Since my EVO was upgraded to V1.5.8, the first battery failure began to occur. After the next 3 months, all of my batteries showed battery damage warnings. I am using charging hub for charging. I have been using all the versions before V1.5.8 without any problems, only after upgrading v 1.5.8, it started until all the batteries showed damage. And also I found my battery will not automatically discharge since I upgraded to 1.5.8. Although I have set it to automatically discharge after 3 days, the battery is still fully charged after the past week.I found that starting from v18.104.22.168, the battery firmware has been updated. I tried to downgrade the EVO 1 and downgrade one of the damaged batteries to the previous battery firmware version. But unfortunately it has no effect. I have reason to believe that the latest V1.5.8 version may have some changes that may accelerate the aging of the battery or have bugs. Now I don't have any batteries to use, and I am very sad. Each of my batteries has been used about 30 times, and I don’t want to buy it again. Does anyone know how to replace the cells of the EVO1 battery? How to disassemble, thank you
I used my EVO in the Virgin Islands in 18' and 19' and used all three batteries in rotation maybe 10 to 20 cycles each then came home and stored the drone for one year. Took it out and now I have one battery showing the damage warning. Gee I hope my other two do not do what yours are doing. That sucks.
