Hello fellow drone pilots. I have had a similar nightmare with Autel batteries for the EVO 1. I had three batteries that suddenly went bad after many successful flights and charges. Pure frustration dealing with Autel. After some digging, I have found a potential solution. I have located a battery provider that has a smart battery with additional capacity but the same weight of the OEM battery. I will purchase one and try it out. If it works as advertised, I will the company used so that we can all get back flying. I am saddened that Autel won't own up to what appears to be either a bad battery design or software issue. Love the drone but hate the service. Let me know what you think.
