Hi everyone,
I discovered a strange behaviour of my Mavic Intelligent Battery. Today I was using it (outside temperature around 25 degrees) when suddenly, after a restart, I got the error "Battery authentication failure". I tried to reinstall the FW via the Go App 4 (latest one .900) but it didn't work. After a few hours I tried again to switch on the Mavic and surprise: the battery was back! The authention error was gone, even after a couple of restarts. So, I did a short flight (monitoring the battery details, volts, temperature etc). After the flight I tried again to restart the Mavic and... The authentication error again appeared!! I did some tests even with my other battery. The problem seems to be related with the battery temperature. If the battery is cold the authentication works fine but, if the battery is slightly warm (more than 35 degrees) the authentication fails.
Next week I'll leave for holidays and I'll bring my Mavic. I already ordered a new battery, since I don't trust my faulty battery anymore. On September I'll contact the support.
If you ever experienced something similar try to cool the battery and try again. You may have the same issue of mine.
