I posted this over on RCU but thought I would put it here also. I had a concern of my packs being to hot from a test run on the bench the other night. I could hold them no probelm but they were hotter than I expected. Thanks in advance!
Here is what I posted on RCU;

OK so I know this has been asked a million times but here I go. I just want to make sure I understand this.
Set-up
Axi 2208/34 running 10X4.75
Jeti advance 18
Apogee 830 mah 2S1P ( Rated 9A cont. 12A Bursts )

Looking at the motor specs with that prop it should have only been pulling 6.6A ( Per H.L. website ) So should the packs have gotten warm at all? The Motor was pulling 6.6A and they (packs ) are rated to 9A So why did the pack get that warm?
Do I have to big of a ESC? ( 18A )
Am I getting overly concerned about nothing?

When I say the pack got warm, it was a little warmer than those hand wrmers you use in the winter. Like I said it was not "hot" but right on that border line. Thanks a million in advance for your answers!

if you want a real answer, you have to post it in the ezone on rcgroups.

Last I checked, most the people on ezone had decided that 140 degrees was the max acceptable temp, before they started noticing the packs performance decreasing.

Also, don't run it static (bench running) longer than to just see that it works. They draw a lot more juice if unable to move, like on a plane.
