Nominal operating battery temperatures

[mpa]

Hey all,

Any one keep track of there battery temps during operation?
i fly in about 25-30 (86F) degree Celsius ambient temps with relatively high humidity (80% at times), my battery temps get up to at around 40degress (104F) within a few minutes of flight and stay that way? i have 3x battieres and all do the same. everyone else getting the same temps?

reason im asking is because i didn't think lipos get that hot unless really stressed from high current draw, i had much experience with my RC bashers in the past!

cheers

They ARE under pretty high draw, and also somewhat insulated in a plastic case.

No problem, a lipo is happy up to 60° or so.

Here is a snapshot of the temp trace log from a flight this weekend where ambient temps where around 90'F...

Whats the normal temp your batteries get during normal flight..?

I just saw mine hit around 55.2 degrees celsius.. Was a bit worried it will shutdown suddenly and drop from the sky or something
