I know this is an older video but C rating does matter.
A higher C rated battery will be able to sustain higher voltages but also at higher current output. This will allow an RC car to accelerate out of a corner more aggressively, or for an RC boat to get out of the hole faster. For these reasons, it is a great idea to select a pack with the highest C ratings that you can.
Keep in mind the stock system was designed to run off of low c batteries. A noticable different would be more likely in a castle system with more power hungry components
@Ezra Redgwell But didn't he just get this X-Maxx though?
Yup. My Outcast 8s and EXB K8S running the XLX2 have WAY MORE punch and top speed with the gens Ace Bashing Pro 100C batteries than the cheaper options indeed. Furthermore, the gens ace batteries will outlast the cheaper options long term.
Newb here. If my understanding is correct, the c rating is the amount of amps the cells can continuously discharge. Amps are drawn from a circuit, so if the electronic circuit in the car only draws 40 amps then a cell capable of more isnt going to offer any performance increase other than the cells ability to maintain that lower amp draw easier, meaning less stress on the cell, but at the same time that higher rated cell can reach that 40 amp rating of the circuit while suffering less voltage drop which will give u a little more punch off the line but ultimately shouldn't make any difference to over all power output.
Yup you u got it. Pretty smart for a newb LoL.
Absolutely
YOU are 100%CORRECT!😂👏👏👏👍👍👍👍👍👍👍
No. C rating is multiplier of how much faster a battery is capable of discharging. 1C 1Ah = 1A for one hour. 10c 1Ah= 10 Amps in 6 minutes. 100C 1Ah = 100A in 36 seconds. Note that discharge capacity changes based on SOC.
Interesting outcome , thanks for showing us 👍👌👍
The higher C rating seemed to increase torque and acceleration. The gens ace batteries seemed to be way more energetic. Not to mention they did backflips which proves the tires are in fact spinning up faster and harder than the Turnigy batteries. They might top out at the same speed due to some other bottleneck in the system but those extra amps are definitely helping with the initial acceleration and torque
Very cool compare video and a great way to start the day. Seeing the xmaxx flop around before work. Good day woot woo
This couldn't have come at a better time!! Me and my dad were debating over what "C" rating to get, and this video saved me 40 bucks!
Thank you so much!
(XMAXX hitting the sand is AWESOME!!)
don't worry about c rating unless you plan to be very competitive. most systems will never use more then 10-20c at any given time.
Ok. Thx man!
I would like you to see you do this test with 2 xmaxx Really appreciate the video thank you keep up the amazing work
Love when you test stuff
Thanks for clearing this up for me.
Should do a blind “taste” test like they use to do with Coke and Pepsi! Now that would be interesting. Have someone else put the batteries and do a timed bash run with similar manoeuvres. Awesome videos by the way.
Great content as always
Great video brother! I need an XMAXX. 💯
Hey there! I noticed I cannot turn my punch up all the way with my max 6 or max 5 with a battery with a low c rating.
Your hitting sand banks with your xmaxx and I'm still hitting loader banks of snow with mine lol hopefully it warms up to -20 degrees Celsius soon,we've been having a cold snap and my hunting trigger finger is itching to hit trigger for rc hahah great video my friend
🤣🤣🤣🤣. The struggle
For sure buddy I couldn’t leave till my truck was tore up lol
Great video👍🏾
Stock esc vs castle mx8s. Easy to put back to stock since it does not need a mount and can show how well the stock motor can do. I run this setup in one of my Xmaxx
Good video, it's a question many ask. 👍
I was wondering about this. I got the big rock it recommends. 11.1 50 c at least.I have a battery thats 11.1. 35 c ..so i may be able to use this battery correct?
Gens ace batteries seemed to have more burst power..going from a dead stop with more force..
Just curious, since I didn’t know what vitavon was until I started watching your videos, how long does their shipping usually take?? I ordered every single part they make for the XMaxx. Hopefully it gets here soon cuz I’ll have the new castle system in it this week.
Thanks for the videos and fueling my RC addiction lol.
Ebay can take a few weeks.
Nice video, where'd you get the mini speedometer? Again nice video. I have a traxxas emaxx, outdated sure I know but I love it! Wheels 👆!
Good video thank you
Low c rating batteries will cause bigger ripple voltage and damage your esc. Pulling too much current will also damage a low c battery.
BINGO 💯☝️
Ripple voltage? What kind of electrics is that? lol it’s a dc cell don’t know how dc cells generate so called ripple voltage. Damage comes from heat and low c high draw generates more heat vs high c bec of batt resistance values.
Done this a week ago with, ZOP 45c GENS ACE 50c and the stock JLB 30c running in a Typhon V3 blx. Great test to see this mammoth perform
What were your results? Similar?
@@billyhighfill top speed pretty much the same had a little head wind. But the punch on the Gens Ace 50c was very noticeable. From 30c crap battery, 45c Zop (over rated) to 50c Gens Ace mega attitude on take off.
Nice video man
I believe the 100c has better response time at a lower rpm to mid range rpm. That's why they are able to get the XMAXX to do a backflip compared to the 20-40c
yeah exactly, more punch is term
My traxxas lipo is 5000Mah is 25-50c, 50c burst.
nah. i bet its just the weight difference
I also saw more tyre ballooning and diffing out with the Gens Ace. Not convinced the larger current lipo is worth the extra cost.
Man oh man. That's a rough question. It should! But not only do companies inflate these numbers but your motor or electronics need to know how much they can draw. I've always wondered on Traxxas stuff if the reason they're so ambiguous about this is because their smart systems don't allow full bursts. Especially when it's not their brand. But 20 constant current vs 100 should for all intents and purposes. Especially important for flying vehicles.
Does any company actually have proven testing, on any of the high c rated Lipos they sell? And what do these tests indicate, as far as performance?
Wouldn’t it be more acceleration potential and less battery heat from consistent bashing.
Hi,
In a special project we need total ~2000Wh lipo pack. It can be in 6s configuration but not limited to. The main requirement of the project is that the battery pack should provide 40C (or above) current output by 30 seconds without any issue.
For example, if we use 6s 5000mah lipo, it should give 200A continuous until the end of 30 seconds.
Could you please offer your suitable products for the given requirement?
Best Regards.
Video after video !! 🤣 Why don't you take a break n get some lunch ! Cuz I need to ! Great work !
😂😂 man I have 5 in stock and 3 more in the editor. LoL. Got two possibly 3 more to do tonight. I usually take a day or two off a week.
Are u running 6s or 8s in this? Figured it was 8s but wanted to confirm? Also, u should do this test with the upgraded xmaxx, bet u will notice a way bigger difference. The stock system doesn’t pull near enough power to truly get a good result imo. Either way, Good vid. Keep up the good work sir 😁👍
Very good buggy 😄
Interesting comparison. I recently got wound up about the Internal Resistance of different batteries. Is this something that you keep track of, and if so how ?
I don’t keep track of it on any of them but I do have the Esr meter and the higher the temps the lower the IR and the more available amps.
@@ExocagedRC in a "better" lipo charger there is a IR resistance feature, once the resistance get into the double digits, the battery is a bit weaker... if one cell is significantly higher, be aware the that cell capacity is quit a bit lower than the rest, so when your charger says the lipo is "full" that cell contains less power. so it will deplete a lot faster than the rest, so i recommend not running a lipo with a weak cell down as low as you use to.... (try running it close to what you normally do and put your hands on it, it will feel significantly hotter than the other cells)
# basic rules to keep your IR good
Always put your lipos in storage mode when not in use (3,6-3,8v pr. cell)
Dont charge your lipos the day before use... the lipos degrade relatively quick when keept at full charge
Don't over deplete your batteries past 3,6V (you can drive it to 3,5 because it will bounce back 0,1ish but always aim for storage voltage as your cut off) and do your high amp draw stunts during the first half of your ride... when your battery struggles, more throttle is not the answer ;-)
Bro how the fuck did you comment a week ago.
The higher c rating seemed to have more punch they did do a back flip the lower c rating ones didnt have enough punch from what I saw, on the speed run seemed to get up to top speed quicker with the higher c rating. Guess need to do a 0-45mph speed times
Why do the the lower c-rating packs have 2 numbers [20-40c]?
The lower number is the continuous discharge rate that the battery is rated for. The higher number is the burst discharge rate for short periods of time.
I have some hrb 50 c I use in 1/7 trucks no issues put them in a sonicwake boat and they cut out .?
Ooohhh the sonic wake is an amp hog, that boat pulls so many amps it can pull most any battery down into lvc early.
They ship fast from addison il. I was very pleased with his customer service. My lhs wants 60 to 70 for same type of battery. No way. These batteries make my plane fly very fast . My traxxas 4 tec 2.0 brushless do 50 mph.
Where did you get those t90 Traxxas connectors from?
Normal traxxas plugs
What gps are u using
Are both brands of battery of the same Dimension and same weight but all in all another good run video you produce really good content I'm excited to see the new super light come out
They're going to be close enough in weight to where it doesn't make a difference. The x-max and weighs 20 lb so 100 g or so one way or the other is pretty inconsequential.
It is during a backflip
@@andyvannort2743 and I bet temperature on electronic with a hundred c a lot cooler than the other one
@@extremercbashers9975 yup cooler electronics, hotter wires. Cant wait to see this test on an xlx2 so we can see the difference when the motors actually pulling some real current
What are them adapters male traxxas to female ?
Nice test, I was expecting much more from that 100c rating. They really seemed almost indistinguishable. In a blind test I'm not sure if I could guess which set was which.
Thats because they're not truly 100c. They're probably a lot closer to 20-25c. Manufacturers pump up the numbers to get more money and sell more batteries.
@@rc-daily orrrrr its because both batteries are capable of putting out more than the required power by the esc, even if the 100c was actually 100c which i believe it is.
@@rc-daily 100%FACTS!💥👍
@dirtrider88 if they could put out 100c it would have melted the wires in half....
You should try the same thing but in a car that has an ESC with Castelog, so we can see those amperage.
An excellent suggestion. Battery temps would also be of interest. Some extended climbs might be informative, as well.
I notice a difference in "punch" with a higher C rating but not "top-end".
The biggest difference...and it'd be nice to see if anyone else has seen this...is false low-charge with 20C while driving in really cold weather....swapped out to a 35C on up and didn't have that problem. Notice this several times at Pro-Line By The Fire years ago.
In cold temps yeah all batteries loose c discharge mah and will puff easier due to all that. I’ve done esr tests with the same battery at different temps and it shows up well like that.
Leapod power 100c in my kyosho mad van vs fantom 120c. The fantom makes it do wheelies alot more.
Pertfect video, was looking for this info! You just saved me 300$ my buddy! What about the heat?
Didn’t notice much of a heat difference. Larger MAH makes more of a difference from what I’ve personally seen
Man I miss my E-Maxx so much, what a damn beast. I just hated how literally every time I took it out something broke.
See which one has the longer run times
Man that place looks familiar, are you in Florida?
Yeah Middleburg
I bet it is difficult for you to run a box stock Xmaxx huh? I know I would have a hard time after running Max5/1100kv w/ 1.5 gears in mine. I'm sure you might break less though. LOL
What’s the weight difference in the batteries? Maybe more of a difference if they were the same weight?
The 6000’s weigh a little more
But not enough to change anything on the Xmaxx
Can i put 100 C in a brushed, i think it will be fine
Good vidéo 👍
The C rating indicates the punch, more than top speed
Agree , should be doing drag times or lap times
Higher c rating is also less demanding on the esc because it can get the power its demanding from the batteries easier 👍
Actually it doesn't indicate that, The C rating for a LiPo battery, quite simply, refers to the capacity of energy the battery can safely discharge, represented as a multiple of its overall capacity. A battery that has a higher C rating delivers more energy, and that means higher performance. But not more power.
Yeah I look at it as the voltage is the horsepower and c rating as the torque capabilities then dependant on you’re system and gearing is how much it can utilise by work load.
@@ronbrannen887 deep cell vs crank amps. ?
Nice video 👍 The C rating should help keep the heat down in your cables a little bit too.
What do you mean?
@@DoRC Higher C rating should allow the voltage to flow from the battery easier since it has a higher "discharge" rating. That means less heat. Of course all battery manufacturers inflate their discharge ratings so it's hard to really know 👍
@@GreatLakesRC it's actually backwards from what would be true. The more current that can flow from the battery the more current that will flow through the wires. This means that for any given resistance in the wire they will get hotter. To put it simply the more current you put through a wire the more of that current gets dissipated as heat in the wire.
@@DoRC Just sharing my experience in my Kraton 8s. My power hobby 100C lipos ran cooler than my Zeee 80C. Same gearing.
@@GreatLakesRC Yes the lipos themselves will run cooler if they are able to discharge more current. But not the wiring.
I fly 3d 6s planes and have had 2 ESC fires through old saggy high C rated lipos ... Cure to use a Capacitor pack close to ESC they act like dampers for the ripple voltage and keep the ESC to lipo wires as short as possible.😉
You are the king of bashing. Enjoy your videos.
I need an xmax i run slash 4x4 vxl got mine up to 64 mph with stock everythin 19t pinion 54 t spur 5200 mah 80c 3s zeee batteries it screams fun but they dont hop like max or wheelie like max
With an upgraded power system Demanding more amps the higher C rating would be important.
The C rating is the "drain /discharge" rate... Higher the C rating the higher drain... Generally the higher C rated Lithium batteries have a "Lower Internal resistance" which means they can deliver more Amps & empty faster when required.
For arguments sake If your using an upgraded electronics system pulling say 300amps & you are using say 25C rated Lipos, they would not be able to deliver the Amps required as they are a lower, slower drain cell with higher internal resistance.
This will effect your performance & aswell as not getting the full potential out of your setup, this will Create lot of heat & put tremendous Strain on Lithium cells.
This is Where a high/fast drain, Lipo with Low internal resistance shines & will deliver the Amps required fast to get full potential out of your system & battery should keep cool under pressure.
Thanks for Sharing fella.
Great playground you have there for the Xmaxx. 👍
I mean from what I saw, the gens ace definitely have more torque.
I didn’t see much but it felt a little better.
For me anything above 40c is good well as long as it's 6k mah or higher
Damn bro take care of them bearings 💀 but good video
Flying, the higher the c rating, the better pull out power we have for when we do stupid crap, get into trouble, we can regain control faster. BUT, with today's flight batteries, a smart 30c pack is better than most manufacturers' 50c packs.
WE actually run more smart packs, 30c, for flight times & size to put in really tight fitting places. (With the smart chargers, the c ratings get better with repetitive use.)
My 2 cents. 😁
So you’re saying the batteries you use actually have a break in period?
I'll take whichever one has less chance of setting my house on fire. Please make that the next test!!
In all seriousness, fantastic review on a topic I was very curious about! On a serious note, reviewing packs safety differences would be fascinating topic as well.
What servo do you run in your upgraded xmaxx man
Stock. I haven’t had a need to change it out. The stock servo pulls about 460oz on the tester so it’s strong, just not very fast.
Would be a epic test if all 4 of the lipos are brand new in the box
1 set could have had 4 runs on them & the other set could have had 40 runs on them
These are pretty close to equal in runs. Maybe 6/4 but close. Neither have over 10 runs.
Difference is in the rated amp draw, higher C batteries won't have the risk of overdrawing causing damage and will not get as hot per similar amp load vs a lower C rating battery ...
Higher C ratings are fake, the higher MAH makes a big difference
Got to be a marketing money thing on this c rating
As far as I know, c rating helps when you are racing distance over grass, or in mud. That is at least how I noticed they struggle. I have had many premature brown outs from hitting the batteries too hard for to much time.
Yeah batteries will dip under load.
Think of c rating like a garden hose nozzle. The bigger the number the more open the nozzle is letting electrons move more efficiently.
But be aware a higher c rated battery matched with an ESC that cannot handle the load will start a fire.
Or a motor that pulls everything the esc can get from the battery can cause a fire. You don’t push amps. Now if the motor needs 100a and the battery has 200a available the motor can easily get 100a and that’s all it will take however if the esc is only good for 50a. Smoky things can happen.
@@ExocagedRC exactly. Always match your components to work with each other as efficiently as possible.
The C rating is just how much can be pulled from the batter.
Many RC trucks or cars see a performance increase when upping the C rating. This is only because the lower rating wasn’t enough to max out the engine.
Example. Going from a 20C to a 50C and you see more pickup and top speed. But you then go from a 50C to a 1,000C and there is no difference.
This is because the engine can only draw to a maximum. The 20C was to small.
The only difference you will find from a 50C to 1000C is the battery won’t heat up and will last longer (larger reserve)
What is the truck ??
Xmaxx
👍
C rating; C rating will tell you how much amperage your battery can supply. However the amount of amperage draw can vary greatly. A Traxxas Slash brushed 2wd will not draw anywhere near what your Xmaxx will. So a 100C may have 600 amps available (100 x 6000mah = 600amps) but only your Xmaxx will need it. The Slash will only need a fraction of that. So what do we need all the amperage for? The better the amperage the less voltage drop. So at anything less than 600 amp draw voltage (speed) will not suffer as much as the 100amp battery (20x5000mah = 100 amps)
It’s not how fast it went, it’s how fast it got to that speed.
Voltage is speed (horsepower), Amperage is acceleration (torque).
don't believe the c ratings on the label. NONE are over about 30C as tested on my meter that tests the maximum safe discharge rate.
isnt 5000 mAh at 20c 250 amps of discharge current? you have a 150 amp esc, its never gonna matter what c rating the battery has
It's safer to run a higher C rating battery because you're not constantly running at the battery's maximum draw rate. Just because you have 100C available, doesn't mean you're going to draw 100C. But, if your ESC/Motor can draw 30C, and your battery is only capable of 20C, it could spell disaster for the battery. Performance boost or not, I'd go higher with more headroom.
Any chance we can get a comparison if you throw them in one of your big block 800 or 1100kv set up, I bet this is where you’ll see the difference, great content!
The stock esc probably can’t even pull more than 200 amps so the batteries are gonna look exactly the same
Yeah reading all these comments I’m going to try again with the Kraton 8s with 800kv and the XLX2 so I will be able to get some datalogs too.
without watching video i doubt there will be much difference. replace the 100c with graphene batters and you'll find a difference
I've found capacity is king for amps. more mah, more amps. because c x mah = amps.
high IR of an older or poor battery makes a lower amp output significantly.
and graphene batteries are by far the best I've ever used.
higher amp draw loads will show a larger difference between them Aswell
6:10 kids at playfields are such a problem...like they own the place. 🤪
😂😂
He could repeat this test now in the upgraded xmaxx and compare the videos. I think we would see the difference because the new ESC drain more from the batteries, so the difference in performance would be visible
Now we both know that 100c battery isnt really 100c. I'd like to see you compare both batteries on your meter.
They should be the same. The power is the power from the motor regardless of the coulombs. The C (coulombs) rating just defines the rate of discharge from the battery.
The c like what you said is what the battery can deliver. If the batteries can deliver 50 amps and 75 amps but the motor needs 30 amps it’s going to run pretty much the same. I do however feel the battery that has 75 amps of potential energy would give that 30amps the motor needs a lot easier.
Try it with a different esc than trx one, I’m sure there will be more noticeable difference.
Biggest difference I saw with C rating was in my 3s truck, at 25 it couldn’t spin tires, slowed down massively in gras or when going uphill but at 70C I could do standing backflips.
I feel like stock xmax isn’t geared high and the motor doesn’t pull much amps to notice a difference.
That 25c shoulda spun those tires just fine.
I saw more punch with the higher C rating but still pretty equal.
It felt better but in some cases you spend big money on something so no matter what, it’s better in your mind. Seeing it play out on video is a bit different.
@@ExocagedRC have you tried the Goldbat batteries on Amazon? I’ve been impressed with them on how they are constructed in terms of the case and the balance plugs
5000mah x 20c =100amp
6000mah x 100c = 600amp max discharge rate,
in my opinion it is important to have more amp discharge rate in the battery than the esc will give max
True but I didn’t really see that here on this truck. Maybe the stock Xmaxx doesn’t pull so many amps? I may try this again with an XLX2 powered Kraton. Just to see if I there is anything noticeable there
@@ExocagedRC ok if you think so🙄
So completely off topic 🤣 have you seen the new proline Black Mambas? Ryft 🤔
Yes sir I have and I will have a set.
It's very clear form looking at this truck that A it was well engineered to run in it's expected power band, you'll need to gear it to see any difference in top speeds the extra amperage of the better packs can produce, and B the launch is faster on the higher C cells because it gets to it's top speed MUCH quicker, it's very likely that the speed divas have over geared their vehicles to the moon and the amperage sag is the difference they're seeing in the top end.
The conclusion here is a properly engineered platform is running at the speed it's supposed to anyway within the amperage draw it is specified to pull.
very well put
The only place where you will notice a difference, would be on a continuous discharge, for instance a race on a large track where you where on the power continuously over a long period...
We use the same batteries for high powered electric offroad skateboards... (think of it as rc cars you stand on!!!!) there the difference is noticeable when we for instance go up a long hill at high speed, the the lower C rating battery will sag, (and often inflate and die) also over longer higer throttle rides on the harder mountainboard trails, we quite easily kill the low C batteries
Maby have a look at my youtube channel to see what i'm talking about.. (it's mostly in danish, but the fun part is "international")
Great info on that. I’d guess boats and planes would be similar since their loads are pretty constant.
This test is surely flawed as those turnigy 4s 5000 20-40s are the fricken BEST!!!! Man I WISH I could get more!
И какие выводы?
Buy from value hobby 4000 mah nano tec light weight 3 s . 28$ I think its 35 c. I use in my rc planes and cars. Plenty of run time and punch.
I’ve had a few of the nanotech brands and they puffed quick. This was years ago and I may have been using them in the wrong truck not knowing what I know now so coulda been my fault on that
It has nothing to do with speed it’s at the bottom end. Link of the mah as a huge fuel tank and the c rating is the size of the straw
Difference is anyone that says they're battery is 100c is lying. 600A. Don't think so.
^This
Can u explain? Lol
Omega ballpark
Invalid test. You need to compare the same brand (which should mean the same construction if you get the same line of the batteries) and the same size. The 6000 can discharge at t higher amperage than a 5000 at the same C rating.
I'm not saying certain batteries are not better than others they are people need to check out RC groups. They have actually tested batteries to see what their true says and it was an SMC battery that had a true C rating of around 35C that was the highest rated see of any battery they had ever tested. Here's the problem there is no standard that these battery companies have to use to actually come up with whatever their see rating is, they can basically throw whatever the hell they want on a label. It's simple if your batteries are not getting hot while you are running them, they are providing plenty of power, if they are getting hot you do not need to use those batteries in that system they cannot handle the current draw. Also I don't know about the X Max system, but there was a guy who actually tested the mamba 2200 system on 6S and the most it ever pulled was I think around 160 A worth of power draw so these battery packs claim in five and 600 A is not needed anyway and probably no work in the battery do it anywayT
Higher C ratings = FASTER draw of power = more punch top speed has nothing to do with it though. You will achieve just faster and makes you think it's faster because of that.
Any given r/c vehicle has an optimal set-up. The manufacturer can tell you exactly what that is. If the factory recommends a c rating then it is good advice to use that rating as a minimum for that r/c. Going lower may hurt your battery and possibly the esc and motor. Using a higher c rated battery won't hurt any.of the components and the likelihood of any performance gains is negligible.
