abnormal battery behavior

[Skeggia2025]

Battery charged to 100% (charged yesterday), I insert the battery, start the drone, after a few seconds it lands on its own due to low battery (0%) but all 3 cells are still at more than 4v.



I charge the battery (it was still cold) in about 20 minutes it tells me that it is 100% charged (strange), I connect it and start the drone again which performs 2 flights of about 8 and 5 minutes, landing with the battery at 8% and the 3 cells at around 3.65v (perfect fly mabe)

please give me an opinion, I was already ready to buy a new battery but I wouldn't want the problem to be anything else, firmware all updated today.

How many Batteries do you have? Is this the only battery that behaves like this?
Check the drones behavior with a different Battery- If the Other Battery works As it should Stop charging or using the "funny" Battery.
Is the Battery new? If so -Send it Back, It is Defective
I see no reason Other than The Battery itself For the Drone (or Battery) To Act this way.

Hi there & welcome to the forum

Share your flight log from that flight where the percentage went to 0% immediately... in there we can see exactly what happens with the voltage.

Go here & upload the log which is stored in the screen device you flew with --> PhantomHelp Log viewer
Then share the link they provide once you've uploaded in this thread, in a new post.

(Scroll down a bit there & they describe exactly where in your screen device the logs are stored)

ok I try

I have one battery and I've flyed without problem before.

Now I've recharged battery and fly, above 10minutes again.
If I use battery right away after charge, problem not is present. If I charge battery and disconnect battery from charger and fly after more hours I've problem.
But is strange that when the problem occurs, on battery is one led blink, 0% on system but voltage is more of 4v

aggiornamento, dopo altri 30 secondi di volo, la batteria è andata in ripristino, il LED della batteria non si accende. Comprerò il cp2112 per giocarci un po' (sono un tecnico e voglio fare qualche esperimento ) in più mi comprerò una batteria nuova perché non posso stare troppo tempo senza volare

mmm .. the batteries, as I was saying, seem good apparently, I think one has some anomalous drop for a short time and then he puts it at 0% even though it is charged. As I was saying, it's now under protection... I'll do some tests when the cp2112 arrives
