Battery discharge temperature

[k9kids]

Much to my surprise when I took a battery from my GPC case it was in a discharge state and felt warm. So I got the digital temperature gun and measured the temp vs another battery that was in a normal state.

14 degree difference in temperature. 79.3 vs 93.3.

Didn’t expect that. The batteries are surrounded by foam and fit tightly into their slots.

I think from now on the batteries stay out of the case until it is time to go fly.

Just passing on my observations.

or don’t store them with a full charge. I always charge my batteries to ~60% after using them and store them like that.

I always fully charge my batteries when I plan to go fly. Then something happens and I cannot.

I too experienced this - and I also own a GPC case.

And now I also leave the batteries out of the case!

Stay safe.

No reason to leave them out of the case. The minor warmth is part of the normal, slow discharge process, to reach storage mode.

the batteries for our drones pack a lot of punch for their size ,and any time the chemical process from charging, or discharging,is in progress then heat is a by product of that process

I would suspect that’s how the auto discharge works. The battery converts stored energy to heat, how else could they have solved it? Where would the energy go?

So no need to worry. Although, if for some reason my batteries where auto discharging, I would probably take them out of their case.

It’s designed to do this, see entry #4 above

The manual is not stating how the magic of discharging works, it just states that it is normal to feel a moderate amount of heat coming from the battery while the discharge is in effect.

To me it’s obvious that the heat produced is not a byproduct from discharging, it’s the primary product.
