Just now,

I put the batteries under charging.
I tried or speeded up charging a little, as does a friend with his DJ Spark.

Put the batteries in the freezer for 5 minutes to lower their temp (no below 0 C)

the first started charging the second is not. Unplugging and recharging no signal.

Then I decide to put it on the spark. Turn on the spark, it works.

I put to charge the battery together with the spark ..

And she gets loaded ...

But I do not think it's the freezer's fault after all, the batteries were 10 ° C.

Had I read somewhere that they went to hibernation?

That this is happening?

Thanks for the answers you propose.

I think putting them in the freezer is a bit stupid to be honest, the hot and then freezing cold with cause condensation. I would bin the batteries and buy new if I was you, this is not a safe way to fly.

Condensation is created if there is a great temperature swing.

But I used the batteries yesterday, not today.

Ambient temperature is about 26 ° C

Removed from the freezer I waited 2 minutes.

Okay, I do not use the freezer anymore ..

I do not want to unleash the world against me.

but if charge battery at November? 10°C ambient temp...? no create a condensation?

Ahh not to bad then ! Its not a big deal, I'm just a little confused by putting the batteries in the freezer will speed up charging ? Is this a thing with LiPo batteries

Ahh non male poi! Non è un grosso problema, sono solo un po 'confuso mettendo le batterie nel congelatore accelerare la carica? È una cosa con le batterie LiPo

LiPO below zero will ruin ..

But above zero no.


  It is advisable not to discharge the batteries to the maximum and too fast, if possible, don't use the devices at excessive temperatures.

A second spare battery that you use less,
  Or if you are not going to use the main battery for a long time,
  Leave a residual charge around 50% and place it in a dry, clean, and possibly very cool place

The fridge is fine, the freezer no (ops my error)

Could you please provide a short video about this issue for better assistance?

Hes not going to kill batteries buy sticking them in freezer for 2 minutes...all he is trying to do is get overtemp down so he  dont have to wait the 10 to 15 min to charge. I would advise against this tho

I put my battery in spark and charge of work ...

But too long, because I use fastcharge USB (included in fly combo).
stopped charging, remove the battery from the spark, put it into fast charge and finally work.

Yesterday tried the battery no problem.

tnks 4 now
Inserting both batteries into the fast charge yesterday, only one went.

But then doing as described above worked ...

Yes, he will. 2 mins wont cool the entire battery, just the outside, fooling the sensor.

Hes dangerously charging hot batteries.

Glad to hear that , hope you can enjoy the drone, happy flying!

Glad to know your on here, i Personal messaged both you and djimindy an hour ago and still no response, please respond.

Hes dangerously charging hot batteries.

I usually fly ... then reloading the next day shortly before flying again.

So the batteries were not hot ... max temp 26 °C

and how this is related to speeding up things if the battery is 26 from the start i ask ?
