HOT batteries

[m00se]

does anyone know the spec for how hot the battery can get in flight without it being a concern?
I know Lipos normally have a limit of around 60c.
mine were 61c yesterday just after flight......... and they didnt come out of the overheated protection mode for at least 2 hours when left in the shade and with a couple of fans passing air through the box they were in.

Does anyone have any experience here? I might have to make an UBER cooling box for them to cool them down in a more reasonable time. otherwise to do a couple of hours work is going to mean having a shed load of batteries on hand.

Check the User Manual, starting on page 19 for battery information.

EDIT: Also read side of battery under "WARNING".

hmm ok, so it says 71 c on the battery,,,,,, the manual only states lower end temp limits, couldnt see the higher limits.

So I have around 10 degrees, until its considered critical temp. thats at least promsing, although summer hasnt hit yet and the air temp will still go up at least 10 degrees more
