LiPo Battery C Rating Explained 

No wonder my battery is puffy, and I've been in the hobby for 3 years, thanks for the awsome video

I've watched ton of videos on youtube....but yours is the cleanest explanation so far...thank you !!!

Thanks so much for this.. got back into hobby few months ago still learning did not want to hurt my arrma outcast !

Best video I’ve seen explaining c rating!!! Super informative!!! Thank you 🙏🏻

This came in handy while researching batteries for Airsoft. Thank you.

wow, this is the best info i have gotten on the C-Rating... i'm getting a higher C-rating...been trying to find the right combo .. i already have a 30C ESC and a 1534Kv 2-3s Li-Po electric motor for a foam training plane with a 48" wingspan (i know that's a lot smaller than a lot of Horizon Hobby trainers but it's hard to scratch-build a 51" or 58" wingspan guys, IMO). thanks for the great, great video. I will click your link for the combo suggestions.

Is higher c rating heavier or anything negative about going over board?

thank you for this ! been kinda worried when looking for batteries so this helped !!

Are you sure? Because I got a battery GNB HV 120/240 C and seems like it damaged my ESC (speedybee F405 55A). One of the 4 ESCs of the 4 in 1 ESC sometimes work and sometimes don't after I used this battery. I saw a video from JB saying the opposite. Thanks in advance for your return.

I love your explanation, so spot on! Good job! Just one question, does higher C rating means it discharge the battery faster with a lower C rating?

Best explanation. Thanks for the rundown for dummies👍

💥 BOOM LOVED IT ! Simple and to the point thanks

Thanks that’s the answer to my issues, as my motor was cutting out, and I thought it was because I ran a 75c through a 30A esc

Well said. Completely understand now.2 thumbs up.

Great video. You explained it well! But I still have a question(what else is new). How does one determine c rating? It it determined by how thick the connections are between the cells? Or is it how thick the lithium metal inside is?

Hey I love ur videos! I have a 2300kv motor and a 40 amp ESC. The battery I wish to purchase is 1000mAH and has a C rating of 20. The voltage is 11.4V. I have calculated the continuous discharge is 20A. Will this work with the 40 amp ESC?

Perfect info.

Thanks. Does this mean lower c rating gives longer flight time! I am confused because I got 4S 120c packs which give me less flight time thinking of dumping the batteries, so why higher Cs are more expensive ? ! I just ordered 100c. Should I order 20c better! I am flying a T28 FMS Trojan 1400mm aircraft. Is this also applicable in rc cars ?! Looking for high speed and longer flight time. Thanks

I've been using 75c lipos for my 3 and 4 inch quads. I accidentally bought two 850mah 45c batteries. I assume the 45c batteries are good for cruising but not for freestyle flying where I have a lot of full throttle blips?

Does putting them in series doubles the C rating? Or does the C rating stays the same. Say two 2s lipo with 50c makes a 4s 100c when connected in series?

finally got an answer to my puffy batteries - great vid

I'm running ads on my x max and my xrt and those LiPO batteries are Traxxas batteries that are only 25 C why do you think they go so low on their sea rating I'm just wondering because x-maxx and xrt run hard I never noticed the battery pack get warm or puffy yet I'm charging an 8000 me 130 C 15.2 volt lipo in my Redcat I have the amps set at 13.4 amp charge rate do you think that is okay for charging?

I have one battery of mini RC Heli of 1S 3.7v And 300mAh and I bought new battery 3.7v And 500mAh thinking it will give me more fly Time but it just wont work. It stops immediately I think it has something to do with these C rating. Can I change C rating by manipulating circuit on battery?

I have a castle creations Mamba Monster motor and esc in my RC8 with a Venum 4S 5300 70C battery that performed great. It recently died. I bought a Zeee 4S 6300 80C. Is this suitable or should I go higher on the C rating ?

Question, I have an EDF 5075 kv650 with a hobbywing 160A ESC. It’s rated for 50volts. I used 4x 11.1 3500mah 60C Lipo Batteries in series. And they heat up fast, 1 of them even puffed up. I won’t be able to fly the jet in that state. Will this problem be solved if I go for a bigger C-rating?

I just bought a 2s lipo with 100c. I shouldn’t have to worry about it puffing up now right?

I will need a battery pack that can take a continuous draw of 20.83 amps. I need to know if each battery in the pack has to meet that rate or if that rate is increased by wiring in series.

Really helpful video.i have a question too.the esc i'm going to buy is 60a and it says maximum 3A.How to calculate the power to buy a lipo with correct power?

Thanks for the info, you've explained it pretty well. I've been considering getting back into rc trucks, but electric this time instead of nitro and I hop in seeing lipo this lipo that, when I was in the hobby last nimh was the thing to use and lipo was for the rich folk with nothing better to do lol. So I never learned about it. I know a bit about li-ion batteries but not lipo and this c rating I kept seeing with the brushless setups along with conflicting info saying I need this much but not that much blah blah. I think I know what I need to look for now for the motor set up I plan on running now that most of my confusion is gone.Thanks 😊

Done subcribe bro.. bro, i have question.. quad fpv can use the 20C rate??

so my rc car has a warning saying that it can only run batteries less than or equal to 25c, why is that warning there, can i run a higher C rating battery even though the car warns me against it?

Best explanation by far

Tony I got a question for you I want to run a dual two 3s 5000mah lipos instead of a single 5000 pack for scale 600 size helicopter the weight is about the same, with two lipos I can put the on each side and slide them for CG adjustment?

Can I use a 2s lipo 80c for Traxxas slash 4x4 without damaging anything. Been using 2s lipo 65c for my truck.

So my stock car came with 25c rating if I use a 30c rating it could in crease my performance, if it can handle more? Than 25 c?

When using a dual connector for such as the arrma kraton, needing to batteries instead of one to the esc, can the discharge rate or c rate be different between both batteries/packs?

What if i need tham in serial and thay have not the same c rating like one is 50 c and second is 80 c it is for small quad but here shouldn't be diference with plane or car

Great explanation!

Hi I’m in the beginning process of building an electric surfboard but I don’t want an ESC unless I really need it , can I run my battery straight to an ON OFF switch ? Cheers 🍺

So I still don't know what it means, just that I should use at least 35C or larger, but watching this video I still don't know what C is. Is there a unit of C? How do we apply it?

Great video, to the point. Thanks bro!

Thanks, very informative. This helps out a lot! 👍

I have a question, I am looking to buy new lipos for my brushed 1/16 e revo. Is there any difference or drawbacks to going with 35C from my previous 25C? Exact same battery. Also, i am buying new ones because the old ones are bloated, but i think thats just because i improperly stored them for a long time.

The stock batt in my heli is 300mAh 30C and it always comes down hot, about 120F. I tried a 350mAh 50C. Same thing. You want to take a guess what the problem might be?

Sir one cell samsung original i take nd c rate is 2A then our fast charger is 9V 2A so how its use nd plzz explain how it work adapator nd battery

Hi there I have a 2s 980mah 30 c.lipo What amp charge rates the best to charge thanks

Saw a video on taking the c rating and times it by the mah gets you the amps mine was 15c x 1.5mah = 22.5amps my battery is 1500mah \ 15c .... Not enough play time trying to figure out if it my esc/motor will be ok if i buy a 4000mah \ 30c battery?

Thanks for taking time and sharing all these helpfull tips, this is the best educational video. Tons of videos up in here, most of them are conplete BS and collecting view counts with headlines. But I still have one more question, how can person choose proper C rating battery for a given DC motor ? Thanks

Best explanation 🍺

Thanks for the info, subscribed to your channel !!

based on the weight of your rc being runned on a single battery pack.. higher c rating means higher torque potential, higher brake power potential and higher acceleration potential. higher c rating wont affect maximum speed. Also too much acceleration is funny first, but it destroy your transmission and differentials...it is better to lower acceleration input by 50% on 2wd cars and 20% on 4wd cars. This way you stay in control and your car doesn't always do whellies. Also your differential will last longer. If you decide to lower your gear ratio to have higher maxium speed. it is very important that acceleration input be reduce otherwise you cause big stress on the motor. This is where higher c rated battries offset can be used to gain back the lost acceleration. instead of putting all the stress to your motor, your battery is going to get stressed so your motor doesn'T over do it. when doing those setups remember to apply auto brakes around 20% and brake power at maximum 50% This way your motor will remain warm and you will not deplete your battery too quickly. There is a reason why huge tires are made for higher gear ratios... not for low ratios.. the transmission and the differentials. when 4 small wheels turn very fast it is easy to make them stop or turn the other way around. Bigger wheels tend to disbalance if you turn to fast and braking them to fast will send all that energy/mass stright to your drive shaft and differentials.. anything can be done on rc cars.. and every rc cars can be lightning fast... but then there is physics..

Ok thanks. At least I get the basic idea and not confusion.

Okay so my 5000mh with 20c gives me 100amp discharge and that is exactly how much I need, what about if my battery is half full, will It be safe for a battery to pull 100amps ?

Can we calculate the c rating of a lithium Ion battery?

Can i pair a 35c and a 50c lipo? both have 5000mah

I got a question sir if i may, will a 2200 mah 20c battery give me the same punch in a multiroter as 1800 mah 25c?

Tony, Thanks this is Good info, I need to get back over to the forum..Its been a while.. James

I suggest Everyone to buy zop power batterys, they Are soo Dubable and dirt cheap! I got like 10 of them, 4 2s, 2 3s and 4 4s (between 60 and 120c

Thank you ! Very helpful.

Thank you , it was very clarifying.

If your C rating is to low can it hurt your battery? Thanks!

Thank you so much love you man

can i ask you something how much " c " is there in a 1200mAh 7.4v LiPo battery?

What happens if you mix c ratings if building a bigger battery ?

thanks tony this helped allot keep it up

Great help👍

The Sonicwake V2 36, recamends 50c ratings ,my batteries are 80 C ,horizon Hobbies ,say I can go bigger,new to the hobby.🇨🇦80 c is better than 50c correct thanks

Thanks

Sooooo higher C rating means less flight time??

`- What then, if this "myth" actually originates from using too much charging current, and things have turned the wrong way? - Does the C rating give the user any information about the battery's maximum allowed charging current? - If not, how can the maximum allowed charging current be found out? - And finally: What happens if I charge the battery with too much current?

Is it okay if may esc is 125a and my lipo rating is 110c ? Thankyou

What battery do you recommend?

Thank you, i now understand!!!

Thanks hey tony where you been no videos in a little while?

It doesn't help that some batteries fudge their C ratings. My power hobby 50C/100C gets way hotter than my 25C/50C Traxxas

I just fried my ESC 2s 5200 100c had two batterys in series making a 4s

Wonderful , thank you!

Is c affect the duration of playtime?

Does the same go for Airsoft ?

Thank u so much for sharing 👍👍👍👍🙂

So higher c rating means battery will drain faster?

Any time you say go bigger in a youtube video you get an automatic like

can higher c rating than recommended damage my rc vehicle?

NICEEE

Don't know or understand why anyone would want a 30C battery? I don't own any batteries less than 50C rated.

My battery is a 3000 mah 30C, so 30×3000/1000= 90amps max discharge rate, my motor pulls 20A peak+ few amps for receiver and servos, I should be chilling in here ahaha

What about airsoft guns would it be the same

Its also how fact tou can charge it

If the "C" rating was explained , how come I am none the wiser ? Because it wasn't.

I have a 2s 220c

You know your batteries

And voltage

Ohhhhh that why my cheap ass battery is so easily Puffy.

Does he even explain what the C stands for??

Go out and get the highest C rated battery that you can find... Don't get more than 35...😏

You didn’t at all explain the c number. You simply said the higher the better. Stop making videos that waste people’s time

LOL! First comment!

What's the meaning of to charge at 1c to 3c please explain in simple terms thanks.

All of these BS videos on the internet. Glad this one helped me.
