I had nothing to measure temp with, but it was 35C ambient so I always thought on a cooler day that 100A wouldn't be out of the question....


Ok now that is weird. I am using the MM in my 1/10 buggy that weighs around 1.7Kg. Using watts up meter for peak current. Peaks at around 73A on 2 S lipo so I am thinking that average current is probably alot lower. 10 - 30A I supposed. With a fan, temp taken was around 61C at an ambient temp of 30-32C. I was told that a 60C MM in a 1/10 is the normal temp. I guess that is normal then. But considering current peaking at 73A on high traction surface, I am not really sure if the MM can handle 100A continuous without thermalling. Maybe I have a defected MM? I just got it as a replacement for an old MM in a non-warrenty claim and it looks totally brand new. As far as I remember, the old MM wasn't running as hot as this current one. Maybe it is the new firmware?
