I'm on the East Coast too Sailr:) so better keep on your toes! LOLkinda

It has nothing to do with the AMP or draw capacity. It has to do with the ability of a higher C battery to shove the volts through with more power....to be simplistic. If you have ever moved from a 20C battery to an identical one with 30C, you would see the incredible difference in the initial power. Once the pack bleeds off a bit then everything is equal.

also depends on prop and setup.....

hmmm not sure on the whole 20c verses 30 or 40c but i do know guys racing rc cars were going fine on 30c, a few tried 40c and blew esc,s up

[sailr]

Yep, the "C" rating DOES make a difference. ESC's that have been arounda while simply were not designed to take into account the 'surge' from the higher "C" batteries. At least we warn you about the one 30A we have that can't handle above a 25C!

[Brushless55]

they must be doing something wrong..
the guys who race down here run faster laps with 40c and 50c packs

[ozzie-crawl]

there brushless slash's, all i know is they were running same setups and killed esc,s after trying 40c packs

[Brushless55]

the higer C ratings produce less ripple and can actualy help the system ..
so if the esc is going, it must me junk, or not rated to what they state
every one around here runs high C rated packs with faster laps and cooler running systems

[Brushless55]

the fact remains, the motor will only pull the amps it needs!
batteries don't blow up escs

Bigpapa here is pitcure. For what it is worth.

[Brushless55]

Bigpapa, I do have these if any interest. 3s 2200mah 30c Bought new 9-12-09 $60 + shipping for all 6
Pm me if intrested.

Bob, awesome deal!

if the previous packs were not delivering the amps that the motor could draw because they were of a too low a C rating (or too low of a mah rating) the ESC may have been artificially protected. Once the high C packs were installed the motor was able to pull the amps that it wanted to, which is what killed the ESC.

Having said that, I'm not going to disagree with the designer of an ESC when he says not to run over 25C packs.

the esc of the brushless slash is said to be of bad quality.. they heat up easy even on 20c packs!
the VXL motor can pull some big amps like around 100+
the reason most are blowing them is because they gear wrong to get more speed, and that puts a bigger load on the esc..
most toss the stock VXL esc and go with a MM, much better esc over the VXL
so really not the batteries fault

A qualified ESC designer/electrical engineer would never ever ever ever ever ever say this. Realiticly you want a batery with an unlimited C rating,(highest possible C rating) thus no voltage drop and no voltage surges.

Voltage surges come from weak discharge current and is a prime reason of many ESC failures. Castle Creations specifically addresses this and has recommended running 2P for EVERY setup!!!!!!!
25C 5000mAh in 2 P is like running 50C 5000mAh in terms of discharge current available only. Realisticly it is still 25C @ 10 000mAh

Current in amps, is pulled by the motor and NOT pushed by the battery. If you have to reduce a C rating, you have the wrong setup. Bigmaxy is correct in saying the ESC may be artificially protected.

I agree Ryan..
Many MMM escs on the Revo have failed do to low C rated batteries
the Castle/Neu motors can pull some big numbers, and as for the VXL esc, that sucker is rated to 320amps and the motor 90-100amps max
I was not a believer in big C packs till I tried them in my 6XL Revo, now everything runs much cooler and much more power!
