I just did firmware update on my mavic pro and remote with no problem. After I did the update I wanted to put my other two batteries in the mavic to see if any battery update is required. Two batteries were fine but my third battery show battery error. There is nothing showing like a bad cell it just says error land as soon as possible. It even shows 90% charged and the temp is the same as the others. Any ideas what to do? Battery only has 8 charging cycles.
