85*C should be okay, thats still pretty damn hot and you wont likely heat them up that much under most normal circumstances. At worst, they will go pop and you'll have to get some different ones, but its probably worth trying them at anyrate.

Low ESR do have a lower internal resistance which allows them to be more effective in our applications than non-low ESR capacitors. Voltage ripple can be suppressed by low ESR caps, but regular caps won't do nearly as much for the ESC. Regular caps are more of a helper to the batteries than the ESC.

The temperature rating doesn't really matter here, as regular caps are pretty much always rated at 85 deg. C, but all low ESR caps are rated at 105 deg. C to my knowledge.

Can you tell me how can i know if my cap are a low ESR???
On mine, the only thing i can see on it is 105deg, 50V, 3200uF.....
And what does mean ESR

E=?
S=?
R=?

If its rated for 105*C, chances are its low esr.

OK good, but can you tell me the advantage to put this capacitors on the input lead of the MM??
I run it on 4s on a crt.5. should i realy need it???
And i've a fan on my MM.
For now, i've my MM in my slash with a Neu 1509 2700Kv, on 3s and after a good 30 minutes of hard bashing, the ESC is about 100 degre..
