancing plugs.
4. The number of cells should be the same, as the charger see all the packs as one huge pack with the same nr of cells as each pack has. The capacity doesn't matter. If one pack reaches the selected cell voltage, it starts delivering current to the other cells of the packs until they reach it too. Thus the capacity can be different.
5. Start the charging process at the courrents explained in the video. Multiplying the current you want to use with the nr of packs.
6. We should select lower current than 1C/pack because the packs have different internal resistance and although we calculated that the lets's say 8A current devided at four 2000mA packs will be 2A/pack(1C) some packs might receive beyond 2C and others half a C because of different internal resistance.
Learned all of these recently after 15 years in the hobby, in which time I've always charged my lipos after flight (big mistake) to have them ready, and stayed charged all their life..a short one, 20-30 cycles before puffing and dropping in power, when others get 200+ cycles. So, no more staying charged more than a few hours from now one for me, and following the rules including the parallel charging ones described above.
Just a quick question do you need to plug the balance lead in at all ?
The reason I'm asking is most of the balance leads on my batteries are chewed up due to crashes.
question...because i will be using a parallel charging balance board do i have to set my charger on to " balance" versus regular "charging"? cause as of now i when i charge one pack at a time i charge under "charge" versus "balance" you know what i mean? thanks for any help you can provide. awesome info video BTW.
Hey I'm building an electric longboard and I want to use this balance charging board to connect two 3s batteries together to make charging easier. To make the entire wiring setup easier, I'd like to then draw power through this board, which will then power my ESC and then obviously in turn the motor. So basically, my question is, with an 85A ESC and 60A motor, will this board screw me over since I want to draw so much power through it. It says max is 30A. Would I be able to draw power through it to the ESC like I described?
great video! But can you use two lipos where one is for example 3.6v per cell, and the other is 3.8v per cell? Will this be a problem?
thank you very much.
imax B6 B6AC balance charger ,
14.8V 4S 1500mAh 75C Battery XT60
Power Genius PG Parallel Charging Board Supports 5 Packs of 2-6S Lipo Battery XT60 T Plug - XT60
can I use above ? Please advice.
how do you know if you need to flip the balance connector? do you need to flip them on every board or just this style?
Excellent video but what if i'm charging a 2200 mah my charger maxis out at 6.0 amp can i use that amp to charge it?
great video, as someone said before.
Thankyou ❣️
hey so i got a dynamite vision peak ultra lipo charger and i noticed it doesn't have a lipo balance port thing how come its made like that? is it safe to charge a lipo can i solder a balance port ??
what is your charger? thanks for the video
this makes a slow charger even slower, right? the reason my fast chargers are slow is that the balance discharge current is limited to .7a, if i try to use parallel charge board it will make charging my batteries even slower if i want to balance them. great video though, i always wondered what these parallel boards did
can i charge two 3s batteries connected in series using one of the xt60 connectors on the charging board and two of the 3s balance lead connectors
Hi can you discharge using these Parallel Charging Board ,to find out the mah.
With regard to new batteries and conditioning, can you discharge in parallel also
So if you have multiple batteries to charge and they are outside the 1amp difference how do you get them to roughly the same voltage so you can parralel charge them?
I have multiple batteries that are same cell count/same MaH, but all different brands with different c-ratings. Can they still be charged together?
Good basic information. If your charger can charge the full amperage don't. Its best to set your charger at .8 the total charging amperage. This ensures longer battery life.
I think there is a lot of hearsay involved with LiPo batteries. I often charge at double the amperage, I've left batteries fully charged for over two years, they are still going great since I bought them in 2014.
@@hippopotamus86 Leaving lipo batteries full charged is a dangerous and terrible idea - that ain't hearsay buddy.. that's fucking physics!
Do the battery’s have to be at the same percentage before you charge them or does it not matter
I’m new to this, and I have a question. Here goes:
I can charge my pair of 2s 3200 mah batteries no problem using a parallel board. Works great. When I hook up my pair of 2s 5600 mah batteries though, the charger says check batteries, disconnect. I can’t figure out why! Any ideas?
how would you get the batteries to around the same voltage? is there a fast way to do it?
World you charge two 2s 450s at 0.9 amps ?
It's taking twice as long as it does for 1 battery I thought it was supposed to be quicker. Missing something I think .. what do you think?
Can you use this for large 36 volt scooter batteries?
can you tell me which brand parallel charger board that is ? thx
My Batteries have the 4pin white connector but lack the XT60 connector. They are 11.1V Lipo batteries. Will this method work for me to charge multiple or does it need that XT60 to work?
Thanks for the tip I was super confused and it would take forever because I would only do one batterie at a time
Great video! But isn‘t it possible to also charge batteries with different (!) capacities? As long as the voltage of the different packs is the same, when connecting them, it should be possible with no problems. Imagine two connected water tanks with different volumes but same filling level..
Have a nice day!
holy shit! AWESOME MUSIC CHOICE! high school art class!!!
what about putting them into storage mode? how to calculate amps, are they the same?
Great video !
Greetings from Ukraine !
my charger can max at 10amp and i have 3 5200 mah 4S 10c batteries. should i discharge first every time i charge or should i go ahead and plug my 3 bats and rate it to 3 amps or 6amps or 9amps? im trying to do your basic math im thinking maybe i can charge faster at 9amps, 3 for every battery. am i making sense?
Is it safe to discharge the batteries through that board at a high discharge rate near max rating?
I have 4 lipohv 2s batteries I want to balance charge how many cells do I charge it for 8s?? At 4amps?
Thanks for this helpful guide!
I have 2 packets 5200mAh 3S. Normally i charging one at 4.0A, when i connect two is this good if i chargé tchem at 6.0A? Thank You!
If you gave 5200 mAh, the correct charge rate is 5.2 Amps (if the battery states “2C”) that’s means it can handle twice as much charge amps rate which is 10.4 Amos charge rate. But that can shorten your life of your LiPo. Charging under the required rate is okay, and actually better for the battery. I have had LiPo’s for 10 years and a they still work as great as they did when I first bought them.
For example:
3000 mAh (max 3 amp charge rate) unless the C rating is 2C then you LiPo can handle up to a 6 amp amp charge rate.
Hope this helps.
Ok those are 2S batteries ... ok, so you should always charge at 1 amp per battery? So if I have five 1.3 3S batteries, I should set my charger at 5 amps 11.1 volts (3S)? thanks
My battery is 9.6V 11.7Ah LiFePo4. What setting should i use please. I keep getting low voltage or high voltage. What setting should i charge it? It is 27 cell battery. What should my mAh and V be on my charger? Please help.
Okay... So I guess Battery 1 and Battery 2 should be similar/basically the same voltages?
B/c as soon as I hooked up my battery's balance connectors, they started getting hot as a crap ton of current flowed through them and started balancing cell B1 Cell 3 with B2 Cell 3.
Is this correct? B/c if so then this isn't very handy unless you're sure your packs are all "charged" to the same voltage.
So for instance if I have 4 5200 mAh (5,2) 3S batteries that I want to charge at the same time, how long will it take to fully charge at 5 amps?
Where can I buy the balance connector and the placket ?
m8 im having equilibrium and this board is showing info just as just 1 lipo is connected. cables are allright, can you suggest if the equilibrium evo 90w is supporting this? or having different issue?
can we use the hobbyking ec06 charger
Can i charge two 3s batteries connected in series on this board?i have connected two 2 3s batteries in series so i can get 24 volts my question is how do I charge them together is it possible?,what do i put on the charger should I charge them as 6s or 3s,should I multiple the mAh by 2 or does it stay the same,sorry for my English
Hi ,
After seeing the video on CZcams I decided to challenge you with a question.
I use a battery pack for my lifepo4 battery 40152S 3.2V 15AH 16 cells, the battery pack is serially connected, ie 48V, and controlled by internal BMS.
Since it is not possible to verify the integrity of the BMS controller and it is not possible to check the cell balance.
Recently I was trying to test the necessity of using BMS when I saw your video and decided to adopt your solution, that is to divide the 16 cells into four groups in which each group has 4 cells connected serial.
1. Can the configuration you are viewing match the type of battery I am using?
2. Can the charger you use meet the configuration I want to perform (4 sets of 4 cells)?
3. Last question, is there a simpler, easier, and more quality solution that you know or recommend?
Thanks,
Abe
what if u need to balance charge more than 6 18650 batteries? how do u set it up? because the max u can go is 6 isnt it?
can i do same process but using Life batteries?
How do I know which XT60 port belongs to which Balance port ?
I have 7.4v /2.2 amps = x3 So should i use 7.4v and 3amps? one amp for each battery ?
I've read on other websites that its ok if you have different capacity batteries as long as there isnt a huge difference.
The voltage on every cell of every battery needs to be checked before you do this, and all cell voltages need to be with 5% of each other. Parallel two cells that have voltages far apart, and you'll be dumping voltage from the higher cell to the lower one at very high current - which can destroy your battery.
Parallel charging is handy if all your batteries have been storage charged to about 3.8 volts per cell, and you want to charge several batteries at once.
so at 4:10 when the charger displays individual cell voltage, from which battery is it measuring? Also, does each battery need to be at the same level of discharged state in order to parallel charge safely?
Bo Han the cell measurement is no longer an actual single cell being measured on any one of his lipo packs, but rather a collective value of a particular cell number of every connected battery combined. so for example, the second value on screen is the combined voltage as a result of parallel connecting "cell 2" from battery 1, 2, 3 and 4 all together. so if i leave all four of his 3S 1600mAh batteries connected to the board but in stead of hooking it up to a charger i use it on my RC, i would still get a nice 12,6V output but the capacity of that would be 6400mAh. and yes, it would be extremely dangerous to mix fully charged and fully empty lipos together because the second that connector makes contact, all the connected batteries will try to rapidly discharge into the empty one, most likely melting your board, probably damaging the full packs by excessive discharge rates and possibly even starting a fire at the empty pack from the extreme charge rate.
This this cause the batteries to take longer to charge?
Because the batteries have to be the same capacity for this to work, will a 2200mah and a 2250mah battery charge together or is the difference too much?
the slightly smaller battery will charge slightly faster and raise its voltage a bit faster... but as the nice guy in the video explained they will try to balance their voltages all the time... its like having compleatley drained battery and a battery that has like 10 seconds of flytime left... so yea you can charge them both safely... in theory you can also charge 1500mah battery and 3000mah abttery together... just sink the board into liquid nitrogen :P
whats if i want to charge with my skyrc 1200 watt power supply? do i need something else than just a parallel board and my power supply?
lipo need to be charged constant current, constant voltage. When finished it needs to switch off. A power supply will supply as much current as the battery calls for, so not cc. It also will not switch off when finished. To get the maximum life from your batteries, they should only be charged at 1c.
Tell me how I am going to charge a single lipo cell? Thanks.
What if the batteries only charge up to around 15.2 to 15.4 and not up to 16.8 on 4s batteries 🤔. Im charging 6 1000mah 4s batteries and I set the charger at 6000mah and 6.0 amps. Well, the charger didn't like that and after about 45 seconds of charging the screen dims out and it stops charging and beeps. So, I guess its because my charger Max's out at 6.0 amps.
So, I set it at 3000mah with just 3 batteries and set it at 3.0 amps of charge rate and it charges for about 35 minutes and it will say they are full at 16.8 each with all 3 connected. Then, I will test them out 1 at a time and they are indeed not making it to 16.8 but only to around 15.4 per battery? Which is around storage amount. Im wondering why it is doing this? I then still have to finish each battery one at a time up to 16.8 a pc from 15.4. Each one will make it to 15.4 identical to the others. Also important note...I did have the charger set to balance charge not storage charge so I don't know what is going on. Any help would be great if you have any ideas what is causing this. Im thinking I need a bigger charger with more capacity. The charger is a B6 V3 smart charger rated for 1 to 6 cells for lipo charge rate 0.1 to 6.0 amps discharge rate 0.1 to 2.0 amps and it does 2 3 4 5 and 6s. Thanks in advance for any ideas 💡 😊. Take care and talk soon.
Hi, is it necesary to be the same mAh capacity?. My case: 2x1500mah, 1x1600, 1x1400? Thnks for the video. Wait for your reply.
+Iosif G , Same question here! I don't think it is advised, but 'd like to know it before trying and possibly damaging my lipos
I realise this way late, but for the sake of other people that may come across this. It is absolutely imperative that they are the same capacity. If they are not the same capacity it is quite likely that batteries will explode or balance wires will melt.
How come you have charged 3s and there are 4 packs?
So if I charge two 2s 7.4volt 65000mah batteries I charge them on the 2s setting at 14volts? But my charger only goes up to 6amps?
I beleive amps and volts are different
...
To charge a 6500 Lipo, use 6.5 Ampere (= 1C), so your charger barely handles one. I wouldn't recommend loading two of them simultanously, it would take ages. You should get a better charger with 100W / 10A charging power.
batteries have charge and discharge rates i have a 20 amp hour 12 v battery but i cant charge it at 20 amps that would be like 240 whats through the battery wouldn't be good. you have to charge the battery at whatever the charge rate is for that specific battery the amp hour is just the capacity
lisen kaci hi, so I have four 2700 mah lipo battery charged parallel using a paraboard, my charger is a 60watt , and has 6amp capacity, so I set the charger to 6 amps to charge the 4 lipos in parallel, but during charging it displays only 3 amps, is there something wrong with my charger or do I just dont understand the math on charging lipos. thanks
can i charge three at the same time?
Hey i have 2 4s lipo battery, 1 is 6000 mah and the other one is 4000 mah
There’s no problem charging them in parallel, due to the fact that they’re not the same MAH capacity?
Im charging at 6.0 amp
I forgot something else the batteries voltage is 14.8
If cells connected in parallel equalize. Does that mean they have to be the same voltage? Because if one cell is 50% and the other is 10%. Wont the 50% battery start charging the 10% battery at full discharge current??! That is bad because we are only suppose to charge at 1C.
That's why you should only plug in batteries that are within 0.1v difference each cell.
