Ok, i understand.
It all started like this. I am a computer engineer, work on laptops hardware problems.
So recently i come across battery repair modules such as NLBA1, EV2400. i bought EV2400 which can be used to reset both laptop and drones batteries when they are locked due to related cells problem. I take time much to watch tutorials from youtube and have good knowledge added to my engineering laptop before.

Thank you very much for the update as well.
If there is anything else that we can help with, please just feel free to let us know.
Thank you.

The drone is working as i have tried another battery with and it works well .
So this battery I try to fix is not perfect yet.

Hi,
I have a phantom 4 battery that when on the charger led 4 flashes 16 times fast and then 4 long then off. This repeats after several seconds.  Is this something that can be fixed?
I have read the battery led flash chart and it looks like I have low temp and high temp issues.  The battery is room temperature FYI.
Can this be fixed?

Thanks in advance

Follow up:  After about 1.5 hours on the charger then final long flashes stopped. Now it flashes 17 times fast and stops the repeats.
It is about 70 degrees f. Should I heat up the battery?
Thanks again

Hi, there.
Thanks for your update. May we know the color of the led when it flashes? Could you please send us a related video so that we can confirm the details asap and offer you better assistance?
Thank you in advance.

Hi Natalia. I have phantom 4 battery with LED 1 on and LED 2 flashing when switched on. When plugged into charger all LED goes off and comes back on after few seconds ,then repeats.

Why?
