I'm back and with another great video. In this video, I will show you how to match your Brushless Motor, with your ESC, and with your Battery. The equasions are simple, and it will save you a lot of headache in the future. If you have any questions about any of this, come on over and post up on our forum. We are always there to help you.
To figure out your amp rating on your motor with only the watts, you simply divide motor watts by battery volts. To figure out your watts if all you have is amps, you multiply motor amps by battery volts.
To figure out the amp rating on a battery, you multiply the MAH by the C rating, then divide that number by 1000. this will give you the amp rating for constant draw out of your battery. If your motor amp rating is close to your battery amp rating, then you can over heat the battery. I would put a 10 amp cushion on the battery. Lets say your motor draws 45 amps, you will want a 55 amp rate battery. If your ESC is only 50 amps, then it could get hot as well, and I would suggest a 60 amp.
One question I get asked a lot is, "Can I run a larger battery C rating without hurting anything?". The answer is YES. Your motor will only pull the power it needs. The battery is not forcing the power into the motor, the motor is pulling the power from the battery.
I hope I was able to help some of you out with this. Please let me know if you have any questions about any of this by posting up on our forum!

Confusion. What do you mean by "bigger" battery? Do you mean a higher amperage rating? Do you mean more voltage? Both could be bigger, one would make a difference and the other would not. If you use a battery with "bigger" voltage, you WILL get more power. This is what "they" mean.

@RcHelpDotCom 5 лет назад

In this video, "Bigger" was meaning the C rating, or Amperage rating. Back in 2011 when this video was made, everyone was saying "go with a 'bigger' (more amperage) battery and you will have more power". But, this was back in 2011 and I need to remake this video to be more clear. I made this video to get the point across that a higher C rating will not get you more power, and if it does, it was not a large enough C rating to begin with. James, I appreciate your comment

@victormadison8662 4 года назад

Tony, you are trying to explain how to match these components but then you say "bigger battery". You also say that folks are wrong when they say you get more power when you use a "bigger" battery. You need to define "bigger". Most of the time the average modeler means higher cell count (4S vs 3S) when they say bigger. You WILL get more power if you use a 4S battery than a 3S battery. The 4S battery has a higher voltage which result is more power. So, don't use ambiguous terms like "bigger" say exactly what you mean (higher voltage bigger or physical size bigger or higher mah bigger).

@ericdiannestrickland7511 4 года назад

@@RcHelpDotCom Ummm a higher C rated battery will give you more power, especially if you use a higher esc.. Example.. you motor pulls 55 amps, but you could put a bigger prop on that allows you to pull more amps, but because your batter can only say put out 65 amps, it will put out more up to the burst and then get hot expand and then fail. but.. if you put say a batter that puts out 65C now that same motor will pull the bigger amp draw, but at what expense? maybe more heat in the motor, maybe more heat in the ESC.. basically your video is very good at setting correct esc,batter, and motor specs, but it doesn't protect against bigger draws.. The fact that brushless motors will pull more amps... power based on the battery and ESC, and load but at the cost of motor damage or even burning it up!!.. We in the RC Boating have this problem all the time to go faster.

@Diogo-dt1uf 4 года назад

@@ericdiannestrickland7511 The C of the battery itself doesn't provide any additional power. What produces power is the load on the motor. BUT, if the load is draining more current than your current battery can provide, probably the battery is getting way hot. Switching it with a higer C battery now you can deliver the current your motor is asking for, and thus getting the "additional" power... Remember, is not the C of the battery that is providing any power. Take a setup which drains 10A. Assuming your battery can easily provide 30A with 20C for instance, switch the battery with a 60C one.. power will be the same.

Still informing (after all these years), those like me that didn’t understand this side of the hobby 👍👍 I had to watch it a couple of times and then do the math on my own choices when a light went on!! Thank you for this great video and explanation.

@brokeddog 7 лет назад

Thanks a million man. I am pretty new to this sport/hobby and I started out clueless. Before I spent more money only to crash and burn I invested in a very good sim which I spent an hour a day at least just learning to fly for my first two years and it did help me tremendously but there is nothing like the actual thing. i hear what you're saying about being careful as to what some guys say on the net. you and a few others have taught me more common sense things like all of the major pieces you gotta take into consideration when shopping around. Believe me I felt like a moron for far too many years and have mismatched components and allof the knuckle head things one does without asking questions and doing the research because there is a lot going on under the cowl. thanks I really enjoyed your presentation and even took notes which I will keep and use..take care, Chris

@cryogen1482 2 года назад

Thank you very much for this instruction video. I recently bought a glider but I am using a different battery than what the box instructed me to use and got mixed info regarding how I am to work out if my battery would work with this motor, using your instructions I was able to work out that my battery was more than enough for the motor and that the ESC can handle the battery perfectly fine.

@RcHelpDotCom 2 года назад

Just remember, the motor is what pulls the power, the ESC regulates that power and the battery just supplies the power. As long as the ESC and battery are large enough (high enough amps) to handle the motor, you should be golden! www.Rc-Help.com

@2002baykay 11 лет назад

Brushless motors are given a Kv rating, which is RPM per volt, that lets you determine how fast that motor will rotate with a given voltage supplied to it. A 980Kv motor powered by an 11.1V battery would spin at 980 x 11.1 = 10878 RPM with no load. The current rating specifies the maximum continuous and/or burst current that the motor is able to handle. When selecting a battery and speed control, choose ones with continuous current ratings equal to or greater that that of the motor.

@windsurfingphd 3 месяца назад

Good video, covering the motor and prop selection. However, I wish you would have provided references how you came up with these formulas for prop diameter, pitch and rpm. You also didn't indicate the stall and pitch speed (or advance ratio) for a successful flight. Did you, for example, compare your findings with ECalc to see if there are discrepancies?

@alexandrugroza839 4 года назад

Does the Esc amperage need to be bigger or lower than the batterys amps. ? If i have an instalation that require 60A , 60/4 =15A about an 20A Esc will work but the battery amperage need to be bigger or lower than 20A Required per motor ? The battery will need 60000mAh or the mAh multiplyed by C rate need to be 60A?

@tylerrickel551 Год назад

Still prob the best and one of only things I can find on what you would think is one of the most common questions! So really on any engine, you can run any voltage battery as long as the Amperage is enough? Is it that simple

@semtech30 11 лет назад

I have a 960 kv motor, not sure of the amp draw. 2200 lipo....and the 30A ESC gets hot and softens the wires to the point it quit operating. Motor just rattles back and forth on throttle now. ESC is shot....so I'm installing a 40A. According to your suggestions I feel I'm heading in the right direction.

What if you already have a motor and want to put it in a new model, but the motor only states size and KV? Some model companies give the kv to match, but what if the kv is good but the size doesnt match smaller/bigger? Some others give GP/EP options, how do i tell if my EP motor matches the GP size? How do I work out the Watts or Amp of my motor with only KV on it? Ive got two motors I wanna use in new models, a 3226 - 970kv, and a 4250 - 910kv

@dustinpratt7594 4 года назад

So you say going from a 3s to a 4s or (up in battery voltage) wont increase power . But say your motors max draw was 50 amps . 50x11.1 (3s lipo) = 555(watts) . Now if we up the voltage to 14.8v (4s lipo) . so 50(amps) x 14.8(4s lipo) = 740(watts) . Which is more power if im not mistaking .

@RcHelpDotCom 4 года назад

3-4s is not what I was saying in this video. I'm saying going up in C rating (C, not S), if you see an increase in power, then your old battery did not have a high enough C rating and was causing a bottleneck. www.Rc-Help.com

@rafaeltorres2886 3 года назад

Increasing series is better for making more power with less amp draw your motors will last longer but never exceed the manufacturers recommendation for the number of cell in series.

@cruzo2355 3 года назад

Tekst źródłowy In your case 2650 was because you had to add weight issiue. But in case of this Edge plane and your set. With solved weight issue can you spend more time in air? 2650mAh is always more time for fly than 2200 or I'm wrong? I would like to understand this good. thx very good tutorial

Hy, does the ESC Amperage need to be bigger that the motor amp with 20% more, the battery also need to have a bigger value but the ESC how it need to be in comparation with the battery Amperage ? i saw that you have a 60 A esc with 50 A battery, if you put a bigger Amperage battery value , will burn the ESC ?

@Simpog7 2 года назад

Can u pair a 50c 7.4 volt battery to a 30a esc and a a2212 motor

@KefirTView 3 года назад

Very good video, but if you're playing around with prop sizes you best be careful when due to prop size you're pulling more amps than your entire setup can handle and you're on the brink of a burst or electrical fire. Use a "Watt Meter".

@rafaeltorres2886 3 года назад

Good power rating is 150 to 200 watts per pound.

@rafaeltorres2886 3 года назад

3.117 lbs you need a motor that can generate 556 watts about 175 watts per pound then you to find out how much room in the battery compartment for your battery how many series cells can fit that will supply enough watts amps volts after that go to a motor web site like, Tom cat and then start checking the motor sizing chart from the chart it will help you decide which motor will work for you.

@InvidiaRaindrops 11 лет назад

hi, i am running a turnigy areodrive 4250 350kv rating motor with a 60amp turnigy plush esc, the motor draws 55amps, this is for a wheeled project, i am wanting to run it on 2 7.4v lipo, i found one 2s 40-60c 10000mah turnigy nano, trying to think if it will be suitable use. i am thinking of connecting them to make a 14.8v, but i am not sure about the c rating. will the c rating double, (so 80-120c) will it brake my motor or esc.

I hope that I was able to deliver my point .. btw, I like your channel :) :)

@GrotrianSeiler 6 лет назад

To get the amp draw from the motor, you said you need the wattage. How do you figure out the watts of the motor from the kv number?

@RcHelpDotCom 6 лет назад

You can't figure out the watts with the KV. KV on these brushless motors means RPM Per Volt. So if you have a 1000kv motor, 1 volt will equal 1000 RPM, 2 volts, 2000 rpm and so on. The best way to figure out wattage is with a watt meter which are pretty inexpensive now, but the motor manufacturer should give some numbers to start with. This is where I would start. Hope this helps. www.Rc-Help.com

@denismoran670 3 года назад

Thank you for the video. It falls down badly for me when it says 'the motor is 700 watts' - how do you know that? It all makes sense with that knowledge, but not knowing makes it impossible to proceed. Also, I have to set up a power train from scratch, and have no 'manufacturers recommendations', so again, impossible to proceed. Thanks, anyway.

@jimpecha 12 лет назад

Great Video ... I am confused over one thing. you mention how to determine the AMP rating of the motor by dividing the watts by the number of volts (700/14.4) 47 amps. If I use the same scenario and use a 3s battery (700/11.1) 63 amps. Does this mean that I need a larger ESC with a smaller battery? 3s versus a 4s battery? I must be missing something ...

@frez777 3 года назад

I'm right here with ya on this ? lolzzz

@rafaeltorres2886 3 года назад

Your better off going with a 4s pack because 63 amps will reduce your fight time. Yes a small 3s pack only supplies 11.1 volts on 700watt motor need more amps to spin it do to the lower volts. its all a balance for a motor to produce 700 watts.

@superdon1chw 4 года назад

So if you had a 80 amp speed control would it not be a problem on that plane ?

@RcHelpDotCom 4 года назад

Wouldn't be a problem at all. The 80a on an ESC is what it can handle. The motor is what is pulling the power.

@granttoye5852 5 лет назад

ok so Kv is constant velocity. NOT kilovolts (kV) got it. are wattages usually listed when you get a new motor?

@RcHelpDotCom 5 лет назад

KV is RPM Per Volt. Take that KV number and multiply it by the voltage of your battery. And wattages are 'usually' on the spec sheet. If they are not, then you will need to use a watt meter to find out what the number is. www.Rc-Help.com

@elfocker 12 лет назад

Thanks for that info. I calculated my set up on my truck, my 800w 2200kv motor with a 80a esc are a good match. My question is, is it ok to use lipos going way over it's capacity? I want to run 2 5000Mah 40c 2s I know it equals to 400 amps. Is that ok?

@AlexanderHL1919 7 лет назад

Hi, I just got a CR28M KV: 1050. That is 2 contrarotating motors, rated by the manufacturer at 320W or 25A each. Do I need two separate ESCs, rated at 25A each? And a battery that can push 50A?

@scottfirman 7 лет назад

Mostly what I hear is a larger battery will give you more run time,not faster. I have noticed that myself. The C rating would determine speed ,that is what determines how much juice the motor can use from the battery. The larger the C rating,the more power you can get out of the battery,but if you go beyond what the ESC can handle,it wont matter,you will fry the ESC and mabe the motor. I would stay within the recommended sizes and "C ratings, a larger battery may give you more time,but if it is bigger,it will not help performance,throw the CG off and you may have problems fitting it in your fuse.

@georgecrabtree6447 7 лет назад

Currently looking for an esc to go with my motor. The motor is 1770 watts and my batteries are 11.1V 30c 3 cell. This means it's drawing 159 amps? So I need minimum 180Amp esc. But then I do the battery maths and work out that my batteries can only put out 66amps anyway? So I need new batteries as well now? Trouble is I can't seem to find a motor small enough using the maths you've provided. The stock motor in the rc would not have been appropriate in the first place? Please help ?

@curty162 12 лет назад

Based on those calculations my motor would want 63 amps but the esc i was looking to get is just 60. Is that close enough or do you think things will get hot? Its for a boat and the esc is water cooled.

This may be a dumb question, but here goes... Does the amp rating listed on a motor indicate the max amps that the motor should be drawing? Or is it just approximately what the manufacturer thinks you'll get? ie: I have a 670kv motor rated at 40amps on a 4s (14.8V) battery which gives me 45.27 Amps. Am I overworking the motor? ( a 5 cell would bring it right down to 39amps, but I already bought two 4 cells)

Thanks for the reply in such a short notice.

Any recommendations when it comes to LIPO Charger/Discharger units?

i have 1100kv motor and 30A ESC and i bought a "11.1v 5400mah 30C lipo battery" is that okay?

two questions for you. although the larger battery will not give you more performance, it will give a longer flight time correct? also, do you have a video explaining how to see how much power was used after a flight to determine the flight times for that setup? thanks
