What C rating do you guys suggest for the Savage Flux HP XL?

I'd go with a battery that's 5,000mah and 30C or better. The Nano-tech batteries are pretty popular for the Savage Flux.

turnigy, venom, onyx, traxxas, spc, smc, all are good brands. I would suggest at least 5000mah, at least 30-35c( I run 45c in my electric truggy) hard case.

Does running high C rates like 60 & above have any effect or?
Or purely overkill.

Check out this link. It will explain it well enough for you.
https://www.commonsenserc.com/page.php?page=c_ratings_explained.html

X gave you a link that gives you an explanation technically. Watch this, http://www.hobbypartz.com/whdocrameonl.html and I think it will be more explanatory of the real benefits of the higher C rating, which usually makes the price a bit higher. I have had good luck with the Turnigy Nano Tech Batteries, which I believe Woodie mentioned. Price is not always indicative of quality, but a high C rating can be very important. This place is usually very good on prices.http://www.hobbyking.com/hobbyking/store/__378__85__Batteries_Accessories-Turnigy_nano_tech.html

I think we all understand that the higher the C the better.
But are there limitations from the device itself?
Like putting more than 8gb ram in a 32bit OS.
You'll only be using 4 gb out of those 8gb because 32 bit OS cant see more than 4gb.

Basically look at the maximum current draw of the device you are powering. Then pick a battery with sufficient C rating to cover that. Above that is pointless, and in run away power issues (shorts for instance) could actually add to the damage of your electronic devices.

The electronics in an RC today are very good but they aren't personal computers. There is no correlation between computer ram and C values in an RC battery. You are only limited by your wallet. You should have all the information you need from the above answers.

Almost, Greg.

Let me put it this way.

What's the difference in usage between these 2:

5000 mAh 2S 30C

5000 mAh 2S 60C


Literally, while playing, how will it differ between the above 2.

Don't say

'the 60 C will let be discharged at 6 times that pack's capacity'

How does discharging at 3 times or 6 times differ in play?

We all know mAh means more play time & voltage means more power.
C rating is still a mystery to me.
Because there are very high C rated Gens Ace batteries but are more expensive than mid C rated gens ace batteries.

Why pay for anything above 50 C of my particular vehicle doesn't utilize the high C rating.

Thanks

The way I understand the C Rating is the ability of the battery pack to sustain a load at hi draw.... so by reading the info I am to understand that the higher a C rating means the longer it will last there by running longer and having more fun....
I am no expert on LiPo batteries by any means though, I am still using NiMH batteries for my electric toys....

Hedonist 222 ....If you read what X linked you to, and watched the video that I sent you to, you should have some understanding of the C rating. I know I get more power and longer running times on my higher C rated batteries. Period. Is it worth the extra cost? I can afford what I want, so I buy the higher C rated batteries. Hard bashing is hard on batteries also, so the life of the batteries themselves comes in to play here. Will the higher C rated battery last longer? Probably not, if we're talking life of battery. We are only talking cycle of battery. The choice is yours.

Clearly someone didn't pay any attention to my post. It's not complicated, you're just making it that way.

Find out what the maximum current draw of your electronics are and then spec a battery with a C rating to match. As long as you got that covered anything greater gives you no benefit.

I'm not experienced enough to know what my Savage Flux HP current draw is.

Anyone handy with that?

Maximum rating is 120A. It's listed on the website. Not hard to find.

Ok

I have a 6000 99 C battery

That means:
6A x 99c = 594

That's about 5 times the draw yet savage needs. Is it overkill then? Is my c rating overkill?
Or, even though it's much more, the savage utilizes the additional c rating?

If we do the math in reverse, the savage really just needs:
Assuming I want a 5500 mAh battery
120 / 5.5 = 22 C

See reply #5 and #6, and read over. Go play with your car.

Like the video said, get the higher c rating and the battery will not be working as hard as a lower c rated one will, heat is the enemy and if running a higher c rated battery will help keep the battery cooler while running...
that in itself is what you would want......
I have to agree with X and Greg and stop over analyzing this and buy the best rated batteries you can and call it good....

Hi guys.

I'm not over analyzing & one main question that I asked hasn't been answered.
Well, partially.

Do I need the 99C rated batteries?
Or are they overkill?
Jam racing & Greg mention that c rating relieves the battery from stress & the required C rating is based on the current drawn by the motor.

I took the above & put it into math.

Current drawn 120
C rating is a variable
mAh is a variable

A x C = current drawn

Let's assume we want at least a 5,000 capacity battery. Therefore:

5 x C = 120

120 / 5 = C
C = 24

By the above formula, if I use a 5,000 mAh battery, 24 C is enough. We'll bump it up to 30 C for good measure.

So, I can save money & not get the 60 or 99 C batteries.

Because anything more than 24 C is unutilized. Getting a extra 10 C does nothing for performance.

Instead of accusing me of over analyzing whilst you engage in complacency, kindly answer the bolded query above.

Calm down jam.
I'm sure you're nice guy in real life. As am I.
But my concerns are both valid & calculated & legit.

Knowing the answer is the difference between spending an additional $70 on batteries with excess C rating.
If I have to,I can but if I don't have to. I'd rather spend the extra on other things.

Thanks for your time.

Well like I said CONTACT A BATTERY MANUFACTURER !!!
I am a nice guy and while you may be also, you are ignoring others who have answered your query many times over.....
This forum exists to help and for friendship, you seem to think just because you have a degree in something you should get royal treatment and it does not work that way, your reputation on another forum precedes you and to be honest I am just not impressed by your actions, if the information that has been provided is not satisfactory to your needs follow the advice and contact someone like Max Amps..... they put together some of the finest batteries of all types and I am positive you will get an answer that is equally as long winded as your questions are....
Enough said on this subject..... This thread is now closed
