Hello
What could be the problem? The cells are fine, the chip is unlocked, but it won't charge. Using the same charger, another battery charges without a problem and everything works fine (also on the drone).

Your other battery that charges is the same as this one?

@loliconic Hello, the download is complete, but unfortunately everything is the same.

Try to charge it using NLBA1, but let it charge for a longer time.
Wait about one minute on the charging tab.
Some batteries took a longer time to start charging.

@loliconic Hello, unfortunately I downloaded it and then ran a cell calibration and everything is still wrong.

I don't understand what you want to say.

I see from this photo that your battery is charging and discharging.
Please verify whether the battery connector pins have widened or become deformed, which may prevent proper contact with the charger.

You are a genius, it was my battery contacts, you opened it and connected it to the HUB without a case and it works perfectly now, Thank you
