40c or 50c or 60c
 

Can you really tell the difference between a 40c, 50c, or 60c battery?

There is even a 65C and a 90C!

If you race in a stock class, then hell yeah you can tell a difference!
That 40C will feel nutless compared to a 60C or a 65C like I run!

But its all about if you race and what class do you race in?
For bashing your going to want more Mah over C rating... Longer time to bash!

Racing... More C equals more punch out of corners and more nuts to clear that "big tripple"...

It boils down to how much are you willing to spend? The protek batteries on amain are great and very reasonably priced! $90 for a 65C pack...
Also check out the gens ace packs! I hear the 50C is a nice pack but hard to catch them in stock! They sell out fast!

Battery
 

I race stock and mod buggy, from what I read everything state for ever 1c = 5amp. So a 40c would be 200amp.

My other question is how many amps does a Tekin RS Pro esc handle?

I would not worry about how many amps the rs handles. Batteries only supply the power needed for a given setup. The larger c batteries hold voltage better than the lower c so it give you more punch. The more amps you draw cause the voltage to drop faster. that is why a 13.5 motor seem to have more punch and maintain it for a longer time than a 6.5 which draws more current. Batteries only supply the power that is needed.

i like 50C.

As some said, stock classes you will absolutely feel the difference between 40 and 60c. Mod you probably won't.

Unfortunately there is no industry standard for "c ratings" so one companies "90C" may be the same as another's "50C" It's internal resistance that matters the most and none of the big manufacturers list that ratings on their packs so there is no way to tell other than running one to see which works best for you.

A battery gets juice "pulled" from the motor/car, it does not "push" amps or volts into the speedo. A 6000mah 60c pack can safely handle 360amps. The only car capable of pulling that kinda juice is maybe a Toyota Prius. So your speedo and motor are never getting 360amps. But the motor may pull 80amps peak and your battery will be able to provide it. The bigger % your system pulls of available to usable = the bigger drop in voltage leading to shorter runtimes and less "punch" This all has to deal with motor, gearing, surface traction, etc. Offroad buggies pull far less amps than onroad vehicles since the traction is generally not there comparatively.

Hope this helps.

Nue racer voltage will always be what it is at battery and speed control until you apply a load. Voltage is a constant.

for stock racing sure but for a 1/8 scale all you need is really at least 30/40 c if you cant clear a tripple with a "30c" rated lipo than theres something else wrong lol.

what im saying is a 4c lipo, with a 30c rating for a 1/8 scale has plently of punch but that does depend on what kind of "kv" motor you have actually.

a 2200 kv motor needs no more than a 4c /30c lipo omg.
oh yea its hard to know really on what the punch ratings on lipos really are anyways.

I'm not trying to be a jerk but it's 4s 30c. The higher the voltage the less amperage is need to create a given wattage or power.

Negative...

Google "Voltage Drop"

We wish voltage was constant - then we wouldnt care that much about IR, or C ratings :)

+1 on that!

I also like the negative, kinda reminds me of the terminator...

Yes voltage does drop when you apply a load on a battery.

I'm honestly not sure what you're trying to say here but as someone else pointed out and then you subsequently agreed with, voltage of a lipo is not constant when being used in a vehicle. So the better the pack holds voltage under any given load (i.e. less voltage drop) the more "punch" that pack will have.

I think I stated that with my first post with an example. The bigger the load the faster the voltage will drop.

i know personally notice the difference between 30c and 50c

the power that it can give a 50c is alot better lasts longer my 50c batteries are lasting longer than 30c

the only thing after 50c not sure if would notice much difference after that cause the motor can only draw some many amps
