So do you just leave the charging cord alone and it doesn’t need to plug into anything when running your rc like will it still work in water?

Mine holds 2 LiPO batteries okay and it dies after being played with but one of the batteries is less powered than the other one when I'm showing 8.4 volts the other one still showing 11 volts what's going on

@rossdejager2577 9 лет назад

Very good explanation. It might just be also worth mentioning in this video that if you connect the two batteries in parallel the storage capacity in mAh doubles to 4000 mAh, and when connected in series, it stays the same at 2000 mAh.

@JesseBlum 6 месяцев назад

I got that same exact connector today. Its awesome to use my two 7.4 volts that I hardly ever use anymore because I bought a bunch of 3s batteries.

@TBD_Teebs 7 лет назад

Thanks for this little video! Just needed a quick refresher as to what connectors I had as I haven't driven/worked with my RC Buggy for a while. Just one thing I would mention, with the theory you've given, is parallel basically gives an RC model a longer flight/run time, but the same power. With series as I run in my buggy with 2 2s lipos, it gives it a slightly longer run time but also doubles the power that the buggy can draw. So since my setup can handle a 4s lipo, basically doubles the max speed my buggy can get to :)

@Painless360 7 лет назад

+TBD_TheBlackDog as you increase the voltage by connecting your batteries in series it does mean that the motor needs to pull slightly less current to get the same wattage. This will have the effect of giving you a slightly longer run time as well. Same effect as replacing the 3s with the 4S pack in a model

@guytelfer1353 10 месяцев назад

Excellent video, so the voltage in series connection is what increases rpms while the amps increases the torque in parallel, soon I'm going to do a short video showing 120volts with a current of about 7.5amps and another being 240 at 15 amps , lithiums may be capable of high current using them in a electrolytic fashion, in general lithiums are usually separate to the load through a pcb unlike nickel that just use diodes, consider rewinding the rotor increasing the gauge to handle the unexpected current or unregulating the current

@boy6named6zoen6 8 лет назад

Thanks for explaining the difference to me. I always mix the 2 up for some reason. Had the correct cable to make a 12s out of 2 6s lipo batteries but thought i connect them in parallel instead of series. And hats of for you you are a very patience man with all the questions you get. It's like people can't think for themselves and are looking for a quick and easy answer instead of looking it up themselves on forums or use there brains. I know i went looking for a answer myself but this was a pretty simple one. I see a lot of people in the comments here asking the same question over and over again. I don't have a problem with explaining something to new people in the hobby but i give up on them if they keep coming with the same every time.Do your research self it gives you a much better feeling if you solve the problem yourself with research on forums by digging trough the site.

@Painless360 8 лет назад

Thanks for posting that. I agree too many want the 'quick fix' rather than think the problem through and use the resources available and gain a better understanding of what they are looking at. I try and teach the person to fish, not give them one so they can help themselves next time they are stuck ;) Happy flying!

@YensR 8 лет назад

5:00 slip of the tongue probably, but BOTH arrangements double the power compared to the single battery, because power = current * voltage. I think it would have been clearer to say that parallel gives you effectively a 3s 4000mAh 10C battery and series gives you a effectively a 6s 2000mAh 10C battery, both able to put out the same max power, which is twice what the single battery can do. Maybe introduce the 3s2p / 6s1p notation, too. It would also have been important to say that parallel connection can be dangerous if the voltages of the batteries are different, as they will try to equalise voltages (one charges the other) and high currents can flow in that situation if you do it wrong.

@jackjosephtz3 5 лет назад

Will a BMS help in this case? Parallel charging of similar battery packs

@bartoszsokoowski3659 5 лет назад

Therefore, to obtain a "double capacity powerpack" from two batteries, we should connect them parallel to maintain the voltage of powered circuit?

@robertengelhardt3321 4 года назад

@YensR 4 года назад

Yes, connect them in parallel, you will get twice the run time (or a bit more) and your motor gets the same voltage (but maybe a bit more constant). However, you need to make sure that the voltages of the cells you combine in parallel are very very close.

@MrKillerhaze Год назад

I did this to my kraton 6s love it running 2 3s 7000mah 100c 💪🏼 now I get 14000mah plus 200c of power 🫡 you sir are the best!!

@power-max 9 лет назад

It should probably be important to mention that batteries of different voltages (or cells) should NEVER commented in parallel, while batteries of different mAH should never be connected in series. Connecting batteries that have different voltages in parallel can cause excessive current from the higher voltage pack to uncontrollably dump that charge into another lower voltage pack, as the system tries to equalize itself. if the current is limited, the lower voltage pack can safely charge up and the higher voltage pack can safely discharge into it, and of course the cell numbers are the same (3S to 3S) thats not much of a problem, nor is it in issue when both packs are already at the same voltage and same cell count. The packs can be different capacities since even if one dies faster, than the other pack will help the dying pack out by taking the load off of it, as well as supply the grunt of the power. More technically, it is an equilibrium condition. When it comes to series circuits, the cell count actually can be different between the batteries, however, the capacities MUST be closely matched or else the one pack will discharge faster than the other, and they will need to be continuously balanced, and if one pack fall below 3V per cell, and the multi rotor is trying to draw lots of current, it can be thought of like a short-circuit, and you can see the small dead battery will be *reverse charged* by the bully battery, and it will probably explode! I like explosions, but not expensive ones! (Also I do not like class D fires. They nasty!)

@pochul 9 лет назад

exaclty true ! in parralale u can mix different capacity 1 ah+ 3 ah + 10 ah = 14 ah and if use 7.5 ah ( 50 % of total capacity ) and u disconnect them each pack will still have 50 % of their capacity that mean the 1 ah battery with be remain with 0.5 ah , the 3 ah will remain with 1.5 ah and the 10 ah will have 5 ah still remain ,, many people believe that the smallest will die first ,,, ,, it's exaclty the opposite in serial it's could , but not in parralale ,, u right to mention it

@power-max 9 лет назад

pochul I actually never thought about it in terms of capacity, but absolutely true, considering the similarities of the charge/discharge curves between the same cells w/ the same chemistries; and also the voltage, since the cells will remain at exactly the same voltage when in parallel. Good point!

@alexanderbuckley8975 9 лет назад

+Power Max I would like to move into the parallel configuration for my quad. I am not entirely confident that ensuring the voltages are identical is practical. If I charge the two batteries separately, I would assume there will be small difference between the two given the quality of the chargers. Now the difference may be only negligible, but I would assume there would be some at least short lived high current between the two when connected that would be very unhealthy for the batteries and potentially hazardous if done with every charge and use. Would you have any practical suggestions for equalizing the batteries after charging? Would a large series resistor between the 2 work?

@power-max 9 лет назад

+Alexander Buckley Just make sure they are both the same chemistry, and same nominal voltage or cell count. (11.1V 3S), and that both are fully charged before connecting them in parallel. If you change your mind about charging them separately, I recommend also connecting the individual cells in parallel. The ballence connector gives you limited access (in terms of maximum current) to those points, good enough for this purpose.

@alexanderbuckley8975 9 лет назад

+Power Max My original concerns were related to connecting to separately charged batteries together in-system. I am a computer engineer, I am good with circuits and all that... but batteries do not really fall into my knowledge area. Even for small voltages, I can see there being a large transient on connection. I just don't know if that is a bad. There would not be any sustained high temperature that would be similar to shorting the battery. But on the chemical composition level I have no idea what impact that may have. Repetition of minor damage adds up. It goes without saying there are significant flight time and safety concerns. I have started thinking about parallel charging since doing some further research. It is the balance connector that makes parallel charging not so 'plug and play'. Are you suggesting wire the individual cell from each battery in parallel for charging or during operation or both? I am trying to come up with a solution here that is safe, electrically sound, does not require too much custom wiring or any steps that could be mistaken. I'd like it to be reproducible and simple enough for a lay person (idiot proof). I am thinking now the way to go would be to equalize the batteries in parallel (cell by cell) using series resistors. I can make an assembly that can be attached and switch operated. After that, Y-cables can be connected for both power lead and balance lead, 'forever' keeping them as a single unit for both charging and use. I am just wondering how they would behave, two cells permanently in parallel. It is obvious in the series configuration that each cell behaves differently. I just have no idea what impact permanent parallel connections have on battery life/capacity. I wouldn't be surprised if this even was a beneficial arrangement, one that may reduce the chances of an individual cell dropping below it's threshold while the total voltage still remains over the low voltage cutoff limit. Or one cell's charge voltage could be reached with limited capacity, triggering the charge stop. Meanwhile the other cell could have still taken more charge. Or maybe both things happen it is a trade off, life for capacity. I am just worried about some sort of favoritism scenarios occurring that I don't know about. Like one cell getting pushed to hard in use, hastening it's demise.

Quick question, I can add a 10s4p and a 2s4p in series together and make a 12s. Like the ESC will see 12s or 50.4v fully charged. I'll obviously disconnect for charging them separately. It's for a electric skateboard increasing the voltage DIY. Using stock 10s4p 18650 battery and adding 2s4p 18650 battery. Like going from 4s to 6s on Quadcopters. More power n rpm.

@power-max 9 лет назад

pochul Although thats true, it is not necessarily the best solution, for complicated practical reasons, it is better to use the same cells and manufacture so that differences in the chemistry for them does not cause issues. (which may cause differences in the internal resistance, charging curves, thermal characteristics, etc.) Point is it can be done, although like Painless360 says, not recommended. Only Macgyver is allowed to do that! :)

I tought it could power it for 2 hours but it has 10C written too...so does it mean the battery is capable of 160A? Can I power my motor for 20 hours with that battery? Sorry if it sounds dumb but I'm new in LiPo(s) Thank you again

@Painless360 7 лет назад

The videos in the 'Introduction to Remote Control' covers many of the basics. a 16000mAh pack will provide 16 Amps for an hour, 32 Amps for 30 mins, 64 Amps for 15 mins etc. The 10C on the pack means that it can deliver 16,000mAh x 10C = 160amps max. Not sure how big the wires on it are! :D

Sorry for the long question! But thank you in advance.

@Painless360 9 лет назад

The main thing to be aware of is to make sure that the voltages of the cells in each pack are as close as you can. When you connect two packs together the difference in voltage will drive a current equal to the difference in voltage divided by the resistance of the cells/wire connections. As the resistance is very low this could be a large surge! Hope this makes sense. Happy flying!

Only thing I am missing (or haven't found in an other video of you) is: I have an S500 which requires a 3s battery, I want to buy two 4500ah 3s batteries and usually use them in parallel. I assume i need identical charge state (being best for the battery). But can I use them individual as well and then use them in parallel again?

Painless360 Did you know that you should also have done a Parallel & Series wiring so that you get both Double the Voltage & Amps. Remember that you do NOT exceed the voltage of the ESC, else you will fry it. Connecting in parallel gives you more Flight time. Most big scale RC Helis require two 6S1p batteries wired in Series. I prefer to wire them up in both Parallel & Series. I just make sure I don't exceed the ESC Voltage period.

if i understand this right a 3s 2000mAh 10c 12.4 battery contains inside it 3x 1 cells 2000mAh 10c ~4.15v packs (safe recommended charging voltage). So with those LiHV batterys that are now showing up i could take apart a larger pack like a Turnigy Bolt 500mAh 2s 7.4v 65c - 130c to get 2x 500mAh 65c - 130c ~4.35v (can be safely charged to 4.35v per cell) for a single cell rc model and say run in a hubsan quadcopter as a example provided it fits. This would be a massive improvment over the stock batterys of most single cell quads right? slightly higher volts with high discharge giving way more power at a cost of weight.

Would it be possible to just buy some 2s packs that are the same brand, mah, and C rating and combine that with the 6 to get 8? Ive asked this in another forum and got mixed answers. Some said NO WAY!! And others said its no different than combining two 4s packs to get 8s. Thank you

can you list all the connectors and wiring you used to create the series connector for the two batteries?

This was a great video. Is there a source of info to find out about individual battery pack configurations? For example, I have a laptop battery HSTNN-YB02, 8 cell, 14.8 volts.....I've taken it apart and it looks like I have two sets of 4 batteries. Each set of 4 has 2 batteries connected in parallel (3.7 V as measured) and the two are connected to another two in series (for a measured reading of 7.4 V). .........I think I understand this...then the set of 4 is connected to the other set of 4 I think in parallel.........so I think this should then give me my two times 7.4 or 14.8 volts total.....but the other set of 4 gives "0" V when I measure and the total V of the 8 is 7.4 V on the board (assuming I'm measuring correctly).............the numbers/letters on individual batteries is HL9FJT5 and then 037953.......If there was a source of information to ID the individual battery voltage from the numbers/letters on it, I could then confirm or refute what I'm thinking.....and information to better understand if I have the correct idea about parallel and series attachment is all about........The reason for all this is I'm been trying to figure out if I have a laptop battery problem or a laptop charging problem. Sorry for the rambling comment.

Clear learning video, but what happens if 2 differend 4S accu's are used, one 4200 mah and one 4000 mah are they middeld 4100 ?

@Painless360 4 года назад

Depends on how you connect them. Please see the updated version of this video - link in description

SO YOU ARE SAYING POSITIVE FLOWS TO THE NEGATIVE, BACK TO THE NEGATIVE ON THE MOTOR?

@Painless360 5 дней назад

See my videos on RC basics if you are confused. Charge doesn't travel around a circuit, electrical current does. Best of luck

Hi Painless, my question might be painful but I've looked through the comments and I can't find the answer.I am an newb when it comes to batteries so I hope you can help.I have a Flamewheel F550 and 2 X 5000mah 3s lipos. I would like to combine them in some way to ech out more flying time. I'm presuming parallel is the the right way to connect them. Is that right?Please forgive me for my lack of knowledge.

@madprism 8 лет назад

I worked it out, thanks for your lipo video as well, really good info. I have way to high c rated batteries 65-130c .

@Painless360 8 лет назад

+Tamati Tapara great! Parallel gives you more flight time..

Thanks for the video mate. I have a 5th scale vehicle coming from china it's the fid Dragon hammer voltz it's brushless, and I need to know what will be some good connectors to solder to the wires . The motor will be running g off of two 4s 16,000mah 25c lipo battery packs. The esc is the ztw 300a beast pro.

Hi, sorry for the silly question (love the channel btw) I have two 11.1 3s 2200 mah batteries I would like to put as parallel as I would like a long flight time. I work it out to be 66amp would I have to get ESC's rated to 70A? Thanks Matt

@Painless360 7 лет назад

In parallel it would be a '11.1v 6S 22.2v pack..

@thmls5744 7 лет назад

Painless360 no Lee that would be in series in parallel you double up the max amp draw and the capacity

@monsta21cb 10 лет назад

ok i have a esc that has a y splitter for series 2x2s to make 4s but i bought some 4s batteries that was on sale how can i make a splitter to run just the 4s when i want to

@Sky.Travel 8 лет назад

I have three 4s 1800mHA 65C batteries, when i connect them in parallel, it's will give 195C will it effect my motor and ESC, I know My ESC and motor can handle 4S.

@Painless360 8 лет назад

+Skytech Today No, you'll get a 65C 5,400mah pack.. ;) My advice - buy the right battery for the job..

@rosinstein1501 5 лет назад

So if I understand correctly parallel will accomplish more range and more operating time @ the voltage of one battery and series will give more volts or more punch or Higher output demands and the mAh of one battery?

@Painless360 5 лет назад

Both provide more useable energy for the model. It's how that's available to the model that changes. The higher voltage will turn the brushless motors faster so you do need to reduce the prop size normally. See the newer video on this topic for more details.. Best of luck!

@superslug2516 4 года назад

Suppose I connect 2 lipos first in series and then in parallel in my rc plane. What changes will i see, not in numbers but in the flight performance

@Painless360 4 года назад

You can't do both with the same two batteries at the same time...

@superslug2516 4 года назад

@@Painless360 No actually I meant in different situations

@Painless360 4 года назад

Without a rework of the ESC motor and prop you won't be able to do series...Happy flying

@AzRavnGrl 9 лет назад

If you kept clips on your cables, could you switch configurations back & forth (parallel to series to parallel) depending on your needs? Assuming one's solar power & inverter --if used-- would be adequate either way, would switching like this cause any damage to anything? Just curious...Thank you.

@daryld1736 4 года назад

can you connect 2 lipo batteries in series. when they have the onboard chip in side the battery case?

@Painless360 4 года назад

I'm only aware of an onboard chip in the BattGO batteries... Shouldn't make any difference.. Best of luck!

@stardoggyxx 4 года назад

Hi, just watched your video and it’s very helpful, I have a question if you could help? I have a cctv test mointor which the battery doesn’t work properly, on the charger it said 12 v in to charge but when I do that the charger get very hot and doesn’t charge properly, when I took battery out it looked like it was 7.4 battery that was in series, do I need use a 7,4 battery charger as original didn’t come with it , also the cctv mointor has a 12 v out and confused how that works?

@Painless360 4 года назад

Tricky to comment without the specifics of the monitor you have but that sounds like there is an issue with the charger, charging circuitry or battery. You usually need a higher voltage from the charger to push the current through the battery you're trying to charge but if its getting hot somethings wrong.. Best of luck

@utsobkumar265 Год назад

which system of this two will help to increase DC motor rpm and torque also....?

@Painless360 Год назад

More voltage equals more RPM. If you want different torque, look at changing the motor... Happy flying

@samuelvb 8 лет назад

can I connect two identical batteries in parallel and use one lipo alarm connected in balancer connector with a Y cable? (one Y cable to power connector and other Y cable to balancer port)

@Painless360 8 лет назад

It would sort of work but not well as you're only monitoring the cells on the battery you're connected to, and while that is useful, won't spot if one of the cells on the other pack is in trouble.. Best of luck!

@a007raptor_3 4 года назад

Can you use a 4000 mah battery and a 5000 mah battery in the same car like a xmaxx or will this destroy something??

@TheZodiac31 8 лет назад

It's a silly question. But can you connect a bunch of sets of series batteries in parallel also to get both higher capacity and voltage? and is there a specific order in which you'd do this? It is really an RC question. And for that I apologize. But I can't find a definitive answer to this question anywhere I've looked. :( Sorry for such a silly question but numbers aren't my thing. lol

@TheZodiac31 8 лет назад

er current..... Not voltage.

@Painless360 8 лет назад

Yes you can, you need to be careful as cells need to matched ideally so they have the same internal resistance, voltage and capacity. It's easier to buy the battery in the size you need now - LIPO prices have fallen dramatically in the past three years..
